IOP | Swaylend audit contest

What IOP | Swaylend is
Swaylend is a lending platform on the Fuel network: suppliers earn passive income by providing liquidity, and borrowers post up to six collateral assets to draw USDC, the base asset.
The protocol reimagines the Compound architecture in the Sway language against the FuelVM's UTXO model, which is exactly where a line-by-line port can go wrong.
Scope
The Sway market contracts: collateral and base-asset accounting, absorption and liquidation, and the Pyth price feeds.
