Decentralized staking protocol Ether.fi announced that its DeFi-native crypto card product, ether.fi Cash, will be migrated from the Scroll Network to the OP Mainnet (Optimism mainnet). The migration will be completed over the next few months and is expected to involve approximately 70,000 active cards, 300,000 accounts, and millions of dollars in user-locked assets (TVL). ether.fi Cash provides a non-custodial crypto payment experience, allowing users to spend directly with stablecoins or borrow and spend using staked and re-staking assets (such as eETH) as collateral, while continuing to earn yields and enjoy cashback rewards similar to traditional bank cards. The card can be used at all merchants that support Visa. Data shows that Ether.fi cards currently account for nearly half of crypto-native payment card transaction volume, making them one of the leading products in the field. Meanwhile, the OP Stack processed approximately 3.6 billion transactions in the second half of 2025, accounting for 13% of the total crypto transaction volume during the same period, providing high-throughput infrastructure support for this migration.
