Generating a Solana Log Proof

After your transaction has been confirmed on Solana, you'll need to request a state proof from Polymer's Prove API.

Proof Request Endpoint​

The Prove API follows a JSON-RPC format:

POST <https://proof.testnet.polymer.zone>

API Authentication​

Include your API key in the request header:

Authorization: Bearer YOUR_API_KEY

Proof Request Format​

Here's the expected request format:

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "polymer_requestProof",
  "params": [{
    "srcChainId": 2, // Represents Solana within Polymer Network 
    "txSignature": "YOUR_SOLANA_TRANSACTION_SIGNATURE",
    "programID": "YOUR_SOLANA_PROGRAM_ID"
  }]
}

Parameters:

  • srcChainId: 2 (representing Solana in Polymer's chain ID system)
  • txSignature: The Solana transaction signature containing your log
  • programID: Your Solana program ID that emitted the log (Base58 encoded)

Proof Response and Polling​

The initial response will include a job ID:

{
  "jsonrpc": "2.0",
  "id": 1,
  "result": "167462"
}

You'll need to poll for the proof using this job ID:

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "polymer_queryProof",
  "params": ["167462"]
}

The response will eventually include the proof when ready:

{
  "jsonrpc": "2.0",
  "id": 1,
  "result": {
    "status": "complete",
    "proof": "BASE64_ENCODED_PROOF_DATA"
  }
}
