Identity & Privacy

ERC-3643 provides identity and compliance checks for ordinary token transfers; mint and forcedTransfer use distinct privileged paths and burn has its own rules. Read the deployed identity and compliance modules instead of assuming every operation uses the same gate.

ERC-5192 defines a minimal soulbound interface in which locked(tokenId) reports whether an ERC-721 token is currently non-transferable. A compliant implementation can emit Locked and Unlocked, so “soulbound” should be shown as non-transferable while locked rather than as a universal forever guarantee.

Stages: Approving & Permissioning, Asset Management

ERC-5484 extends ERC-721 for soulbound tokens whose burn authorization is agreed before issuance. The issuer presents metadata and burnAuth, obtains the receiver's signature off-chain, then issues the token; after issuance burnAuth is immutable and transfer remains disabled. The interface has no pending accept/decline token state.

ERC-5564 standardizes one-time stealth-address generation and announcements that compatible recipients scan to discover payments. It can reduce public links to a recipient's main wallet, but funding, onward transfers, and other disclosed metadata can reveal those links.

Stages: Authentication & Identity, Executing Transactions

ERC-6538 defines a registry that maps a registrant address and schemeId to stealth meta-address bytes. It helps an ERC-5564 client discover a private-receive key; it does not define name resolution, profile verification, unregister/privacy erasure, or payment settlement.

ERC-7231 binds a custom set of Web2/Web3 identity records to an NFT through an identitiesRoot and verifier-specific proof. Its required interface exposes setIdentitiesRoot, getIdentitiesRoot, and verifyIdentitiesBinding; it does not define add/remove identity methods or guarantee that the bound accounts belong to one real human.

Stages: Authentication & Identity

ERC-7627 defines encrypted on-chain messaging with public-key registration, algorithm metadata, session IDs, and message events. It provides updatePublicKey, sendMessage, and getUserPublicKey; key derivation, private-key recovery, inbox enumeration, and event indexing remain integration responsibilities.

Stages: Specialized Interactions

ERC-5114 defines an immutable soulbound badge binding to a specific NFT and content-addressable badge metadata. It does not define an issuer registry, revocation function, identity verification, or validity status; show those as separate issuer or application policy when present.
