Deploying a Contract on Moonchain

CAUTION

Make sure you are using a test/throwaway wallet, to be save. Never reveal the private key of your main wallet!

This guide will help you deploy a smart contract on Moonchain (Geneva Testnet) using Foundry.

Prerequisites

• Foundry is installed.
• You have the private key handy to an account that has Test $MXC Tokens on Moonchain Geneva (to pay the transaction fee for deploying the contract).
  • Retrieve the private key with MetaMask.
  • Generate wallet keys with OpenSSL.
• Have some Test $MXC Tokens on Moonchain Geneva:
  • Request Test $MXC Tokens from the faucet.

Steps

Create a Project with Foundry

To scaffold a new Foundry project, run:

forge init hello_foundry $$ cd hello_foundry

Deploy the Contract

Replace YOUR_PRIVATE_KEY below with your private key that has some Test $MXC Tokens on Moonchain Geneva testnet.

Deploy the contract located at src/Counter.sol:

forge create --rpc-url https://geneva-rpc.moonchain.com --private-key YOUR_PRIVATE_KEY src/Counter.sol:Counter

INFO

If you encounter an error --> ERROR: (Code: -32000, message: contract creation code storage out of gas, data: None), consider deploying using Remix IDE.

View Your Contract

Paste the address from the output into the Moonchain Geneva Block Explorer and verify that the contract was deployed.
