ERC-1462 tries to be a minimal security-token baseline, not an all-in-one tokenization framework. Its main additions are preflight compliance checks plus optional document binding.
The decisive mechanism is the split between transfer, transferFrom, mint, and burn checking. Rather than embedding one monolithic policy engine, the standard exposes narrow hooks where issuers can plug in whatever compliance logic they need.
The use of ERC-1066 status codes is a real design choice, not a cosmetic one. It turns token compliance into an inspectable interface with richer return semantics than a simple boolean or revert.
The standard is intentionally policy-agnostic about how permissioning is implemented: whitelist contracts, blacklists, built-in token logic, or oracle-assisted checks are all explicitly allowed.
The document functions matter because ERC-1462 treats legal/document binding as part of the token interface itself, while still avoiding a larger identity or credential framework.
The motivation section is especially useful because it positions ERC-1462 against ERC-1400 and ERC-1404, arguing for a smaller and more modular base layer.
Specific source signals worth retaining
EIP motivation: strongest source for the proposal’s critique of broader or narrower alternatives and for why it chose a minimal interface surface.
EIP specification: best source for the actual checking hooks, status-code requirement, and document functions.
Reference implementation README: useful confirmation that the proposal was paired with concrete Solidity interfaces and not only prose.
Discussion thread: useful for situating ERC-1462 inside the 2018 security-token-standards wave even though the proposal later became stagnant.
Why this entry belongs in the corpus
It provides a lower-bound comparison for tokenized-asset compliance systems already in the corpus, especially ERC-3643, ONCHAINID, Tokeny, and Chainlink ACE.
It helps separate three layers that later systems often package together: action-level transfer checking, identity/policy sourcing, and document/legal binding.
The durable insight is that tokenized-asset compliance can begin as a small set of permission hooks and attached documents, before later stacks add dedicated identity registries, role frameworks, monitoring, and admin tooling.
