ether.fi has officially migrated to OP Mainnet. This move marks an important stepping stone in ether.fi's journey to become the best solution for anyone to move their financial life on chain.


A New Chapter

Today, we’re excited to announce our migration to OP Mainnet is complete. 70,000+ active cards, 300,000+ accounts, and $200M+ in TVL now live on OP Mainnet, bringing one of the largest DeFi protocols to Optimism’s product ecosystem.

As the largest non-custodial crypto card by spend volume, ether.fi is committed to providing the best possible service to our users. OP Mainnet gives us the infrastructure to deliver on that commitment: $0.00001 median transaction fees, sub-250ms finality via Flashblocks, and 99.99% uptime year to date. Migrating to OP Mainnet is a significant step in becoming a mass market fintech product that allows you to move your financial life onchain.
