Capacidades

Sovereign identity

Smart Contract Standard Atributos

Origins

Proposed by Fabian Vogelsteller (also ERC-20 author) as a foundation for self-sovereign identity on Ethereum; influenced by early W3C DID discussions and the need for a universal identity contract capable of holding keys, claims, and execution rights.

Data Formats

ABI-encoded key-value pairs (bytes32 keys, bytes values); LSP (LUKSO Standard Proposals) JSON metadata schemas for profile data; ERC-165 interface detection

Terms

CC0

Funds

Unknown

Based On

ERC-20 (Vogelsteller's prior work); W3C DID concepts; ERC-735 (claim holder, associated standard)

Permissions

Permissionless deployment; key-based execution rights; operator/controller patterns

Development Tools

erc725.js library, LUKSO tools, OpenZeppelin adaptations, ERC725Alliance reference implementations

Protocol Maturity / Standardization

Final; foundational to LUKSO blockchain and Universal Profiles; adopted in ERC-725Y form across identity-focused projects

Trust Framework

Key manager contract with role-based execution rights; claim verifier contracts for on-chain attestations; controller key hierarchy

Target Application Domain

Decentralized identity, self-sovereign identity (SSI), Universal Profiles, DAO membership, credential management, on-chain reputation

Deployment Model

Per-identity contract deployment; each user or entity has a dedicated ERC-725 contract instance

Standard Type

Identity Standard

Ecosystem

Ethereum; particularly adopted in LUKSO ecosystem
