Scheduled for Mar 30, 11:00 - 19:00 UTC

Scheduled

We are upgrading our Kaia node to v2.2.2. During the maintenance window, brief interruptions to RPC availability may occur. This release also includes cryptography bug fixes and performance improvements.

RPC Changes

Zero address (0x0) — modified The account at address 0x0 is being converted from a contract account to an EOA. Any calls to 0x0 that previously executed bytecode will no longer do so after the hardfork. Applications interacting with or targeting 0x0 as a contract should be updated accordingly.
