Ether.fi, a decentralized staking protocol, is set to migrate its DeFi-native crypto card, ether.fi Cash, from the Scroll network to the OP Mainnet (Optimism Mainnet). The transition, expected to take several months, will involve around 70,000 active cards, 300,000 accounts, and millions in user locked assets. The ether.fi Cash card allows users to spend stablecoins or borrow against staked assets while earning rewards and cashback, and is accepted at Visa-supporting merchants. Ether.fi cards currently represent nearly half of all crypto-native payment card transactions. The OP Stack, which processed 3.6 billion transactions in the latter half of 2025, will support this migration with its high-throughput infrastructure.
