cannot use (*RPCClient)(nil) (value of type *RPCClient) as multinode.SendTxRPCClient[*"github.com/ethereum/go-ethereum/core/types".Transaction, *SendTxResult] value in variable declaration: *RPCClient does not implement multinode.SendTxRPCClient[*"github.com/ethereum/go-ethereum/core/types".Transaction, *SendTxResult] (wrong type for method SendTransaction)

undefined: multinode.SendTxResult
