Lido L2

This project contains the implementations of the L2 ERC20 token bridges for Arbitrum and Optimism chains. The current solution allows transferring ERC20 tokens between L1 and L2 chains.

To retrieve more detailed info about the bridging process, see the specifications for certain chains:

Project setup

Clone the repo:

git clone [email protected]:lidofinance/lido-l2.git
cd ./lido-l2

Install dependencies:

npm install

Compile the contracts:

npm run compile

Configure ENV variables

The simplest way to create .env file is via cloning the .env.example file:

cp .env.example .env

Fill the newly created .env file with the required variables. See the Project Configuration section for the complete list of configuration options.

Bridge deployment

The configuration of the deployment scripts happens via the ENV variables. The following variables are required:

TOKEN - address of the token to deploy a new bridge on the Ethereum chain.
NETWORK - name of the network environments used by deployment scripts. Allowed values: mainnet, goerli.
FORKING - run deployment in the forking network instead of real ones
ETH_DEPLOYER_PRIVATE_KEY - The private key of the deployer account in the Ethereum network is used during the deployment process.
ARB_DEPLOYER_PRIVATE_KEY - The private key of the deployer account in the Arbitrum network is used during the deployment process.
OPT_DEPLOYER_PRIVATE_KEY - The private key of the deployer account in the Optimism network is used during the deployment process.
L1_PROXY_ADMIN - The address to grant admin rights of the OssifiableProxy on the L1 bridge
L1_BRIDGE_ADMIN - Address to grant the DEFAULT_ADMIN_ROLE on the L1 bridge
L2_PROXY_ADMIN - The address to grant admin rights of the OssifiableProxy on the L2 bridge
L2_BRIDGE_ADMIN - Address to grant the DEFAULT_ADMIN_ROLE on the L2 bridge

The following ENV variables are optional and might be used to make an additional setup of the bridge after the deployment:

L1_DEPOSITS_ENABLED - whether the deposits are enabled on the L1 after the deployment. By default, deposits are disabled.
L1_WITHDRAWALS_ENABLED - whether the withdrawals are enabled on the L1 after the deployment. By default, withdrawals are disabled.
L1_DEPOSITS_ENABLERS - array of addresses to grant DEPOSITS_ENABLER_ROLE on the L1 bridge.
L1_DEPOSITS_DISABLERS - array of addresses to grant DEPOSITS_DISABLER_ROLE on the L1 bridge.
L1_WITHDRAWALS_ENABLERS - array of addresses to grant WITHDRAWALS_ENABLER_ROLE on the L1 bridge.
L1_WITHDRAWALS_DISABLERS - array of addresses to grant WITHDRAWALS_DISABLER_ROLE on the L1 bridge.
L2_DEPOSITS_ENABLED - whether the deposits are enabled on the L2 after the deployment. By default, deposits are disabled.
L2_WITHDRAWALS_ENABLED - whether the withdrawals are enabled on the L2 after the deployment. By default, deposits are disabled.
L2_DEPOSITS_ENABLERS - array of addresses to grant DEPOSITS_ENABLER_ROLE on the L2 bridge.

Deploying Arbitrum gateway

To run the deployment of the ERC20 token gateway for the Ethereum <-> Arbitrum chains use the following command:

npm run arbitrum:deploy

Deploying Optimism bridge

To run the deployment of the ERC20 token gateway for the Ethereum <-> Optimism chains use the following command:

npm run optimism:deploy

Tests running

Unit tests

To run unit tests use one of the following commands:

# Run tests for both Arbitrum and Optimism bridges
npm run test:unit

# Run tests only for Arbitrum gateway
npm run arbitrum:test:unit

# Run tests only for Optimism bridge
npm run optimism:test:unit

Integration tests

Before running integration tests, run the hardhat forked nodes in the standalone tabs corresponding to TESTING_ARB_NETWORK \ TESTING_OPT_NETWORK env variable or if it's not set use mainnet network. Example of the commands for the mainnet network:

# Required to run both Arbitrum and Optimism integraton tests
npm run fork:eth:mainnet

# Required to run Optimism integration tests
npm run fork:opt:mainnet

# Required to run Arbitrum integration tests
npm run fork:arb:mainnet

The integration tests might be run via the following commands:

# Run integration tests for both Arbitrum and Optimism bridges
npm run test:integration

# Run integration tests for Arbitrum bridge
npm run arbitrum:test:integration

# Run integration tests for Optimism bridge
npm run optimism:test:integration

Additionally, tests might be run on the deployed contracts. To do it, set the following variables values in the .env file:

# Activates testing on already deployed contracts
TESTING_USE_DEPLOYED_CONTRACTS=true
# Address of the account which has tokens to test
TESTING_L1_TOKENS_HOLDER=

# Addresses of the Arbitrum gateway

TESTING_PRIVATE_KEY TESTING_OPT_LDO_HOLDER_PRIVATE_KEY TESTING_ARB_LDO_HOLDER_PRIVATE_KEY

To run E2E tests use the following commands:

# Run E2E tests for both Arbitrum and Optimism bridges
npm run test:e2e

# Run E2E tests for Arbitrum bridge
npm run arbitrum:test:e2e

# Run E2E tests for Optimism bridge
npm run optimism:test:e2e

Additionally, tests might be run on the deployed contracts. To do it, set the following variables values in the .env file:

# private key of the tester. It must have tokens for testing
TESTING_PRIVATE_KEY=

# Addresses of the Arbitrum gateway
TESTING_ARB_NETWORK=
TESTING_ARB_L1_TOKEN=
