Repo — Protocol

Examples showing how you can use the @f8n/fnd-protocol npm package and integrate with Foundation smart contracts.

Set up the repository with:

yarn
yarn build

Testing

To test using a local deployment of the Foundation contracts, run:

yarn test

This uses the test/helpers/deploy.ts helper file to deploy Foundation contracts to your local machine for testing.

Mainnet fork

Alternatively you can test your contracts using a mainnet fork. Once forked, new contract deployments and any other transactions sent happen on your local machine only. This is a great way to confirm that your contracts work as expected with the latest Foundation contracts.

First create a .env file (you can use .env.example as a template) and set the RPC endpoint. We use Alchemy but any RPC provider should work.

Then you can test with:

yarn test-mainnet-fork

This uses the test-mainnet-fork/helpers/getFoundationContracts.ts helper file to get Typechain instances of each of the Foundation contracts, reading the addresses from our NPM package.

We have also included helper functions such as impersonate to ease interacting with the fork.

Example scripts

Some example scripts are included in the scripts directory to demonstrate various ways you may integrate with Foundation contracts or the data it logs on-chain. The scripts/rpc directory shows integrations using just an RPC endpoint such as Alchemy and the scripts/subgraph directory shows an alternative approach using our hosted subgraph instance.

If you have a question on how to use the Foundation contracts, please post to the discussions - maybe we could create another example script to help you and others.
