I'm trying to get the payees public key (destination node) from the payment request. You can see an example here.
In the source code for (https://lightningdecoder.com/) it seems like they get it from a tag or tag 19 (?) but I can't find this information in the decoded payment requests i get from LND:
Does any one know how to get this? Preferably using Go and the invoice returned by LND
Here is the solution I ended up using:
// var invoice *lnrpc.Invoice
inva, err := zpay32.Decode(invoice.PaymentRequest, &chaincfg.MainNetParams)
if err != nil { return err
}
fmt.Sprintf("%x", inva.Destination.SerializeCompressed())Alternatively, I think you can replace the fmt.Sprintf with hex.EncodeToString
hex.EncodeToString(inva.Destination.SerializeCompressed())
