The Ethereum market, buoyed by L2 adoptions, experiences notable changes. User and developer adoption surged, securing over $42 billion on chains like Arbitrum and Optimism.
Fees and transaction times decrease, positively impacting users.
“The path that we are taking to scale Ethereum is layer 2 protocols (L2s). The L2s of 2025 are a far cry from the early experiments they were in 2019: they have reached key decentralization milestones, they are securing billions of dollars of value, and they are currently scaling Ethereum’s transaction capacity by a factor of 17x, dropping fees by a similar amount.” – Vitalik Buterin, Co-founder, Ethereum Foundation
These advancements have economic implications, notably lowering costs. Transactions process at a rapid pace, with fees reduced significantly. This scenario enhances Ethereum’s competitiveness against other blockchains and decongests the Ethereum Layer 1 chain.
