Sudoswap
An NFT AMM protocol — NFT holders create permissionless pools with their own pricing curves (linear, exponential), trading floor NFTs without per-token bid matching.
Sudoswap, launched in 2022, brought AMM mechanics to NFTs. A seller creates a pool with one or more NFTs and a pricing curve (linear or exponential bonding curve); buyers swap ETH into the pool and pull NFTs out at the current curve price.
The protocol was an early enforcer of optional royalties — the move that triggered the broader NFT royalty wars — and proved that AMM-style NFT liquidity was viable for floor items. Sudoswap v2 added more pool types and reduced gas costs.
