To get started with development, copy the .env.example files in each package to .env and fill in the values in each of the projects inside of apps, as well as packages/protocol

Then, install dependencies and run the development server:

pnpm install
pnpm dev

This will start a local anvil node, deploy the contracts, start the indexer with API, and a demo frontend that integrates ECP.

If you are running locally, you need to make sure you are using a chain that:

• supports EIP 7702
• our contract is deployed on it
• supports 0x swaps

Then make sure you are using that chain in the demo app. In lib/wagmi.ts change the chain to the chain you are using.

Important: We used Metamask and base to test the EIP 7702. Make sure that chain you are testing is also supported by Metamask.

Based on chain you choose, you need to provide PONDER_RPC_URL_{chain_id} in .env file to enable indexing of the chain.
