World ID State Bridge for Linea

Description

This repository will contain the code for the Worldcoin state bridge, specifically designed for the Linea blockchain. The bridge facilitates state synchronization between the WorldID Ethereum mainnet deployment and the Linea network.

Deployments

The addresses of the contract deployments for production and staging will be available in docs/deployments.md.

Supported Networks

• Linea (zkEVM Layer 2 on Ethereum)

Usage

This is a list of the most frequently needed commands.

Build

Build the contracts:

$ forge build

Clean

Delete the build artifacts and cache directories:

$ forge clean

Compile

Compile the contracts:

$ forge build

Coverage

Get a test coverage report:

$ forge coverage

Deploy

Deploy to Anvil:

$ forge script script/Deploy.s.sol --broadcast --fork-url http://localhost:8545

For this script to work, you need to have a MNEMONIC environment variable set to a valid BIP39 mnemonic.

For instructions on how to deploy to a testnet or mainnet, check out the Solidity Scripting tutorial.

Format

Format the contracts:

$ forge fmt

Gas Usage

Get a gas report:

$ forge test --gas-report

Lint

Lint the contracts:

$ bun run lint

Test

Run the tests:

$ forge test

Generate test coverage and output result to the terminal:

$ bun run test:coverage

Generate test coverage with lcov report (you'll have to open the ./coverage/index.html file in your browser, to do so simply copy paste the path):

$ bun run test:coverage:report
