Foundry

Install OraichainEVM by following the full instructions provided in the documentation.

Create Foundry Project

Create a directory for your contracts and initialize it:

forge init oraichain-evm-foundry
cd oraichain-evm-foundry

For now, let’s check what the default template looks like:

tree . -d -L 1
.
├── lib
├── script
├── src
└── test

5 directories

Open src/Counter.sol with the following contract:

```solidity
// SPDX-License-Identifier: UNLICENSED
pragma solidity ^0.8.13;

contract Counter {
    uint256 public number;

    function setNumber(uint256 newNumber) public {
        number = newNumber;
    }

    function increment() public {
        number++;
    }
}

```

Compile the contract:

forge build

Anvil

Anvil is a fast local Ethereum development node.

Anvil is part of the Foundry suite and is installed alongside forge, cast and chisel. If you haven’t installed Foundry yet, see Foundry installation.

To fork against a live OraichainEVM network run:

anvil --fork-url <RPC_URL>

Deploy Contract

Migrate your contract in the foundry terminal:

forge create src/Counter.sol:Counter --rpc-url <RPC_URL> --private-key <PRIVATE_KEY> --broadcast

You should see deployment logs in the OraichainEVM terminal for each transaction.

Run Foundry Tests

Run the tests using the OraichainEVM node:

forge test test/Counter.t.sol --rpc-url <RPC_URL>

This will confirm the contract's functionality.

Run Foundry Script

To execute a script on OraichainEVM, run:

forge script script/Counter.s.sol --rpc-url <RPC_URL>

earched Pre-requisite reading installation run a node search.
