Smart Contract Verification

​https://explorer.harmony.one/verifycontract​
Right now, we support verification only for one single solidity file - therefore, before deployment and verification, you will need to flatten all solidity sources to one file.
1. Flatten your Solidity Files
To flatten your solidity files we recommended to use Truffle Flattener lib.
npm install truffle-flattener -g
truffle-flattener <solidity-files>
Or you can use any other flattener lib.
2. Deploy Contract to Harmony
To easy the verification we recommend the contract deployment using Harmony Remix.
3. Verify Contract
You can verify your contract here: https://explorer.harmony.one/verifycontract​
Verify Contract
It is important to use the correct parameters (same as on deployment):
Contract address
Contract name
Compiler version
Optimizer
Chain Type (mainnet or testnet)
Sources
Imported libs
Then click on Sumbit button. If all params was correct - you should to see Success message, or Error if bytecodes are not equal. On Success case - you contract will verify and you will see all contract details on contract explorer page.
