Ethereum Q1 activity spike

Ethereum just posted one of the strangest quarters in its history. In the first three months of 2026, the network processed about 200.4 million mainnet transactions, up 43% from the prior quarter. Active addresses reportedly exploded by roughly 1,704% to 12.6 million. That is not a small rebound. It is a step change in how busy Ethereum looked on chain. (finbold.com) The obvious question is why a chain built around pushing activity off the base layer is suddenly printing record base-layer numbers. The answer starts with Ethereum’s own design choices. Since the Dencun upgrade in March 2024, Ethereum has explicitly leaned into a rollup-centric model. Dencun activated EIP-4844, which added cheap “blob” storage for layer-2 rollups, cutting the cost of posting compressed transaction data back to Ethereum and making it easier for those networks to scale. (ethereum.org) That sounds like a story about activity leaving mainnet. In practice, it also creates more reasons to touch mainnet. Rollups execute transactions away from Ethereum’s base layer, but they still anchor themselves to Ethereum for data availability, settlement, and proofs. When more users pile into networks like Arbitrum and Base, some of that growth shows up on Ethereum itself as bridging, settlement, and other support traffic. The system is fragmented, but it is still one machine. (ethereum.org) That helps explain why the quarter’s headline is not just higher throughput, but a surge in addresses. One report tied the jump directly to layer-2 growth and pointed to Ethereum’s stablecoin base as another source of demand. Another snapshot of the quarter showed daily activity peaking at about 2.897 million transactions on February 7 before easing back above 2.3 million by early April. Even after that cooldown, Etherscan still showed roughly 2.36 million transactions in 24 hours and an average transaction fee near 16 cents. This was not a one-day spike. It lasted. (bingx.com) But the surge comes with a catch that says a lot about Ethereum in 2026. More usage no longer means more fee capture on the base chain. Dencun made rollups cheaper by design. That is good for users. It is less good for the old Ethereum story in which congestion on mainnet translated into rich fees and a simple measure of demand. By March, market reports were already describing a disconnect between record network activity and weak fee generation at the base layer. (ethereum.org) So the quarter’s record is real, but it does not mean Ethereum has returned to its old form. It means Ethereum is turning into infrastructure that other execution layers lean on. The center of gravity is shifting from “how expensive is mainnet” to “how much economic activity still settles back to Ethereum.” That is a subtler metric, and a harder one to celebrate in a single chart. Still, the concrete number is hard to ignore: on April 6, Etherscan showed 3.368 billion lifetime Ethereum transactions, after a quarter in which 200.4 million of them arrived in just 90 days.
