Like Lottery Contracts

Smart contracts for the Like Lottery project, deployed on Base network.

Installation

yarn install

Usage

Compile Contracts

yarn compile

Run Tests

yarn test

Deploy

1. Copy .env.example to .env and add your mnemonic phrase and API keys:

cp .env.example .env

2. Deploy to the desired network:

# Deploy to Base Sepolia testnet
yarn deploy:baseSepolia

# Deploy to Base mainnet
yarn deploy:base

# Deploy to local network
yarn node # In one terminal
yarn deploy:local # In another terminal

Verify Contracts

After deployment, verify your contracts:

CONTRACT_ADDRESS=<deployed-address> yarn verify:baseSepolia
# or
CONTRACT_ADDRESS=<deployed-address> yarn verify:base

Importing Deployed Contracts

When this package is published, you can import deployed contract addresses and ABIs:

JavaScript/TypeScript

import { LikeLottery, ChainId } from 'like-lottery-contracts';

// Get ABI
const abi = LikeLottery.abi;

// Get address for a specific chain
const address = LikeLottery.getAddress(ChainId.BASE);
// or
const baseSepoliaAddress = LikeLottery.addresses[ChainId.BASE_SEPOLIA];

// Get full deployment info
import { deployments, NetworkName } from 'like-lottery-contracts';
const deployment = deployments[NetworkName.BASE_SEPOLIA].LikeLottery;

Direct Access

You can also directly access deployment files:

import baseDeployment from 'like-lottery-contracts/deployments/base/LikeLottery.json';
import baseSepoliaDeployment from 'like-lottery-contracts/deployments/baseSepolia/LikeLottery.json';

Deployment Files

After deploying, the contract addresses and ABIs are automatically saved in the deployments directory:

deployments/
├── localhost/
│   ├── LikeLottery.json    # Full deployment info with ABI
│   └── addresses.json      # Simple address mapping
├── baseSepolia/
│   ├── LikeLottery.json
│   └── addresses.json
└── base/
    ├── LikeLottery.json
    └── addresses.json

Each LikeLottery.json contains:

• address: Contract address
• abi: Contract ABI
• transactionHash: Deployment transaction hash
• blockNumber: Deployment block number
• deployer: Deployer address
• chainId: Chain ID
• timestamp: Deployment timestamp

Networks

• Base Sepolia (testnet): Chain ID 84532
• Base (mainnet): Chain ID 8453
• Localhost: Chain ID 31337
