SushiSwap, now simply called Sushi, is one of the best-known names in decentralized finance (DeFi). If you are new to crypto and wondering what it does, how to swap tokens on it, or whether it is safe, this guide covers the basics in plain language. You will learn how SushiSwap works, what the SUSHI token is for, how to make a swap step by step, and the risks to understand before you connect a wallet.
Key Takeaways
- SushiSwap is a decentralized exchange (DEX) where you swap tokens directly from your own wallet, without handing funds to a company.
- It launched in 2020 as a fork of Uniswap’s code and has since expanded to more than 40 blockchains, according to project and third-party descriptions.
- Trades happen against liquidity pools, and liquidity providers earn a share of the trading fees.
- The SUSHI token is used for governance, and staking it as xSUSHI has been linked to a share of protocol fees.
- Features change, and some older products have been described as deprecated, so always check the official site for what is currently available.
- DeFi carries real risks, including smart contract bugs, impermanent loss, slippage, and phishing, so start small and verify every link.
What Is SushiSwap?
SushiSwap is a decentralized exchange built on smart contracts. Instead of an order book run by a company, it uses an automated market maker (AMM). Users deposit pairs of tokens into liquidity pools, and anyone can swap between those tokens at a price calculated by a formula. The people who supply the tokens, called liquidity providers, earn a portion of the fees from each trade.
Because it is non-custodial, you keep control of your tokens in your own wallet until the moment you approve a swap. There is no account to sign up for, but that also means there is no customer service desk that can reverse a mistake.
A Short History of SushiSwap
SushiSwap launched in August 2020 as a fork of Uniswap’s open-source code. It gained attention by rewarding liquidity providers with its own SUSHI token and by putting the project in the hands of a community rather than a single owner. Its early days were turbulent, including a public dispute over its anonymous founder and a development fund, and leadership later passed to other contributors.
Over time the project grew beyond a simple exchange. It added a routing engine, cross-chain swaps, and tools for liquidity providers, and it deployed to many networks. It now competes with larger exchanges, so its focus has shifted toward routing, aggregation, and partnerships with specific networks.
How SushiSwap Works
Liquidity pools and swaps
When you swap one token for another, you are trading against a pool that holds both tokens. The pool’s formula adjusts the price as the balance changes. A bigger trade moves the price more, which is why trading in thin pools can be costly.
Liquidity providers
People who deposit tokens into a pool receive a share of the trading fees. In return they take on risks, including impermanent loss, which happens when the prices of the two tokens move apart and your share is worth less than if you had simply held them.
Pool types
Sushi offers classic pools, where funds are spread across all prices, and concentrated-liquidity pools similar to Uniswap v3, where providers choose a price range. Concentrated pools can earn more fees for the same capital, but they need more attention because your funds can fall out of range.
RouteProcessor
Sushi uses a routing engine called RouteProcessor to search its own pools and other liquidity sources for a good price. Current materials describe versions 6 and 7. This lets Sushi work as an aggregator as well as an exchange.
SushiXSwap
SushiXSwap is the feature for swapping tokens across different blockchains in one flow. It relies on outside bridging and messaging systems, so the safety of a cross-chain swap also depends on those systems.
What Is the SUSHI Token?
SUSHI is the project’s governance token. Holders can vote on proposals that affect the protocol. Descriptions of the project also say that staking SUSHI as xSUSHI can entitle holders to a share of protocol fees. Rules and fee shares can change through governance, so read the current documentation instead of relying on older articles. Nothing here is a recommendation to buy the token.
Supported Networks
Sushi describes itself as operating on more than 40 chains, and it has been named as the core DEX on the Katana network. Supported networks change over time, and not every feature is available on every chain, so confirm the list on the official site.
How to Swap Tokens on SushiSwap: Step by Step
- Install and secure a wallet. Use a reputable wallet and write your recovery phrase down offline. Never share it with anyone.
- Fund the wallet. Add the network’s native coin for fees, such as ETH on Ethereum, plus the token you want to swap.
- Open the official site. Type the address yourself or use a trusted bookmark. Avoid links from ads, direct messages, and unknown posts.
- Connect your wallet. Approve the connection and check that you are on the right network.
- Choose your tokens. Select the token you are paying with and the token you want to receive. Confirm the token contract addresses, since fake tokens often copy real names.
- Enter the amount and review the quote. Check the price impact, network fee, and the minimum amount you will receive.
- Set your slippage tolerance. Keep it as low as practical, because a high setting can lead to a worse price.
- Approve and confirm. You may need two transactions: one to approve the token and one to swap. Limit the approval to the amount you need if your wallet allows it.
- Check the result. Look at your wallet and the transaction on a block explorer to confirm that the swap completed.
Start with a small test amount the first time.
Fees You Should Expect
- Trading fee: A small percentage of each swap, paid to liquidity providers and sometimes shared with the protocol.
- Network (gas) fee: Paid to the blockchain and changes with congestion. It is often much lower on layer 2 networks than on Ethereum’s main network.
- Price impact and slippage: Not a fee, but they can cost you more than the fees if you trade in a thin pool.
- Bridge costs: Cross-chain swaps may add extra charges from the bridging systems involved.
Fees and rates differ by pool and network, so read the numbers on the swap screen before you confirm.
How Liquidity Providing Works
Providing liquidity means depositing equal values of two tokens into a pool. You receive a position that tracks your share, and you earn part of the fees. Before you try it, ask yourself:
- Do I understand impermanent loss?
- Is the pool deep enough, and is the trading volume high enough to earn meaningful fees?
- Am I comfortable with the smart contract risk of the pool?
- How easily can I withdraw?
Beginners may prefer to learn by swapping first and only later try providing liquidity with a small amount.
Is SushiSwap Safe?
No DeFi protocol is risk-free, and SushiSwap is no exception. The contracts have been audited, and the project has existed for years, but past audits do not guarantee future safety. In 2023, a reported exploit involving an older router contract affected users who had approved it, which shows why reviewing and revoking old approvals matters.
The biggest dangers for most users are not flaws in Sushi itself but mistakes and scams around it, including fake websites, impersonator accounts, and malicious token approvals.
Risks to Understand
| Risk | What it means | How to reduce it |
|---|---|---|
| Smart contract risk | Bugs can lead to loss of funds | Use small amounts and well-established pools |
| Impermanent loss | Liquidity can be worth less than holding | Learn how it works before providing liquidity |
| Slippage | You receive less than expected | Check price impact and set a low tolerance |
| Bridge risk | Cross-chain swaps depend on extra systems | Avoid large first-time cross-chain transfers |
| Phishing | Fake sites steal wallet access | Use official links and bookmarks |
| Token approvals | Contracts can spend your tokens | Limit approvals and revoke old ones |
| Project risk | Strategy, governance, and token value can change | Follow official updates and avoid overexposure |
SushiSwap vs Other Exchanges
- Compared with centralized exchanges: SushiSwap lets you keep control of your funds and trade tokens that centralized platforms may not list, but it offers no account recovery and no customer support for mistakes.
- Compared with other DEXs: Sushi competes with larger names such as Uniswap and others. Differences include supported networks, routing, features, and token design. The best choice depends on the token and the network you need, so compare quotes before you trade.
Common Mistakes to Avoid
- Using a link from a search ad, social post, or direct message instead of the official site.
- Buying a token with the same name as a real one but a different contract address.
- Setting slippage very high to force a trade through.
- Giving unlimited token approvals and never reviewing them.
- Forgetting to hold the native coin needed to pay network fees.
- Chasing very high yields without understanding where they come from.
- Sending a large amount across chains on the first attempt.
