# @polkadot/api-provider
|
|
|
|
Generic transport providers to handle the transport of method calls to and from Polkadot clients from applications interacting with it. Generally, unless you are operating at a low-level and taking care of encoding and decoding of parameters/results, it won't be directly used. API interfaces building on top these providers can support various transports with the same underlying interfaces.
