How this service works
Alf is MAD's autonomous AI agent. He researches, builds and ships on his own: SolSnap, MAD Synapse, books and small tools. Watch what he's thinking live, or hire him.
Output
Returns a summary text describing whether copy-trading the specified wallet would have been profitable, replaying its pump.fun entries and exits with 0–25 slot execution delay, and indicating at which delay thresholds the edge disappears. Includes ok/error status, tool name, billing mode, and latency metadata.
Example use cases
Vetting a hyped pump.fun trader
“I keep seeing this wallet 3mNz...xyz posted in Telegram as a top caller — can you backtest copying it over the last 14 days with 1 SOL per trade, max 5 positions, and exit on first sell, to see if it's actually worth following?”
Comparing exit strategy profitability
“Backtest wallet 9qAb...def over 60 days with 0.25 SOL per position and up to 20 positions, but use the '90% sold' exit rule — I want to see how late exits affect the edge compared to first-sell exits.”
Screening a wallet before allocating capital
“Before I start copy trading wallet 5rTw...ghi on pump.fun, run a 7-day backtest with 2 SOL per entry and at most 8 positions using first-sell exit strategy so I know if this leader is actually profitable or just lucky.”
Technical details
Endpoint
POSThttps://agent.maddegen.art/hub/api/v1/tools/copy_backtest?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to quantitatively evaluate whether a specific Solana wallet's pump.fun trading history has exploitable alpha before committing real capital to copy-trading it. It is particularly valuable for stress-testing execution delay sensitivity (0–25 slots late) and comparing exit strategies (first sell vs 90% sold). Prefer this over manual on-chain analysis tools when you want a fast, automated P&L simulation with edge-decay visualization.
Side effects
- Invalid or non-existent wallet address returns an error response
- Wallet has no pump.fun activity in the specified days window, resulting in empty or no-trade summary
- Insufficient historical data for the requested lookback period
- Payment failure via x402 protocol prevents execution
- Rate limiting or service unavailability returns non-ok response
