The US Senate advanced a war-powers resolution on Tuesday that could require President Donald Trump to obtain congressional approval to continue the war with Iran, after a procedural vote passed 50–47. Analysts quoted in the report said the signal may modestly support risk assets, while Bitcoin was roughly flat around $76,500 over the past 24 hours.

Echo Protocol said Tuesday it is investigating a security incident affecting its Echo bridge on Monad and has suspended all cross-chain transactions after about 1,000 unauthorized eBTC was minted. The attacker moved part of the proceeds through Curvance and ultimately sent 384 ETH to Tornado Cash, while still holding 955 eBTC, according to DeBank.

Fundstrat co-founder Tom Lee said on Monday that Ether has faced sustained selling pressure over the past three months as crude prices climbed. He cited a record-high inverse correlation, noting oil has risen 66% from $65 to above $100 per barrel since Feb. 28 and that ETH slid nearly 10% over the past week to about $2,100 on Monday.

Analysts are debating whether Bitcoin could see another sharp May sell-off in 2026, echoing declines that followed US mid-term election years in 2018 and 2022. Bitcoin was around $76,900 at the time of writing, down 5.6% over the past seven days, as some warn of capitulation risks below $78,000 while others argue market structure changes may limit drawdowns.

The Ethereum Foundation has set a 200 million gas limit floor and finalized EIP-8037 as part of its Glamsterdam upgrade, after previously scheduling the upgrade for June and now expecting it in Q3 2026.

The Solana Foundation said on Monday it introduced STRIDE, a security auditing and monitoring program for Solana-based DeFi protocols, alongside the Solana Incident Response Network for real-time coordination. STRIDE assesses projects across eight areas such as program security, governance controls, operational security, and incident response, with results intended to be published publicly. The update follows a reported ~$280 million loss at Drift Protocol after a social-engineering attack tied to North Korean-linked actors.

MetaMask developer and security researcher Taylor Monahan said North Korean IT workers have been embedded in crypto companies and DeFi projects for at least seven years, alleging involvement across 40+ DeFi platforms. Her comments followed Drift Protocol's statement of "medium-high confidence" that its recent $280 million exploit was conducted by a North Korea state-affiliated group.

Crypto prices rose as US President Donald Trump issued mixed messages on Iran and the Strait of Hormuz, including a new deadline he suggested runs until Tuesday.

The move triggered roughly $255 million in liquidations over 24 hours, with 73% tied to short positions.
