Question 1

What was the initial collateral mechanism for minting USP?

Accepted Answer

In the initial design, users could collateralize LP tokens from the Platypus Main Pool to mint USP. This used an existing liquidity position to support borrowing; it was not a process of depositing U.S. dollars with an issuer and receiving an equal amount of tokens.

Question 2

Could LP tokens still be used for farming after minting USP?

Accepted Answer

Under the original design, those LP tokens could continue to participate in Platypus liquidity-pool farming while the user also held the minted USP. Running both in parallel was intended to improve capital efficiency, not to promise a fixed return.

Question 3

What metric was USP's borrowing rate linked to?

Accepted Answer

The original mechanism tied the additional borrowing rate to USP coverage in the Main Pool. Borrowing cost was therefore designed not as a permanently fixed number, but as something related to the pool's coverage condition.

Question 4

Which mechanisms were originally intended to maintain USP's U.S.-dollar peg?

Accepted Answer

The original design combined Platypus's stablecoin-swap AMM algorithm with an interest-rate model, while treating balance-sheet solvency as a key condition. These were peg-maintenance mechanisms; they did not mean the market price was guaranteed to remain at its target.

Question 5

Did every collateral token use the same collateral factor?

Accepted Answer

No. The original design set different collateral factors for different tokens, so the collateral parameter for one token could not simply be applied to another.

Question 6

Could the original USP liquidation route only return USP?

Accepted Answer

No. The original route allowed collateral to be liquidated into stablecoins other than USP. This describes a collateral-liquidation path, not a promise that a holder could directly redeem USP for U.S. dollars from an issuer.

Question 7

What did the announcement mean by “up to 20x”?

Accepted Answer

The 2022 material described leverage farming of up to 20x through repeated USP minting. It referred to the leverage of a capital position, not a 20-fold return, and not an outcome every participant would necessarily achieve.

Question 8

Was minting with Alternative Pools LPs completed then, or planned as an expansion?

Accepted Answer

The 2022 announcement identified Main Pool LPs as the initial minting source and described minting with Alternative Pools LPs as a later expansion plan. That announcement alone is therefore not evidence that the expansion had already been completed.

Question 9

Did USP-related protocol-fee income automatically belong to USP holders?

Accepted Answer

The 2022 official explanation attributed an additional protocol-fee revenue source to vePTP holders, conditional on protocol-fee distribution going live. It did not grant that entitlement to all USP holders, nor establish that fee distribution was live at that time.

Question 10

How did the historical emergencyWithdraw call check a USP borrowing position’s solvency?

Accepted Answer

In the historical emergencyWithdraw call, _open=true, so the check compared the user’s debt with the USP borrow limit. The solvency Boolean was true when debt was less than or equal to that limit. Passing this check did not mean the debt had been repaid; this describes that call, not every solvency-check path.

Question 11

How did the February 2023 incident leave USP debt without collateral support?

Accepted Answer

A logic flaw at the time allowed users to withdraw collateral without repaying USP previously borrowed against it. The collateral was removed while the borrowing debt remained, leaving debt without the corresponding collateral support.

Question 12

Did USP's historical performance always meet its U.S.-dollar peg target?

Accepted Answer

No. An incident analysis published on March 10, 2023 recorded that USP had de-pegged from the U.S. dollar and that platform operations were paused when the article was written. This is a record from a specific historical point, not proof that the peg was always achieved or that the pause was permanent.
