Execution activity on public smart contract networks has substantially migrated to Layer-2 (L2) scaling solutions. Offloading transaction execution from the Ethereum mainnet has drastically altered on-chain fee dynamics and protocol revenues.
Data Availability Layer Integration
The implementation of specialized data availability layers has reduced L2 post-data fees by over 90%. This cost reduction enables micropayment applications and decentralized social protocols to operate with sub-cent user transaction costs.
Liquidity Fragmentation Challenges
While throughput has scaled significantly, capital across distinct L2 ecosystems remains fragmented. Interoperability protocols and cross-chain messaging bridges are becoming central infrastructure requirements for decentralized finance liquidity.
