According to the source, Ethereum is reportedly handling 1.6M+ daily transactions while average fees hover near ~$0.01, a claim traders should validate against Etherscan for L1 activity and L2Beat for rollup fees to distinguish Layer 1 from Layer 2 costs, source: the source; Etherscan; L2Beat. Post-Dencun (EIP-4844) introduced blob space that cut L2 data availability costs and enabled cent-level fees on major rollups, as documented by the Ethereum Foundation, source: Ethereum Foundation. OP Labs and the Arbitrum team publicly reported significant fee reductions on OP Mainnet and Arbitrum following EIP-4844 implementation, supporting lower L2 transaction costs, source: OP Labs; Arbitrum Foundation. For ETH valuation mechanics, higher L1 utilization increases base fees and EIP-1559 burn, impacting net issuance that can be tracked on Ultrasound Money, source: Ethereum.org (EIP-1559); Ultrasound Money. Trading checklist: confirm L1 daily transactions and gas via Etherscan, check L2 fee and throughput trends via L2Beat, and compare DEX volumes on L2s via Dune Analytics to assess whether low-fee activity is sustainable, source: Etherscan; L2Beat; Dune Analytics.

According to the source, an Ethereum upgrade dubbed Fusaka is claimed for December 3 to make layer-2 transactions cheaper, but this timing and upgrade name are not confirmed on the Ethereum Foundation blog or AllCoreDevs repositories; traders should treat it as unverified and wait for official client release notes, source: Ethereum Foundation; Ethereum AllCoreDevs GitHub. For context, prior L1 scaling work such as EIP-4844 in the Dencun upgrade reduced L2 data availability costs and lowered typical user fees across major rollups, which historically supported higher activity and throughput, source: Ethereum.org EIP-4844; L2Beat analytics. If official confirmation arrives, trading checklist: watch ETH funding and options implied volatility into and after the fork, track L2 fee prints and blob gas prices to gauge cost reduction magnitude, and map beta on OP, ARB, and MATIC versus fee changes using on-chain dashboards before taking positions, source: Deribit metrics; L2Beat fee tracker; Ethereum client release notes; ultrasound.money blob fee charts.

According to @EmberCN, Offchain Labs chose Succinct Labs in August to help Arbitrum transition to zero knowledge verification, and the teams have now reached a milestone as Succinct’s SP1 has successfully verified Arbitrum blocks while remaining compatible with the existing Ethereum stack, source: @EmberCN; Succinct Labs on X post 1980664325489730014. @EmberCN states this meets the expected verification goal and marks staged progress toward applying ZK verification on Arbitrum and moving toward large scale ZK validation on Ethereum, source: @EmberCN. For traders, the confirmed technical progress offers a concrete upgrade marker to track for ARB and ETH market reactions alongside any subsequent rollout communications from Offchain Labs and Succinct Labs, source: @EmberCN; Succinct Labs on X post 1980664325489730014.
