Methods

​
readCallFunction()

Call a read-only function on a deployed contract. Signature: 
readCallFunction(
  networkId: string,
  contractAddress: string,
  request: ReadCallFunctionRequest,
  requestOptions?: RequestOptions
): Promise<ReadCallFunctionResponse>
Parameters:
ParameterTypeRequiredDescription
networkIdstringYesNetwork ID (UUID from getNetworks())
contractAddressstringYesContract address
request.abiFunctionobjectYesABI function object
Example Request: 
const result = await client.contractInteractions.readCallFunction('your-network-id', '0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb', {
  abiFunction: {
    name: 'balanceOf',
    type: 'function',
    inputs: [
      { name: 'owner', type: 'address' }
    ],
    outputs: [
      { name: '', type: 'uint256' }
    ]
  }
});
Example Response: 
{
  data: {
    result: {
      data: {
        result: {
          // Decoded function result
        },
        functionName: 'balanceOf',
        contractAddress: '0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb',
        network: 'ETH',
        encodedData: '0x1234567890abcdef...'
      },
      success: true,
      status: 200
    }
  }
}

  addressId: 'address-id',
  clientShare: 'your-client-share',
  abiFunction: {
    name: 'transfer',
    type: 'function',
    inputs: [
      { name: 'to', type: 'address' },

      workflowId: 'workflow-id-here',
      operationId: 'write-call-id-here',
      status: 'started',
      message: 'Write call workflow started'
    }
  }
}
Response Fields:
FieldTypeRequiredDescription

console.log('Workflow ID:', result.data.workflowResult.workflowId);

​
getTransactionReceipt()

Get transaction receipt for a transaction hash. Signature: 
getTransactionReceipt(
  networkId: string,
  txId: string,
  requestOptions?: RequestOptions
): Promise<TransactionReceiptResponse>
Parameters:
