ether.fi Cash to Migrate Accounts and Cards to OP Mainnet

• ether.fi moves Cash to OP Mainnet under an OP Enterprise partnership.
• Migration covers cards, accounts, and balances without disruption; gas fees stay covered.
• Cash has processed $265M spend since 2024, with usage doubling about every two months.

ether.fi announced plans to migrate its Cash accounts and card product to OP Mainnet, according to ether.fi. The move covers roughly 70,000 active cards, 300,000 accounts, and significant user TVL. The transition will occur over coming months through a long-term OP Enterprise partnership with Optimism.

Migration Scope and Partnership Structure

The migration places ether.fi Cash on OP Mainnet within the Superchain. According to ether.fi, the process will move accounts, cards, and balances without disrupting current usage. Notably, ether.fi will operate as an OP Enterprise customer, which includes enterprise support and shared tooling.

Through the partnership, ether.fi gains access to liquidity already active on OP Mainnet. However, the company also retains a single codebase across OP Stack chains. In addition, Optimism provides a dedicated account manager and priority access to upgrades.

The companies said the arrangement aligns around scaling global payments on public blockchain infrastructure. For Optimism, the deployment adds a high-activity payments product to OP Mainnet. The chain already serves as a hub for DeFi and enterprise applications.

ether.fi Cash Product and Usage Metrics

ether.fi Cash combines a non-custodial wallet, savings account, and credit card using DeFi infrastructure. Users can move between fiat and crypto, earn yield, and spend globally. The product also supports cashback and asset management within one application.

Since launching Cash in September 2024, ether.fi reports $265 million in total spend volume. Each day, the app processes about 2,000 internal swaps and 28,000 spending transactions. Notably, average daily spend reaches roughly $2 million.

These usage figures have doubled approximately every two months since launch. As a result, ether.fi said it required infrastructure aligned with Ethereum and global payment demands.

User Impact and Network Context

During the migration, ether.fi said accounts remain safe and usable. The company plans to coordinate closely with Optimism to ensure a secure transition. Until completion, users can continue using ether.fi products without changes.

Once integrated, ether.fi users will access OP token rewards through existing programs. These include cashback, in-app campaigns, and membership benefits. Gas fees for card transactions will remain covered by ether.fi.

In the second half of 2025, the OP Stack processed 3.6 billion transactions, representing 13% of all crypto transactions. OP Mainnet functions as a shared execution layer across the Superchain ecosystem.
