Knowledge Card: Token Approvals
Before swapping ERC-20 tokens on a decentralized exchange, you generally need to sign an approval transaction first, allowing the other contract to transfer those tokens from your wallet.
Before signing, check the token, amount, and contract address being approved. If anything is unclear, don’t rush to sign.
Price at the end: $ETH quoted at 2417.88, 24h -0.19%.
