uniFund is a self-funding token on Uniswap v4. Every trade — buy or sell — pays a 3% ETH tax, and 10% of the pool's liquidity bleeds out every 8 hours, forever, with the removed tokens burned. All of that ETH pools into a reflection vault that holders claim as ETH, weighted by how long they've held. The model below projects how the rewards pool and your personal cut grow as volume and time accumulate — hover the chart to read any point.
uniFund — Whitepaper
1. Overview
uniFund (ticker uFund) is a token on Uniswap v4 designed to pay its holders in ETH. It is paired against native ETH in a v4 pool, and a custom hook attached to that pool runs all of its logic automatically whenever someone trades. The idea is simple: trading the token continuously feeds an ETH reward vault, and anyone who holds the token can claim a share of that ETH. At launch, 90 percent of the supply is seeded as liquidity and 10 percent is held by the deployer; the starting price is set so 2 percent of the supply is worth 0.25 ETH; and a 2 percent max-wallet limit applies to buys for the first 20 blocks, then lifts automatically.
2. How the vault is funded
Two things fill the reward vault. First, every trade pays a 3 percent tax — on both buys and sells — that is taken directly in ETH and set aside for holders, rather than being sold off into the pool. Second, the pool's own liquidity slowly bleeds out over time: every 8 hours, 10 percent of the liquidity is removed. The ETH portion of what gets removed goes into the same reward vault, and the token portion is burned and gone forever. This bleed never stops; it keeps going for as long as the pool exists.
3. The liquidity bleed
The liquidity removal does not happen on a timer of its own. It happens lazily, meaning it is triggered by trading. The hook checks how much time has passed since the last removal, and when at least 15 minutes have elapsed it removes the matching slice on the next swap. If nobody trades for a while, nothing is removed until the next trade comes in, at which point the pool catches up on what it owed for the time that passed.
4. Rewards and claiming
Rewards are shared by time-weighted balance, measured against the circulating supply — that is, the tokens actually held by holders, excluding the pool's liquidity and the burned tokens. This matters: if you hold 2 percent of the total supply but most of the supply is still sitting in the liquidity pool, your share of the rewards is much larger than 2 percent. And because every bleed burns tokens and shrinks that circulating base, each remaining holder's share keeps rising over time. You can claim your ETH at any time, and your pending rewards are also settled automatically whenever you buy or sell through the uniFund router. There is no price floor and no cap on the bleed; the tax, the 10 percent per 8 hour removal, and the burning of removed tokens all run permanently, which means the pool thins over time and trades carry more price impact as the protocol ages. This is a reference implementation and is not audited, and nothing here is financial advice.
