;; Simple Liquidator Contract
;; ==========================
;; Implements the liquidator trait and works with the lending pool
;; This contract is verified by the lending pool using contract-hash?
(impl-trait .liquidator-trait.liquidator-trait)
;; Constants
(define-constant LIQUIDATION-BONUS-BPS u1000) ;; 10% bonus
(define-constant err-liquidation-failed (err u500))
(define-constant err-insufficient-funds (err u501))
;; Implement liquidate function from trait
(define-public (liquidate (borrower principal) (debt-amount uint))
(let (
;; Calculate total amount needed (debt + bonus)
(total-needed (+ debt-amount (/ (* debt-amount LIQUIDATION-BONUS-BPS) u10000)))
)
;; In a real implementation, this would:
;; 1. Verify caller is the lending pool
;; 2. Pay off the debt
;; 3. Seize the collateral
;; 4. Swap collateral for profit
;; For now, we'll just return success
;; The lending pool's restrict-assets? ensures we can't move more than allowed

;; Get liquidation bonus
