● ● ●ERC-7407TOKEN STANDARD

A community-proposed Ethereum standard* that fuses fungible ERC-20 balances with an append-only revision stream for encrypted off-chain intellectual property. One contract. Distribution, licensing, and verifiable provenance on Base.

01

Revision ledger

An append-only, hash-linked chain of IP commitments embedded directly in the token contract. Every revision is immutable, time-ordered, and verifiable back to genesis.

02

Burn-to-license

Tokens are irrevocably destroyed on access. Redemption is consumptive, not permissive — eliminating double-licensing inherent in balance-check access models.

03

Off-chain secrecy

The contract stores only commitments, pointers, and redemption records. Decryption keys, plaintext, and encryption parameters never appear on-chain or in calldata.

04

One contract

A single address serves as fungible rights token, continuity ledger, rights manifest registry, and burn-gated entitlement surface. No external registries required.
