-Sometimes you may encounter a `709` error when sending jetton. It says that the value of the toncoin attached to the message is not enough to send it. Make sure that `Toncoin > to_nano(TRANSFER_CONSUMPTION) + forward_ton_amount`. `TRANSFER_CONSUMPTION` in most cases may be 0.037 if the `forward_payload` is not too large. Also don't forget to attach enough `forward_ton_amount` or you can encounter a `cskip_no_gas` error if attached value too small.
