Ultra-Speed Polymarket Copy-Trading Bot Development

Project: Build Ultra–Low Latency Polymarket Copy-Trading Bot (1–3 sec latency)

Objective

I need an experienced developer to build a fast, reliable, and low-latency Polymarket copy-trading bot.
It must detect trades from specific wallet addresses and instantly reproduce (copy) those trades from my proxy wallet with minimal delay.
Requirements

1) Core Features

Monitor 1–10 target Polymarket wallet addresses

Detect trades through Polymarket CLOB WebSocket in real time

Parse trade events: marketId, side (buy/sell), price, size

Copy the same trade on my proxy wallet with:

Proportional sizing (e.g., 50%, 100%, custom multiplier)

Min/max limits

Error handling for low balance


Avoid using Telegram bot in the core pipeline (UI optional)


2) Performance

End-to-end latency target: 1.5–3.0 seconds

Use:

WebSocket (NO polling)

High-speed RPC (QuickNode/Alchemy)

In-memory processing (NO MongoDB in hot path)

Efficient nonce & gas management


Log detection time, submission time, confirmation time


3) Backend Requirements

Node.js, Go, or Rust (preferred for speed)

Use Polymarket CLOB API / Smart Contract correctly

Use ethers.js or equivalent high-performance library

Private key must remain local (NO sending keys to remote API)


4) Extra Features

Config file for:

Target wallets

Sizing percentage

RPC URL

Gas settings

Min trade size


Dry-run / simulation mode

Automatic retry on failed order

Graceful reconnect for WebSocket


5) Deliverables

Full source code

Setup guide (how to run locally)

Config file + environment samples

Script to start/stop bot

Latency test logs

7-day support after delivery
