Returns the wrapped ContractClient with a curated subset of transaction methods: fundCAddress, fundCAddressWithSwap, withdrawFees, setFee, setFeeCollector, setAdmin, and upgrade.
For the full set of SDK methods (batch operations, cross-chain, relayers, paginated queries, etc.), use OnboardingBridgeSDK directly.
CachedContractClient caches a small set of view methods while delegating all transaction logic to the underlying OnboardingBridge SDK implementation.
