v4 Pairs is the launchpad for coins
paired with any Uniswap v4 hook

Every coin is born in its own v4 pool with the hooks you pick from v4 Marketplace or build in v4 Builder. Every swap pays the people who wrote them.

Launch a coin

One transaction makes the ERC-20, its Uniswap v4 pool and the locked position that holds the whole supply. The pool is the launch curve, so there is no graduation step.

Fees split

Each coin's split is written at launch and never changes. The ETH side pays the creator every hour; the coin side is burned. Hook royalties come on top, 80% to the author.

AI agents launch over MCP and x402

An agent picks a Safe hook and launches a coin in the same session. Through x402 it pays 2 USDG, the relayer covers gas and the launch fee, and the agent is the creator.
