ユーザーガイド: スワップ
MetaMask Swaps is a feature available on MetaMask Extension and Mobile that allows you to swap one token for another. It's super convenient and straightforward, reducing the number of steps and third-party smart contracts needed in order to obtain tokens that interest you.
Ethereum • Bitcoin • Linea • Base • Solana • Tron • Polygon • BNB Chain • Arbitrum • OP • Sei • Avalanche • zkSync Era • Monad • MegaETH • HyperEVM
Bridging (transferring assets between networks) can now be done easily through MetaMask Swaps on Extension and Mobile. Just click the 'Swap' button and select the network and token you want to exchange.
When you use MetaMask Swaps, remember that MetaMask is acting as an information aggregator: we pull together quotes so you can find the most advantageous one.
From there, you can decide whether or not to proceed with the transaction with the platform or liquidity provider at hand. MetaMask does not provide the liquidity, execute the trade, or give you any advice whatsoever as to what tokens you should swap.
You can also access real-world assets (RWAs) like tokenized stocks and ETFs directly from MetaMask Swaps if eligible. Simply search for the asset ticker and select the tokenized version, example $GOOGLon (Ondo Tokenized). Learn more about tokenized stocks here.

当社のサポート記事は、MetaMask Swapsについてのみ説明しています。 言い換えれば、MetaMaskはMetaMask Swapsボタンを使用して行われるスワップをサポートしています。 異なるプラットフォームや別のDEXでスワップを行う場合、MetaMaskは一定の一般的な紹介や案内を提供する場合もありますが、これを絶対的なものとはみなさないでください。そのような場合は、スワップを行う交換所やプラットフォームのサポートチームやコミュニティに連絡し、サポートを求めてください。
Behind the scenes
Swaps is searching across decentralized token exchanges and token swapping protocols to find you the most advantageous exchange rate.
同時に、テストトランザクションを実行し、トランザクションを送信した場合、成功する可能性が高いかどうかを確認します。可能性が低い場合、これらのオプションは排除されます。 MetaMask is saving users here from the pain of a failed transaction: with Ethereum Mainnet gas fees and the complexity of token smart contracts, a failed transaction adds a significant financial injury to the insult of an incomprehensible error code. Swapsが失敗する確率は非常に低く、ほぼ失敗しないようにするための改善作業が今も行われています。
Gas fees
Within MetaMask Swaps, you’ll see a value—network fee—which is the transaction fee. Depending on network activity, the gas fee can fluctuate.
To learn more about gas fees, please visit this guide.
What if I don't have enough gas?
Don’t have enough gas to cover your swap? Don't worry – MetaMask now offers gasless swaps, allowing you to fill up on gas and swap your tokens in one transaction. This feature is only available on Ethereum Mainnet, BNB Smart Chain, Linea, and Arbitrum and Base (Extension only).
Smart Transactions enabled
MetaMask versions - version 12.6 or later (Extension) or version 7.43 or higher (Mobile)
'Estimate balance changes’ enabled - this setting is on by default. To find it, go to Settings > Security & privacy, and toggle ‘Estimate balance changes’ on.
Note: Gasless swaps on Base has slightly different prerequisites. For more information, check out 'How to use gasless swaps'.
If your swap meets these prerequisites, we will automatically include gas costs in the quote you receive.
If you're ready to go, click the Swap button!
As with all blockchain transactions, it's not instantaneous, but you should see your tokens in your account soon. If they're uncommon tokens, or for whatever reason they're not showing up in your account, follow our instructions here to add them.
Questions
How are fees calculated?
The fee structure is broken down into:
- Quote rate: the exchange rate for the tokens
- Network fee: gas to execute the swap
- MetaMask fee: 0.875%
What aggregators and bridges do you use?
We source bridging options through aggregators (Li.fi and Socket) and providers (Hop, Celer cBridge, Polygon PoS Bridge, Squid (Axelar), Across, Stargate, Relay, Mayan, and CCTP).
I haven't received my tokens in the time I should have. What should I do?
The time we quote is an estimate, and delays can happen for several reasons, such as a change in network conditions. In most cases, the transfer is just delayed and will still go through automatically. If you've already waited over three hours and your transfer is still in progress, please contact MetaMask Support by clicking the 'Contact Support' button on the home page of this site.
