Ether.fi is Live on OP Mainnet
TL;DR: Ether.fi, the largest non-custodial crypto card by spend volume, is now live on OP Mainnet with $220M in TVL, 70,000 active cards, and 300,000 accounts. OP Mainnet is the home for one of crypto's biggest consumer fintech products, and the product roadmap that comes next starts here.
$220M in TVL. 300,000 accounts. One of crypto's biggest consumer products just chose its long-term home.
Ether.fi is on OP Mainnet
Ether.fi runs the largest non-custodial crypto card in the market. 70,000 active cards. 300,000 accounts. Millions of dollars in real-world payments every day. All of it is now on OP Mainnet, along with $220M in TVL. The largest single TVL event in OP Mainnet history.
The full migration took three days. Cards kept working the entire time. No downtime, no user complaints. The Optimism Foundation ran the move alongside the Ether.fi team, covering bridge engineering, oracle support, asset metadata, and the operational work behind a live consumer product. A migration this size, for a product this active, completed in days.
Why the product matters
The infrastructure move is the headline. The product is the reason it matters. EtherFi Cash is a best-in-class card experience — tap-to-pay anywhere Visa runs, instant settlement, global reach, the same speed and ease people already expect from their best traditional card. And every dollar sitting on it earns yield onchain. That is the combination no traditional credit card can match. Points and interest charges on one side, real onchain economics on the other.
That is the hook for every enterprise watching where consumer finance is going next. A best-in-class card experience plus yield built into the money itself. It is what a card becomes when the rails are onchain, and it is the reason a $5.8B protocol is putting its consumer product on OP Mainnet.
Why OP Mainnet
The decision came down to what the product actually needs. EtherFi Cash settles real payments every day, and at that volume, latency is money, fees are churn, and uptime is the product. The team evaluated the options and OP Mainnet was the only chain whose performance profile matched what consumer-scale cards require.
The numbers:
Median fees: $0.00001
Finality: sub-250ms via Flashblocks
Throughput: 20Mgas/sec, scaling toward 100Mgas/sec
Uptime: 99.99%
Data feeds: powered by Pyth Network
For a payment product that settles real money every day, those are the conditions the product needs to grow. Optimism is committed to scaling OP Mainnet cheaply as the protocols on it get bigger. The infrastructure gets better as Ether.fi's product gets bigger.
New asset support also opens the product roadmap Ether.fi has been building toward. A Gold Vaults and a Euro card are next. Native minting, deeper DeFi integrations, broader yield strategies, and richer cashback economics all get easier from here. The product work is what this was for. OP Mainnet is the platform that makes it possible.
"EtherFi Cash is the largest non-custodial crypto card in the market, and the roadmap we've been building is why. To ship what comes next, we needed infrastructure that could handle real-time payments at consumer volume. OP Mainnet delivered on every dimension. Three days to migrate $220M with no downtime answered the question. Now we get to build."
Mike Silagadze, CEO, Ether.fi
What $220M changes
Every dollar that arrives on OP Mainnet makes the next dollar cheaper to move, easier to pair, and faster to put to work. That is the flywheel. Ether.fi's $220M deepens every liquidity pool already here, and it changes the calculation for the next protocol weighing the same decision.
If you're building a consumer product that needs real throughput, finality, and asset support to scale, OP Mainnet is ready for it. The migration path is proven, it runs in days, and the liquidity is already here. Ether.fi picked OP Mainnet for the infrastructure and stayed for the partnership. That combination is what's on the table for every team evaluating the same move.
"This is what OP Mainnet is for. A live consumer product at this scale picks the infrastructure it needs for the next chapter, and we're building with Ether.fi for what comes next. Every dollar that lands deepens the liquidity for everyone already here."
