cd payxn-bridgepay
npx hardhat compile

• Modify hardhat.config.ts and add etherscan api and sourcify
• Add arguments.js to verify contract

npx hardhat verify --constructor-args arguments.js --network sepolia TOKEN_ADDRESS
npx hardhat verify --constructor-args arguments.js --network sepolia 0xa18f2e81f10a1a89151e99433434dd5a0a09f759

• Run watch for bridges scripts

npx ts-node --files ./scripts/WatchForBridges.ts SOURCE_NETWORK SOURCE_TOKEN_ADDRESS DESTINATION_NETWORK DESTINATION_TOKEN_ADDRESS

npx ts-node --files ./scripts/WatchForBridges.ts sepolia 0xa18f2e81f10a1a89151e99433434dd5a0a09f759 base 0xdda5a1fcd29b7a765a3d8d4fc8cf4ee4fb0ec5be

npx ts-node --files ./scripts/WatchForBridges.ts base 0xdda5a1fcd29b7a765a3d8d4fc8cf4ee4fb0ec5be sepolia 0xa18f2e81f10a1a89151e99433434dd5a0a09f759

Requirements

Before you begin, you need to install the following tools:

• Node (>= v18.18)
• Yarn (v1 or v2+)
• Git

Quickstart

To get started with Scaffold-ETH 2, follow the steps below:

1. Clone this repo & install dependencies

git clone https://github.com/scaffold-eth/scaffold-eth-2.git
cd scaffold-eth-2
yarn install

2. Run a local network in the first terminal:

yarn chain

This command starts a local Ethereum network using Hardhat. The network runs on your local machine and can be used for testing and development. You can customize the network configuration in hardhat.config.ts.

3. On a second terminal, deploy the test contract:

yarn deploy

This command deploys a test smart contract to the local network. The contract is located in packages/hardhat/contracts and can be modified to suit your needs. The yarn deploy command uses the deploy script located in packages/hardhat/deploy to deploy the contract to the network. You can also customize the deploy script.

4. On a third terminal, start your NextJS app:

yarn start

Visit your app on: http://localhost:3000. You can interact with your smart contract using the Debug Contracts page. You can tweak the app config in packages/nextjs/scaffold.config.ts.

What's next:

• Edit your smart contract YourContract.sol in packages/hardhat/contracts
• Edit your frontend homepage at packages/nextjs/app/page.tsx. For guidance on routing and configuring pages/layouts checkout the Next.js documentation.
• Edit your deployment scripts in packages/hardhat/deploy
• Edit your smart contract test in: packages/hardhat/test. To run test use yarn hardhat:test
• You can add your Alchemy API Key in scaffold.config.ts if you want more reliability in your RPC requests.
