Making requests

Requests to Coinbase Wallet can be made by calling the makeRequest function provided by the SDK. This function also accepts a list of actions.

val signTypedDataV3 = Web3JsonRPC.SignTypedDataV3(
   "0xCD2a3d9F938E13CD947Ec05AbC7FE734Df8DD826", // address
   "" // typed data JSON
).action()
val requestActions = listOf(signTypedDataV3)

client.makeRequest(request = RequestContent.Request(actions = requestActions)) { result ->
   result.fold(
       onSuccess = { returnValues ->
           returnValues.handleSuccess("Request", requestActions)
       },
       onFailure = { err ->
           err.handleError("Request")
       }
   )
}

Batch requests

The client supports sending multiple actions as a single batch request.

For example, the code below will make requests for a user account and to switch chains:

val requestAccounts = Web3JsonRPC.RequestAccounts().action()
val switchEthereumChain = Web3JsonRPC.SwitchEthereumChain(
   chainId = "1666600000"
).action()
val requestActions = listOf(requestAccounts, switchEthereumChain)

client.makeRequest(request = RequestContent.Request(actions = requestActions)) { result ->
   result.fold(
       onSuccess = { returnValues ->
           returnValues.handleSuccess("Request", requestActions)
       },
       onFailure = { err ->
           err.handleError("Request")
       }
   )
}

An example request is provided in the sample application.
