Verify using Foundry

Verifying a smart contract on the blockchain is an essential step to ensure its transparency, security and ease of interaction for users and other developers.

This project is a demonstration of how to verify a contract on blockscout using foundry.

1. Clone repository

git clone https://github.com/alt-research/contract-verify-sample.git

2. Navigate to `foundry` folder

cd foundry

3. Install dependencies

forge install

4. Deploy sample contract

forge create --rpc-url <L2 RPC URL> --private-key <Your Private Key> src/Counter.sol:Counter
// deploy address = 0x5FC8d32690cc91D4c39d9d3abcBD16989F875707

5. Verify sample contract

forge verify-contract --verifier blockscout --verifier-url <L2 Verifier URL > --chain-id <Chain ID> <Contract Address> src/Counter.sol:Counter

The output looks like below:

Start verifying contract `0x5FC8d32690cc91D4c39d9d3abcBD16989F875707` deployed on 1637450

Submitting verification for [src/Counter.sol:Counter] 0x5FC8d32690cc91D4c39d9d3abcBD16989F875707.
Submitted contract for verification:
Response: `OK`
GUID: `5fc8d32690cc91d4c39d9d3abcbd16989f875707661fa406`

6. Confirm verification

After executing the relevant command, visit the Xterio explorer (Mainnet / Testnet) to see your contract's status.
