Ethereum Layer-2 Fees Slashed 90% After Dencun Upgrade Drives Adoption While Keeping Mainnet Stable

• Dencun upgrade has cut gas fees on Ethereum layer-2 networks by over 90%, with median fees falling to $0.01 or less

• Cheaper fees enabled by new proto-danksharding and blobs for temporary layer-2 data storage

• Lowest gas fees seen on Arbitrum, Starknet, Optimism, Base, and Zora networks post-upgrade

• Polygon not fully integrated yet, but expects full integration within 1-2 months

• Network usage has doubled or tripled on several layer-2s post-upgrade, but Ethereum mainnet activity remains steady
