User guide: swaps
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.
If you want to sell multiple tokens into a stablecoin in one go, see Batch Sell.

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.
How to swap
Indipendentemente dal fatto che utilizzi l'estensione o l'app mobile di MetaMask, per ricevere i token desiderati bastano solo pochi clic, o tocchi.
On MetaMask Mobile, you can skip the full swap flow by tapping the lightning icon next to any token in search or on its asset details page to buy or sell instantly. Learn more.
- On the main MetaMask screen, click the 'Swap' button.
- Select the token you want to exchange (and from what network, if swapping across chains) (Example: ETH on Ethereum)
- Select the token you want to receive (and to what network, if swapping across chains) (Example: SOL on Solana)
- Enter the amount you want to exchange.
- Review quote and confirm transaction.
Behind the scenes
Swaps is searching across decentralized token exchanges and token swapping protocols to find you the most advantageous exchange rate.
Allo stesso tempo, esegue transazioni di prova per verificare che, se invii una transazione, è probabile che vada a buon fine e, in caso contrario, che quelle opzioni vengano escluse.
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. Il tasso di insuccesso di Swap è molto basso e sono in corso miglioramenti per renderlo quasi inesistente.
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’ > ‘Transactions’, 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.
I nostri articoli dell'assistenza sono solo per MetaMask Swaps. In altre parole, MetaMask fornisce il supporto per gli scambi che avvengono attraverso l'uso del pulsante MetaMask Swaps. Se stai effettuando uno swap direttamente su una piattaforma diversa o su un altro DEX, MetaMask può fornire un orientamento generale o una guida, ma questi non devono essere considerati definitivi; contatta il team di supporto o la community dello exchange o della piattaforma in cui stai effettuando lo swapping per ricevere assistenza.
