Ethereum’s Layer 2 landscape is increasingly a volume game, and OP Mainnet is playing it well. Monthly transactions on the network are now three times higher than levels recorded in early 2024, a climb that accelerated sharply through what the Optimism team internally tracks as “Year 4.”
That period alone saw monthly transaction counts surge more than 60%, driven by a combination of collapsing fees, high-profile project arrivals, and infrastructure changes that made the network meaningfully faster and cheaper to use.
What’s actually driving the numbers
The single clearest catalyst in recent months has been ether.fi’s migration of its non-custodial crypto card product onto OP Mainnet, completed between February and April 2026.
The move brought roughly $220 million in total value locked to the network, added 300,000 new accounts, resulted in 70,000 Visa debit cards being issued, and is generating around $2 million in daily payment volume.
On February 5, 2026, that load hit a single-day record: 3,823,880 transactions processed in 24 hours.
Fees are a significant part of the story too. By Q4 2024, average transaction costs on OP Mainnet had fallen to $0.03, a direct consequence of EIP-4844’s blob data availability upgrade that reduced the cost of posting transaction data to Ethereum’s base layer.
Infrastructure bets paying off
The network has also been making structural changes that go beyond raw throughput. Fault proofs, a mechanism that allows anyone to challenge potentially invalid state transitions without needing to trust a central operator, have been implemented. This matters because it moves OP Mainnet closer to the “Stage 1” decentralization benchmark that researchers like L2Beat use to evaluate rollup maturity.
Starting May 26, 2026, Optimism also kicked off a four-week experiment with stake-based transaction ordering. Under this model, holders of the OP token who stake their tokens gain priority in how their transactions get sequenced.
What this means for the OP Stack ecosystem
OP Mainnet does not exist in isolation. It anchors the OP Stack, a shared codebase that powers a growing number of chains including Base, which Coinbase launched in 2023. The relationship is collaborative rather than competitive: chains built on the OP Stack route a percentage of sequencer revenue back to the Optimism Collective, creating a flywheel where more chains mean more funding for Optimism’s development.
The ether.fi migration is a particularly useful data point because it represents a product with genuine consumer adoption, not just protocol-to-protocol liquidity flows. Seventy thousand issued Visa cards generating $2 million in daily payment volume is the kind of traction that turns skeptics into infrastructure customers.
