How to Use Sushi for a DeFi Swap in 2026

Sushi, also known as SushiSwap, is a decentralized exchange (DEX). It lets you use a crypto wallet to swap supported tokens and, in some markets, contribute tokens to liquidity pools. Unlike a centralized exchange, a DEX does not work by holding your account balance in a company’s custody: you approve transactions from your wallet and remain responsible for your keys.

A swap is an exchange of one token for another, usually through a liquidity pool. The price you receive depends on the pool, the amount traded and current market conditions. A quoted amount is not a promise that the trade will execute at exactly that price; the final result can be affected by price movement and slippage.

Sushi’s available networks, assets and features can change. Treat the market displayed in the current app as the starting point, then verify the network and token contract before you trade. You do not need to buy SUSHI simply to make a basic swap. Its role, if relevant to a particular feature, should be checked separately.

First, decide which token pair and network you want to use. The same token name can exist on multiple blockchains, and a token on one network is not automatically interchangeable with a similarly named token elsewhere. Check the token’s contract address using a trusted source, especially for unfamiliar or newly issued assets.

Before connecting, make sure you have:

• A self-custody wallet you control, with its recovery phrase stored offline.
• The network selected that matches the tokens and market you intend to use.
• Enough of that network’s native token to pay for gas, including if the swap fails.
• A clear idea of the amount you want to trade and the minimum output you would accept.

Open Sushi using an address you have independently verified. Connect only the wallet you intend to trade from, and check that the wallet shows the expected network. A connection lets an app request information and transactions; it is not the same as authorizing every transaction. Never enter a recovery phrase into a website or share it with anyone claiming to provide support.

Use this sequence for a small, straightforward swap:

1. Select the correct network in both your wallet and the Sushi app.
2. Choose the token you are spending and the token you want to receive. Verify both token names and contract addresses.
3. Enter the amount. Review the estimated output, price impact, slippage setting and any route or fee details shown.
4. If the wallet asks for token approval, check which token and spending allowance the approval covers. Approve only what is needed for the intended trade.
5. Review the swap transaction in your wallet, including the destination, network and estimated gas, then sign only if it matches your intent.
6. Wait for confirmation and check the received token balance on the correct network.

For a first transaction, consider testing with a small amount you can afford to lose. A tiny test still incurs gas and may be uneconomical, so compare that cost with the risk it reduces. If the quote changes materially before you sign, pause and inspect the updated terms instead of approving automatically.

A Sushi trade can involve more than one cost. The pool or trading fee is reflected in the trade terms; network gas is paid separately to process transactions. Some swaps may also show routing costs or incur price impact, meaning the trade itself moves the pool price. These figures depend on the network, market and trade size, so do not assume one fee estimate applies across Sushi.

Check the full quote before signing. Compare the amount you spend with the minimum amount you will receive, and make sure the slippage tolerance is not wider than you can accept. A wider tolerance can help a trade execute during volatility, but it can also allow a worse fill. A narrow tolerance may cause a transaction to fail if the price changes before execution.

Gas can be spent even when a transaction fails or is replaced, depending on what happened on-chain. If you need to bridge assets to reach a supported network, that is a separate transaction with separate fees and risks. Do not treat a low displayed pool fee as the full cost of using the service.

Liquidity providers deposit tokens into a pool so traders can swap between them. In return, a pool may distribute trading fees according to its rules. The return is not fixed or guaranteed, and providing liquidity is a different decision from making a one-off swap.

A key risk is impermanent loss: as the relative prices of the tokens change, the value of your pool position can be lower than if you had simply held the tokens. Fees may or may not offset that difference. You also face the risk of a token losing value, a pool having insufficient liquidity when you want to withdraw, or a smart-contract issue affecting deposited funds.

Before supplying tokens, review the exact pool, its assets, fee terms, liquidity and any special mechanics. Confirm whether the position requires one token or a pair, how deposits and withdrawals work, and whether you may need to claim anything separately. Do not choose a pool based only on a displayed yield or recent activity. If you cannot explain how the pool works and what could reduce your return, stick to learning with no deposit.

A wallet-based DEX still depends on software, smart contracts, token issuers and the network you use. A transaction can be irreversible, and a legitimate-looking token can still be a scam or have restrictive transfer rules. Use a deliberate security check before every signature:

• Confirm the app address and network independently.
• Verify token contract addresses; do not rely on a logo or ticker alone.
• Read wallet prompts, including approvals, amounts, contract destinations and gas.
• Reject unexpected requests to sign messages or grant broad token allowances.
• Keep your recovery phrase offline and never share it with a support account.
• Avoid trading an amount you cannot afford to lose.

A token approval can let a contract spend the approved token amount from your wallet. It is not the same as a swap, so read the approval separately. If you do not recognize the contract or cannot tell what the wallet is asking you to authorize, cancel and investigate. A successful connection or a familiar interface is not proof that a token, pool or transaction is safe.

Most avoidable losses start with rushing: selecting a token by ticker alone, using the wrong network, accepting a poor quote or signing a request without reading it. Slow down when a trade is unusually urgent, a token has little liquidity, or an unexpected prompt appears.

Common mistakes to avoid:

• Sending funds to a token or network that the recipient wallet cannot access.
• Confusing a token’s name with its verified contract address.
• Setting slippage so high that you accept a substantially worse outcome.
• Forgetting to keep gas for the swap, approval or later transactions.
• Assuming a failed trade means no fee was charged.
• Treating a displayed pool return as guaranteed income.
• Repeating a pending transaction without checking its status.

After you sign, keep the transaction record and confirm whether it succeeded before taking another action. If you sent assets to the wrong network or address, do not assume support can reverse it; recovery may be impossible. Avoid anyone who asks for your recovery phrase or a payment to “unlock” a transaction.

After the wallet reports a confirmation, verify the transaction status and token balance on the same network you used. If the expected token does not appear, check whether the transaction completed and whether the wallet needs the correct network or token added for display. Do not make another swap until you understand the first transaction’s result.

If the transaction is pending, the wallet may offer a network-specific option to speed it up or replace it, but those actions can involve another fee. Read the wallet’s explanation and avoid signing an unfamiliar replacement request. A failed transaction can still cost gas because network validators may have processed the attempt even though the swap did not complete.

For a completed trade, compare the actual output with the minimum shown before signing. Save the transaction details for your records, particularly if you need to track cost basis or report taxable activity under local rules. Tax treatment varies by jurisdiction, so check the rules that apply where you live. For future trades, use what you learned to reassess the network, token, quote and amount rather than assuming the next transaction will have the same costs.
