Verifying contracts

Verifying a smart contract provides a link to its source code and attests that the source code matches the deployed bytecode.

Follow these steps to verify a contract on the Etherlink block explorer:

1. Find the deployed contract on https://explorer.etherlink.com/ or https://testnet.explorer.etherlink.com/.

2. On the Contract tab, click Verify & publish.

3. In the New smart contract verification window, select the license and verification method. In most cases, use the Solidity (Single file) verification method.

4. Under "Contract verification via Solidity (flattened source code)", in the Compiler field, select the same compiler version that you used to compile the contract.

5. In the EVM version field, select the same EVM version that you used to compile the contract.

6. If your compiler optimized the contract source code, select the Optimization enabled check box. This setting must match your compiler's setting.

7. Paste the source code of the contract in the Contract code field.

The page looks like this:

1. Click Verify & publish.

Now the block explorer shows the source code and ABI of the contract on the Contract tab.
