Verify a smart contract on Monad Explorer using Foundry

note

Currently, the RPC and block explorer are not public; this page will be updated as soon as they are.

We appreciate your patience.

Foundry Monad template (Recommended)

If you are using foundry-monad template, you can simply run the below command:

forge verify-contract <contract_address> <contract_name>

Example:

forge verify-contract 0x195B9401D1BF64D4D4FFbEecD10aE8c41bEBA453 src/Counter.sol:Counter

Default Foundry Project

tip

If you use foundry-monad you can skip the configuration step

1. Update foundry.toml with Monad Configuration

[profile.default]
src = "src"
out = "out"
libs = ["lib"]

# Monad Configuration
# TODO: Add RPC URL and Chain ID
eth-rpc-url="MONAD_RPC_URL"
chain_id = "MONAD_CHAIN_ID"


# TODO: Add Explorer URL and Chain ID
[etherscan]
monadDevnet = { key = "DUMMY_VALUE", url = "EXPLORER_URL", chain = MONAD_CHAIN_ID }

2. Verify the contract using the command below:

forge verify-contract <contract_address> <contract_name>

Example:

forge verify-contract 0x195B9401D1BF64D4D4FFbEecD10aE8c41bEBA453 src/Counter.sol:Counter

On successful verification of smart contract, you should get a similar output in your terminal:

Start verifying contract `0x1355a4f7829161a4d27BDb8970D32b89ef89A1Be`
