Polymer at a Glance

App-Side Process​

The application workflow follows these key steps:

  • Event Emission: App emits custom event from their own contract (not Polymer's source-side contract)
  • Proof Request: App requests proof from backend using Prove API (RPC-like call)
  • Proof Submission: App relayer submits proof to destination chain contract (pre-configured with Polymer prover)
  • Validation: Single method call validates proof and returns complete event data as defined by app developer

Flow Summary: App emits → Request proof → Submit to validator contract → Get validated event data

Prove API (Off-chain)​

  • Request Proof: Use proof_request method → returns jobID
  • Poll for Result: Use proof_query with jobID to get proof
  • Scope: Designed to prove individual logs/events

CrossL2ProverV2 Contract (On-chain)​

  • Validates Polymer rollup state roots
  • Verifies log authenticity using proofs
  • Allows proof inspection via static calls
