• ID-0
  Contract locking ether found:
  Contract NexusBootstrap has payable functions:
  • ModuleManager.receive()
  • ModuleManager.fallback(bytes)
  • NexusBootstrap.initNexusWithSingleValidator(IModule,bytes,IERC7484,address[],uint8)
  • NexusBootstrap.initNexus(BootstrapConfig[],BootstrapConfig[],BootstrapConfig,BootstrapConfig[],IERC7484,address[],uint8)
  • NexusBootstrap.initNexusScoped(BootstrapConfig[],BootstrapConfig,IERC7484,address[],uint8)
    But does not have a function to withdraw the ether
