An automatic safety switch for your crypto. The moment a crash begins, Umbra moves your money to safety.
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.
Umbra streams tick-level swaps, liquidity events and price from Uniswap v3 via The Graph — continuously, on-chain.
Three signals — liquidity flight, order-flow imbalance, price divergence — fuse into the CBRI (0–100) through a Noisy-OR model.
The instant CBRI crosses the optimal threshold τ*, Umbra swaps your position into a safe stablecoin on Uniswap.
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.
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.
Tick-level Uniswap v3 history & real-time — swaps, liquidity, price.
Decentralised storage & traceability of the risk model and CBRI scores.
On-chain swap execution of the emergency evacuation into a safe stablecoin.
Watch the risk index climb from calm to critical — and Umbra pull the funds out at the exact right second.
