Everything you need to go from zero to signed deposit webhooks (or Telegram alerts) on TRON.

First confirmed-deposit webhook in 5 minutes — curl or TypeScript SDK, plus the no-code Telegram path.

Authentication, watches, events, rate limits, and the exact payload schema.

Non-custodial by design: what we store, what we never touch, and what you must protect.
