Ethereum Energy Use Report

The Cambridge Centre for Alternative Finance published an updated assessment of Ethereum's environmental footprint years after the Merge. The report conducted a bottom-up audit of 8,522 physical nodes, measuring actual hardware configurations and the carbon intensity of the grids powering them. The report found that Ethereum now consumes approximately 7.87 GWh of electricity annually, less than half the British Museum's annual energy use, running at a continuous draw of roughly 0.90 MW. The reduction is more than 99.9% below its pre-Merge baseline of around 2.4 GW, which once rivaled the electricity demand of a small country.

ArbitrumDAO OAT Committee Elections

The ArbitrumDAO is holding an election for its Oversight and Transparency Committee (OAT), the five-member body that oversees OpCo, Arbitrum's centralized operational execution layer. The current committee published its July 2026 update reporting progress on hiring a Head of OpCo, operationalizing the structure, and coordinating cross-AAE initiatives. Arbitrum Autonomous Entities (AAEs) are independent organizations and service providers that operate within the Arbitrum ecosystem and funded by the ArbitrumDAO. Delegates and stakeholders were invited to engage directly on the forum

Robinhood Agentic Accounts

Robinhood launched agentic trading accounts for crypto, allowing eligible US customers to connect third-party AI models including Claude and ChatGPT to isolated Robinhood accounts for autonomous crypto trades. Users can set natural-language instructions, trade limits, and safety guardrails, with the AI agent continuously scanning market data and executing strategies autonomously within those parameters. Robinhood warns of risks including volatile markets and misread prompts.

Aave Introduces Stable Vaults

Aave Labs introduced Stable Vaults, fixed-rate stablecoin yield vaults built for easy integration into consumer applications. The product converts variable onchain lending rates into a fixed rate that applications commit to their users. Aave's infrastructure handles the rebalancing, cross-chain operations, and rate management as an all-in-one solution. It's designed for any business that wants to embed fixed-rate stablecoin yield into its product. Aave Labs uses Stable Vaults to power yield in the Aave mobile app. Operators choose which stablecoins to accept and which yield strategies to plug in, including Aave markets, Savings GHO, Veda vaults, or any ERC-4626 vault.

Devcon 8 Opens Speaker Applications

The EF Devcon Team opened speaker applications for Devcon 8, set to take place in Mumbai, India, from November 3–6, 2026. Applications are open to anyone building, researching, or teaching in the Ethereum ecosystem. Speakers can apply across four formats, including Lightning Talk, Talk, Mixed Format, or Workshop, and choose from nine tracks spanning Core Protocol, Privacy & Consent, Security, Applied Cryptography, and Permissionless Networks. Devcon expects the event to engage more than 10,000 attendees, though this year's program will accept fewer talks than Devcon 7,. Speaker applications close on August 6, 2026 at 23:59 UTC.

Disappearing Token Honeypot

Relay Protocol, a cross-chain liquidity provider, confirmed reports of scam tokens vanishing from wallets after purchase on Robinhood Chain, describing a wave of tokens deliberately designed to remove themselves post-purchase. The mechanism is a type of honeypot scam, where the token's smart contract contains hidden logic that silently burns the buyer's balance to zero, or reroutes it to the deployer, once triggered by a subsequent block or a set transaction count since launch, so the balance appears briefly before disappearing entirely. Relay said funds spent on these tokens are not recoverable, but stressed the exploit is isolated to the scam token purchase itself, with private keys and other wallet balances unaffected.

Privacy Pools V2 Ceremony

Privacy Pools launched the trusted setup ceremony for its V2 protocol, inviting contributors to add randomness to proving keys ahead of a mainnet deployment. To contribute, users can sign in via GitHub, generate entropy through mouse movement or clicks in a browser tab. The ceremony exists to prevent any single party from retaining the secret randomness used to build the proving keys, a scenario that would let a malicious holder forge withdrawal proofs and drain deposited funds. The full run across all circuits takes 15 minutes to an hour depending on hardware used,.

Arbitrum Supports For x402 and MPP

Arbitrum now supports Coinbase's hosted x402 facilitator, letting developers build x402-powered services without running their own settlement infrastructure. x402 embeds payment into the standard HTTP request-response code. It allows an agent requesting a paid API or data product can receive a payment requirement and respond programmatically as part of the same interaction. Separately, Offchain has published arbitrum-mpp, an open-source TypeScript SDK implementing the Machine Payment Protocol on Arbitrum.

Aave stkGHO to sGHO Migration Tool

Aave released a one-click migration tool for converting Staked GHO into Savings GHO, the protocol's new yield vehicle for GHO. Legacy stkGHO holders must migrate manually, since rewards on the old staking contract will taper over a seven-week transition schedule. Aave is urging stkGHO holders to move as soon as possible. Underlying GHO stays accessible even for holders who miss the migration window, but they stop earning yield once legacy rewards end.

Zapper Winds Down

DeFi portfolio aggregator Zapper is winding down, founder Seb Audet announced, closing a nearly seven-year run that began as a personal portfolio tracker built during the November 2019 Kyber DeFi Hackathon under the name DeFiZap. The project later merged with DeFiSnap in May 2020 to form Zapper, eventually scaling to more than 2 million monthly active users and processing more than $13 billion in transaction volume at its peak. Zapper's website, mobile apps, and API services will shut down completely on August 3, 2026.

The trusted setup design requires only one honest participant among all contributors to guarantee security. Each contribution is verified and a public Ethereum beacon will be applied at the end of the process, with the full transcript and resulting keys published for independent verification against standard tooling. The full run across all circuits takes 15 minutes to an hour depending on hardware used, and the ceremony is open now for contributions ahead of V2's deployment.

Separately, Offchain has published arbitrum-mpp, an open-source TypeScript SDK implementing the Machine Payment Protocol on Arbitrum. The package ships both client and server logic: the client produces a signed payment authorization in response to a server challenge, the server validates it, submits the transaction, and confirms settlement. Payments settle in USDC via signed transfer authorization, with no requirement for the payer to hold the gas token. Any token compatible with Uniswap's Permit2 is also supported.

Audet said the team weighed several alternatives before concluding an orderly wind-down was the best path forward. Zapper's website, mobile apps, and API services will shut down completely on August 3, with existing API users to receive migration guidance by email. The Zapper team is now available for hire, offering onchain engineering and operations experience at scale.

Lodestar Fast Confirmations

Lodestar, an Ethereum consensus layer client, supports the Fast Confirm Rule, allowing Ethereum node operators to confirm transactions in a single slot (~13 seconds) by using validator attestations. Fast Confirmation provides a middle ground, between the chain head and finalized status, for transaction confirmations. Rather than waiting ~12.8 minutes required for full transaction finality, providers can reasonably operate on 13-second confirmations under normal network conditions. The feature helps exchanges, bridges, and L2s speed up deposit and withdrawal processing times, resulting in a better experience for end users. The feature is still experimental and disabled by default.

Ondo Perps Goes Live

Ondo launched Ondo Perps, offering up to 20x leverage on perpetual futures for equities, commodities, and indices, with support for tokenized stocks as collateral on Ethereum. All markets trade 24/7 with no expiry dates. The launch brings capital efficiency, where a tokenized stock serves as both the hedge and the collateral simultaneously, roughly halving the capital required for the same quoting exposure. The platform is accessible globally outside the US with available markets spanning oil, gold, silver, Apple, Nvidia, Tesla, Microsoft, and Amazon. Ondo is also offering $150,000 in USDC rewards based on trading activity.

ZeroDev Launches Embedded Wallet

ZeroDev launched ZeroDev Wallet, an embedded wallet solution that completes its account infrastructure platform. ZeroDev Wallet unifies smart accounts, paymasters, bundlers, session keys, and policy infrastructure into a single stack. The wallet supports email, OAuth, and passkey sign-in, and integrates with wagmi and EIP-1193 transaction flows.. ZeroDev Wallet starts from with smart accounts, meaning permissions, automation, gas abstraction, and session key infrastructure are available from day one rather than bolted on later.

L2BEAT Lists Robinhood Chain

L2BEAT listed Robinhood Chain, a L2 built on Arbitrum's Orbit stack, now securing over $250 million in value. The chain uses ETH as its gas token and posts data to Ethereum using blob transactions. The chain is focused on tokenized real-world assets and onchain financial services including 24/7 trading, lending, and borrowing of Token Stocks. Of the total value secured, about 91% is in stablecoins, with USDG alone accounting for $220 million. Tokenized stocks and ETFs make up around 4% at the time of writing. L2BEAT classifies the chain under "Others" rather than as a full L2. Uniswap recently shared $250 million in trading volume on the chain.

The feature helps exchanges, bridges, and L2s speed up deposit and withdrawal processing times, resulting in a better experience for end users. The Fast Confirm Rule runs at the start of each slot, checks whether the current confirmed root still has sufficient attestation support under a configurable adversarial threshold (default: 25%), and either advances, stalls, or falls back toward finalized if assumptions no longer hold. The feature is experimental and disabled by default.

Of the total value secured, about 91% is in stablecoins, with USDG alone accounting for $220 million. Tokenized stocks and ETFs make up around 4% at the time of writing. Since launch, the chain has processed over 4.5 million user operations, with ~600k in the past day alone, per L2BEAT.

L2BEAT classifies the chain under "Others" rather than as a full L2 for two reasons. Fraud proofs using Arbitrum's BoLD system are deployed, but only two whitelisted validators can submit challenges, falling short of the decentralization threshold. The chain includes an authorized filterer that can register a transaction hash in an L2 precompile, causing the state transition function to forcibly fail that transaction even if it was force-included via L1.

This breaks censorship resistance guarantees that a forced-inclusion mechanism is meant to provide. Uniswap recently shared $250 million in trading volume on Robinhood Chain within its first week, though filtered analytics from DeFiLlama put actual volume closer to $50 million.

Vitalik Outlines Technical Strawmap Updates

Ethereum researchers and client teams updated the Ethereum technical roadmap known as the Strawmap. The revised framework charts a multi-year transition toward Lean Ethereum, which Vitalik Buterin characterized as the third major iteration of the protocol. The technical trajectory aims to systematically replace core components of the network over the next three to four years while preserving backward compatibility for existing apps.

The updated Strawmap focuses on enshrining recursive STARKs directly into the core protocol layer rather than continuing to rely on direct transaction re-execution. The EF Protocol Team has significantly elevated the priority of quantum-safe cryptographic designs, accelerating urgent research into finalizing quantum-resistant blob specifications. On the consensus layer, researchers seek to decouple the available chain from the finality engine, working toward a streamlined one or two-round finality mechanism to deliver simpler, optimal security properties. The roadmap also introduces multi-dimensional gas modeling alongside extensive client architecture simplifications.

Wahrstätter Proposes Native Ethereum UTXOs

Published by Ethereum Foundation researcher Toni Wahrstätter, a research proposal outlines a method to introduce native, optional UTXOs to Ethereum. The design addresses Ethereum's growing permanent state footprint, where every single-use transaction or ERC-20 transfer leaves a permanent account leaf or storage slot in active state forever. By bringing Bitcoin-style one-shot payments to Ethereum, the proposal aims to reduce the persistent state footprint of simple payment workloads by roughly 99.8%. The proposal relies on EIP-8141 Frame Transactions to package inputs, outputs, account flows, and fee metrics into signed, value-conserving transitions.

Vitalik Proposes State-Minimized Lean Consensus

Proposed by Vitalik Buterin, a design for a Lean consensus upgrade aggressively minimizes beacon chain state requirements by shifting database responsibility to stakers. Instead of the network tracking extensive validator metrics, each node is required to manage their own historic participation data and submit daily zero-knowledge proofs. The model reduces the per-validator footprint on the beacon chain. The proposed mechanism aims to address expensive end-of-epoch processing bottlenecks, which degrade network performance when slot times decrease during single-slot finality.
