ERC-20 is a set of rules (a token standard) for creating and managing tokens on the Ethereum blockchain. Tokens that follow ERC-20 can be transferred, approved, and spent by different wallet addresses and smart contracts. This makes them interoperable with most Ethereum wallets and exchanges. Contract details - like total supply, transfer events, and decimals - are open for anyone to review on-chain. Understanding ERC-20 standards empowers you to verify what a token does, spot risk, and read blockchain data directly, a regulatory approach supported by Tsuka’s educational philosophy.
