There was a problem hiding this comment. No check for liquidation eligibility. The button is rendered for all borrowers regardless of whether they're actually liquidatable (LTV > LLTV). Attempting to liquidate a healthy position will fail on-chain. Consider disabling the button or checking eligibility: Suggested approach export function LiquidateButton({ market, borrower, onSuccess }: LiquidateButtonProps) {
+ const maxLtv = Number(market.lltv) / 1e18;
+ const isLiquidatable = borrower.ltv > maxLtv * 100;
+
// Seize all collateral - Morpho will calculate the appropriate repayment
const seizedAssets = BigInt(borrower.collateral);
// ... hook call ...
return (
<Button
variant="ghost"
size="sm"
className="h-7 px-2 text-xs"
onClick={handleClick}
- disabled={isLoading}
+ disabled={isLoading || !isLiquidatable}
>
- {isLoading ? 'Processing...' : 'Liquidate'}
+ {isLoading ? 'Processing...' : isLiquidatable ? 'Liquidate' : 'Healthy'}
</Button>
);
