Crypto cards aren't the future, but onchain credit is

Crypto cards, while a familiar interface for spending digital assets, are a temporary solution that will likely become obsolete as blockchain-native payment systems mature. Current crypto cards often require users to liquidate their holdings into fiat currency to make purchases, a process that halts yield generation and triggers taxable events. This approach, according to Vikram Arun, co-founder and CEO of Superform, represents a step backward, essentially creating a debit card with extra complexity rather than true innovation.

The Limitations of Current Crypto Cards

The primary issue with existing crypto cards is their reliance on traditional financial infrastructure. They necessitate the conversion of cryptocurrency to fiat, forcing users into a trade-off between liquidity and ownership. This conversion is treated as a taxable disposal by tax authorities like the IRS, leading to capital gains reporting for every transaction. Furthermore, card issuers typically profit from interchange fees, highlighting the underlying dependencies on legacy systems despite a decentralized appearance.

Onchain Credit as a Superior Alternative

Onchain credit offers a more innovative approach by allowing users to deposit yield-bearing assets and open a credit line against them. This model enables spending without liquidating assets, meaning collateral continues to earn yield while the user's debt increases. Assets are only sold if the debt falls below predefined risk parameters, triggering a transparent and deterministic liquidation process. This contrasts sharply with current systems where spending halts asset growth and creates idle balances.

Yield-bearing stablecoins currently offer yields around 5%, with other DeFi protocols ranging from 5% to 12%. In the onchain credit model, users can maintain spending power while their collateral continues to compound, avoiding forced conversions and idle balances.

Expanding Collateral Possibilities

The shift to onchain credit broadens the definition of eligible collateral. Instead of assets needing to be instantly liquidatable into cash, the focus shifts to assets that can be continuously priced and risk-bounded. This opens the door for a wider range of assets, including vault shares, Treasury-backed assets, and strategy positions, to serve as collateral. These assets remain productive until liquidation is necessary, allowing users to benefit from both yield and spending power without compromise.

The Card as a Thin Interface

The article emphasizes that the card itself is merely a consumer-facing compatibility layer, not the core product. The true innovation lies in the onchain credit line, which enables real-time authorization of spending based on a user's onchain balance sheet. This logic, when residing onchain, makes interfaces like cards optional and interchangeable, allowing for programmatic payments via APIs as well. If credit logic remains embedded within the card, users are confined to legacy payment rails and fee structures.

Transparent Risk Management

Onchain credit systems manage risk through transparency. Governance protocols set conservative loan-to-value ratios and ensure continuous pricing and transparent liquidation triggers. This approach contrasts with traditional credit systems that often obscure risk through hidden fees and complex terms. In the onchain model, risk parameters are set by the community through governance, offering a more explicit and auditable system for managing collateral volatility.

The Future of Payments

Crypto cards are seen as a bridge to a future where spending is seamless and integrated with blockchain technology. As wallets and crypto-native payment systems evolve, the need for traditional intermediaries like banks, issuers, and card networks will diminish. Onchain credit, enabling spending without selling and keeping assets productive, is positioned as the enduring system, with cards and other interfaces adapting to this underlying primitive.
