Live data is offline

On October 28, 2026 the servers behind Kerne's live data went offline. The website and the app are now served as static pages, so anything that came from those servers is paused. The smart contracts on Base do not depend on those servers and are unaffected.

What is offline

Live APY figures and the APY API.
Other server APIs. They answer with an "offline" error rather than old numbers.
Honesty Index updates, the treasury service, and website forms.

Figures printed on static pages may be out of date. Anything you need to rely on, read from chain.

What still works

kUSD, skUSD and the PSM contracts on Base. kUSD can be redeemed for USDC on chain at any time, up to the USDC held in the PSM you redeem from.
The mint, redeem and stake screens on app.kerne.fi talk to the contracts directly through your wallet.
Signed reserve statements resumed on November 12, 2026 at /api/por/signed, signed every 15 minutes by a new dedicated attestation key, 0xfA066f9701b75A4c134893E6c44D4fe87D2C9453, which holds no funds.
Reserves can be checked on chain: the USDC balance of each PSM below against the kUSD total supply.

Redeem kUSD for USDC directly on Basescan

You do not need any Kerne website for this. You need a wallet on Base holding kUSD and a little ETH for gas.

Contract	Address
kUSD	`0x5C2EfdF0D8D286959b42308966bc2B97f5680AA3`
USDC on Base	`0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`
Mint PSM (live)	`0xaBDE1138aa1Ce88d1dF06422C0c3b05D70569803`
Prior mint PSM (redeem only)	`0x07eBb486e11BD217e6085eb5ab663e4517595993`
Legacy redeem PSM (redeem only)	`0xFf3025ec18e301855aB0f36Ec6ECa115a29A5Fbc`

Pick a PSM that holds enough USDC. Open the PSM's Basescan page and check its USDC balance. Each PSM pays out only up to the USDC it holds.
Approve. On the kUSD contract, open Contract, then Write Contract, connect your wallet, and call approve with spender set to that PSM's address and amount set to the kUSD you want to redeem in 18 decimals (100 kUSD is 100000000000000000000).
Redeem. On the PSM, open Contract, then Write Contract, and call swapKUSDForStable with stable set to the USDC address above and amount set to the same value. USDC arrives in your wallet less the redemption fee (10 to 5 bps, lower on bigger tickets).

Unstake skUSD

On skUSD 0x96F5102C15b839757f811A98CEc3725Ac21DfA14, call redeem with your share amount (skUSD uses 24 decimals; read your exact balance with balanceOf on the Read Contract tab), and receiver and owner set to your own address. You receive kUSD, which you can then redeem as above.
