The collateral is 12.55 mixWETH, shares in the mixWETH vault. At a share price of 1.007408 WETH they are worth 12.64 WETH, or $30.1K at WETH’s $2,380.1319.

A fall of 5.7% in the vault’s share price would take collateralisation from 111.6% to the liquidation line at 105.3%.

1.11 alETH of the debt is set aside for repayment. A line redemption clears it, and so does the holder repaying with vault shares or closing the position. At this share price clearing all of it takes 1.10 mixWETH from the collateral, plus 0.002745 mixWETH for the line’s 0.25% redemption fee.

Across the 75 line redemptions on the timeline below, the line cleared 1.18 alETH of this position’s debt and took 1.181 mixWETH of its collateral. Valued in WETH at each redemption’s block, with one alETH counted as one WETH, that is a net of −0.003 WETH for the holder: the debt cleared less the value of the collateral taken. The line’s 0.25% redemption fee, paid to Alchemix’s fee receiver, is −0.003 WETH of it (0.003 mixWETH). Each redemption’s own net is in its card’s detail.
