This functionality makes it a valuable tool for users engaged in various DeFi activities, including trading, staking, and participating in initial coin offerings (ICOs).

Supported Tokens on MetaMask

1. Ethereum (ETH) Ethereum is the native cryptocurrency of the Ethereum network and is supported by MetaMask. As the primary asset on the Ethereum blockchain, ETH is used for transactions, smart contract execution, and as gas to pay for network fees.

   • USDT (Tether)
   • LINK (Chainlink)
   • UNI (Uniswap)
   • DAI (Dai Stablecoin)
   • MKR (Maker)
   • BAT (Basic Attention Token) These tokens are widely used in various DeFi applications, from trading to lending and borrowing.

3. ERC-721 Tokens ERC-721 tokens are non-fungible tokens (NFTs) that represent unique assets on the Ethereum blockchain. MetaMask supports ERC-721 tokens, which include various NFTs used for digital art, collectibles, and gaming. Some popular NFTs include:

   • CryptoPunks
   • Bored Ape Yacht Club
   • Decentraland
