Collateral and oracle exposure

Each token you're exposed to, and the market it backs. If that market breaks, this is how much the vault loses, in dollars and as a share of the vault. Open a row for the price feed, stress curve, and supply-cap detail. Below, the oracles those prices depend on and what is at stake if one is compromised.

Loss scenarios

Each row is a distinct failure, and every loss is a share of your deposit — the same percentage whatever you deposited. Loss is that share at a −30% collateral crash, the standard stress; Worst case is the ceiling if everything goes wrong, a conditional loss if it happens rather than a likelihood. Open a row for the loss at every crash depth, the dollar amounts, conditions, and the math.

Safety role, not an attack role: can revoke ANY pending timelocked curator change, instantly cut caps, and pull funds from adapters back to idle. Strictly risk-reducing — a captured sentinel cannot introduce new risk.

Allocators22 EOAsReaches deposit · instant

Moves funds between markets the curator has ALREADY approved — instantly, with NO timelock and no exit window. Cannot reach a brand-new market, but can concentrate you into an approved-but-stressed market or order withdrawals so you hit weak liquidity first.

Dependencies that can affect your deposit

10 things this pool relies on but doesn't control. Select one for its story.

Morpho Blue

oracles

Market Specific oracle

Every Morpho Blue market chooses an immutable oracle contract at creation; implementations can be Chainlink-like, exchange-rate, fixed-price, or custom. Failure modes: attacker-favourable price feed (covered in market-oracle-compromise) or price() revert / staleness blocking liquidations (covered in oracle-liveness-or-malfunction).

No quantified loss scenario references this dependency directly.
