Sushi — FAQ

Sushi is a decentralized exchange protocol accessible at sushi.com that allows users to swap tokens directly from their own wallets using automated market maker smart contracts. There is no central order book; instead, trades are executed against liquidity pools funded by other users who earn fees in return. The process is non-custodial, meaning the platform never holds your funds.

The standard swap fee is 0.3% per transaction, of which 0.25% goes to liquidity providers and 0.05% flows into the protocol treasury. Certain stablecoin pools operate at lower fee tiers of 0.05% or 0.01%. There are no account fees, subscription charges, or hidden withdrawal costs, making this exchange one of the more cost-transparent options in DeFi.

The protocol has been audited by multiple reputable security firms and operates a public bug bounty program to encourage responsible vulnerability disclosure. Because the exchange is non-custodial, users retain control of their private keys at all times. As with any DeFi protocol, users should exercise caution, verify contract addresses, and use hardware wallets for larger holdings.

In 2026, the platform supports more than 30 blockchain networks including Ethereum, Arbitrum, Optimism, Polygon, BNB Chain, Avalanche, Fantom, and several emerging Layer 2 solutions. This broad multi-chain presence allows traders to access liquidity wherever it is most favorable without switching between different exchange interfaces.

No account registration or identity verification is required. Users simply connect a compatible Web3 wallet — such as MetaMask, WalletConnect, or Coinbase Wallet — to sushi.com and can begin trading immediately. This permissionless access is one of the defining advantages of using a decentralized exchange over a traditional centralized platform.

The SUSHI token serves as the governance token for the protocol, allowing holders to vote on proposals that shape the exchange's direction, fee parameters, and treasury spending. Holders can also stake the token to earn a portion of protocol revenue. It is traded on the platform itself as well as on numerous centralized exchanges, giving it broad market accessibility.

Unlike centralized exchanges, this protocol does not require KYC, never holds user funds, and operates transparently via open-source smart contracts. Trade execution happens on-chain, eliminating the risk of exchange insolvency or withdrawal freezes. The trade-off is that users bear responsibility for their own wallet security, and gas fees apply on networks like Ethereum, though Layer 2 options make costs significantly lower.
