Volatility fee
The fee follows the pool's own recent moves: a moving average of tick changes between swaps sets it between 0.05% and 2%.

Building a v4 hook? This is your market. One pool stacks up to five v4 hooks, and every swap pays each of them.
$V4MExplorer ↗
A v4 pool gets one hook, forever
The hook is fixed in the pool key when the pool opens, and nothing can be added later. So each pool runs one team's code. v4 Marketplace deploys one hook, the hook stack, and it runs up to five v4 hooks written by different authors in the same pool.
Watch live swapsEvery swap pays every v4 hook it passes through
Each hook sets a royalty from 0 to 10 basis points, with 30 for the whole stack. The hook stack takes it from the swap in the pool's own currencies and credits each author on the spot: 80% to the author over seven days, 20% to a burn reserve.
The hook stack
One v4 hook for every v4 Marketplace pool, running up to five v4 hooks in order. Each runs with a hard gas limit. The highest fee wins, a rebate lowers it, any hook can veto, and a hook that fails is skipped and recorded as a failed run.
Explore the hook stackStorefronts
Ship your v4 hook from a storefront with verified source and get paid on every swap that runs it. Its gas, royalty, the pools that stack it, its volume and its failed runs are public.
Explore storefrontsRoyalties
Paid in the currency the swap moves, as claims held on the PoolManager. Authors claim after seven days. A fifth of every royalty funds burnBuy, which anyone can call once an hour.
Explore royaltiesStakes and failed runs
Every listed v4 hook has 10,000 $V4M staked behind it. Three failed runs in a week burn 10% and remove the hook. A proven exploit burns up to all of it, and the author's unvested royalties repay the pool's LPs.
Explore stakesFour house hooks on day one
The house storefront opens with four v4 hooks that hold no funds. They are stacked on the house pools for TSLA, NVDA and QQQ against USDG, and anyone can stack them.
Anti-snipe
A 25% fee the moment a pool opens, falling to nothing over ten minutes. Made for the v4 Marketplace pool a Pons coin opens beside its Pons pool.

Agent rebate
A swap sent by a wallet that holds an ERC-8004 agent identity pays a quarter less fee. Agents find the pools through the hook stack's events.

Weekend gap guard
While the stock market is closed, the fee widens to 1% and swaps that push the price outside 2% of the last close are refused.
Read the formula
A v4 hook for every pool
A stacked hook can do what a standalone hook does on a single swap. Limit orders and the weekend batch come next, as the first hooks allowed to hold funds, with a 50,000 $V4M stake.

Build a v4 hook
Start from the template or any listed hook, compile it on the site, deploy it from your wallet and list it in one flow. The interface has three functions, and agents get an SDK and an MCP server.

We are building an ecosystem of projects around v4 Marketplace, each with its own product and token, all plugged into the same v4 hooks. v4 Builder comes from our team, checked onchain from the wallet that launches its token and the factory that deploys its hooks. Shellbank brings credit for AI agents through its own v4 hook in the catalog. More projects and a community are coming soon.

v4 Builder
Build your own Uniswap v4 hook without writing Solidity. Pick modules, set their numbers, and v4 Builder compiles the hook, runs it on the real PoolManager and deploys it from your wallet, as its own hook or stacked on v4 Marketplace.

Shellbank
Credit for AI agents, built as a Uniswap v4 hook. An agent borrows USDG, every swap it makes repays 0.10% of the USDG side inside the swap, and its limit grows +1 USDG per USDG repaid, up to 1,000.
