ChainFeeds Research’s PRO issue #153 pulls together a broad set of Bitcoin and Ethereum research updates, led by three themes: a more granular circuit breaker design for Gloas builder markets, a discussion of proprietary AMMs on Ethereum, and a proposal to eliminate part of oracle extractable value through synchronized state transitions. Ethereum researcher Potuz argues that failures in payload delivery should not automatically force validators into self-building, and instead proposes a layered fallback system based on builder trust. Ethereum Foundation researchers Mike Neuder and Maryam Bahrani describe PropAMM as a middle ground between traditional AMMs and RFQ systems, preserving onchain execution while letting professional market makers update pricing parameters more actively. Oraclizer CPTO Jay Kim, meanwhile, frames OEV as a structural timing problem and outlines a model where updates and downstream consequences are bound into a single cross-domain atomic transition. The report also covers a Coldcard hardware signer warning tied to weak seed entropy, two denial-of-service bugs in Core Lightning, a zkPoH concept for proving ownership of at least 1 BTC without exposing specific UTXOs, native randomness sourcing for onchain games, selected items from The MEV Letter #148, and a phishing paper that says transaction simulation itself can become an attack surface.

Resolv Foundation released final compensation plan for March hack: senior USR token gets 1:1 USDC redemption, junior RLP recovers ~60% value. Protocol pivots to tokenized RWA platform Vault Street, launching primeUSD in June 2026.

Resolv’s USR stablecoin suffered a minting exploit that created up to 80 million excess tokens, leading to nearly $25 million in outflows and a sharp depeg to $0.025 before a partial rebound.

Resolv Labs said its collateral pool remains intact after an exploit let an attacker mint about 80 million unbacked USR. The stablecoin fell to $0.14 before rebounding to $0.42, while several DeFi protocols moved to contain exposure.

Resolv Labs update after exploit: 98% of whitelisted redemptions done, non-whitelisted and post-exploit users face delays, RLP holders wait with no timeline, no insider evidence found.

Ethereum's Fusaka upgrade activates on Dec. 3, 2025, bringing PeerDAS data sampling, new gas limits, native passkey support, and L2 scaling improvements, reducing node burden and enhancing security.

Ripple CTO David Schwartz confirmed the activation of the AMMClawback amendment on XRPL mainnet, allowing clawback-enabled tokens like RLUSD to be used in AMM pools. This boosts compliance and liquidity, with the community expecting a significant DeFi growth.

According to an official announcement, Binance will cease support for 23 stock token trading pairs, including AB, ARLP, and BSM, on June 5, 2026, at 19:00 (UTC+8).
