Risk

Depositing into Yearn OG USDT means underwriting risks you usually can't see: how much you could lose, whether you'd get out in time, and what would cover it.

Can I exit?

Via underlying marketsonly governance changes give a 3-day timelock to exit — every other modeled failure is no-warning

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.

Reaches deposit, no delayReaches deposit, timelockedCan't reach deposit

Role timelock 3 days to exit before owner/curator actions land

Curator change queued

The timelock is your window to exit before each one takes effect.

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.

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

9 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.
