Seed Historic Quotes (Optional)

Manually run the seed function in src/historic-quote/historic-quote.service.ts to populate the database with historic quotes for history-dependent functionalities such as the simulator.

Change Network

To switch Carbon Backend's network for different deployments, follow these steps:

1. Replace Smart Contract Files:

   • Replace files in src/contracts/mainnet with those from the new deployment.

2. Modify CoinMarketCap Service:

   • Adjust src/coinmarketcap/coinmarketcap.service.ts to align with the new network.
   • For guidance, check the CoinMarketCap API documentation.

3. Modify CoinGecko Service:

   • Adjust src/quote/coingecko.service.ts to match the requirements of the new network.
   • Refer to the CoinGecko API documentation for assistance.

By following these steps, you can seamlessly switch Carbon Backend's network to suit your deployment or environment.
