Dev Tools Guild July update

TL;DR: Ethereum and Solidity turn ten. Ethereum Foundation, Octant and Optimism's Retro Funding support member projects. Gas limit to 45M. Partial history expiry. Fusaka upgrade: targeting Q4. Glamsterdam upgrade: feedback wanted on proposed headliners

Dev Tools Guild members

• Argot Collective (includes Solidity & Sourcify) secured three years of operational funding from the Ethereum Foundation.
• Golem Foundation's Octant Epoch 8 supported Solidity, Vyper, ethers.js and Scaffold-ETH (via BuidlGuidl).
• Optimism's Retro Funding: Dev Tooling continues to support Solidity, Vyper, alloy, ethers.js, Nethereum, viem, web3.py, Ape Framework, Foundry, Scaffold-ETH and Sourcify.

Smart Contract Languages

Solidity

• Celebrating 10 years of Solidity.
• Join the Language Design calls (Wednesdays 13:00 UTC) to learn about current priorities and upcoming changes.

Vyper

• Vyper EthCC workshop: basic - deploy a token with Snekmate or advanced - Venom IR optimization.

Client Libraries

alloy

• alloy v1.0.17 - v1.0.23.

viem

• viem 2.31.7 - 2.33.1: includes initial support for Flashblocks (up to 200ms transaction preconfirmations).

web3.py

• web3.py v7.12.1.

Web3j

• Two mentorships have started and are currently ongoing.

Frameworks and Dev Environments

Ape Framework

• Uniswap SDK v0.3.0: includes new solver implementation and uni CLI.

Foundry

• Foundry v1.3.0-rc1 - v1.3.0-rc4: includes forge lint support, time-based campaigns and coverage-guided fuzzing for invariant tests, table tests, fork test improvements for Reth clients and new EIP-712 features.

Scaffold-ETH

• create-eth v1 CLI launched. (currently v1.0.2): more flexible/customisable, allowing extension developers to build more powerful extensions on top of Scaffold-ETH.

Standardisation Tooling

Sourcify

• New Verification UI: uses Sourcify APIv2 for clear error messages, onchain vs recompiled diffs and one-click GitHub issue reporting for failures.
• Otterscan integrated Sourcify APIv2 to link revert traces to verified contract code.
• 8.5 million contracts verified, includes 1.2 million on mainnet.

Ethereum Layer 1

Ethereum turns ten. 🍰

Gas limit increase

• Gas limit on mainnet can safely be raised to 45M, ~48% of validators are signaling for 45M.

History expiry

• Partial history expiry: nodes can run without pre-Merge data, saving 300-500GB in disk space.

Fusaka upgrade (target Q4 2025)

• Ideally upgrade mainnet before Devconnect (17-22 November) but timeline is tight.
• Headliner is L2 scaling via EIP7594 PeerDAS and EIP7892 Blob parameter only upgrades.
• EIP7907 to increase the contract code size cap was unfortunately removed, due to unresolved complexity & timeline risks.
• Current devnet: Fusaka-devnet-3 (specs).

Glamsterdam upgrade (target 2026)

• Glamsterdam proposed headliners & client team perspectives:
  • Stakeholder feedback wanted on proposed headliners.
  • Execution layer client teams favor EIP-7928 block level access lists (BALs) + repricing.
  • Consensus layer headliner short list: EIP7732 ePBS, EIP7782 6-second slots and EIP7805 FOCIL.
• EIPs (non-headliners) can be proposed for inclusion via PRs to the upgrade meta EIP.
