polkadot-api-patterns
Essential patterns for polkadot-api (PAPI) development. Use when implementing blockchain interactions with Polkadot/Substrate chains including transactions (signing, batching, watching), queries (storage, multi-key), observables (lifecycle tracking), type handling (MultiAddress, Binary), client setup, or debugging PAPI code. Critical for preventing the common mistake of using @polkadot/api (PJS) instead of polkadot-api (PAPI). Load whenever user mentions polkadot-api, blockchain transactions, pallet calls, or needs to fix PAPI-related type errors.
