hades-ps-sniper — 0xhades

Overview

hades-ps-sniper is a Rust-based trading bot that monitors pump.fun token graduations to the PumpSwap AMM in real time. The bot subscribes to PumpPortal's WebSocket migration feed, applies a battery of on-chain filters to each graduating token, waits a configurable pre-buy window with active rug detection, then executes buy and sell transactions with dynamic exit logic and Discord telemetry.

The architecture is designed for hands-off operation — automatic WebSocket reconnects with exponential backoff, slippage escalation on failed transactions, and three concurrent exit signals that compete for the trigger pull. It can run continuously without supervision.

Key Features

Real-time graduation monitoring via the PumpPortal WebSocket migration feed.
On-chain filtering — holder count, bonding-curve trade history, and top-holder concentration thresholds.
Pre-buy timer with integrated rug-pull detection during the wait window.
Automated buy/sell execution through PumpPortal with locally signed transactions and configurable slippage.
Three concurrent exit signals: hard stop-loss, hard take-profit, and dynamic multi-tier trailing stops (e.g. 12:7,20:10,40:10).
Direct PumpSwap pool price tracking — no third-party price feed dependency.
Optional Discord webhook notifications for entries, exits, and exceptional events.
Auto-reconnect with exponential backoff on WebSocket disconnects.

Requirements

Rust 1.85+ with edition 2024.
Solana mainnet RPC endpoint — a paid tier is strongly recommended for stable WebSocket connections under load.
PumpPortal account — free tier is sufficient. API key optional.
Funded Solana wallet (64-byte keypair JSON from solana-keygen).
Discord webhook URL (optional, for live notifications).

Setup

1. Clone and build

~/install

$ git clone https://github.com/hadesbaker/hades-ps-sniper.git
$ cd hades-ps-sniper
$ cp .env.example .env
$ cargo build --release

2. Configure your environment

Edit .env with your RPC endpoints, wallet keypair path, and (optional) Discord webhook URL. Edit config.toml to set your trade amount, slippage tolerance, priority fees, on-chain filter thresholds, and the trailing-stop tier string.

3. Run

~/run

$ cargo run --release
# or, with persistent logs:
$ cargo run --release 2>&1 | tee logs/run.log

Trailing-Stop Tiers

The multi-tier trailing stop is the bot's most distinctive exit mechanism. Each tier is defined as profit%:drawdown% — once a profit tier is hit, the trailing stop locks in that level and tightens the drawdown allowance. Tiers stack so the stop ratchets upward as a position works.

config.toml

# Example: ratchets profit to +12% / +20% / +40% milestones,
# with progressively tighter drawdown allowances at each.
trailing_tiers = "12:7,20:10,40:10"

This software moves real money. Newly graduated tokens are highly speculative. The bot takes full custody of the configured wallet and executes trades autonomously. The repository explicitly states this is provided for educational purposes with no warranty. Start with the smallest trade amount that exercises the codepath.
