[Reminder] Kaia v2.2.2 Hardfork is coming on Apr 7. The bytecode at address(0) will be removed. After the upgrade, address(0) will behave as a regular EOA. What changes: • Calls to address(0) → succeed (currently reverts) • isContract(address(0)) → false • KAIA transfers to address(0) → succeed Most apps won't be affected, but if your contracts depend on the previous behavior of address(0), review and update before the hardfork.
