In a major strategic move within decentralized finance, the non-custodial liquid staking protocol Ether.fi has announced the migration of its crypto-native credit card product, Ether.fi Cash, from the Scroll Layer 2 network to the Optimism mainnet. The decision, confirmed for March 2025, represents one of the largest user-base transfers between competing Ethereum scaling solutions.
The migration will directly impact approximately 70,000 active cards and a total of 300,000 user accounts over the coming months, alongside millions of dollars in total value locked (TVL). According to the protocol's team, the move is designed to leverage Optimism's more robust liquidity ecosystem and established infrastructure, aiming to provide users with a smoother experience for spending stablecoins or using restaked eETH as collateral.
The Ether.fi Cash product accounts for nearly half of all crypto-native card transactions in the market, making its integration into the Optimism Superchain a significant event. The transition is expected to facilitate higher-liquidity swaps and more efficient gas management for users. The migration process will be phased to ensure security and a seamless user experience, with the team emphasizing that all user funds and card functionalities will remain secure and operational throughout, consistent with its non-custodial philosophy.
Analysts view the shift as a signal of the evolving hierarchy among Layer 2 networks, where ecosystem strength, interoperability, and developer activity are becoming critical differentiators. The move from Scroll, a zkEVM rollup, to Optimism, an optimistic rollup part of the OP Stack, suggests Ether.fi prioritizes broad ecosystem integration and long-term network stability for its high-transaction-volume financial product.
