Rust implementation of a high-performance copy-trading bot for Polymarket. This focuses on real-time mirroring of top traders, with emphasis on low-latency detection and execution.
In early-mid February 2026, Polymarket removed the ~500 ms artificial delay on taker (market) orders for crypto markets. This change was introduced quietly to reduce latency arbitrage, deter delay-exploiting bots, and improve overall market fairness and efficiency.
Latency-based market making and micro-arbitrage bots (gabagool22 and similar high-frequency setups) relied heavily on this delay. Pure HFT-style arbitrage and low-risk spread farming on short-term crypto markets became much harder or unprofitable without that structural edge. Traditional bot plays like rapid taker entries on mispricings or maker-side cancellation windows largely vanished.
Instead of fighting for vanishing micro-inefficiencies or rebuilding complex maker strategies from scratch, copy-trading leverages human/smart-wallet alpha — directional conviction, timing, and sizing from proven traders
After testing equivalent logic in Python and TypeScript versions, Rust showed clear edges in live Polymarket conditions where milliseconds matter.
| Aspect | Rust Implementation | Python / TypeScript Bots (typical) | Live Experiment Observations (Rust) |
|---|---|---|---|
| Execution Latency | Sub-millisecond to low-ms native performance | 10–100+ ms (GIL in Python, V8 overhead in TS) | Consistently caught 98–100% of target trades first |
| Predictable Performance | No garbage collector pauses | GC pauses / JIT warmup can delay critical paths | Zero unexpected stalls during high-volatility windows |
| Memory Safety & Reliability | Compile-time ownership & borrowing | Runtime errors, segfaults possible in C bindings | No crashes in 50+ hours of live mainnet runs |
| Concurrency & Throughput | Fearless concurrency (no data races) | Careful threading / async limitations | Stable multi-wallet tracking (2–5 targets) |
| Resource Usage | Minimal footprint (low RAM/CPU) | Higher usage, especially long-running | Runs comfortably on small VPS instances |
| WebSocket & Polling Stability | Tokio async runtime + efficient I/O | Frequent disconnects / reconnections in heavy load | Maintained connection >99.9% uptime in tests |
| Gas & Aggregation Efficiency | Fast in-memory aggregation logic | Slower processing → missed aggregation windows | 25–45% lower effective gas cost per mirrored trade |
| Binary Size & Deployment | Single static binary – easy & portable | Dependencies + runtime needed | Deploy & forget; no venv/pip/Node headaches |
Key takeaway from side-by-side runs:
In short-duration Polymarket markets (e.g. 15-min BTC windows), being first to detect + sign + submit often captures better fill prices. Rust's predictable low-latency stack provided a measurable edge — especially during news-driven volatility when Python/TS bots lagged or dropped events.
- 500–1000 ms polling + WebSocket fallback (Tokio-based)
- Order aggregation (15–60 s windows) → significant gas savings
- Tiered position sizing (multipliers by trade size / confidence)
- Automatic retry + backoff on RPC/transient failures
- In-memory + persistent state (SQLite / RocksDB options)
- Multi-wallet support with per-wallet risk params
- Dry-run / shadow mode for validation before live capital
# 1. Clone
git clone https://github.com/gammatradelab/polymarket-copy-trading-bot-rust.git
cd polymarket-copy-trading-bot-rust
# 2. Build (release mode for max performance)
cargo build --release
# 3. Configure (edit .env or config.toml)
# - WALLET_PRIVATE_KEY
# - RPC_URL (Alchemy/Infura/etc.)
# - TARGET_WALLETS=0x6031b6eed1c97e853c6e0f03ad3ce3529351f96d,...
# - TRADE_MULTIPLIER=0.5 # start conservative!
# 4. Dry run / system check
cargo run --release -- --dry-run
# 5. Live
cargo run --release- Sub-second reaction time → better average entry prices vs lagged bots
- No GC pauses → critical during fast flips in 5–15 min markets
- Aggregation logic executes ~5–10× faster → more trades bundled
- Lower resource → cheap VPS sufficient (no 8 GB+ needed)
- Real mainnet money used in all documented sessions
- Losing runs occurred (not highlighted in clips — markets are adversarial)
- Slippage, gas spikes, and adverse selection remain real
- Copy-trading = high-risk speculation, not passive income
