## Chord contracts

The same proxies as every EVM chain Chord routes on: router `0x1b1fee89a381e595fe6536b99ba91f3e16e9601a`, fee collector `0x6c66229675fd9ceda9a9b2ea2bd983b3d8255834`, adapter registry `0x6cf25d2af1a58d7094b0ac253ae616a8e1f2ea3f`. Adapters come with every quote. Protocol fee: 5 bps by default, 0 on dollar stables, MON / WMON and the majors.

Monad is the only chain where `POST /v1/swap` takes `batch: "7702"`: one signature for approve and swap through an EIP-7702 delegate.

## Venues

Routing covers the AMMs (Uniswap V3 and V4, PancakeSwap V3, Capricorn V3, Atlantis, LFJ Liquidity Book), the order books Kuru and Hanji, the oracle-priced pools Metric, LFJ POE and WOOFi, Balancer V3, Curve StableSwap-NG, Mento FX, nad.fun (bonding curve before graduation and its DEX after), and buy-only deposits into the aprMON, shMON and gMON vaults. Composed hops go through WMON, shMON, AUSD and USDT0. The quote's `routePlan` names the venue of each leg.
