uUSD / XTZ V1 legacy debt
XTZ · max LTV 33.33% · MCR 200% · Official legacy collateral documentation and the pinned SDK record a 300% target ratio and 200% emergency/liquidation ratio. Finalized engine debt was 2,277.641100920260 uUSD.
Any caller may burn uUSD against a vault below the 200% emergency ratio and receive XTZ at the legacy liquidation payout; execution is atomic. · liquidation delay None
No funded liquidation backstop is active. The legacy bailout/minter-conversion feature was a holder conversion right, not bad-debt insurance, and Youves now labels it inactive.
The engine has one configured target-price oracle and no automatic secondary. Every composite component must return or the transaction fails closed, but millisecond report timestamps are compared with Tezos seconds and therefore make the nominal 900-second freshness check effectively unbounded.
No active shutdown or deficit-redistribution module is documented. Liquidation depends on a caller supplying uUSD; debt that cannot be economically liquidated remains with its vault rather than moving to a Stability Pool.
uUSD / tzBTC V2 legacy debt
tzBTC · max LTV 33.33% · MCR 200% · Legacy docs and SDK record a 300% target and 200% emergency ratio. Finalized engine debt was 77.881302640981 uUSD.
Any caller may burn uUSD against a vault below the 200% emergency ratio and receive tzBTC at the legacy liquidation payout; execution is atomic. · liquidation delay None
No Stability Pool, insurance reserve, or debt auction is connected to this engine; the legacy tzBTC branch is excluded from the now-inactive bailout conversion feature.
The finalized engine storage names one target-price oracle and no automatic secondary. Every composite leg must return or the transaction fails closed, but millisecond report timestamps are compared with Tezos seconds and therefore make the nominal 900-second freshness check effectively unbounded.
No active shutdown or deficit redistribution is documented. Liquidation requires caller-supplied uUSD, and unrecovered debt remains vault-local rather than being socialized.
uUSD / SIRS V2 legacy debt
SIRS (XTZ/tzBTC LP) · max LTV 33.33% · MCR 200% · Legacy docs and SDK record a 300% target and 200% emergency ratio. Finalized engine debt was 9,235.129323262868 uUSD.
The branch is designed for permissionless atomic liquidation below the 200% emergency ratio, but liquidation was unavailable at level 14059094 because the mandatory BTC/USD leg reverted PRICE_TOO_OLD after 301 stale epochs. · liquidation delay None
No Stability Pool, insurance reserve, or debt auction is connected to this engine; Youves explicitly excludes SIRS from the obsolete bailout conversion feature.
The engine has one custom target-price oracle and no alternate route; the LP callback value is transaction scratch, not a durable cached fallback. At the fixed level, generic BTC/USD last_epoch 1981969 was 301 epochs behind current epoch 1982270 and exceeded the four-epoch window, so PRICE_TOO_OLD made price-dependent mint, withdrawal, and liquidation actions unavailable.
No active shutdown or deficit redistribution is documented. Liquidation requires caller-supplied uUSD, and unrecovered debt remains vault-local rather than being socialized.
uUSD / USDt V3
USDt (Tezos) · max LTV 90.91% · MCR 110% · Finalized storage records collateral_ratio 110%, which base_tracker_engine_v3 enforces on mint and withdrawal and implies 90.909091% maximum LTV; settlement_ratio is the 115% holder-conversion term, not a liquidation threshold. Debt was 11,172,864.355705194083 uUSD.
Permissionless atomic liquidation burns caller-supplied uUSD and transfers USDt; payout is capped by the lower of the vault ratio and the configured 110% payout. · liquidation delay None
No funded liquidation backstop is connected to V3. Youves states V3 savings pools no longer support the bailout/minter-conversion feature.
The composite has no alternate feed and all required calls must return or INVALID_VIEW fails closed. Its nominal 900-second check compares millisecond report timestamps with Tezos seconds, making freshness effectively unbounded rather than contract-enforced.
There is no active Stability Mechanism or shutdown redistribution. An insolvent vault can be liquidated at its actual collateral ratio only when a caller supplies uUSD; otherwise debt remains vault-local.
uUSD / tzBTC V3
tzBTC · max LTV 74.07% · MCR 135% · Finalized storage records collateral_ratio 135%, which base_tracker_engine_v3 enforces on mint and withdrawal and implies 74.074074% maximum LTV; settlement_ratio is the 200% holder-conversion term, not a liquidation threshold. Debt was 34,382.971921254689 uUSD.
Permissionless atomic liquidation burns caller-supplied uUSD and transfers tzBTC; payout is capped by actual vault collateralization or the configured 112.5% payout. · liquidation delay None
No Stability Pool, insurance reserve, or debt auction funds V3 liquidation; the V3 bailout conversion feature is inactive.
Both legs must return and no alternate feed is selected; unavailable calls fail closed. Millisecond report timestamps are compared with Tezos seconds, making the nominal 900-second freshness check effectively unbounded.
There is no active Stability Mechanism or shutdown redistribution. An insolvent vault is resolved only through caller-funded uUSD burning at its actual collateral ratio; otherwise debt remains vault-local.
uUSD / XTZ V3
