Create2 Verification

Verify counterfactual smart contracts created with the opcode CREATE2 with session.

note

Session-based API is only meant for the sourcify.dev UI. Because it makes use of session cookies and it is not possible have Access-Control-Allow-Origin: * with credentials: true, meaning these endpoints can only be used on explicitly set domains on the browser. (e.g. sourcify.dev). Please use the verification API if you want Sourcify on your frontend.

  "verificationId": "0xedb48e28ff41f826b1fbb20a7601e5f79bd0b1c08c36214de5b6a1e00c1bdb46",
  "deployerAddress": "0x0000...",
  "salt": "0xa2fd", // hex string or number
  "abiEncodedConstructorArguments": "0x0000000000000000000000000000000000000000000000000000000000000001",
  "create2Address": "0x0000...",
  "clientToken": "CREATE2_CLIENT_TOKEN"
}

The verificationId is the Sourcify's session contract id, it needs to be the verificationId of a contract compiled by /session/create2/compile. On the UI it is done automatically.
The salt can be a hex string starting with 0x or a decimal number in string format. The value will be padded to 32 bytes before being used in the CREATE2 opcode.
