[Urgent] Sonic - Mainnet - Upgrade to v2.2.5

Scheduled for Oct 12, 00:00 - 23:59 UTC

Scheduled

We are upgrading our Sonic Mainnet infrastructure to v2.2.5 on 2026-10-12. This is a stability release that hardens the security posture of publicly exposed RPC nodes by restricting custom JavaScript tracers in debug methods. Brief interruptions to RPC availability may occur on that date.

RPC Changes:
debug_trace* — Custom JavaScript tracers are now rejected by default with a `custom tracer is not permitted` error. Built-in tracers continue to work without configuration changes.
