Read https://lirchain.com/llms-full.txt and integrate LirChain into this project.

Goal: [give every user their own USDT deposit address and credit their balance when a deposit arrives].

Keep the API key in an environment variable named LIRCHAIN_API_KEY, never in the frontend.
Add a webhook endpoint for the events and make it safe to receive the same event twice.
