Ether.fi is preparing to migrate its Cash product to OP Mainnet, moving 70,000 active cards and about 300,000 digital cash accounts from Scroll. The transition will occur over the coming months under a long-term partnership with OP Enterprise. The shift moves millions in user assets to Optimism as the network seeks to strengthen its payments ecosystem.

Ether.fi Cash offers users a way to convert fiat to crypto, earn yield through DeFi strategies, and make global payments using a Visa-accepted card. The product also allows users to manage assets through a non-custodial wallet. According to the company, the system processes about 2,000 internal swaps and 28,000 daily spend transactions.

A Dune Analytics dashboard shows Ether.fi accounts for more than one quarter of spending volume across major crypto card providers. That share, combined with rapid user growth, has made the product one of the most active payment tools in the crypto sector.

Optimism Positions OP Mainnet as a Payments Hub

An Optimism spokesperson said the migration brings one of the fastest-growing crypto payment apps to OP Mainnet. The spokesperson said the product processes about $2 million in daily real-world volume while removing DeFi complexity for everyday users. Optimism said this shows the value of the OP Stack for payment-focused firms.

Optimism reported that the OP Stack processed 3.6 billion transactions during the second half of 2025. The network accounted for about 13 percent of total crypto activity during that period. The company said this scale provides the depth needed to support large-volume consumer applications.

The organization also said it has experience managing migrations for major ecosystems such as Celo, Lisk, and Ronin. Because of this, the team expects a smooth transition for Ether.fi customers. As part of the OP Enterprise model, Ether.fi will gain access to shared liquidity, enterprise-grade tools, and future upgrades within the Superchain.

Industry Shifts as Base Plans to Exit OP Stack

The Ether.fi news comes during a moment of change for layer-2 networks. Coinbase announced that its Base network will shift away from the OP Stack to a self-managed codebase. The move affects Optimism because Base has generated most of the Superchain’s revenue. OP tokens fell after the announcement.

Still, Ether.fi’s migration gives Optimism a new source of activity. The Cash product’s strong transaction volume may help offset some concerns about future revenue. The move also supports Optimism’s plan to establish OP Mainnet as a center for payments and consumer crypto activity.

Robinhood’s testnet also recorded four million transactions in its first week, showing wider growth across layer-2 infrastructure. Networks remain focused on real-world payments, tokenized assets, and accessible financial tools as competition increases.

A Growing Role for Consumer DeFi Applications

Ether.fi’s broader protocol secures about $5.7 billion in total value locked, according to DefiLlama. The Cash migration signals a deeper focus on consumer DeFi use cases. Optimism said OP Mainnet will serve as a settlement and liquidity hub within the Superchain.

The transition marks a new stage for Ether.fi as it works to expand its user base. It also shows how payment products are reshaping the layer-2 landscape during a period of market uncertainty.
