Note

Refactors RPC handling to a strategy-based router that defaults to wallet passthrough, removes direct Infura/readonly fetch logic, adds a routing strategy module, and updates/adjusts tests (including skipping a readonly RPC test).

• Core RPC Refactor:
  • Introduce RequestHandlingStrategy with WALLET, RPC, and SDK routes via multichain/rpc/strategy.ts.
  • Rework RPCClient.invokeMethod to route by strategy; implement wallet passthrough and stub handlers for RPC/SDK.
  • Remove direct readonly RPC fetching, Infura URL/header handling, and related code paths.
  • Reduce deeplink open delay from 250ms to 10ms in wallet handling.
• Tests:
  • Rewrite multichain/rpc/client.test.ts to validate wallet routing and error handling; drop tests for fetch/headers/readonly RPC behavior.
  • In invoke.test.ts, skip the readonly RPC client test pending RPC node routing and keep other invoke error/success paths.
• Misc:
  • Internal imports adjusted to new module locations (e.g., config/logger).
