KAST’s Deposit Terms Draw Scrutiny After Public Feud With Ether.fi’s CEO

A public disagreement between ether.fi CEO Mike Silagadze and KAST CEO Raagulan Pathy has turned into a five-day scrutiny session over how KAST, a crypto-linked card and payments provider, handles customer deposits in its terms of service. According to The Defiant, the exchange began as a comparison of card fees between the two products before escalating into broader questions about custody language in KAST’s user agreement.

From fee comparison to custody question

The dispute reportedly started as a routine back-and-forth on X over which company’s card product offered better fee terms for users. Within days, the conversation shifted away from pricing and toward a more consequential issue for anyone holding funds on a crypto debit card: what happens to those deposits contractually once they sit with the issuer.

That pivot is the part traders and on-chain researchers should track. Fee disputes between competing card products are common and largely irrelevant to risk assessment. Disputes over deposit-handling language in a terms-of-service document are not — they go directly to whether user funds are treated as bailment, as a loan to the platform, or as something in between, which determines what happens to depositors if the issuer runs into liquidity trouble.

Why the fine print matters more than the feud

Public feuds between founders tend to generate headlines and fade quickly. What tends to persist is the underlying document that prompted the scrutiny in the first place. If KAST’s terms of service permit the company broad discretion over customer funds — commingling, rehypothecation, or discretionary use — that is a structural risk factor independent of who won the argument on social media.

For a card product that markets itself around crypto-native rails, the comparison to a DeFi restaking protocol like ether.fi is instructive. Restaking protocols are built around on-chain, verifiable custody logic that users can audit directly. A card issuer’s deposit terms, by contrast, sit in an off-chain legal document that most users never read closely — until a public dispute forces the comparison.

What traders should watch next

The Defiant’s reporting does not detail specific clauses in KAST’s terms, and no figures on deposit volumes, user counts, or fee percentages were disclosed in connection with the dispute. Until KAST or ether.fi publish more concrete detail — either a clarified terms-of-service excerpt from KAST or specific claims from Silagadze — the story remains a reputational flashpoint rather than a confirmed custody failure.

Still, the episode is a reminder that as crypto-linked card products scale, their legal terms around customer funds deserve the same scrutiny as smart-contract code in DeFi. Depositors and integrators evaluating KAST or comparable card issuers should read the deposit-handling clauses directly rather than relying on marketing claims about “crypto-native” custody.
