How SellFees works, start to finish. Five minutes, tops.
The short version
SellFees launches coins on Robinhood Chain. Each coin is born with a claim: an NFT that collects 90% of the coin's trading fees for as long as the coin trades.
The claim is the coin's income, packaged as something you can hold, move or sell. Keep it and collect the fees. Sell it and the buyer collects them instead. That turns a meme coin into a small business you can actually hand over.
Launching a coin
Fill in a name, a ticker, an optional image and description, choose who gets the claim and what the coin trades against. Then sign one transaction. In that single transaction the launchpad:
- deploys the coin (a standard ERC-20 with a fixed supply of 1,000,000,000),
- opens a Uniswap v3 pool against your pair with a 1% fee tier,
- puts the entire supply in that pool, where it stays forever,
- mints the claim NFT,
- and runs your optional dev buy, before anyone else can trade.
There is no presale, no team allocation and no liquidity to rug: the launchpad owns the only position and has no function to remove it. The coin starts around a $4,000 market cap and its price moves along the pool's curve as people buy and sell.
ETH, stocks or memes
A coin can trade against any ERC-20 on Robinhood Chain. The launch page lists the usual suspects: ETH, the USDG stablecoin, Robinhood stock tokens like NVDA or TSLA, and the chain's bigger meme coins. You can also paste any token address.
The pair decides what buyers pay with, and what most of the fees are paid in. A coin paired with NVDA fills its claim with NVDA stock tokens.
The claim NFT
Claims live in one ERC-721 collection, SellFees Claims. Every coin gets its own numbered claim, and every claim has its own vault inside the contract. The vault is tied to the token id, not to a wallet: when the NFT changes hands, the vault and all future fees change hands with it.
Each claim's metadata shows its coin, pair, type and tagged handle, and the pages on this site show the live vault, fees per day and history.
Where every fee goes
- Every swap in the coin's pool pays a 1% fee, in the token going in: the pair on buys, the coin on sells.
- 90% of it goes to the claim's vault. 10% goes to SellFees. The launcher earns nothing on the side: the claim is the only way to earn from the coin's volume.
- The split is written into the coin when it launches and can't be changed afterwards.
- Claims pay a 1% royalty when they are resold.
Fees work on every trade, whether it goes through this site, the Uniswap app, OpenSea or any aggregator.
Collecting fees
Open your claim and hit Claim fees. The contract sweeps whatever the pool earned since last time, then sends the whole vault to your wallet: the pair side (ETH is unwrapped for you) and the coin side. Collect as often as you like; the vault keeps filling between visits.
Selling a claim
Want out? List the claim at a price in ETH from its page. Whoever buys it gets the vault and every fee from then on, and your project is handed over in one transaction. Nobody has to trust anybody: the fee split lives in the contracts and the claim is a regular NFT.
Claims are also regular NFTs on OpenSea. There is no meaningful floor price, since no two claims earn the same: compare the vault and the fees per day to the asking price. The marketplace's best deal view does exactly that.
Buying works the other way around: find a coin with a community you believe in, buy its claim, and its volume pays you.
Auto buy NFTs
Prefer collectibles to cash? With Auto buy NFTs there is no claim: the claim share of the fees piles up and gets spent on NFTs from Robinhood Chain marketplaces, within the price range you picked at launch. They are sent to you, or to the X account you tagged once its owner logs in. This mode needs an ETH pair.
Contracts & trust
- Three contracts: the launchpad, the claims collection and the coin implementation. None of them can be upgraded.
- Liquidity sits in Uniswap v3 and belongs to the launchpad, which cannot withdraw it.
- The admin can pause new launches and set defaults for future coins. It cannot touch vaults, pools or anyone's claim.
- X logins only produce a signed voucher saying “this wallet belongs to @handle”; the contract checks it before releasing a social claim.
Risks
Meme coins are extremely volatile and most of them go to zero. A claim is only worth the trading its coin attracts. Smart contracts can have bugs. Nothing here is financial advice: only put in what you can afford to lose.
Social claims
Launching a coin about someone? Tag their X account. Their claim is minted into escrow and starts collecting fees right away. When they log in with X on SellFees, we check the account and they pick the claim up in the wallet of their choice, vault included. A tagged claim waits as long as it takes.
