w4rn (reads 'warn') is a macro risk cockpit for crypto: calibrated drawdown and volatility-regime forecasts across 25 assets, the macro backdrop that drives them, and a plain-language Learn layer. It warns you about risk before it hits — a risk-awareness tool for people new to crypto, not a trading signal.
Free to start · no card · built on free & open data
A calibrated forecast, the macro backdrop that drives it, alerts, and a Learn layer — all in one cockpit, all explained in plain language.
A probability the asset has a sharp down-day, and whether the next 5 trading days are likely to be more volatile than its past 20 days — cross-validated and Platt-calibrated, with the out-of-sample AUC shown next to every number.
SOL, BTC, ETH and 22 more liquid coins — switch the anchor and the candles, forecast and risk synthesis all re-point to that asset.
Credit spreads, the dollar, rates, funding, the Fear & Greed index and dozens more series — each with a plain-language note on what it means for crypto and how much it actually predicts.
A built-in education layer — AUC, calibration, lead/lag, base rates — in beginner and pro modes, with live examples from the current market.
Link Telegram and get a message when the model flags a regime flip or a rising drawdown probability — no need to sit and watch the screen.
A risk gauge, not a money printer. We show where the model has skill and where it doesn't, and never dress a co-movement up as a prediction.
One fair annual price — no monthly churn. We can't out-price the institutions, and our data is built on free + open sources, so Pro is priced to be useful for years, not to nickel-and-dime you.

A few of the most common ones — we keep a full, searchable list in the Help & FAQ.
No. w4rn is a risk-awareness and education tool. Our own walk-forward backtest found the forecast is a risk gauge, not a tradeable signal — it tells you when to brace and size down, not what to buy. Nothing here is financial advice.
Free and open sources only — public market data plus open macro series (credit, rates, the dollar, funding, sentiment). No paid feeds are required for the core read.
No. You can read the market model with a normal account. A wallet only matters if you later choose to pay for a paid tier in crypto.
We publish the out-of-sample AUC next to every forecast. The volatility-regime read is the strongest (AUC around 0.6 to 0.7 across assets, where 0.50 = coin flip and 1.00 = perfect); the drawdown read is weaker and we say so. Magnitude is more forecastable than direction — and direction mostly isn't.
