Vitalik Buterin has decided to spin out the Ethereum Foundation's ecosystem development arm as a separate entity. The decision was made several weeks ago and reportedly signaled in a public tweet before being communicated internally at EF roughly one week ago. The structural details of the spinout remain unsettled, though there are rumors of a merger with the Enterprise Ethereum Alliance and staffing changes, leaving open questions about funding, governance, and the division of responsibilities between the new entity and the Foundation.

At his Senate Banking Committee hearing, Fed chair nominee Kevin Warsh said digital assets are already embedded in US finance and should be incorporated into the financial system with consumer protections, signaling a more crypto-friendly posture at the central bank while rejecting a US CBDC as bad policy. The hearing also emphasized the political tension around the nomination, with Elizabeth Warren warning against Fed independence being compromised and Warsh's disclosed crypto investments adding to scrutiny over how he might approach the industry if confirmed.

Coinbase expanded its crypto-backed USDC lending service to UK users, enabling borrowing of up to $5M against Bitcoin collateral and up to $1M against ETH or cbETH, with loans routed through Morpho on Base. Rates are variable and recalculated each block, with no fixed repayment schedule, though LTV breaches trigger liquidation. The move follows Coinbase's February 2025 FCA registration and complements recent UK product additions including DEX trading and savings accounts, with the company having originated $2.17B in USDC loans as of April 14.

Base Azul launches May 13, introducing multiproofs for faster withdrawals and Stage 2 decentralization. The upgrade consolidates the stack onto base-reth-node and base-consensus, aligns with Ethereum Osaka specs, and includes a $250,000 Immunefi audit competition to ensure network security and reliability for developers and node operators.

a16z Crypto maps five blockchain use cases for the AI agent economy, arguing that as agents become autonomous economic actors, gaps in identity, governance, payments, trust verification, and user control require infrastructure that traditional rails cannot provide. On the payments front, Stripe and Tempo's MPP marketplace cleared 34,000+ agent-to-agent transactions in its first week at fees as low as $0.003, while x402 processes roughly $1.6M monthly in agent-driven payments, with headless merchants proving difficult for conventional processors to underwrite. Scoped delegation frameworks from MetaMask, Coinbase AgentKit, and Merit Systems let users define agent permissions at the smart contract level, and NEAR Intents has handled over $15B in cumulative DEX volume since Q4 2024.

This post proposes a pragmatic roadmap to secure Bitcoin against Cryptographically Relevant Quantum Computers. By implementing P2MR and new signature opcodes via soft forks, users can proactively migrate to quantum-safe outputs. This incremental approach prioritizes immediate, low-risk mitigations while deferring complex, high-stakes decisions regarding legacy coin security.

Prediction markets reached $6.5B in combined weekly volume across Polymarket and Kalshi in April, but the CLOB architecture concentrating that growth also limits it: Kalshi's top 3 market makers supply 70% of election contract liquidity, leaving thousands of long-tail markets in entertainment, science, and culture without support. The result is 85-90% of prediction market volume locked to politics and sports, while ~$550M in total TVL sits disconnected from the $100B in DeFi capital deployed in lending and yield protocols. AMM-style permissionless infrastructure where the first participant bootstraps liquidity for the second removes the professional market maker requirement that currently gates new market creation.

DoorDash is integrating the Stripe-backed Tempo blockchain to facilitate stablecoin payouts for its global merchant network. This move aims to replace fragmented payment rails, leveraging a $300 billion stablecoin market to improve settlement speed and reduce costs for cross-border transactions across DoorDash's 40-country operational footprint.

Ripple laid out a plan to make the XRP Ledger quantum-ready by 2028.

Tether disclosed a 1.95 million-share stake in bitcoin mining lender Antalpha, giving it about 8.2% of the company after its IPO and signaling continued appetite for infrastructure bets tied to mining finance.

MicroStrategy added 34,164 BTC for $2.54 billion between April 13-19, its third-largest single purchase by coin count, pushing total holdings to 815,061 BTC at a cumulative cost of $61.56 billion.

Revolut's onchain crypto transfer volume has climbed from near zero in late 2022 to a sustained $1B-$1.8B per month by 2026.
