Yield & APY

While your USDC is locked, it isn’t idle — it’s deposited into Kamino Finance , an established Solana lending protocol, where it earns lending yield in the main USDC market.

How it works

You lock USDC → the program’s vault deposits it into Kamino’s USDC reserve.
While you learn, the position accrues lending yield continuously.
When you claim, the position is redeemed. Everything above your principal is the gross yield, which is split at settlement:


gross yield = redeemed amount − your principal
fee         = 0% of gross yield        (beta; hard on-chain max 20%)
your share  = (gross yield − fee) × your yield percentage (100/50/0%)
pot share   = whatever remains

Your yield percentage is set by your Lapse count — see Lapses & your yield.

What APY should you expect?

The APY shown in the app is Kamino’s live USDC lending rate — it’s read from the market, and it moves with the market.

Yield is not guaranteed. Lending rates float continuously; the rate you see when you lock is not a promise of the rate over your whole course. Locked In does not set, boost, or guarantee any APY. In an extreme scenario the strategy can even lose value — see Risks for what that means for you.

Fees

Locked In’s platform fee on yield is currently 0%. The program allows a fee of at most 20% of gross yield (never principal) — hard-capped on-chain, so a fee above that is impossible without a program change you’d be able to see. If we introduce a fee, it will be announced and visible before it applies to new locks.
