How it works

Every pool is a set of rules you can see

  1. 1Pick your blocks

    Launch guard, dump damper, auto burn, surge fee, or reviewed community blocks. Up to five per pool, each with its own settings.

  2. 2Preview every fee

    The builder asks the real block contracts what each trade would pay and draws the curve before anything touches the chain.

  3. 3Launch, or open a market

    Mint a new token into a locked pool, or put your rules on a token that already exists. The rules freeze the moment it opens.

The builder

A workbench for your hook.

Compose, preview, launch and trade from one place. Every number on screen comes straight from the chain.

A pool page: live fees, the pool's frozen rules, and panels to trade and add liquidity.
Designed for trust

Your rules, enforced by code. Not by us.

  • Fees have a ceiling

    Whatever blocks ask for, no trade pays more than 50% in a pool's first 15 minutes, or 10% after.

  • Frozen at launch

    A pool's blocks and settings lock the moment it opens. Nobody can change them, including us.

  • Every rule is readable

    Blocks are open contracts with their settings on chain, and the hook reader explains any hook on Arc.

The kernel

One hook runs every pool, and it keeps every block in check.

Questions

Answers before you build.

  • A Uniswap v4 hook is a contract a pool calls on every trade. It can change the fee, refuse a trade or take a cut. Here one kernel hook runs every pool and asks that pool's blocks what to do.

  • No. Pick blocks, set their numbers, and the builder draws the fee curve before you launch. Developers can write new blocks and submit them to the catalog.

  • The whole supply goes into a Uniswap v4 pool against USDC and stays locked there. Nobody can pull it out: not you, not the platform.

  • No. A pool's blocks and settings freeze when it opens. Retiring a block from the catalog only stops new pools from choosing it.

  • Blocks are read only and run on a fixed gas budget. If one fails it is skipped. Whatever blocks ask for, the kernel caps fees at 50% for the first 15 minutes and 10% after.

  • Yes. Open a market for any Arc token at a starting price you choose; liquidity providers earn its fees. The launch guard is for new tokens only.

  • An approved block earns a royalty: a share of the protocol's fee from every launch that uses it. It never comes out of the creator's share.

  • Not yet. The contracts are tested, including on a copy of Arc mainnet, but they are unaudited. Use only what you can afford to lose.
