Scroll Contract Deployment Demo

This project demonstrates how to use hardhat or foundry to deploy a contract in Scroll's rollup network. This project contains a simple contract that will lock a certain amount of Ether in the deployed contract for a specified amount of time.

Prerequisites

• Network setup: https://guide.scroll.io/user-guide/setup

Deploy with Hardhat

1. If you haven't already, install nodejs and yarn.
2. Run yarn install to install dependencies.
3. Create a .env file following the example .env.example in the root directory. Change PRIVATE_KEY to your own account private key in the .env.
4. Run yarn compile to compile the contract.
5. Run yarn deploy:scrollTestnet to deploy the contract on the Scroll Alpha Testnet.
6. Run yarn test for hardhat tests.

Deploy with Foundry

1. Install Foundry.

   curl -L https://foundry.paradigm.xyz | bash
   foundryup

2. Build the project.

   forge build
   

3. Deploy the contract.

   forge create --rpc-url https://alpha-rpc.scroll.io/l2 \
     --value <lock_amount> \
     --constructor-args <unlock_time> \
     --private-key <your_private_key> \
     --legacy \
     contracts/Lock.sol:Lock
   

• <lock_amount> is the amount of ETH to be locked in the contract. Try setting this to some small amount, like 0.0000001ether.
• <unlock_time> is the Unix timestamp after which the funds locked in the contract will become available for withdrawal. Try setting this to some Unix timestamp in the future, like 1696118400 (this Unix timestamp corresponds to October 1, 2023).

For example:

forge create --rpc-url https://alpha-rpc.scroll.io/l2 --value 0.00000000002ether --constructor-args 1696118400 --private-key 0xabc123abc123abc123abc123abc123abc123abc123abc123abc123abc123abc1 --legacy contracts/Lock.sol:Lock

Verify

npx hardhat verify --network scrollTestnet {contract-address} {contract-args}
