ChainCatcher 消息，跨链协议 Axelar Network 针对近期 Secret Network 相关安全事件发布说明称，社区对事件存在误解，Axelar 和 Inter-Blockchain Communication Protocol (IBC) 均未遭到攻击或破坏，受影响的代币智能合约并非由 Axelar 开发、部署或维护，Axelar 的防火墙机制也阻止了影响进一步扩散至其他链。
据悉，遭利用的合约是基于 CW20-ICS20 实现的一个分叉版本，但开发者移除了两项核心安全检查，导致出现“无限铸造”漏洞。由于删除了原本用于防止此类问题的校验机制，该分叉改变了合约原有信任模型，同时未经过新的安全审计。
Axelar Network 解释称，任何人都可以通过 IBC 部署用于跨链资产封装的合约，同类合约也被用于将其他链代币封装至 Secret Network。但此次事件中的 Secret 侧分叉版本因删除关键安全检查而存在漏洞，此次事件并非特有逻辑缺陷，也不是 IBC 协议本身的问题，而是第三方合约修改后引入的安全风险。
