URI Schemes
Litecoin URI schemes simplify the flow of sending and receiving Litecoin by allowing users to click on a link or scan a QR code instead of having to manually enter the transaction details. This URI includes the address, the amount to be sent, and often optional parameters such as a label or message.
BIP21
The BIP21 standard was adopted by Litecoin, but with a different URN denoting litecoin. All wallets are reccomended to adopt this standard, for ease-of-use. Additional information can be found in the spec BIP21 document.
Standard syntax example:
litecoin:<address>[?amount=<amount>][?label=<label>][?message=<message>]
ABFN Grammar:
litecoinurn = "litecoin:" litecoinaddress [ "?" litecoinparams ]
litecoinaddress = *base58/bech32
litecoinparams = litecoinparam [ "&" litecoinparams ]
litecoinparam = [ amountparam / labelparam / messageparam / otherparam / reqparam ]
amountparam = "amount=" *digit [ "." *digit ]
labelparam = "label=" *qchar
messageparam = "message=" *qchar
otherparam = qchar *qchar [ "=" *qchar ]
reqparam = "req-" qchar *qchar [ "=" *qchar ]
BOLT11
The BOLT11 standard specifies the design of a Litecoin lightning invoice. To adapt this invoice as a uri, ltclightning: should be used as
as the URN prefix (note: not 'ltclightning://'). This URI scheme is only followed by versions of lndltc 0.16+.
Example:
ltclightning:lnltc1m1pdtaggcpp5t2a85mvpqvmsyejs3ysa9jqfvzl3fs7tukk8kyvhn64rxumc4t4qdqcd4u47ar9wd697urp09kk2mn5cqzjqxqzuywpn6mhcu4s7fj9q3ndu09805t3q8jwllcd8p2e9plrfcehw3xyr9lpnux9jgcv64mwpvk3599qza6a32uzak2y03ttrgnrmf554ffrgpxnnrk4
Alternatively it may also be useful to set ltclightning: as an additional parameter of a BIP21 payment request. By doing this, wallets
which don't support lightning will be able to fallback to an onchain payment.
Example:
litecoin:<address>?ltclightning:<invoice>
