Each token is identical in value & type, similar to how one dollar is equal to another13.

Functions: ERC-20 tokens allow for transferring, checking balances, and approving transactions19.

Each token represents a distinct asset24.

Features: ERC-721 tokens are indivisible and represent ownership of a singular item.
