§ DEVELOPERS — DOCUMENTATION
Build on the rail. In a week, not a quarter.
Concept guides, integration runbooks, language SDKs and a complete API reference. Everything you need to ship from sandbox to production.
Start here
QUICKSTART
Your first transaction
Provision a sandbox, mint test cash, send a cross-border payment and verify the attestation. 15 minutes end to end.
CONCEPTS
The mental model
DIDs, credentials, tokens, settlements, attestations. The five primitives every other concept reduces to.
PRODUCTION
Going live
Compliance review, key ceremony, HSM provisioning, monitoring, runbooks and the production cutover checklist.
By service
Identity
Enrol users, issue credentials, request ZK proofs, manage recovery and revocation.
Tokenization
Choose a template, set transfer rules, mint, manage corporate actions and lifecycle events.
Payments
Quote, route, send, attest. ISO 20022 messages, FX, multi-leg settlement and reversals.
Treasury
Policy-as-code, sweeps, hedging, liquidity routing and reporting integrations.
By stack
- SDKs. First-party language libraries for TypeScript, Python, Go, Rust, Java, C#, Kotlin, Swift, Ruby, PHP and Elixir.
- API surface. REST and GraphQL for application code, gRPC for service mesh, WebSockets for event streams.
- Messaging. ISO 20022 PACS, PAIN, CAMT message mappings. Adapters for SWIFT, SEPA INST, FedNow, RTP, FPS, PIX.
- Ledger. Read replicas, change-data-capture streams and the canonical event log.
Runbooks
Step-by-step procedures for the operations that matter most.
- Onboarding a new corridor. Liquidity provider configuration, FX rate sources, compliance checks.
- Issuing a new token template. Template review, rule validation, multi-chain mint coordination.
- Key ceremony. HSM provisioning, MPC distribution, role separation, attestation archive.
- Incident response. Severity classification, escalation paths, regulator and counterparty communication.
