jup.sh 0.1.0-alpha.12 Draft Release Notes

Status: draft.

v0.1.0-alpha.12 is planned as a transaction request preflight checkpoint. It makes transaction readiness inspectable before a wallet or agent attempts the Solana Pay POST path.

This draft still does not construct a Solana transaction or call Jupiter swap transaction APIs.

What This Draft Adds

• Transaction request preflight API:
  • GET /api/transaction-requests/:intentId/preflight.
• CLI preflight command:
  • jup-sh intent preflight <intent_id> --json.
• Shared preflight shape with:
  • transaction request endpoint;
  • Solana Pay URL;
  • readiness status;
  • blocking reason;
  • explicit transactionImplemented: false.
• Server smoke coverage for blocked and approved preflight states.
• Alpha CLI smoke coverage for blocked and approved preflight states.

Safety Boundary

Preflight is not authorization and not settlement. It is a machine-readable gate that tells agents and local tooling why a transaction request POST would fail today.

The useful invariant is:

transactionImplemented === false

Until that changes in a later checkpoint, clients must not expect a signable transaction from jup.sh.

Current Boundary

The npm alpha package remains jup-sh@0.1.0-alpha.7 until a runtime release is prepared and published.

Verification

Run:

npm run release:check
