Ether.fi’s CASH card, a Visa-linked product that lets users spend directly from their crypto vaults, has crossed $800 million in cumulative spend as of early September 2026. The kicker: roughly $600 million of that total was racked up this year.
The numbers behind the surge
Q1 2026 alone saw $170 million in spend volume, a 35% jump from the previous quarter. By late April, cumulative spending had already cleared $400 million, with monthly volumes regularly topping $50 million even during choppy market conditions.
By early September, the CASH product had processed nearly 10 million transactions. Perhaps more telling than the raw volume is the average transaction size: below $100. That pattern suggests users aren’t making a handful of large purchases to game cashback rewards. They’re buying coffee, paying subscriptions, covering everyday expenses.
The platform currently supports approximately 70,000 active cards and around 300,000 accounts, numbers that grew meaningfully after Ether.fi migrated the CASH product to Optimism’s OP Mainnet in February 2026.
CASH also offers up to 3% cashback on transactions, credited directly back to user vaults.
A revenue engine, not just a feature
In Q1 2026, CASH accounted for 26% of Ether.fi’s total revenue, nearly doubling its share from 14.2% in Q4 2025. That revenue comes from a mix of interchange fees, foreign exchange activity, and lending operations tied to the card’s underlying mechanics.
Why this model is different
Crypto debit and credit cards aren’t new. Coinbase, Crypto.com, and others have offered them for years. The difference with Ether.fi’s CASH product is the non-custodial structure. Users aren’t depositing funds with a centralized entity that issues a card. They’re spending from self-custodied vaults, meaning the protocol never takes possession of the underlying assets.
The assets continue generating yield while simultaneously serving as the backing for card transactions. With Ether.fi’s model, users aren’t liquidating positions every time they tap to pay. They’re borrowing against them or drawing from earned yield, keeping their core holdings intact.
What to watch from here
The trajectory from $200 million at the end of 2025 to $800 million by September 2026 is a fourfold increase in roughly nine months. The 26% revenue contribution in Q1 suggests this isn’t a loss-leader marketing exercise.
