Ethereum development activity accelerated through August as builders across the ecosystem shipped new upgrades, launched fresh protocols, and expanded institutional integrations. Layer-2 networks advanced their infrastructure, decentralized finance protocols recorded fresh deposit milestones, and privacy-focused applications gained new momentum. The developments touched governance, tokenization, wallet security, and onchain gaming across the wider Ethereum landscape.

Institutional and Layer-2 Expansion Gain Momentum

Ethereum's Layer-2 ecosystem saw structural changes this month. GnosisDAO approved a vote to move Gnosis Chain from an independent Layer-1 network to a ZK-proven Ethereum Layer-2 rollup. The shift introduces synchronous composability, allowing applications on Gnosis and Ethereum to interact within a single transaction. The move reflects a broader pattern in which standalone chains are aligning with Ethereum's rollup-centric roadmap, either by building on the OP Stack or adopting zero-knowledge proofs to inherit Ethereum's security model.

Institutional interest in Ethereum also expanded. BlackRock introduced its Select Treasury Based Liquidity Fund with a tokenized share class deployed on Ethereum mainnet. The asset manager additionally began tokenizing share classes tied to its $311 billion European money market fund series on the network. Ethereum mainnet has become a common settlement layer for tokenized real-world assets, and the addition of money market fund share classes extends a trend that has already brought tokenized Treasuries and funds from multiple major issuers onchain.

Ethereum is for shipping.

Arbitrum activated its ArbOS Elara upgrade, bringing more responsive transaction fees to Arbitrum One. The update also increased Stylus smart contract capacity fourfold and added new features for chains built on the Arbitrum stack. The Stylus expansion matters because it lets developers write contracts in mainstream programming languages such as Rust alongside Solidity, broadening the pool of builders who can deploy on the network.

Elsewhere, Whitechain, the network connected to the WhiteBit exchange ecosystem, announced plans to transition from an independent Layer-1 into an Ethereum Layer-2 built on the OP Stack, the open-source framework that underpins Coinbase's Base among other chains.

Ethereum client teams also introduced the Platåberget testnet to prepare implementations ahead of the Glamsterdam network upgrade, continuing the multi-client testing process used ahead of prior protocol upgrades to coordinate independent client implementations.

Privacy Tools and Wallet Infrastructure Advance

Privacy-focused development remained active across the Ethereum ecosystem in August. Aztec Network launched Alpha v5, a protocol upgrade that reduced private transaction proving times. The release also brought an initial group of privacy-preserving applications onto the network.

Privacy Boost introduced a new frontend application enabling users to send private transfers directly from connected wallets.

Separately, Privacy Pools launched onchain payroll support, letting employers issue recurring wage payments while keeping salary amounts and recipient addresses private.

Wallet security also advanced through new releases. MetaMask launched its Agent Wallet, an agentic tool built with spending limits, allowlists, and configurable risk profiles. The design addresses a growing need for guardrails as AI agents increasingly initiate onchain transactions on users' behalf.

Freedom Factory opened presales for PQ1, an air-gapped hardware wallet that signs transactions using post-quantum cryptography through an Ethereum smart account. Post-quantum approaches have gained industry-wide attention as standardization bodies and blockchain projects work to prepare for a future in which quantum computers could threaten current signature schemes.

Privacy-focused wallet Cloaked reported reaching $650,000 in deposits and $1 million in transaction volume during its first 90 days of operation.

Web3Privacy also released an updated Ethereum Privacy Ecosystem Mapping for 2026, documenting the network's growing privacy tooling landscape.

DeFi Growth and Ecosystem Programs Continue

Decentralized finance activity on Ethereum showed continued expansion during the month. Aave v4 surpassed $525 million in deposits on Ethereum mainnet.

Morpho reported crossing $880 million in total deposits on Robinhood Chain within less than two months of going live, while also reaching $5.75 billion in deposits on Base.

Uniswap processed more than $1 billion in stock token volume on Robinhood Chain, contributing to over $20 billion in total volume since the platform's July launch. The exchange also launched v4 Permissioned Pools, a hook standard enabling allowlisted swaps for regulated assets while keeping the base protocol permissionless. Tokenized equities have emerged as one of the fastest-growing onchain asset categories this year, with multiple trading venues and issuers now offering stock exposure through blockchain-based wrappers.

Coinbase launched tokenized stocks on Base for non-U.S. users, backed one-to-one by a regulated custodian and held in self-custody wallets. Base separately opened applications for its Base Batches 004 accelerator program, supporting ten early-stage teams building on the network.

Ether.fi expanded its crypto neobank offering with tokenized stocks and portfolio-backed loans facilitated through Aave.

The Ethereum Foundation also launched an autoresearch challenge focused on post-quantum security, built alongside zkSecurity and EigenLabs, placing a machine-verified security problem on a public leaderboard for open contribution.
