The Solana SDK generates proofs for private transactions.

​
Circuit path

The SDK reads the circuit path from:
  • ARCANE_CIRCUIT_PATH
  • CIRCUIT_PATH
  • VITE_CIRCUIT_PATH
The default value is: 
/transaction2
The value is used as the Groth16 circuit path or URL for prover artifacts.

​
Production guidance

  • Keep circuit configuration server-side in backend-managed integrations.
  • Treat proof generation as a separate failure domain.
  • Record proof-generation failures in operation history.
  • Retry with the same product reference when the product action is still valid.
