Backtest Results

Tested against 7 historical crypto crashes (LUNA, FTX, Celsius, 3AC, UST, SOL/FTX, TITAN) and 4 calm-market control periods. Full methodology and data: CryptoGuard backtest.

Method	Recall	Avg Lead Time	False Positive Rate
CryptoGuard (WaveGuard engine)	100% (7/7)	27.4 days	6.1%
Z-score baseline	100% (7/7)	28.4 days	29.9%
Rolling volatility	86% (6/7)	15.5 days	4.0%

5× fewer false alarms than statistical baselines with the same recall.

Example: FTX Collapse (November 2022)

On October 16, 2022, FTT was trading at $23.73. Z-score analysis saw nothing (score 1.20, PROCEED).

CryptoGuard flagged CAUTION (anomaly score 4.72). The next day it escalated to BLOCK.

23 days later, FTX collapsed. FTT fell 94%.

Install

pip install CryptoGuardClient

Quick Start

from cryptoguard import CryptoGuardClient

client = CryptoGuardClient()

# Validate a trade — primary use case
result = client.validate_trade("bitcoin", action="buy", amount_usd=1000)
print(result["verdict"])  # PROCEED / CAUTION / BLOCK

# Scan a token
scan = client.scan("solana")
print(scan["risk_level"])

# Rug pull check
rug = client.rug_check("solana", "0xabc123...")
print(rug["risk_score"])

# Check free tier remaining
print(client.free_tier())

Primary Endpoint

curl -X POST https://gpartin--cryptoguard-api-fastapi-app.modal.run/v1/validate-trade \
  -H "Content-Type: application/json" \
  -d '{"token": "solana", "action": "buy", "amount_usd": 500}'

First 5 calls/day are free. After that: $0.05/call via x402 USDC, or via RapidAPI.

How It Works

1. Resolves token input — CoinGecko ID, ticker symbol, or contract address (7 chains)
2. Fetches live market data from CoinGecko + DexScreener
3. Builds baseline from tier-matched peers (microcaps vs microcaps, large caps vs large caps)
4. Extracts 10 time-series features per day (price ratios, volume dynamics, momentum, volatility)
5. Runs anomaly detection — GPU-accelerated WaveGuard engine scores each token against its peer baseline
6. Multi-check pipeline: peer scan + rug pull + history + CEX/DEX spread + concentration risk
7. Returns verdict: PROCEED / CAUTION / BLOCK with anomaly scores and top contributing features

About the detection engine

CryptoGuard's core scanner is powered by WaveGuard, a general-purpose anomaly detection engine that uses GPU-accelerated wave simulations instead of machine learning. Your token's feature vector is encoded onto a 3D lattice and evolved through coupled wave equations. Normal data produces stable wave patterns; anomalous data produces divergent ones.

The advantage over statistical methods: WaveGuard captures non-linear interactions between features that simple threshold checks miss. This is why it flagged FTT 13 days before z-score analysis in backtesting.

No model training, no drift, no retraining. Deterministic for the same input.
