Anyone may call batchLiquidateTroves with Trove IDs; an ICR below the 110% MCR is immediately liquidatable. Debt is offset against the branch Stability Pool first and any remainder is redistributed with seized collateral to active Troves. · liquidation delay None
Branch Stability Pool 0x83e5BDe77d7477eCd972E338541b90Af57675536 absorbs debt first and permits just-in-time deposits; uncovered debt and collateral are redistributed to remaining active Troves. No external insurance or committed auction capital exists.
There is no alternate provider. The outer WETHPriceFeed uses a uint256.max staleness threshold for the block-timestamped nested conversion response; an invalid or reverting nested aggregator call is caught and, when adequate gas remains, irreversibly shuts the branch and returns lastGoodPrice rather than selecting another source.
Anyone can irreversibly shut the branch when TCR falls below 105%; required-oracle failure also invokes shutdown and freezes lastGoodPrice. Borrowing and interest stop while closing, liquidations, Stability Pool operations, and 2%-bonus urgent redemptions remain. The implementation has no final bad-debt cure, so debt can remain if collateral is exhausted.

Permissionless immediate batch liquidation below 110% MCR; branch Stability Pool offset precedes redistribution to remaining Troves. · liquidation delay None
Branch Stability Pool 0xd48dC7cDdc481F596BD9A97755c7Ac696aD4eA87 accepts normal or JIT deposits; uncovered debt is redistributed to active Troves, with no external insurance or auction backstop.
If the primary answer is non-positive or at least 172800 seconds old, the custom oracle selects its enabled Curve fallback, whose timestamp is block.timestamp. If the required share-rate or selected custom oracle path reverts or the outer 172800-second validation fails, the branch irreversibly shuts down and thereafter serves lastGoodPrice.
TCR below 105% or unrecoverable required-price failure irreversibly freezes the branch onto lastGoodPrice; interest and borrowing stop, while closing, liquidation, SP operations, and urgent redemption remain. Residual unbacked debt has no automatic cure.

FALLBACK_ORACLE was zero. A non-positive or at least 172800-second-old Chainlink answer becomes invalid; required-call failure, share-rate failure, or invalid outer response shuts the branch and switches to lastGoodPrice rather than another provider.
TCR below 105% or oracle failure irreversibly shuts the branch onto lastGoodPrice; urgent redemption remains but no automatic mechanism cures residual debt after collateral exhaustion.

The WBTC/BTC leg is invalid after 172800 seconds and BTC/USD after 86400 seconds; either invalidates the composite and selects the enabled Curve fallback.
