Try Product Hub Integration quickstart JSON

Pre-execution firewall

Quote routes, run KYT, check provider health, simulate failures, collect approvals, and export proof packets before execution is even requested.

Execution boundary

ExecutionRun and idempotency exist, but DisabledSigner keeps signing and on-chain submission off by default.

Production-ready console

Workspace auth, rate limits, usage metrics, role-gated approvals, tamper-evident audit, and exportable proof JSON for design partners.

Why teams choose Starail

Built for pre-execution control — not another wallet or bridge.

Pre-execution firewall

Every transfer is quoted, screened, simulated, and approved before anyone can even request signing.

Audit-ready proof

Hash-chained audit events and exportable proof packets for compliance and design-partner reviews.

Safe by default

Signing and on-chain submission stay off until your organization explicitly enables execution boundaries.

Rail intelligence

Live map of issuers, chains, bridges, and provider health — so decisions are informed, not guessed.

Operating model
