Pluto Onchain Verifier

This is a simple contract that verifies signatures from a given notary.

The contract is deployed on Base Sepolia at 0xeB3Ba25400A4d716d091090942705aD51d04B7ea

Deployment & Verification

This command will deploy the contract and automatically verify it on Basescan.

1. Set your Private Key: This is required to sign the deployment transaction.

   export PRIVATE_KEY="<YOUR_PRIVATE_KEY>"

2. Set your Basescan API Key: You need an API key from Etherscan (which works for Basescan) to publish the source code. You can get one for free from the Etherscan website.

   export ETHERSCAN_API_KEY="<YOUR_ETHERSCAN_API_KEY>"

3. Run the deployment script:

   forge script script/SignatureChecker.s.sol:VerifierScript \
     --rpc-url https://sepolia.base.org \
     --private-key $PRIVATE_KEY \
     --broadcast \
     --verify \
     --verifier etherscan \
     --etherscan-api-key $ETHERSCAN_API_KEY \
     -vvvv

Manual Verification

If the deployment script succeeds but verification fails for some reason, you can verify it manually.

1. Find your contract address and constructor arguments: After a successful deployment, Foundry saves a receipt in the broadcast/ directory. Look inside broadcast/SignatureChecker.s.sol/84532/run-latest.json.

   • The contract address is under receipts[0].contractAddress.
   • The constructor arguments are the long hex string under transactions[0].constructorArguments.

2. Run the verify command:

   forge verify-contract <CONTRACT_ADDRESS> src/Verifier.sol:PlutoAttestationVerifier \
     --chain base-sepolia \
     --verifier etherscan \
     --etherscan-api-key $ETHERSCAN_API_KEY \
     --constructor-args <CONSTRUCTOR_ARGS>
