Satsume — the IPO layer for creators.
Own a piece of the creators you already support. Satsume lets creators launch tokens tied to their actual revenue — and fair-launch mechanics like Community Mining make sure those tokens land with real customers first, not bankers, insiders, or bots. Community investment in the creator economy, opened up to everyone.
01 Introduction
You watch every stream. You bought the hoodie the day it dropped. You shared the post before the algorithm did. When the creator blows up, your friends are surprised. You aren't — you were there first.
And you get nothing for it.
Tips are gone the second you send them. Subscriptions reset every month. Early support — the thing you have the most of — has no upside, no ownership, no transferable value.
Most launchpads don't fix this. They issue tokens with nothing behind them: memes, hype, exit liquidity. By the time a real fan hears about it, bots have already cashed out.
Satsume is different. It's the first place where the people who already support a creator can own a piece of their future — backed by the creator's actual revenue, not a concept.
We are two things in one:
- A launchpad where a creator issues their own coin — backed by their actual revenue, not a concept.
- A full-stack engine (called CommerceOS) where that revenue is earned: storefronts, tips, subscriptions, drops. Every dollar that flows through CommerceOS automatically buys back and burns the creator's coin.
The result: the creator's success becomes your gain. No spreadsheets. No VCs getting first dibs. Just a direct line from "I like this person's work" to "I own a piece of their future."
The Satsume protocol is currently running on Sepolia under the Mindverse Genesis testnet phase. Anyone can join with a wallet — no real funds required. See the Testnet guide.
02 The shift
Token launches today are designed for traders, not fans.
First block: bots snipe. Second block: insiders dump. By the time a real follower hears about the token, the price has already peaked and crashed. The community gets nothing except a lesson in pain.
Satsume flips this.
Phase 1 — Community Mining — the bonding curve is closed. The only way to earn the creator's coin is to actually use what they sell: buy the hoodie, tip the stream, subscribe to the newsletter. Consumption mints the coin. No bots, no front-running, no "friends and family" round.
By the time trading opens, the supply is already held by real customers — people who care about the creator, not mercenaries who will dump at the first green candle.
This one change rewires everything. The fan now has an information and economic advantage over the speculator. That has never happened before in crypto.
03 The big idea
Three simple bets:
- A creator's coin should be backed by their revenue. Every dollar that comes into CommerceOS (after promotions) sends 10% to buy the coin off the market and burn it. More sales → fewer coins → each remaining coin is worth more. No magic, just math.
- The first holders should be real customers. Community Mining makes that true. You can't snipe what you have to earn by buying a t-shirt or sending a tip.
- The launchpad and the revenue layer must be the same system. Otherwise the buyback is just a promise, not a protocol. Satsume wires them together at the contract level. The creator can't skip the buyback — it's built into every transaction.
That's it. Three decisions that turn a creator's economy into an investable asset — without Wall Street, without gatekeepers, and without requiring fans to become quants.
The token's value floor is set by the buyback flow. The token's ceiling is set by the creator.
04 The Launchpad
The Satsume Launchpad issues Creator Coins. Each Creator Coin is a separate ERC-20 with:
- A fixed total supply of 1,000,000,000 tokens (1B).
- A four-phase launch process: Community Mining → bonding curve → migration → Uniswap V2.
- An automatic buyback engine funded by a configurable share (default 10%) of the creator's net revenue through CommerceOS.
- A transfer tax built into the token contract (default 1%) that persists across the bonding-curve and AMM phases.
- A 10-year lock on liquidity post-graduation.
The launchpad's quote currency is USDI — a stablecoin minted 1:1 from NUSD (the testnet point/payment unit) on testnet, and routable to SUME on mainnet. USDI is transfer-restricted (whitelist-only outside of platform operations) so the protocol can sponsor onboarding without leaking the token off-platform.
Every launch goes through the same four-phase machinery. There is no "private round", no insider price, no pre-listing OTC. The first hour of a Satsume launch looks exactly like the last hour: deterministic, on-chain, equal-access.
05 Creator Coins
A Creator Coin (we call the variable X in this document) represents a claim on the success of one creator's economy. Per launch:
| Parameter | Value |
|---|---|
| Total supply | 1,000,000,000 |
| Bonding curve allocation | 950,000,000 (95%) |
| Platform airdrop | 50,000,000 (5%) — locked until graduation |
| Initial virtual reserve (USDI) | 250,000,000 |
| Graduation threshold (USDI in curve) | 2,000,000,000 (≈1.75B contributed) |
| Launch fee | 10,000,000 USDI |
| Creator pre-purchase cap | 90% of supply (fast-track if > 80%) |
| Baseline trading fee | 0.6% on buys and sells (50% creator · 50% platform) |
| Ticker | Up to 5 alphanumeric characters |
Supply is monotone non-increasing
The protocol burns excess X during migration to equalize the bonding-curve and AMM prices, and continues to buy-and-burn from creator revenue indefinitely. There is no inflation, no admin mint, and no dilutive treasury issuance. Effective FDV is always less than the 1B headline number — sometimes much less, depending on how much was burned at migration.
Creator and team pre-purchase
The creator can pre-purchase up to 90% of supply before public launch, priced along the same bonding curve everyone else faces. Pre-purchased X is held under an on-chain vesting schedule with a configurable cliff and duration (testnet defaults: 6-month cliff, 6-month linear vest after the cliff). There is no separate "team token tranche" beyond the creator's pre-purchase.
Airdrop allocation
The 5% airdrop allocation is minted at the start of Community Mining and locked until AMM migration. After migration it is unlocked for platform use; on mainnet, the unlock funds a distribution to SUME stakers. The testnet does not distribute the airdrop pool.
06 Why revenue-backed
Most launchpad tokens have no connection to a real business. Their value is driven by hype and exit liquidity; the issuer's job ends when the token lists. Satsume Creator Coins are different by construction.
Each Creator Coin is tied to a programmatic buyback funded by the creator's actual revenue. The accounting is simple: of every dollar (denominated in NUSD on testnet, USDI/SUME on mainnet) that lands in the creator's CommerceOS, 10% of the net — after deducting promotion liabilities — flows to a buyback contract. The buyback contract uses that capital to buy X on the open market and burn it.
As the creator's revenue grows, three things happen:
- Circulating
Xcontracts. - Remaining holders' share rises.
- The buyback flow itself grows in absolute terms, accelerating the cycle.
This is the flywheel: more revenue → more buybacks → tighter supply → more holder advocacy → more revenue. Importantly, the flywheel does not need speculation to spin. It turns at exactly the speed of the creator's actual business growth. Speculation can accelerate it; nothing on the design side requires it.
07 Community Mining
Community Mining is the headline innovation of the protocol. It is the design decision that makes a Satsume launch rug-resistant.
What it is
For a minimum of three days at the start of every launch, the bonding curve is closed to direct buys. The only way to receive the creator's token is to spend at the creator's CommerceOS.
When a customer pays for something at the CommerceOS — a product, a tip, a subscription, a token-gated unlock — 10% of the net payment (after any promotion payouts) is routed through the bonding curve. The X bought with that 10% is credited to the customer, not the creator. Tokens are mined by consumption.
The X earned this way is non-transferable until Phase 2 opens. There is no way to flip it during Phase 1. The protocol enforces this at the contract layer.
Why this changes everything
A typical launchpad's first buyers are bots running scripts faster than humans can read the announcement. They buy in the first block, sell in the second, and the creator's audience is left holding a token whose price has already round-tripped. The supply is concentrated in mercenary hands within minutes.
On Satsume, the first buyers cannot be bots. They have to be customers. The bot has to:
- Actually buy the product (or pay the tip / subscription / unlock).
- Take delivery or consume the service — there is no shortcut around a real transaction.
- Receive a non-transferable token that cannot be sold until Phase 2.
By the time anything is sellable, the speculator has spent more on the product than they can possibly recoup from a flip. The economics simply do not work for them.
For the creator's actual fans, the math is the opposite. They were going to spend at the CommerceOS anyway. The protocol just rewards them for doing it during the right window. For the first time, the creator's audience has an information and economic advantage over the bot — and the protocol structurally encodes that advantage.
Community Mining ends when the creator (or an authorized keeper) calls startPhase2() after the configured minimum duration has elapsed. The contract does not auto-advance — the gate is explicit and on-chain.
08 Phase lifecycle
Every launch passes through four phases. The phases are gated — the protocol does not transition automatically when a threshold is crossed; an explicit transaction must be sent.
Phase 1 — Community Mining
Already described above. Minimum 3 days. Bonding curve closed to direct buys. CommerceOS purchases mine X for customers. 10% of net revenue routes to bonding-curve buybacks. Mined X is non-transferable.
The standard 0.6% trading fee applies to the bonding-curve buybacks executed from CommerceOS revenue (there are no public buys to apply it to).
Phase 2 — Open trading on the bonding curve
The bonding curve opens. Anyone can buy and sell X using USDI.
- Sniper tax applies to buy orders only. Starts at 89%, decreases linearly by 1% per minute until it reaches 0 (~89 minutes after Phase 2 begins). Goes 100% to the platform — creators do not earn the sniper tax (otherwise they could wash-trade with a second wallet during the window).
- 0.6% baseline trading fee on both buys and sells, charged in USDI, in addition to any sniper tax on buys. Split 50/50 — 0.3% to the creator, 0.3% to the platform.
- The creator's 0.3% share is claimable at any time.
- Sniper-tax proceeds are held in USDI by the platform and locked until migration to seed the AMM pool.
- 10% of CommerceOS revenue continues to fund the buyback pool. Buy-and-burn can run on the bonding curve during Phase 2 — buybacks do not have to wait for AMM migration.
- TWAP and trade-size guardrails (1-hour window, max deviation, staleness limits) cap manipulation during open trading.
The 89% starting sniper tax mirrors the effective 90% "tax" that Phase 1 imposed on consumption-mined X (only 10% of spend went toward the token). The intent is symmetry: in the first minutes of open trading, the speculator faces the same effective burden as the customer did during mining. After ~90 minutes, the playing field levels.
Phase 3 — Transfer / migration
When the bonding curve's total reserve reaches 2,000,000,000 USDI (~1.75B contributed plus the 250M virtual reserve), the token becomes eligible for migration. Phase 3 is a controlled transitional state — the protocol completes a series of pre-AMM operations in order before liquidity is locked:
- Convert sniper tax: the locked USDI is swapped for
X; 100% to the platform (used to seed the initial LP). This fixes the graduation price. - Price equalization burn: excess
Xis burned so the bonding-curve exit price matches the intended Uniswap launch price. - Final buyback burn: the accumulated buyback pool is used to buy-and-burn
X— finishing the buyback work before liquidity is committed. - AMM creation: remaining USDI and
Xare paired and deposited as initial liquidity on a Uniswap V2-style pool via the configured router. The protocol receives the LP tokens. - Tax configuration: the post-graduation transfer tax (1% buy / 1% sell, paid in
X) is wired up on the token contract for the new pool. - LP lock: the LP tokens are locked for 10 years (3,650 days) to a burn-style lock address.
Phase 3 is triggered by an explicit on-chain transaction — same as Phase 1→2. The threshold being crossed does not auto-execute migration.
Phase 4 — Graduated (Uniswap V2)
Xtrades freely on Uniswap V2. LP locked for 10 years.- 1% buy + 1% sell tax built directly into the token contract (no Uniswap hook, no separate fee router). The token contract detects buys/sells by checking whether the counterparty is a known liquidity pool, and accumulates the tax in
X. The contract automatically swaps accumulated tax tokens for the paired asset and forwards proceeds to the creator (70%) and platform (30%). - 10% of CommerceOS revenue continues to fund the buyback pool. The pool's burn function is callable by a configurable owner contract — testnet default is a weekly scheduler (Friday 9pm Beijing time) that triggers buyback-and-burn.
- The post-graduation buyback executor is exposed for keeper/scheduler integration. Buybacks are deflationary forever — supply only ever decreases from this point.
09 Tokenomics & parameters
The full parameter set for a Creator Coin launch:
| Parameter | Value (testnet default) | Notes |
|---|---|---|
| Total supply | 1,000,000,000 | Monotone non-increasing post-launch |
| Bonding curve allocation | 950,000,000 | 95% |
| Platform airdrop | 50,000,000 | 5%, locked until graduation |
| Initial virtual reserve | 250,000,000 USDI | Seeds the bonding curve |
| Graduation reserve | 2,000,000,000 USDI | ~1.75B contributed |
| Launch fee | 10,000,000 USDI | Paid at launch |

| Ticker length | ≤ 5 chars | Alphanumeric |
Revenue-to-buyback calculation
The percentage routed to buyback is computed after deducting promotion liabilities. For example, if a creator runs a Drawing promotion that allocates 10% of sales to a raffle prize pool, and a user pays 100 NUSD:
// 100 NUSD spent at a CommerceOS with a 10% Drawing allocation
prize_pool_share = 100 * 0.10 // = 10 NUSD → Drawing prize pool
net_revenue = 100 - 10 // = 90 NUSD
buyback_share = net_revenue * 0.10 // = 9 NUSD → buy X via bonding curve
Launchpad Points
Separate from the Neurobits points system that tracks CommerceOS engagement, the launchpad maintains a Launchpad Points tally:
// Launchpad Points = current USDI value of the user's full token portfolio
launchpad_points = sum(holdings[token] * usdi_price[token])
Launchpad Points are denominated in USDI and update as portfolio composition and prices change.
10 Trading & fees
Three distinct charges apply across the launch lifecycle. They are summarized here to keep them straight:
| Charge | When | Paid in | Where it goes |
|---|---|---|---|
| Sniper tax | Phase 2 buys, first ~90 min | USDI | Locked pool → converted to X at migration → 100% platform (seeds LP) |
| Baseline trading fee (0.6%) | Phase 2 buys + sells | USDI | 50/50 creator (0.3%) / platform (0.3%) |
| Post-graduation transfer tax (0.6%) | Phase 4 buys + sells | X (auto-swapped to paired asset) | 50/50 creator (0.3%) / platform (0.3%) |
| Buyback flow | Phase 1, 2, 4 (continuous) | USDI on curve, X on AMM | Burned |
The buyback flow is not a fee — it's the structural revenue-to-token routing that defines the protocol. The other three are platform / creator revenue.
11 Why full-stack
Most launchpads stop at the token. They issue, list, and walk away. Whether the token is actually backed by anything — whether the creator's revenue ever touches the buyback contract — is left as an exercise to the issuer. In practice, that exercise rarely happens.
Satsume can't stop at the token because the token only makes economic sense if the revenue can route automatically, verifiably, and without the creator having to wire money themselves. That requires the launchpad to also own the layer where the revenue is earned. We call ours CommerceOS.
Owning both halves of the stack lets us do three things that token-only launchpads cannot:
- Enforce the buyback flow at the protocol level. Revenue from CommerceOS is split into the buyback pool by the smart contract that receives the payment — there is no off-chain bookkeeping the creator could quietly skip.
- Run Community Mining at all. A consumer-first first-phase only works if the protocol can detect consumption. With CommerceOS in the picture, every CommerceOS payment is a consumption event the launchpad can credit.
- Support promotion primitives that lock fans in. Drawings, drops, group-buys, and revenue-share NFT Receipts all need an on-chain commerce layer underneath. CommerceOS provides it.
12 CommerceOS — the revenue layer
CommerceOS is the on-chain commerce and engagement layer that sits between a creator and their audience. It is where money changes hands. Every revenue event in the Satsume ecosystem flows through it, and from there into the buyback engine.
What CommerceOS handles
- Storefronts — listings, orders, fulfillment, reviews, refunds.
- Tips and one-time payments — settled on-chain like any other purchase.
- Subscriptions — recurring on-chain charges with the same revenue-split logic.
- Token-gated unlocks — content accessible only to holders of
Xabove a threshold. - Pay-per-view drops — single-unlock purchases tied to NFT Receipts.
- Promotion mechanics — Drawings, Seeds, Saplings, Snowballs, Perpetual Drawings (see below).
What CommerceOS isn't
CommerceOS is not just a marketplace. The current Testnet hosts a physical-goods marketplace as the first integration because it was the most boring, lowest-risk way to prove the mechanics. But CommerceOS is a settlement layer, not a product category. The same contracts will host streaming tip jars, paywalls, subscriptions, and patronage tiers — anything where a creator earns from a transaction with their audience.
The structural property
Whatever sits on top of CommerceOS — a t-shirt sale, a $5 tip, a paid newsletter post, a stream sub — the protocol-level behavior is identical:
- Customer pays the creator through a CommerceOS contract.
- An NFT Receipt is minted to the customer (see next section).
- Promotion liabilities are deducted (if any active promotion applies).
- 10% of the net revenue is routed to the launchpad's buyback contract.
- The remainder settles to the creator.
This is the connective tissue between the two halves of the protocol. Without it, the launchpad is just another bonding-curve launcher. With it, every dollar a creator earns is structurally pulling on their token.
13 NFT Receipts
Every transaction at a CommerceOS mints an NFT Receipt to the customer. The receipt is more than proof of purchase — it is a programmable asset with two layers of value.
Dual-layer value
- Collectible & social. Like a traditional NFT, the receipt is verifiable proof of early support and can accrue collectible or social worth as the creator grows.
- Programmable economic rights. The receipt can carry on-chain payouts tied to the creator's future performance — for example, a perpetual revenue share from a specific product line, or eligibility for raffle prize pools.
How payouts work
The receipt's economic rights depend on the promotion type that minted it. A Sapling receipt carries a perpetual revenue share from the product it was bought against; a Drawing receipt is a weighted entry into a prize pool; a Snowball receipt earns automatic rebates as group-buy milestones are unlocked. All payouts settle on-chain — there is no manual claim against the creator.
Because every transaction is on-chain, every cash flow tied to an NFT Receipt is transparent, tamper-proof, and mathematically fair. The creator does not have to be trusted to honor the receipt; the protocol enforces it.
14 Promotion primitives
CommerceOS supports five promotion types out of the box. Each one mints a different kind of NFT Receipt with different payout logic.
| Promotion | Mechanism | What it's for |
|---|---|---|
| Drawings | A configurable portion of each sale funds a prize pool. Once the pool hits its threshold, a verifiable random function selects a winner from receipt holders. Each eligible purchase mints a receipt = one entry. | Virality and customer acquisition. Sharing accelerates the draw. Anyone can trigger the draw once eligible and earn 1% of the pool (capped at 10K NUSD on testnet). |
| Seeds | Transparent, trustless crowdfunding. Funds release to the creator only if a collective goal is met within a time window; otherwise refund. | De-risking new product launches. Backers know their capital is only at work if the project clears its bar. |
| Saplings | Early purchasers receive an NFT Receipt that grants a perpetual revenue share from all future sales of the product line. | Loyalty and word-of-mouth growth. Early adopters become lifelong stakeholders. |
| Snowballs | The product's price decreases for everyone as sales milestones are reached. Early buyers receive automatic rebates for the difference. | Collaborative demand generation. Turns customers into an aligned sales force. |
| Perpetual Drawings | Early supporters receive receipts that grant entry into all future raffles for a product line, not just the one they bought into. | Solving cold-start. Early support stays valuable indefinitely; recurring engagement. |
The promotion engine is composable: a CommerceOS can run multiple promotion types simultaneously on different products. New promotion types can be added without changing the core protocol — each is a contract that conforms to the CommerceOS promotion interface.
15 Beyond commerce
The current Testnet implements CommerceOS as a physical-goods marketplace because that was the most boring possible integration to test. We wanted to prove the mechanics work on the boring case before claiming they work on the interesting ones.
The same primitive supports any creator economy where revenue can be settled on-chain:
- Streaming tips. A tipper's payment routes through CommerceOS the same way a product purchase does — mints an NFT Receipt, deducts promotion liabilities, routes 10% to buyback, settles the rest to the streamer.
- Subscriptions. Recurring on-chain charges using the same revenue-split logic. Each cycle, an NFT Receipt is minted (or updated) and the buyback flow fires.
- Pay-per-view content. Drops with single-unlock receipts that may carry their own revenue-share rights.
- Token-gated everything. Content, communities, and unlocks gated by holding
Xabove a threshold. - Patronage tiers. Staked-token access — fans lock
Xfor membership benefits; staking reduces effective supply, accelerating the buyback flywheel.
The Community Mining property holds across all of them. A streamer's first X holders are the people who tipped during the launch window. A subscription service's first holders are the people who subscribed. A paywalled writer's first holders are the people who paid for a post. The first holders are always the people who used the service.
16 For creators
Who this is for
Streamers, writers, musicians, podcasters, brands, shops — anyone running a real revenue-generating creator business. The protocol does not care about your platform of origin. It cares about whether you can route revenue through CommerceOS.
Launching a Creator Coin
- Set up your CommerceOS. Create your account, switch to creator mode, list whatever you sell (products, tips, subs, posts, drops).
- Configure your launch. Pick ticker, set Phase 1 duration (≥ 3 days), optionally pre-purchase up to 90% of supply along the bonding curve, configure your pre-purchase vesting cliff and duration.
- Pay the launch fee. 10,000,000 USDI. On testnet, USDI is sponsored by the platform for approved creators.
- Announce. Once Phase 1 starts, the only way anyone gets your token is by spending at your CommerceOS. Drive customers there.
- Advance phases. After ≥ 3 days of Community Mining, call
startPhase2()to open the bonding curve. After the curve reaches its graduation reserve, call the migration function.
Revenue sources during Phase 1
The headline channel during Community Mining is your CommerceOS. But you can layer promotion types on top to amplify customer acquisition:
- A Drawing turns marketing into a game — fans share to fill the pool faster.
- A Sapling rewards your earliest customers with a perpetual revenue share, deepening loyalty in your most valuable cohort.
- A Snowball creates group-buy dynamics — fans recruit fans to unlock better prices for everyone.
The buyback share is calculated after promotion liabilities, so running active promotions does not break your buyback flow — it just sequences the obligations.
17 For supporters
What you can do during Community Mining
Spend at the creator's CommerceOS. 10% of your net spend mines X for you automatically. The earned X is non-transferable until Phase 2 — you mine, you don't trade.
Buying after Community Mining
- Phase 2: buy
Xdirectly with USDI on the bonding curve. Be aware of the sniper tax — it decays from 89% to 0% over ~90 minutes. - Phase 4: trade freely on Uniswap V2 with the standard 1% transfer tax.
What you actually hold
A revenue-backed claim. As the creator's business grows — more CommerceOS sales, more tips, more subs — the buyback flow systematically removes X from circulation. You're not holding a meme; you're holding a position in a real revenue stream with deflationary mechanics.
Launchpad Points
Your Launchpad Points = the total USDI-denominated value of your token portfolio. Points update as your holdings and the underlying prices change.
18 Testnet — overview
Everything described in this whitepaper is running today on the Sepolia Testnet under the Mindverse Genesis phase. You can experience it end-to-end with no real funds.
What you can do today
- Earn Neurobits (points) by spending at testnet creator storefronts.
- Run daily check-ins to claim
NUSD(the testnet payment unit). - Buy items, leave on-chain reviews, mint NFT Receipts.
- Become a creator and set up your own CommerceOS.
- Run a Drawing promotion.
- (Q1 2026) Launch a Creator Coin once the launchpad rolls out on Testnet.
What you'll need
- A wallet (MetaMask, Rabby, Trust, Rainbow, Ledger, etc.) on Ethereum L2 / Sepolia.
- A small amount of Sepolia ETH for gas — claim free from the Discord
#faucetchannel. NUSDfor marketplace spend — earn it via daily check-in atsatsume.com/genesis.
Nothing here touches real assets. The testnet is a closed simulation of the mainnet design, used to stress-test the contracts and the user experience.
19 Wallet setup
Satsume is non-custodial — your wallet is both your login and the place your assets live. We never see your keys.
Pick a wallet
- Browser extensions: MetaMask, Rabby
- Mobile: Trust Wallet, Rainbow
- Hardware (advanced): Ledger, Trezor
Setup checklist
- Download only from the official site or app store.
- Follow the wallet's official setup flow. Don't skip the recovery-phrase step.
- Back up your recovery phrase offline — on paper, or to a hardware backup. Never type it into a website.
- Never share your recovery phrase. The Satsume team will never ask.
If compromised, the holder has full control of your wallet. Treat it the way you would treat physical cash: store it offline, never in a screenshot or cloud file.
20 Get test tokens
Two assets are needed on the testnet: Sepolia ETH for gas, and NUSD for marketplace spend.
Sepolia ETH
- Join the Satsume Discord.
- Open
#faucet. - Run
/faucet. The bot will send Sepolia ETH to your address.
NUSD
NUSD is the testnet payment unit. You earn it through daily check-ins (next section). Once received, you may need to manually import the token in your wallet on Sepolia — the contract is:
0xcF10A5FB2fF625Dfed3E513221650fE6b04d51Be
Failed transactions don't deduct either NUSD or Sepolia ETH — the transaction simply reverts. Try again.
21 Daily check-in
Check-in is the primary on-ramp to test currency on the Genesis Points System. Connect your wallet at satsume.com/genesis and check in once per day.
- Each check-in mints a small allotment of
NUSDto your wallet. - NUSD is spendable at any testnet CommerceOS.
- Spending at creator storefronts is what earns Neurobits: the testnet rule is 1 Neurobit per 1,000 NUSD spent.
- Occasional check-ins also mint Mystery Boxes — unlock cosmetics, access, or limited events.
The full loop is: check in → earn NUSD → spend at creator storefronts → earn Neurobits → unlock tiers.
If a check-in fails, the most common causes are (1) you don't have Sepolia ETH for gas, or (2) your wallet isn't on Sepolia. Fix those and retry; if it still fails, the Discord support channel is the fastest path.
22 Try the marketplace
The testnet CommerceOS marketplace is a working end-to-end implementation of every protocol mechanic — minus a real Creator Coin launch (that ships Q1 2026).
What to try
- Browse upcoming Drawings on the homepage. Each card shows the prize pool, progress, and bound products.
- Buy an item that's bound to a Drawing — you'll receive an NFT Receipt that doubles as a raffle entry.
- Watch a prize pool fill. Once it crosses its threshold, anyone can trigger the draw and earn 1% of the pool.
- Leave an on-chain review after your purchase. Reviews feed the Trust Engine — a decentralized reputation layer.
Common gotchas
- You need NUSD and Sepolia ETH at checkout. NUSD pays for the product; ETH pays for gas.
- You must check out with the same wallet you logged in with. The system attributes purchases by wallet.
- Each order counts as one purchase, regardless of items in cart — important for quest tracking.
- Smaller purchases (e.g., 1 NUSD) won't accrue points if they round below the 1,000 NUSD per Neurobit threshold.
23 Become a creator
The testnet supports a creator role (currently labeled "Seller" in the UI for legacy reasons). It lets you operate a CommerceOS, list products or services, and run promotions.
Eligibility
Your account becomes eligible after a baseline of testnet activity. When eligible, a Become a Seller button appears on your account dashboard. If you don't see it, keep exploring the testnet — buying, reviewing, checking in — and you'll qualify.
Conversion flow
- Click Become a Seller.
- Enter an email you have access to — this is your seller-portal login.
- Confirm the role switch. This is one-way — you can run your CommerceOS from a creator account permanently, but you cannot revert to a buyer-only account.
- Click Launch Portal to open the Seller Portal.
Once you're in
- Set up your CommerceOS profile.
- List products, services, or content drops.
- Configure promotion bindings (e.g., bind a product to a Drawing).
- (Coming) Initiate a Creator Coin launch directly from the portal.
24 Run a Drawing
Drawings are the most popular promotion type on the testnet — they create on-platform virality at very low operational cost.
For creators (running a Drawing)
- In the Seller Portal, create a new Drawing promotion.
- Bind one or more products to the Drawing. Only purchases of bound products count toward the pool.
- Set the prize pool ratio — the percentage of each bound-product sale that flows to the pool. Example: 20% means every 100 NUSD spent adds 20 NUSD to the pool.
- Set one or more prize pool thresholds. Each pool accumulates independently and becomes drawable independently once it crosses its target.
- Publish. The Drawing now appears on the homepage's Upcoming Drawings rail.
For participants
- Browse the homepage's Upcoming Drawings rail or hit All Promotions.
- Click into a Drawing collection. You'll see the active pool, progress, bound products, and minted receipts.
- Buy a bound product. You receive an NFT Receipt = one weighted entry. Your win probability is proportional to your total eligible spend.
- Once a pool crosses its threshold, the Open Drawing button appears. Anyone can click it — including non-participants — and earn 1% of the pool for triggering the draw (capped at 10,000 NUSD on testnet).
The draw
Triggering the draw signs an on-chain transaction. A verifiable random function selects the winner from receipt holders, weighted by spend. 99% of the pool goes to the winner; 1% to the address that triggered the draw. Pool status updates to reflect the result.

27 FAQ
Why "Community Mining" instead of a fair-launch sale?
A "fair launch" where anyone can buy in the first block is fair only in name. The first block is dominated by bots. Community Mining is the only mechanism we know of that structurally locks out bots in the first phase — because bots cannot consume.
What stops a creator from selling their own product to themselves to mine the token?
The creator's pre-purchase channel already lets them acquire up to 90% of supply directly along the bonding curve, with vesting. Buying from oneself through the CommerceOS would cost the launch fee plus the trading fees plus the time of running the order, all to obtain something they could have bought cheaper through pre-purchase. The mechanism is not economic.
Can the buyback share be changed after launch?
The creator can raise the buyback share at any time. They cannot lower it. This is enforced by the connector contract, not by social commitment.
What if the creator stops earning?
The buyback flow falls to zero. The token continues to trade on Uniswap, valued accordingly. The 10-year LP lock means there is always liquidity to exit against; there is no scenario where the pool is yanked.
Why is USDI transfer-restricted?
USDI is the launchpad's quote currency. We need to be able to sponsor onboarding (e.g., front a creator their launch fee) without USDI leaking off the platform and being used for unrelated activity. The whitelist is wide enough to cover normal use; it exists to give us a kill switch for abuse.
Will Creator Coins ever be available outside Satsume?
Yes — Phase 4 puts them on Uniswap V2. Any wallet, any DEX aggregator, any block explorer. The launchpad is opinionated; the token is not.
What's the relationship between Neurobits, Launchpad Points, and SUME?
Neurobits measure your engagement with CommerceOS (testnet only). Launchpad Points are the USDI-denominated value of your token portfolio. SUME is the platform token on mainnet — governance and staking. These are three separate systems; only the third is monetary on mainnet.
28 Glossary
| Term | Definition |
|---|---|
| Bonding curve | The price-discovery mechanism for Phases 1 and 2. Price increases with the cumulative amount of USDI deposited. |
| Buyback flow | The protocol-level routing of 10% of net CommerceOS revenue into buys of X via the bonding curve (Phases 1, 2) or the AMM pool (Phase 4). All bought X is burned. |
| Community Mining | Phase 1 of every launch. The bonding curve is closed to direct buys; X can only be earned by spending at the creator's CommerceOS. |
Creator Coin (X) | The token issued by a creator on the Satsume Launchpad. Fixed supply, revenue-backed via buybacks. |
| CommerceOS | Satsume's on-chain commerce and engagement layer — the place where the creator's revenue is actually earned and where promotion mechanics live. |
| NFT Receipt | The receipt minted for each CommerceOS transaction. Dual-purpose: proof of purchase and programmable economic rights (raffle entry, revenue share, rebate eligibility). |
| Neurobits | Testnet engagement points. 1 Neurobit per 1,000 NUSD spent at a CommerceOS. |
| NUSD | The testnet payment unit. Earned through daily check-ins; spent at testnet creator storefronts. |
| Phase 1 / 2 / 3 / 4 | The four-stage launch lifecycle: Community Mining → bonding-curve trading → migration → Uniswap V2. |
| Pre-purchase | Creator's ability to buy up to 90% of supply along the bonding curve before public launch, subject to on-chain vesting. |
| Sniper tax | The tax applied to Phase 2 buys only. Starts at 89%, decays 1%/min to zero. Locked until migration. |
| SUME | The Satsume mainnet platform token. Governance, staking, fee accrual. |
| USDI | The launchpad quote currency. Minted 1:1 (variable) from NUSD on testnet. Transfer-restricted to a whitelist outside platform use. |
