ChainCatcher 消息，自称为“白帽黑客”的攻击者从 Liquid Network 提取约 4000 枚 BTC 后，已于周一将其中 3400 枚 BTC（约 2.692 亿美元）归还至该侧链的联邦钱包，追回约 85% 的资金。事件始于周日，一名客户向 SideSwap 的 peg-out 服务发送了 4000 枚 L-BTC。 攻击者通过比特币交易消息自称“白帽黑客”，并要求先修复漏洞。Blockstream 随后发送签名消息称“桥接节点已修补，可以安全归还资金”，攻击者随即转账。尽管如此，仍有约 598.5 枚 BTC（约 4700 万美元）留在相关地址。 Ledger 首席技术官 Charles Guillemet 对“白帽”说法表示怀疑，称若这是链上加密合约下的协商奖励，看起来更像勒索。Liquid 已禁用桥接节点并要求交易所暂停 L-BTC 存取款，但尚未公布剩余资金处理方案及恢复正常运营的时间。
