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 only supported explorers are:

• Blockscount explorer

• ZKsync 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!
