Guide de l'utilisateur : Swaps

MetaMask Swaps est une fonction de MetaMask qui vous permet de faire exactement cela : effectuer un swap d'un jeton de crypto-monnaie pour un autre (pour plus de détails sur les jetons ERC-20 et la différence entre ceux-ci et les NFT, consultez notre guide d'utilisation). C'est très pratique et simple, et cela réduit considérablement le nombre d'étapes nécessaires, ainsi que l'exposition à des contrats intelligents tiers, afin d'obtenir les jetons qui vous intéressent.
