AUTONOMOUS RISK PROTECTION FOR DEFI LENDING

When DeFi breaks, Faultline moves first.

FAULTLINE maps the hidden dependencies behind a DeFi position, prices what a failure would cost you, and tells you whether to stay or exit. Countermove, in development, executes a defense you authorized in advance and records the proof.

The demo runs on recorded on-chain data. No wallet needed.

THE HIDDEN PROBLEM

One position. Five layers deep.

A Pendle PT on Morpho looks like one asset. It depends on a lending market, an AMM, an oracle, a yield issuer and a chain. A failure in any of them can reach you, and most of them never show up in your wallet.

FAULTLINE reads each layer on-chain, estimates how much of a failure would actually travel to the position, and compares that with what it costs to leave. Every figure carries its source and block.

01 / BEFORE THE CRISIS

Decide the defense before the crisis.

Choose which protective actions FAULTLINE may take, fund a restricted rescue reserve, and set hard limits. The RescueVault contract refuses anything outside them.

02 / DURING THE CRISIS

Detect the shock. Compare the moves. Act.

On a local fork, the weETH/ETH feed drops 9% and the position's LTV crosses its 82% trigger. Countermove scores every allowed action against a further 8% ETH drop, rejects what the reserve can't fund, and sends the smallest move that keeps a 250 USDC buffer.

Recorded fork scenario S1. The shock is simulated; no mainnet transaction was sent. Market LLTV 86%.

03 / AFTER THE CRISIS

Every move leaves a receipt.

After execution, FAULTLINE re-reads the position and records what was sent, why, and what changed, so anyone can check it.
