Своп может быть отменен по разным причинам, хотя частота таких отмен в MetaMask Swaps низкая. Наиболее распространенная причина — нехватка газа для транзакции. Ошибка «нехватка газа» (out of gas) возникает, когда весь газ, выделенный для транзакции, расходуется до завершения свопа. Чтобы предотвратить отмену транзакции по причине «нехватка газа», мы рекомендуем использовать размер сетевой комиссии по умолчанию, предоставляемый MetaMask. Если своп не удается выполнить, часть платы за газ может быть удержана сетью, но актив, который вы хотели обменять в ходе свопа, останется в вашем кошельке MetaMask.

В случае неудачного свопа ваши средства всегда будут в безопасности в вашем кошельке. Если своп завершается неудачно более одного раза, свяжитесь со службой поддержки, чтобы мы могли выяснить причину этого.

MetaMask Swaps automatically aggregate available liquidity from leading Decentralized Exchanges (DEXs) and Professional Market Makers. If you can't find a token, it likely lacks a sufficient amount of liquidity.

Slippage refers to the difference between the expected price of a trade and the price at which the trade is executed. Slippage is most prevalent with larger orders, and during periods of higher volatility. Check out the Xtreamly Slippage Predictor, a MetaMask Snap, for slippage insights and predictions, as well as volatility info.

ERC-20 tokens are deployed with functionality that allows other smart contracts to move tokens. By approving the smart contracts, it now has permission to execute the peer to peer swapping behavior on your behalf. The Spend Limit permission is the total amount of tokens that are able to move when using MetaMask Swaps. By default, we set the allowance to a high value, so you don't have to approve your tokens every time you want to Swap, but you can always configure a lower amount using a Custom Spend Limit.

A service fee of 0.875% is automatically factored into each quote to support ongoing development to make MetaMask even better.
