How Defib works
Defib is an NFT + token launchpad on Ethereum, built on Uniswap V4. Every coin goes straight into a V4 pool — no bonding curve — with its liquidity locked forever, ships with a linked 4,222-piece NFT collection, and pairs with ETH, USDC or a tokenized stock. All of it runs through one Defib hook on the pool.
Launch
One transaction deploys your coin and its NFT collection, creates its Uniswap V4 pool against the pair you pick — ETH, USDC or a tokenized stock (xStocks such as TSLAx, NVDAx) — and puts the whole supply in as one-sided liquidity — no creator allocation; a creator who wants coins makes a first buy at the same price as everyone. Every coin opens at the same $3,700 market cap: the launchpad works out what that is in the pair (ETH from the Chainlink ETH/USD price, 3,700 USDC, or the stock's price), so nobody can pick another start. You don't need any pair tokens for liquidity; an optional first buy is made with no fee. The position belongs to the launchpad, which has no way to remove it, so the liquidity is locked forever.
The coin
A plain ERC-20 — no transfer tax inside the token, no mint, no blacklist, no pause — so it works like any normal token in wallets, bridges and exchanges. The fees, the burn and the NFT all live in the pool’s hook.
The NFT
Each coin has an ERC-721 collection capped at 4,222. Every buy above a small minimum (0.001 ETH on ETH pairs, 1 USDC on USDC pairs) mints one NFT to the buyer until the cap is reached; a failed mint never blocks a trade. Buying through the Defib site always credits your wallet; other routers credit the wallet that sent the transaction.
The fee
You pick a buy and a sell fee, taken by the hook on every swap in the coin's pair (ETH, USDC or the stock). Public coins are capped at 5%. On top of that, 1% of the coins in every sell is burned. Wallet-to-wallet transfers are never charged. The pool also has a 0.3% Uniswap LP fee, which goes to the locked position.
Fee streams
The platform takes 20% of the fee today; the rest is split across the streams you turn on, paid in the pair: creator, reflections to holders, buyback & burn, a fixed address, and — on ETH pairs — stakers or a social vault for a GitHub user or X handle. A standard coin with no streams sends the whole creator side to the creator. ETH fees pay out on their own; USDC and stock fees pay out when anyone presses “Pay out now” and are then claimed in that token. If a payout can’t be delivered, it’s kept for that wallet to claim — it never blocks a trade.
NFT Burn mode
A creator can launch in NFT Burn mode instead: the creator gets nothing, and the whole creator share goes to the Defib burn vault as ETH (USDC or stock fees are sold to ETH first). When a coin has enough, the vault buys a famous NFT — a CryptoPunk, a Milady, or another allowed collection — and in the same transaction sends it to 0x…dEaD. The vault can only spend a coin’s ETH on that coin’s burns, only on allowed collections up to a max price, and no one can withdraw it.
Reflections & buyback
Reflections accrue to every holder in proportion to their balance and are claimed any time, in the pair token. The buyback stream builds a reserve the creator spends on market buys that are burned (anyone can once the coin is renounced). LP fees from the locked position can be collected by anyone: the pair side goes through the same streams and the coin side is burned.
Platform settings
The platform can change these at any time, and every change is an on-chain event shown on the coin page: its share of the fees (default 20%, up to 90% — for all coins or one coin), buyback-burn on or off (while off, that share goes to the creator), the sell burn (0–1%), and the address the platform share is paid to. It can never raise a coin’s buy/sell fee, touch the pool, or take what’s already been paid out.
Defib AI
An OpenAI-compatible API (base URL defib.sh/api/v1) for hundreds of models, paid in ETH. Sign in with your wallet, create an API key, deposit ETH into the credit vault on-chain and pay per request. Usage is metered off-chain and settled on-chain every few minutes — only what you used, never more than your balance. Withdraw the rest any time: request it, and it opens one hour later. Your prompts go to the model provider; your balance and keys stay with Defib.
$DEFIB holder credits
Fees that flow into the AI vault ($DEFIB trading fees) are split on-chain: a share set by the platform (default 50%) becomes AI credits for $DEFIB holders. Every hour that share is divided pro-rata among wallets holding at least the minimum (default 1,000 $DEFIB) and lands on their Defib AI account; requests spend credits before ETH. Credits pay for API usage only — they can’t be withdrawn or transferred and aren’t a return on holding the token.
Approval
Every launch is reviewed first (up to 24h). You sign a free message with the full launch details; the platform signs an approval that also carries the coin’s fee cap, so a coin can never be set above what was approved. Approve once, launch once.
Safety
The creator can only lower the fees or hand the coin over / renounce — never raise a fee past its launch cap, never touch the pool. Only the Defib launchpad can create pools with the Defib hook. Tokenized stocks are issued by a third party that can pause or restrict their transfers. The contracts are unaudited and verifiable on the explorer.
