Users can swap one collateral type for another within the FlyingTulip lending protocol. For example, swap USDC collateral to wS collateral (or any supported pair). The frontend signs an EIP-712 order and submits it to the executor API. The executor handles DEX routing and on-chain execution.

1. User has collateral deposited in PositionsManager (e.g., USDC)
2. User signs an EIP-712 swap order specifying sellToken → buyToken

The swapCollateralFlashWithSession function on the LeverageRfqEngine contract allows users to swap one collateral type for another within the FlyingTulip lending protocol (PositionsManager). The executor service acts as the filler, routing swaps through DEX aggregators (Odos) via a flash callback pattern.

User signs EIP-712 order → Executor API → Service picks up order

Returns FT token balance, puts/marketplace summary, and the 3 most recent user actions for the wallet widget.

No query parameters needed — aggregates across all chains automatically.

We replaced 6 legacy per-action hooks with a single consolidated useFTUSDActions hook. This mirrors the pattern used in lending (useLendingActions).

• useMintWithPermitAndFee — buy (mint) ftUSD
• useRedeemWithPermit — sell (redeem) ftUSD
• useStakeWithPermit — stake ftUSD to vault
