Description

Goal: Connect the backend to your chosen blockchain node.

Explanation: This is your bridge between backend and chain. You’ll configure:

  • A Web3 provider (ethers.providers.JsonRpcProvider or Nethereum.Web3).

  • Wallet connection for the admin’s private key.

  • Error handling + connection test route.

Deliverables:

  • /services/blockchain.js or BlockchainService.cs

  • GET /blockchain/status endpoint → returns "Connected to Polygon (Kenya)"

Contributor guide

Research direction
Implement a blockchain service using ethers.js to connect to a Polygon node. Set up a JsonRpcProvider with the node URL, configure the admin wallet with a private key, add error handling, and create a GET /blockchain/status endpoint that returns a connection status message.
