What is sudoswap?
sudoswap is an on-chain automated market maker protocol and decentralized marketplace designed for trading non-fungible tokens. Instead of matching buyers and sellers through traditional off-chain order books, the platform lets users trade instantly against liquidity pools driven by customizable mathematical bonding curves.
How the AMM mechanics work
Trading on sudoswap works through non-custodial smart contracts across Ethereum, Arbitrum, Base, and Berachain. Liquidity providers deposit NFTs alongside ETH or ERC-20 tokens into single-sided or two-sided pools. Each pool operates on a pricing curve, adjusting buy and sell prices automatically as inventory changes. Version 2 expanded pool functionality to support ERC-1155 multi-token assets, fee streaming, conditional orders, and on-chain creator royalties.
Trading costs and platform fees
The protocol levies a 0.5% platform trading fee on transactions. Depending on pool configuration and collection settings, transactions on V2 pools may also route creator royalties directly on-chain. Liquidity providers determine pool spreads to earn fees on every trade routed through their liquidity curves, while users pay standard network gas fees on the respective execution chain.
Protocol track record and deployment
The sudoswap AMM launched in May 2022 on Ethereum, opening its primary NFT marketplace interface in July 2022. In September 2022, the protocol introduced its SUDO governance token with an initial supply of 60 million, distributing 41.9% to holders of XMON. The protocol expanded across Arbitrum, Base, and Berachain, accumulating $4.85M in total fees and $4.42M in protocol revenue by October 2026. As of October 2026, the marketplace maintains about $1.03M in total value locked, with $1.02M held on Ethereum. Protocol smart contract audits for V2 are published publicly on GitHub.
Risks and liquidity trade-offs
Liquidity on sudoswap remains concentrated in select collections. Thin liquidity pools can result in steep price slippage along the bonding curve during large volume swaps. Users also face smart contract exposure across multi-chain deployments, and illiquid NFT markets can leave pool depositors holding depreciating inventory if collection floor prices drop sharply.

Good
Sudoswap offers instant NFT liquidity and low trading fees via automated bonding curves, but thin protocol volume and reduced creator incentives limit broad collection diversity.
Sudoswap is an on-chain automated market maker protocol that shifts NFT trading from traditional off-chain order books to automated bonding curves. Launched in May 2022 on Ethereum, it enables liquidity providers to deposit NFTs and ERC-20 tokens or ETH into pools that automatically adjust prices after each trade. Rather than waiting for individual buyers, traders can instantly swap NFTs against pooled capital.
The protocol’s clear advantage lies in pricing efficiency and transaction costs. Sudoswap charges a low baseline platform trading fee of 0.5%, delivering substantial savings compared to legacy marketplaces that charge 2% to 2.5%. Its automated pools allow collectors and market makers to earn swap fees while setting customized linear or exponential pricing curves. Deployments across Ethereum, Arbitrum, Base, and Berachain give traders multiple options to avoid high gas fees.
However, the platform has faced structural challenges. Sudoswap V1 excluded creator royalties by default, creating friction with creators before Sudoswap V2 added on-chain royalty support and ERC-1155 compatibility. Protocol TVL stood at approximately $1.03M in October 2026, down sharply from historical highs as overall NFT trading activity cooled. Low liquidity means larger bulk swaps can suffer from rapid price slippage along the bonding curves.
Governance operates through the SUDO token, which launched via an airdrop in 2022. Security-conscious users can review open audit reports for V2 contracts on GitHub. Sudoswap suits programmatic traders, quantitative market makers, and collectors who need instant exits for floor-level assets. Those seeking bespoke 1-of-1 digital art, rare curated drops, or deep order-book listings should choose broader platforms like OpenSea.
