BUILD WITH SDKs

Four language SDKs sourced from projects/KryptoOS — integrate issuance, verification, and wallet flows without reimplementing cryptography.

TYPICAL INTEGRATION

Most applications need three capabilities: create or resolve a did:emp, request credentials from an issuer, and verify presentations on the server. SDKs wrap REST APIs and chain RPC with typed helpers.

  • TypeScript — web apps, issuer/verifier APIs
  • Rust — kryptos-core, native services, chain tooling
  • Python — operations scripts and backend automation
  • Dart — Eoonia Wallet and Ouranoos mobile apps
