MetaMask 스왑의 실패율은 매우 낮지만, 다양한 원인으로 인해 스왑이 실패할 수 있습니다. 가장 일반적인 원인은 트랜잭션 중 할당된 가스가 모두 소모되어 발생하는 '가스 부족' 오류입니다. ‘가스 부족’ 오류는 스왑이 완료되기 전에 트랜잭션에 할당된 모든 가스가 사용되었을 때 발생합니다. 이러한 '가스 부족' 트랜잭션 실패를 방지하기 위해, MetaMask가 제공하는 기본 네트워크 수수료 설정을 사용하는 것을 권장합니다. 스왑이 실패하더라도, 일부 가스비는 네트워크에 의해 소모될 수 있지만, 스왑하려던 자산은 여전히 MetaMask 지갑에 안전하게 남아 있게 됩니다.

스왑이 실패하더라도 자금은 항상 지갑에 안전하게 보관됩니다. 스왑이 여러 번 실패할 경우, 근본적인 원인을 조사할 수 있도록 지원팀에 문의해 주세요.

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.
