Ethereum recorded more than 700,000 failed transactions on March 22, lifting the failure rate above 35% even as overall usage cooled. The pattern suggests execution issues are persisting beyond simple congestion, potentially raising costs and reducing user confidence. While participation remains visible in address activity, rising complexity and reliability concerns may be weighing on deeper engagement.

Drift Protocol said the exploit discovered on Wednesday caused losses of about $280 million, based on external estimates, and described it as a coordinated operation that unfolded over roughly six months. The team said it has “medium-high confidence” the same actors were behind Radiant Capital’s $58 million October 2024 hack, and it is working with law enforcement to reconstruct what happened during the April 1 attack.

Solana co-founder Anatoly Yakovenko described the Drift Protocol incident as "terrifying" after details pointed to a long-running, in-person social engineering operation. Drift Protocol was drained of $270 million and then halted deposits and withdrawals while warning users it was not an April Fools' joke. The report says the attackers built trust from late 2025 through March 2026 before delivering malicious links and software to contributors.

Fed funds futures tracked by the CME FedWatch Tool imply a 99.5% chance the Federal Reserve keeps rates at 3.50%-3.75% at the April 29 FOMC meeting. The repricing follows WTI moving above $110 per barrel and Brent settling above $107 amid the reported U.S.-Israel conflict with Iran, while prediction markets lift the probability of zero 2026 cuts to 36% on Polymarket and 38.5% on Kalshi. Markets also assign a 96.7% probability of another hold at the June 17 meeting.

SIREN has rebounded sharply from recent lows, with the token rising about 100% after earlier swings that included a 1600% early-March jump followed by an 88% pullback and an additional 70% drop this month. The move is described as a relief bounce from oversold conditions rather than a fundamentals-led reversal, with $0.60–$0.65 marked as the key resistance zone. Analysts say a sustained break above $0.65 could open a retest of $0.8–$1.0, while rejection may send price back toward $0.45–$0.30.

Santiment said bearish discussion about Bitcoin on social media has risen to its highest level since late February, a setup it argues can precede a price rebound. On Saturday, the bullish-to-bearish comment ratio was 0.81, and Bitcoin traded around $67,100 at publication time after falling 5.53% over the past 30 days. The Crypto Fear & Greed Index remained in "Extreme Fear", with a score of 12 on Sunday.

Japan's Financial Services Agency (FSA) is advancing a regulatory overhaul that would shift crypto assets toward a financial-instruments framework and tighten investor-protection rules. The plan, based on findings published in February 2026, includes stronger disclosures, broader supervision of crypto businesses, and crypto-specific insider-trading restrictions as legislation moves through parliament.

Altcoin traders are watching Bitcoin dominance fail to clear the 60% area, a setup that has historically preceded sharp reversals. This cycle, ETH/BTC is down nearly 10% year-to-date despite ETH staking reaching 31.6% of supply, while SOL-related metrics and ETF flows have looked comparatively firmer. If SOL/BTC starts to recover as BTC.D weakens, markets may interpret it as an early signal of a SOL-led altcoin push.
