The SDK provides a client that can be used to interact with the transmissions protocol. The client is initialized with a configuration object and provides 2 sub-clients for uplink and downlink interactions. The uplink client is used to write data to the protocol, while the downlink client is used to read data from the protocol subgraph.
The api configuration object for the downlink client. This object contains the server url for the subgraph. The default value is the base mainnet subgraph url.
The paymaster configuration object for the wallet client. This object contains the paymaster url for a paymaster proxy. The default value is undefined.
See the paymasters section of the coinbase smart wallet docs.
