Attaching real value to NFTs

Powered by the Ethereum blockchain, Inscribe lets anyone provably sign and verify handwritten signatures to NFTs.

The Inscribe Protocol

The Inscribe protocol is the source of truth for all inscriptions on the Ethereum blockchain. This allows users to attach and verify metadata on an NFT.

These inscriptions will stay attached to the NFT even if they were transferred. Learn more about the inscribe protocol through our docs.
