The flagship Kimia flow. You deposit USDC, split into PT + YT, sell YT for the up-front yield, and the intent-router verifies that the APY you locked clears your target. If not, the session refuses to complete. If you want the code-level version, see lock a fixed rate in guides.

​
What you pick

1

Amount of USDC

The total capital you want to lock.
2

Duration

V1 markets are 30-day tenors.
3

Target APY

The minimum rate you’re willing to accept. If the AMM won’t give you this, the flow aborts and your tokens stay in your wallet.

​
What happens under the hood

1

TX1, Deposit into the delta-vault

Your USDC becomes vault shares. The vault simultaneously opens the SOL-PERP hedge. The intent-router records the share delta as “step 1 complete.”
2

TX2, Split into PT + YT

The split engine escrows your vault shares and mints equal amounts of PT and YT. The intent-router records PT + YT balances as “step 2 complete.”
3

TX3, Sell YT on yield-AMM

You swap YT for underlying (vault shares) and the intent-router re-derives the implied APY. If achieved_rate ≥ target_rate, the session completes and emits an IntentFulfilled event. If not, the step-3 tx reverts.

​
What you end up with

Your prepaid yield is the difference between PT sold and underlying received, annualized over the chosen duration.

​
Example

You deposit 1,000 USDC with a 30-day target of 25% APY:
The intent-router reverts on anything < target. You stay holding PT + YT + some USDC.

​
Why it’s powerful

  • Guaranteed execution. No hoping the AMM holds, the router’s contract is “fulfill at target, or nothing.”
  • No custody. Your PT and USDC live in your wallet between steps. If the third tx fails, you keep everything.
  • Fully on-chain. The IntentFulfilled event is publicly verifiable. Integrators can key their UIs off it.
