Contract Verification

The titanoboa tool comes with built in contract verification. To make life easier, we created a wrapper function called moccasin_verify that you can use to verify contracts.

1. Setup your explorer

In your moccasin.toml add your explorer details:

explorer_uri = "https://explorer.sepolia.era.zksync.dev"
explorer_type = "zksyncexplorer"
explorer_api_key = "None"

Some networks, like sepolia-zksync, have some of these details defaulted for you. You can check out the Explorer and Network Default Information page to see what’s available. As of today, the supported explorers are:

• Blockscount explorer

• ZKsync explorer

• Etherscan explorer

2. Add moccasin_verify to your script

In your script, let say, named deploy_and_verify.py, you can run the following code:

def moccasin_main():
    active_network = get_active_network()
    counter = Counter.deploy()
    print("Counter deployed at", counter.address)
    result = active_network.moccasin_verify(counter)
    result.wait_for_verification()
    print("Counter verified")

3. Run your script

mox run deploy_and_verify.py --network my_network

That’s it!
