solars

A high-frequency off-chain copy-trading bot for Solana. Monitors a target wallet in real-time and replicates its trades with sub-second latency.

How It Works

1. Detect — Subscribes to the target wallet via Helius WebSocket (logSubscribe) to catch transactions the moment they hit the mempool.
2. Confirm — Uses signatureSubscribe to track confirmation status without polling.
3. Execute — Fetches and decodes the transaction (get_transaction), then routes a mirrored trade through PumpPortal, Bags.fm, or Jupiter as a fallback.
4. Submit — Sends the final transaction via Helius Sender with a Jito tip for priority landing.

Configuration (config.json)

Field	Description
rpc_url	Helius HTTPS RPC endpoint
helius_wss_url	Helius WebSocket endpoint
bags_fm_api_key	Bags.fm routing API key
jupiter_api_key	Jupiter aggregator API key
wallet_addr	Your public key
wallet_key	Your private key
target_addr	Wallet address to copy
scalar	Trade size multiplier
max	Maximum trade size cap (lamports)
signatures	Signatures to copy (for testing)

Performance (dependent on internet speeds)

• Detection latency: ~49–59ms
• End-to-end execution: ~550–867ms (depending on routing and pressure).

Stack

• Rust + Tokio async runtime
• Helius — RPC, WebSockets, and transaction sender
• PumpPortal / Bags.fm — Prebuilt transaction routing
• Jupiter — Fallback DEX aggregator for sells
• Jito — MEV-aware transaction landing (min tip: 0.0002 SOL)
