The crypto-to-fiat payment platform KAST has come under intense scrutiny following revelations regarding its user agreement and asset handling policies. Mike Silagadze, the CEO of liquid staking protocol ether.fi, publicly questioned the legal structure of the service, highlighting clauses that may strip users of their property rights upon depositing funds. This development has ignited a broader debate within the DeFi and crypto card industry regarding the transparency of custodial payment solutions and the legal definition of digital wallet balances.
Ownership Rights and Asset Reclassification
The primary controversy centers on specific language within the KAST terms of service, which defines the transfer of cryptocurrency or stablecoins to the platform as a final sale to the company. According to the document, once a transaction is processed, the user no longer retains legal ownership of the underlying virtual assets. Instead, the interface displays a ledger record denominated in US dollars, which serves as a representation of credit rather than a traditional account balance.
- Users relinquish ownership of digital assets upon transfer to the KAST platform.
- The app display is characterized as a ledger record, not a deposit or stored value currency.
- KAST explicitly states it is not a banking institution and offers no deposit insurance protections.
This legal structure is significantly different from non-custodial wallets where users maintain control of their private keys and, by extension, their property.
Competitive Tension in the Crypto Card Market
The critique from Mike Silagadze arrives as ether.fi Cash competes directly with KAST in the burgeoning market for crypto-linked debit cards and stablecoin payment systems. By drawing attention to these terms, Silagadze highlights a critical risk factor for consumers who may assume their digital assets are held in escrow or a protected account.
When you send crypto to KAST, you are selling it to them. You no longer own it. What you see in the app is just a number on a screen, not your money.
The lack of regulatory safeguards such as FDIC insurance in the United States or similar schemes in other jurisdictions means that in the event of insolvency, users would be classified as unsecured creditors.
The situation surrounding KAST serves as a reminder for market participants to conduct thorough due diligence on service providers in the blockchain ecosystem. As the industry moves toward July 2026 and faces increasing regulatory oversight, the distinction between true asset ownership and mere ledger entries remains a pivotal issue for both institutional and retail investors. Users are advised to review the specific legal frameworks of payment platforms to ensure their financial expectations align with the contractual realities of the services they utilize.
