01The problem

When a pool breaks, the average user finds out too late.

By the time a human notices a depeg or a liquidity run, the liquidity has already evaporated and exit slippage has exploded. Panic-selling into a dead pool is how the losses actually happen — not the depeg itself. The market doesn't wait for you to read the chart.

02The mechanism

One index. One threshold. One automated exit.

01

Monitor

Umbra streams tick-level swaps, liquidity events and price from Uniswap v3 via The Graph — continuously, on-chain.

The Graph
02

Score

Three signals — liquidity flight, order-flow imbalance, price divergence — fuse into the CBRI (0–100) through a Noisy-OR model.

CBRI · 0G
03

Evacuate

The instant CBRI crosses the optimal threshold τ*, Umbra swaps your position into a safe stablecoin on Uniswap.

CBRI = 100 · (1 − ∏(1 − wᵢ·sᵢ))

A weighted Noisy-OR: any single signal spiking is enough to raise the alarm. Weights down-rank signals that aren't discriminative on a given crash — the model stays honest, not loud.

03The proof · backtest

Replayed on the real crash. Umbra exits at $1.0000 — the depeg bottomed at $0.873.

We replayed the USDC/SVB depeg candle-by-candle against real on-chain liquidity. The optimal threshold τ* isn't guessed — it's the point that maximises net funds saved with zero false alarms in calm markets. Umbra fires once, early, and gets out clean.
