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.
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.
