Off-Chain Development

Overview

This is an off-chain development project built in Node.js + TypeScript that uses @solana/web3.js and @solana-developers/helpers dependencies. It goes through all the basic actions with the Solana blockchain. This project is linked to the on_chain_solana_rust repository, which provides the on-chain interactions required (smart contracts).

Configuration

To configure the project, follow these steps:

1. Create a .env file in the project root and add the necessary environment variables:

ENVIRONMENT=<your_environment>
MNEMONIC_PASSWORD=<your_passphrase>
SECRET_KEY=<[your_secretkey]>
SEED_PHRASE=<your_seedphrase>

Clusters

The project is built to run on any cluster, but I highly recommend to run it locally.

1. run solana-test-validator on your terminal
2. update your .env: ENVIRONMENT="http://localhost:8899"
3. run the scripts: ts-node <file>
