On February 2 2026, CrossCurve disclosed that its cross-chain bridge smart contracts had been exploited, causing about $3 million in losses across several blockchain networks. A message verification flaw reportedly enabled attackers to spoof cross-chain messages and unlock tokens without proper authorization. The project has urged users to stop interacting with its contracts and its CEO has offered a bounty of up to 10% if the stolen funds are returned within 72 hours.

CrossCurve said on X late on Sunday that its cross-chain bridge was under attack and asked users to stop interacting with the protocol while it investigates a smart contract issue. Security account Defimon Alerts estimated around $3 million was taken across several networks, and partner Curve Finance told those with CrossCurve pool allocations to review positions and consider removing votes.

On February 1, 2026, Base said its Ethereum Layer‑2 saw intermittent slowdowns in transaction processing, while block production continued.

On January 11, South Korea announced the end of a nine‑year ban on corporate crypto investing, and, as of February 1, 2026, regulators were weighing a 10% equity cap for listed firms and professional investors, up from 5%.

A single wallet lost 4,556 ETH, worth about $12.25 million, in an address poisoning incident.
