What is a token approval in Avalanche C-Chain?

A token approval grants a smart contract permission to transfer ERC-20 tokens from your wallet on your behalf, commonly used by DEXes (Trader Joe) and DeFi protocols.

Why should I revoke unused token allowances?

Revoking unneeded allowances protects your wallet funds in the event that a previously approved smart contract or protocol gets compromised.
