Sei Network suffered a $240,000 loss in WSEI tokens following a flash loan attack, as reported by blockchain security firm BlockSec Phalcon. The attack was facilitated by an accidental transfer from wallet "0x9748…a714," which inadvertently provided liquidity for the exploit. The attacker borrowed 1.96 million WSEI tokens through a flash loan and exited without repayment, leaving the funds irrecoverable. This incident underscores the persistent vulnerabilities in decentralized finance (DeFi), where operational errors can lead to significant exploits. The timing of the attack coincides with Sei's upcoming transition to an EVM-only chain in March, prompting the team to advise users to migrate Cosmos-native assets like USDC.n to avoid potential losses. Meanwhile, SEI's price remains under pressure, trading near $0.12, with broader market trends showing bearish signals.
