0L Bridge Ethereum Development Network

This project sets up local dev net running under hardhat and implements 0L Bridge Escrow contract for Ethereum

Install

./setup-hardhat.sh

Compile contract

npx hardhat compile

Test contract

npx hardhat test

Test contracts on local network

1. Run test network

./run-local-node.sh

2. Deploy contracts

./deploy-local.sh

# deploy multisig voting option with min-votes = 2
./deploy-local.sh 2

3. Run contract methods

cd integration-tests
./test-escrow.sh

Contract addresses are saved in .escrow_bridge.config

Run Demo ETH agent

This is a depo agent to transfer funds from ETH to ETH. The agent periodically checks pending transfers and processes them

1. Start local test network and deploy contracts

./run-local-node.sh
./deploy-local.sh

2. run integration tests

cd integration-tests
./test-escrow.sh
# inspect output

3. Deposit funds

# receiver address on 0: chain: 0x06505CCD81E562B524D8F656ABD92A15
export transfer_id=0xeab47fa3a3dc42bc8cbc48c02182669d
npx ts-node  npx-scripts/deposit.ts pete 0x06505CCD81E562B524D8F656ABD92A15 10 "$transfer_id"

4. Check balance

npx ts-node  npx-scripts/get_balance.ts todd

Generate ABI

yarn run hardhat export-abi

Abis can be hound under abi directory
