ensureInitialized

ensureInitialized(): void
Ensures that the provider has been initialized before use.

Returns void
Throws
Error if not initialized
Inherited from BaseProvider.ensureInitialized
- Defined in src/core/provider/BaseProvider.ts:291

getCapabilities

getCapabilities(): Partial<CapabilityMap>
Returns Partial<CapabilityMap>
Inherited from BaseProvider.getCapabilities
- Defined in src/core/provider/BaseProvider.ts:79

getCapability

getCapability<C extends CapabilityKeyType>(
capability: C,
): C extends keyof CapabilityMap ? CapabilityMap[C] : ProviderCapability
Type Parameters
- C extends CapabilityKeyType
