v4-nativedeflationaryimmutable
entr0py is the first ERC-20 where scarcity is engineered into the market itself. A Uniswap V4 hook intercepts every swap and burns supply on the way through. The longer the market trades, the smaller the supply gets. There is no team holding bags, no faucet, no emission schedule, no admin to flip it off.
And the scarcity isn't neutral — it's asymmetric. Buys contribute a small 1% burn so accumulation isn't punished. Sells contribute 5× that. Every exit pays the cost of leaving by making everyone still holding more rare. Volatility, panic, and profit-taking all compound the supply collapse instead of diluting holders. Selling is the scarcity mechanism. The fees go to address(0) and are gone forever.
Buy fee
1.00%
Of the entr0py you receive, 1% is diverted to
0x0…0 by the hook's afterSwap callback before the tokens reach your wallet.Sell fee
5.00%
Of the entr0py you sell, 5% is held by the hook in
beforeSwap, used to buy entr0py back from the pool, and burned. Sells fund their own burn.01
Trade enters the V4 pool
A user calls swap() on the Uniswap V4 PoolManager. The pool is registered with the entr0py hook at deploy time and routes every swap through it.
02
Hook intercepts via beforeSwap / afterSwap
The hook reads the swap direction. If buying entr0py → 100 bps fee. If selling entr0py → 500 bps fee. The fee is taken in entr0py, in-flight, before settlement.
03
Fee → buyback (sells only) → burn
Buy fees are burned directly. Sell fees are converted to entr0py via an internal pool query and then burned. Either way, the destination is address(0) and the supply count drops.
04
Supply only decreases
There is no mint function on the token, no rebase, no emission schedule. The contract has no owner — there is nothing to call. The number on the homepage only goes one direction.
Why this is different
- Asymmetry is the point. Holding is cheap, exiting is expensive, and every exit makes everyone else's share larger.
