Note

Medium Risk
Breaking constructor API plus new remote config fetch on wallet startup. Duplicate messenger registration can fail existing consumers that already wire these controllers.

Overview
BREAKING: Default wallet init now constructs ConfigRegistryApiService and ConfigRegistryController, so remote config registry is part of the core wallet graph.

instanceOptions.configRegistryApiService is required (env, optional fetch / policyOptions). configRegistryController is optional (pollingInterval, fallbackConfig). The controller messenger delegates keyring, remote feature flags, and ConfigRegistryApiService:fetchConfig.

Consumers that already register these on a custom root messenger must drop their own wiring or registrations will collide. wallet-cli passes ConfigRegistryApiEnv.PRD.

Is it intentional to always hit prod, even locally? Why not require clients to pass this in instead of having the Wallet Library default this?

[mikesposito]

The idea was to preserve the optionality, but we can make it a mandatory option

One more thing.

I don't know if I like this either, but at least it's consistent with the defaults wallet-cli uses for other controllers/services (i.e. it uses prod for other APIs).

Looks good!
