Ether.fi's CASH card, a Visa-linked product that allows users to spend directly from their crypto vaults, has surpassed $800 million in cumulative spend as of early September 2026. Roughly $600 million of that total was generated this year alone. The milestone places CASH among the more heavily used crypto-linked spending products, at a time when stablecoin payments and tokenized deposits are drawing increased attention from both crypto firms and traditional payment networks.

The numbers behind the surge

Q1 2026 saw $170 million in spend volume, a 35% increase from the previous quarter. By late April, cumulative spending had already exceeded $400 million, with monthly volumes regularly topping $50 million even amid choppy market conditions.

By early September, the CASH product had processed nearly 10 million transactions. The average transaction size—below $100—is perhaps more telling than the raw volume. That pattern indicates users are not making a handful of large purchases to game cashback rewards; they are buying coffee, paying subscriptions, and covering everyday expenses. For context, that $100 average puts CASH transactions in the same range as typical everyday card purchases on conventional payment networks, suggesting the product is being used as a substitute for ordinary spending rather than as a niche crypto tool.

The platform currently supports approximately 70,000 active cards and around 300,000 accounts. These figures grew meaningfully after Ether.fi migrated the CASH product to Optimism's OP Mainnet in February 2026, a move consistent with the broader industry shift of consumer crypto applications onto layer-2 networks to reduce transaction costs and settlement times.

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 is derived from a mix of interchange fees, foreign exchange activity, and lending operations tied to the card's underlying mechanics. Diversifying revenue toward payments is notable for a protocol that built its base in liquid staking, where income is largely tied to staking yields and protocol fees rather than consumer spending.

Why this model is different

Crypto debit and credit cards are not new—Coinbase, Crypto.com, and others have offered them for years. What distinguishes Ether.fi's CASH product is its non-custodial structure. Users are not depositing funds with a centralized entity that issues a card; they are spending from self-custodied vaults, meaning the protocol never takes possession of the underlying assets. That distinction matters in a sector where several centralized card and lending programs have collapsed or frozen withdrawals, events that pushed parts of the industry toward self-custody designs.

The assets continue generating yield while simultaneously serving as the backing for card transactions. With Ether.fi's model, users are not liquidating positions each time they tap to pay. Instead, they borrow against their holdings or draw from earned yield, keeping core holdings intact.

What to watch from here

The trajectory from $200 million at the end of 2025 to $800 million by September 2026 represents a fourfold increase in roughly nine months. The 26% revenue contribution in Q1 indicates this is not a loss-leader marketing exercise. Going forward, the indicators that will shape the picture include whether the OP Mainnet migration sustains account growth, whether regulatory treatment of non-custodial card programs remains stable, and whether average transaction sizes and monthly volumes hold as the user base broadens beyond early adopters.
