One of the world’s top crypto payment card companies, Etherfi, has announced the migration of approximately 70,000 active cards, 300,000 user accounts, and $200 million in assets to the OP Mainnet network. Company representatives said this move marked the single largest increase in total value locked (TVL) in OP Mainnet’s history. With this substantial transfer, Etherfi expects a significant rise in overall transaction volume on the OP Mainnet network.
Migration process and technical support
Etherfi reported that the entire transition was completed in just three days, with no interruptions or disruptions. The Optimism Foundation provided technical support throughout, lending expertise in bridge engineering, oracle services, and asset data integration. Etherfi’s platform had previously launched on the Scroll network, where it also accounted for a substantial share of TVL and transaction volumes. The company began signaling its plans to migrate to OP Mainnet back in February.
Currently, daily crypto card transaction volumes on OP Mainnet have jumped from 60,000 to 100,000 since the start of the year. According to data from The Block Research, Etherfi now handles about a third of all transactions by count in the sector and holds around 10% market share by transaction volume. Competing platforms such as Gnosis, Metamask, and Solayer also remain significant players in the market. At the beginning of the year, Etherfi’s share of transaction volume stood at close to 50%.
Why Etherfi chose OP Mainnet
Etherfi highlighted the low transaction fees and speed advantages that OP Mainnet offers when explaining its decision to migrate. Company officials noted that the average transaction fee stands at just $0.00001, while final confirmations are delivered in under 250 milliseconds.
“OP is raising its gas capacity per second from 20 million to 100 million. In the second half of 2025, OP Stack achieved 3.6 billion transactions, making up 13% of all crypto transactions,” Etherfi representatives emphasized, pointing to increased scalability.
The company stated that the OP Mainnet migration enables users to enjoy cheaper transactions and faster integration. In addition, the Etherfi team announced they are developing a euro-based card and a new product called Gold Vault.
Liquidity integration and ecosystem impact
The “Superchain” approach underlying OP Mainnet is designed to facilitate interoperability and liquidity sharing across diverse networks. Etherfi explained this model makes it easier to integrate with DeFi applications, build efficiency-driven strategies, and provide more competitive cashback options for cardholders.
The company stated,
“Every dollar brought to OP Mainnet makes the next dollar even faster and cheaper to transfer; Etherfi’s $200 million deepens liquidity pools and sets an example for other like-minded protocols.”
So far, Coinbase’s Base network has accounted for much of the transaction volume and activity within the OP Mainnet ecosystem. However, as Base shifts toward its own solution, OP Mainnet appears poised to diversify and attract a wider array of users.
