Node.js / TRON Blockchain Developer – Automated P2P Crypto Escrow System
Budget: $10 – $30 USD
Project Overview
We have an operational private Telegram system (OVX Gate) built on Node.js, PostgreSQL, and Express. Phase 1 (Onboarding & Claude AI KYC) is complete. We need a developer to implement Phase 2: An automated USDT TRC20 Escrow Trading System.
Scope of WorkBot Commands: Build handlers for /escrow, /confirm, /dispute, and /trades. TRON Integration: Use tronweb to automatically sign/broadcast USDT TRC20 payouts to sellers minus a 0.5% fee. Watcher Service: Create a background service via TronGrid API to poll the escrow wallet every 30 seconds and match incoming payments to pending trades.
Admin Dashboard: Add live escrow tracking, an append-only event log, and manual override buttons (release/refund) to our Express web dashboard. Tech StackNode.js 18+ & node-telegram-bot-api PostgreSQL 14+ (writing clean migrations) tronweb & TronGrid REST API RequirementsStrong experience with Node.js backend systems and raw SQL queries.
Proven experience tracking/interacting with the TRON network or similar EVM chains. Security-first mindset regarding private key management and state machine idempotency. Please reply with your experience building Telegram bots or crypto escrow systems.
