EtherFi is moving its DeFi-native credit card service, EtherFi Cash, to the Optimism mainnet, The Block reported on Feb. 18.

EtherFi said about 70,000 active cards, about 300,000 accounts and user deposits worth several million dollars will move to Optimism in the coming months.

EtherFi Cash is a non-custodial service that lets users spend stablecoin balances directly for payments or borrow against staking and restaking assets such as eETH (eETH) and use the funds.

Earnings also accrue, and the service offers cashback benefits like traditional cards. The EtherFi card, usable at any Visa merchant, accounts for nearly half of all crypto-native payment card transactions.

The EtherFi card currently operates on Scroll, a zero-knowledge proof-based Ethereum layer-2 blockchain. EtherFi's core restaking protocol has mostly operated on the Ethereum mainnet.

EtherFi explained that migrating to the Optimism mainnet will allow it to secure swap liquidity in a larger DeFi ecosystem, increase the assets available for deposits and withdrawals, and support gas-fee sponsorship. EtherFi said, "From the user's perspective, the transition will be seamless," and added, "Optimism has previously supported large-scale ecosystem migrations and has a safe process designed to minimize confusion."
