Recently, ether.fi has announced plans to migrate its fast-growing ether.fi Cash product to OP Mainnet, marking a long-term partnership aimed at expanding global onchain payments.
The transition will shift more than 70,000 active cards and over 300,000 user accounts onto the network in the coming months. More than $160 million in total value locked will also move as part of the integration.
The move indicates that the network is working towards developing infrastructure that will be capable of processing more payment transactions. ether.fi Cash, which was launched last year, integrates digital banking services with decentralized finance services.
The platform allows users to convert fiat to crypto, earn interest, spend money anywhere in the world, and track assets using a non-custodial wallet. The service integrates savings accounts, credit cards, cashback, and rewards into one service.
Usage is increasing rapidly. The network’s app processes approximately 2,000 internal swaps per day and 28,000 spend transactions. Average daily spend is approximately $2 million.
The company claims that these figures have doubled approximately every two months since launch, placing ether.fi Cash ahead of several established rivals in the crypto payments space.

Aligning ether.fi with Ethereum’s Scalable Infrastructure
By participating as an OP Enterprise customer, ether.fi immediately gains access to existing liquidity and users. The collaboration allows for enterprise-level support on a public blockchain, a technical account manager, and common tools for all OP Stack chains. ether.fi will also have priority access to upgrades and new features.
For Optimism, the integration improves the position of OP Mainnet as one of the leading networks for payment transactions. In the latter half of 2025, the OP Stack processed 3.6 billion transactions, which accounted for 13% of the total cryptocurrency transactions at that time.
OP Mainnet is now a hub for decentralized finance and a launchpad for consumer and business applications in the Superchain ecosystem.
The migration aligns the network with the Ethereum ecosystem. The network began developing ether.fi Cash in 2024 and was searching for an infrastructure partner that could process many transactions globally. Optimism is now the infrastructure partner.
What Users Can Expect After the Migration
The transition to OP Mainnet will be seamless for users. Major migrations within the ecosystem in the past have been smooth, and this one will not be an exception. Users will enjoy higher liquidity for swaps, more assets, and faster transactions.
Gas fees and network charges for card transactions will be covered by Ether.fi. Cashback rewards are expected to increase, with rewards such as 3% or higher cashback, travel benefits, membership levels, lounge access, and free metal cards.
