ETHEREUM LABELED 'STANDOUT' AS CRYPTO FUNDS ADD $785 MILLION IN FIFTH STRAIGHT WEEK OF INFLOWS

Crypto investment products saw $785 million in inflows last week, marking the fifth consecutive week of gains. Ethereum was labeled the “standout performer” after adding $205 million (the strongest showing this year). The uptick reflects renewed investor confidence following Ethereum's Pectra upgrade and leadership changes, even as U.S. spot ETH ETFs contributed just $41.8 million.

STRATEGY ADDS 7,390 BTC FOR $765M

Strategy (formerly MicroStrategy) acquired 7,390 BTC for approximately $765 million at an average price just under $103,500 as bitcoin climbed past $100 K, lifting its year-to-date bitcoin yield to 16.3% and bringing its total holdings to 576,230 BTC purchased at an average cost of $69,726. At today's prices, those holdings are worth over $59.2 billion, representing an unrealized gain of $19.2 billion (47%). In a concurrent SEC filing, Strategy disclosed a class-action lawsuit in the Eastern District of Virginia accusing its executives of misleading investors about the profitability and risks of its bitcoin-focused strategy.

02INNOVATION & LAUNCHES

ENDGAME: MAXING PERFORMANCE WITH LOW NODE SPECS

MegaETH tackles the scalability bottleneck of redundant work by dividing network roles into four specialized node types: Sequencers that hold state in RAM and produce 10 ms blocks, lightweight Provers that generate cryptographic proofs asynchronously, resource‑efficient Replicas that apply state diffs and verify them via proofs, and optional Full Nodes that re‑execute blocks for maximum trustlessness. This architecture eliminates the need for every node to perform every task, achieving 1.7 Gigagas/s throughput today without pricing out smaller participants thanks to minimal hardware requirements for Prover and Replica nodes. Sequencer rotation among a set of builders preserves decentralization, while Full Nodes offer a trust anchor for critical applications. MegaETH's long-term goal is 1ms block times and over 10 Gigagas/s capacity.

INTRODUCING COINBASE DEVELOPER PLATFORM WALLET POLICIES

CDP's new policy engine allows wallets to filter transactions to a restricted set of addresses, limit access to known smart contracts, and enforce per-address transaction limits. Combining the policies with AgentKit enables a spectrum of guardrail strength for ensuring agents have autonomy to the degree a human is comfortable with. CDP's wallet product is now a leading solution for building programmable, server-side wallets with applications including neobanks, AI agents, and embedded experiences.

03GUIDES & TUTORIALS

A LOCAL-NODE-FAVORING DELTA TO THE SCALING ROADMAP

Vitalik Buterin has outlined a refinement to Ethereum's scaling roadmap that preserves the ability to run personal full nodes despite rising L1 gas limits. “Partially stateless nodes” verify blocks without storing the full state, keeping only user-specified data. This enables private, censorship-resistant, and trustless local access to the chain. Short-term priorities include fully rolling out EIP-4444, building erasure-coded distributed history, and repricing storage-heavy opcodes to lower the barrier for node operation in a more data-intensive future.

THE CRYPTO OPSEC BIBLE

Web2 attack vectors like social engineering, key leakage, supply‑chain exploits account for over three times the value lost to smart‑contract bugs ($3.31 billion vs. $983 million since January 2023), driven by poor DevOps, phishing, and lax device/key management. A paranoid “Don't Trust, Verify” mindset, strict phishing education, hardware‑key 2FA, sandboxed code execution, and rigorous password/key rotation are critical for thwarting threats ranging from script kiddies to nation‑state actors. This guide includes platform‑specific best practices for Twitter, Telegram, Discord, Slack, Google Workspace, GitHub, cloud environments, and multisigs, plus physical security measures against tailgating and device compromise.

SEEKING CLEAR, COMMON SENSE STABLECOIN REGS

Bipartisan sponsors designed the GENIUS Act to establish a pro-growth federal stablecoin framework. It requires fully backed, privately issued “digital dollars” to maintain U.S. Dollar primacy, cut payment costs for families and small businesses, and direct fintech investment to American communities. Progressive advocacy groups like Americans for Financial Reform and Better Markets instead pressured the SEC under Chair Gensler toward enforcement-first crypto regulation, leading to high-profile policy missteps and disenchantment among crypto-savvy voters. Their behind-the-scenes influence derailed early congressional hearings and favored enforcement over transparent rulemaking, alienating a key constituency in the 2024 election.

AN ARGUMENT FOR DROPPING PERMIT2

With EIP-7702 now live, developers would like permit2 (Uniswap-created workaround for gasless token approvals) to be retired because of its added security risks and implementation complexity. Unlike permit2, which required broad approvals and was prone to multi-asset abuse via a single signature, EIP-7702 enables clean batch transactions without added smart contract code. Though adoption will take time, 7702 offers a more secure and streamlined path forward, making permit2 redundant.
