Sudoswap is a minimal, gas-efficient automated market maker (AMM) protocol for NFTs that facilitates NFT-to-token swaps using customizable bonding curves. It supports ERC-721 and ERC-1155 NFTs alongside ETH and ERC-20 tokens. Liquidity providers can create single-sided buy/sell pools or dual-sided trade pools to earn fees. Developers interact with the protocol through smart contracts (LSSVMPair, VeryFastRouter, bonding curve contracts) and off-chain indexing services such as The Graph subgraph and the Defined/Codex data API. Sudoswap v2 is deployed on Ethereum mainnet, Arbitrum, Base, Berachain, Sanko, and other EVM-compatible networks.
