How fast can I get back to USDC?
Redeem kUSD for USDC in one transaction, up to the USDC held in the PSM you redeem from (read live). There is no lockup and no cooldown.
What backs kUSD?

Do I have to trust Kerne to use the paid products?

How do I pay for verification?
In USDC on Base, and a company can ask for an invoice for any fixed price service above $149. The cheapest paid item is the $29 instant signed read, and Verify Any Stablecoin is free.
