Ether.fi, a decentralized staking protocol, announced the migration of its DeFi-native crypto card ether.fi Cash from the Scroll network to the OP mainnet on Optimism. The transition is expected to be completed in the coming months and could involve roughly 70,000 active cards, 300,000 accounts, and millions of dollars in user deposits (TVL).
The ether.fi Cash card provides a non-custodial payments experience, allowing users to pay with stablecoins directly or to borrow using staked and restaked assets (such as eETH) as collateral while continuing to earn yields and receiving cashback similar to traditional bank cards. The card will be usable at all merchants that accept Visa.
Data show that Ether.fi currently accounts for nearly half of native crypto card transaction volume, making it one of the leading products in the space. The OP Stack processed about 36 billion transactions in the second half of 2025, accounting for roughly 13% of total crypto trading volume during that period, and it provided high-throughput infrastructure to support the migration.
