When your Loan-to-Value (LTV) rises above the margin call threshold, you’ll receive a margin call from Arch. This means your collateral value has fallen relative to your loan balance, and you need to take action to bring your LTV back down to the starting LTV for your asset.
This guide explains what your options are in this scenario, and step-by-step instructions on how to cure it.
Navigate to your loan dashboard for the loan you have been margin called for and click the "how to cure my margin call button". There you will see a calculator that displays the exact amounts for either topping up collateral, making an additional payment, or requesting a partial liquidation.
You have three options to cure your margin call:
Option 1 - Add More Collateral
Deposit additional BTC, ETH, or SOL to reduce your LTV. This is the fastest and most common method. Refer to the calculator by clicking "how to cure my margin call", to see exactly how much you need to deposit to reach the cure threshold.
Steps:
Log in to your Arch dashboard.
Go to the loan dashboard for the loan in margin call.
Click Add More Collateral.
Choose the asset you want to deposit.
Send the required amount to the provided address.
The dashboard will automatically update your LTV once the deposit clears on-chain.
Option 2 - Repay Part of Your Loan Principal
Send a partial repayment to reduce your outstanding principal. Refer to the calculator by clicking "how to cure my margin call", to see exactly what payment is needed to reach the cure threshold.
Steps:
Log in to your Arch dashboard.
Open the affected loan.
Click Make a Payment.
Choose your payment method:
USDC (fastest)
Wire transfer
ACH
Pay the amount required to return your LTV to the starting level.
Your LTV will update automatically once the payment settles.
Option 3 - Request Arch Partially Liquidate your Collateral
If you prefer not to add collateral or repay, you may request that Arch perform a partial liquidation to restore your LTV. Refer to the calculator by clicking "how to cure my margin call", to see exactly how much Arch would sell in order to bring you to the cure threshold.
How to request it:
Email [email protected] with the subject line: “Liquidation Request – [Your Loan ID]”. Note: Liquidation requests must be sent to the support email, and cannot be processed via the chat.
State that you would like Arch to perform a partial (or full) liquidation to cure your margin call.
Once executed, your dashboard will show the updated LTV and loan balance.
Important:
A 2% partial liquidation fee applies, and the liquidation amount will be calculated to restore your LTV to the starting level for your asset.
Arch aims to respond to liquidation requests as fast as possible during business hours. Outside of business hours our standard SLA is within 24 hours.
We do not have the ability to set limit orders or guarantee execution prices
