Violet

Violet Protocol provides privacy-preserving, reusable on-chain compliance and identity infrastructure for decentralized finance (DeFi). Its products — VioletID, Full AML/KYC screening, GeoFencing, and Sybil resistance — let crypto businesses meet regulatory requirements such as anti-money-laundering, sanctions screening, geo-blocking, accredited-investor verification, and proof of unique personhood. Integration is SDK and smart-contract based: Violet issues Ethereum Access Tokens (EATs) — OAuth 2.0-compliant, EIP-712-signed compliance assertions that carry no PII — and maintains the on-chain VioletID Registry that maps wallet addresses to verified compliance statuses, all built on W3C Decentralized Identifier and Verifiable Credential standards.

Violet is profiled on the APIs.io network. Tagged areas include Company, Compliance, Identity, DeFi, and Blockchain.

Violet’s developer surface includes documentation, developer portal, getting-started guide, API reference, support, signup flow, authentication, and 9 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/violet: open an issue to ask a question, or submit a pull request to add artifacts.
