@ensdomains/op-verifier

A complete Solidity library that facilitates sending CCIP-Read requests for Optimism state, and verifying the responses.

For a detailed readme and usage instructions, see the monorepo readme.

Testing

Start up a devnet by following Optimism's instructions here.

Then, deploy the L2 contract:

bun run hardhat deploy --network opDevnetL2

Followed by the L1 contract:

bun run hardhat deploy --network opDevnetL1

The L1 contracts contain a reference to the L2 contract, and so will require redeploying if the L2 contract changes.

Finally, run the tests:

hardhat test --network opDevnetL1

The tests will require small modifications to work on public testnets; specifically, contract addresses are currently fetched from http://localhost:8080/addresses.json; this will need to be made conditional on the network being used.
