Verify Contract Code

To verify and publish your Solidity Source Code, please follow 3 steps:

  • STEP 1. Enter your Contract Source Code below.
  • STEP 2. If the Bytecode generated matches the existing Creation Address Bytecode, the contract is then Verified.
  • STEP 3 Contract Source Code is published online and publicably verifiable by anyone.


  1. To verify Contracts that accept Constructor arguments, please enter the ABI-encoded Arguments in the last box below.
  2. For debugging purposes if it compiles correctly at Browser Solidity , it should also compile correctly here.
  3. Contracts that use "imports" will need to have the code concatenated into one file as we do not support "imports" in separate files. You can try using the Blockcat solidity-flattener
  4. We do not support contract verification for contracts created by another contract
  5. There is a timeout of up to 45 seconds for each contract compiled. If your contract takes longer than this we will not be able to verify it.

Contract Address*

Contract Name*

Must match the ContractName in the Source Code or in a MultiPart Contract it should match the ContractName you deployed


EVM version*

Enter the Solidity Contract Code below *

The following are optional Parameters which you might need to provide depending your contract


Optimization Setting(Runs & Constructor Arguments ABI-encoded & ContractLibrary Address)
