Security Considerations
While developing cross-chain applications using Router's CrossTalk library, there are certain security requirements that need to be adhered to in order to ensure secure cross-chain communication:
  • Ensure that the setup of the linker address and the fee token address is under the control of the owner.
  • Ensure that the sync functions within the contract have the isSelf Modifier set.
  • Ensure that _routerSyncHandler has addressed all the sync functions.
  • Ensure that the correct amount of gas is specified in routerSend functions.
  • Ensure that the source contract address has enough amount of fee token balance and has given the required spending approval to the generic handler.
