Expand description

Client implementation for the ChildStateApi RPC API.

Provided Methods§

👎Deprecated since 2.0.0: Please use getKeysPaged with proper paging support

Returns the keys with prefix from a child storage, leave empty to get all the keys

Returns the keys with prefix from a child storage with pagination support. Up to count keys will be returned. If start_key is passed, return next keys in storage in lexicographic order.

Returns a child storage entry at a specific block’s state.

Returns child storage entries for multiple keys at a specific block’s state.

Returns the hash of a child storage entry at a block’s state.

Returns the size of a child storage entry at a block’s state.

Returns proof of storage for child key entries at a specific block’s state.
