cf-cardano-worker

This worker server constantly checks for transactions on specific addresses on the Cardano blockchain, and stores them in a MongoDB database for later processing. The worker will check transactions for each address defined in a monitoring object (models/BlockachinMonitoring.js) and stores a corresponding transaction object (models/BlockachinTransaction.js) with a matching project key. The system will prioritize queries based on the recent activity on the address.

This server is also capable of processing transactions for a custodial CNFT staking system, the logic of which can be found in the stakingRewards.js file. The corresponding claim sessions (models/StakeClaim.js) are created by the Cardano Staking API server. This worker will process the incoming transactions and call the Cardano Node API to send back the tokens.

Requirements

The server requires a connection to a server running Cardano Node and DB Sync with PostgREST to query DB Sync data and Cardano Node API to submit transactions.

Environment variables

• DATABASE_URL - MongoDB Connection String
• CARDANO_API_SECRET - Shared secret with the Cardano Node API
• CARDANO_API_URL - URL of the Cardano Node API
• CARDANO_DB_URL - URL of the PostgREST API server

Running the system

Run the worker with node index.js
