How Crypto-Backed Credit Lines Linked to Cards Work
Some products let you post crypto as collateral and receive a credit line that can be linked to a card. This page explains the mechanics — from loan-to-value and liquidations to fees and repayment — in neutral, documentation-style language.

“Crypto credit” usually refers to a credit line that is secured by digital assets instead of traditional collateral. The user deposits crypto with a platform, which assigns a borrowing limit based on the value of that collateral.
In some product designs, this credit line is connected to a payment card, so card spending is effectively financed against the crypto position rather than an unsecured revolving line in the usual sense.
Core Building Blocks of Crypto-Backed Credit
Although implementations vary, many crypto-backed credit products share the same structural components:
- Collateral deposit – you transfer supported tokens or coins to the provider or smart contract.
- Loan-to-value (LTV) – the maximum borrowing amount is a fraction of the collateral’s value.
- Margin thresholds – specific LTV levels may trigger warnings, margin calls or liquidations.
- Interest and fees – borrowing rates, origination fees and card-related fees are defined in schedules.
- Repayment rules – how and when outstanding balances must be repaid to restore collateral headroom.
When a card is attached, card transactions draw from the credit line, and repayments reduce that card-linked balance.
Liquidations, Volatility and Collateral Management
Because crypto prices can move quickly, platforms rely on automated rules to keep credit lines collateralized:
- Price feeds or oracles track the value of the collateral in near real time.
- If market moves push LTV above a threshold, the platform may require extra collateral or partial repayment.
- If no action is taken, some or all collateral can be sold to cover the outstanding balance and fees.
These mechanisms are described in platform documentation and can differ substantially between providers and jurisdictions.
How Crypto Credit Interacts With Card Usage
When a card is used on top of a crypto-backed line, several flows come together:
- Card transactions are authorized and settled through normal payment networks.
- The resulting debits increase the borrowed amount on the crypto credit line.
- Interest accrues on that borrowed amount, according to the specific pricing tables.
- Repayments, either in fiat or crypto, reduce the outstanding credit and may free up collateral.
In some setups, rewards or incentives may also be paid in tokens, which adds another layer of volatility and risk.
