Tokenize

Mint a document as an NFT, with its hash on-chain.

A narrow command-line tool that mints supported files as NFTs through the E3D wallet mint flow, proving that exact file content existed, unaltered, at a wallet address at a point in time.

What it does

  • One NFT per file, plus a group NFT when you mint several together.
  • Embeds a SHA-256 hash of the original file bytes.

It does not prove legal ownership or title, the truth of a document's claims, authorship, or the identity of the wallet holder.
