How this is modeled

Sampled APYs use historical funding, with today’s staking input and strategy assumptions applied throughout. Each rate compounds until the next observation. This is a hypothetical comparison, not past skUSD performance. Source data and calculation.

kUSD backing

Markets crash. Every kUSD still has a dollar behind it.

Stake kUSD

Every kUSD is backed by a dollar of USDC, not by ETH, so ETH can fall 50% overnight and the backing does not move. The code is verified on Sourcify, and you can check the reserves yourself on chain, any time.

Live from Base

Three more things behind every kUSD

Verified source

The live mint PSM runs the source Hexens reviewed and is an exact match on Sourcify. kUSD and skUSD have partial source matches; kUSD predates the reviewed commit.

Depeg gate

Every mint and redeem on the live PSM checks Chainlink’s USDC/USD feed and reverts if USDC slips off its peg.

Two of three

Changing a PSM gate or who can mint kUSD waits 48 hours in a public timelock that only the 2 of 3 Safe can propose to. The emergency pause is the exception: the Safe can pull it at once.

Kerne row

Kerne’s own row sits on the board, read the same way as every other.

Ethena

sUSDe advertised 4.22% and realized 4.73% over 30 days. The advertised figure is its 30 day average.

Falcon

sUSDf advertised 4.60% and realized 4.69% over the same 30 days, read the same way.
