Bridges are among the most vital components of the crypto industry's infrastructure, yet they remain vulnerable to attack. Attackers are increasingly targeting message verification and admin controls. Wrapped and bridged assets are still at risk, even if the main chain is safe.A 2025 exploit cost Radiant Capital, a cross-chain lending mechanism, about $50 million. The attack targeted Ethereum's ecosystem, including EVM-compatible networks and cross-chain infrastructure like Arbitrum (ARB) and BNB Chain (BNB). The attacker exploited chain-verification flaws to withdraw funds without collateral.Read also:<a href="https://stocktwits.com/news-articles/markets/cryptocurrency/wall-street-veteran-says-bitcoin-is-entering-its-strongest-regime-yet/cZJjYxrRIMa"> ‘The Strongest Regime For Bitcoin’ Is When CPI Runs Above Short-Term Yields, And A Former Wall Street Strategist Says We're Almost There</a>For updates and corrections, email newsroom[at]stocktwits[dot]com.
