ERC-20
The Ethereum standard for fungible tokens like stablecoins, complementing the ERC-721 NFT standard.
- glossary
ERC-20 is the Ethereum Improvement Proposal that defines a standard interface for fungible tokens — every unit is identical and interchangeable, just like dollars in a bank account. Any contract implementing ERC-20's transfer, approve, and allowance functions is automatically compatible with wallets, exchanges, and DeFi protocols without custom integration. Stablecoins like USDC and USDT are ERC-20 tokens, as are most governance and utility tokens. ERC-20 contrasts sharply with ERC-721: an ERC-721 token is non-fungible — each one has a unique ID representing a distinct asset, like a specific domain name.

Victor Zhou is a technology founder and standards editor focused on digital identity and trust. He founded Namefi, edits Ethereum Improvement Proposals, and previously led smart-contract architecture work at Google Labs.
His work sits at the intersection of naming, ownership, and the systems people use to establish identity online. That perspective makes him especially interested in the way names move between personal meaning, public recognition, and digital infrastructure.
For Namefi, Victor edits and writes about domains as durable digital identity: how names become ownable onchain assets, how tokenization changes custody and trust, and what naming can learn from the systems people use to establish identity online.
