What is ERC-721?

ERC-721 is a token standard on Ethereum that allows developers to create unique, indivisible tokens—each representing ownership of a distinct digital item.

Uniqueness

Genuine one-of-a-kind tokens where each has distinct metadata and attributes, ensuring no two tokens are alike.

Immutability

Once issued, each token’s metadata and ownership history cannot be altered—perfect for collectibles and digital assets.

Transferrability

Seamlessly trade or transfer ownership across wallets and marketplaces, securing provenance of digital goods.

The ERC-721 standard powers NFT platforms where creators and consumers trade unique digital assets—like art, music, virtual land, and more.
