This page answers some of the common questions about alternative cryptocurrencies - altcoins.
Bitcoin is the only focus of the project and its core developers. However, opt in integrations are present for several altcoins:
BGold (BTG) (also known as Bitcoin Gold)
BPlus (XBC) (also known as Bitcoin Plus)
Liquid Bitcoin (LBTC) (comes with Liquid Tether support USDt) (notes on deployment & usage)
Monero (XMR) (notes on deployment)
Altcoins are maintained by their respective communities.
No. BTCPay developers don't add alternative coins on request. Adding a new coin explicitly depends on the community and developers of those coins. Furthermore, BTCPay developers do not spend excessive time testing nor maintaining the altcoins. If you're submitting a PR for a new coin, make sure that it works. If the altcoin integration is not actively maintained it will be removed from BTCPay.
To add a new coin to BTCPay, please follow the instructions here.
If you want to expand the number of coins in your existing BTCPay Server installation, make sure that you have enough storage space on your machine.
In this example, we only have Bitcoin, and we're adding Litecoin to our docker deployment.
The coin structure:
BTCPAYGEN_CRYPTO1: First supported cryptocurrency (e.g., BTC, LTC. Default: btc)BTCPAYGEN_CRYPTO2: Second supported crypto currency (e.g. btc, ltc. Default: (empty))BTCPAYGEN_CRYPTON: N'th supported crypto currency where N is 9 at maximum. (eg. btc, ltc. Default: (empty))
To add Litecoin, as your second coin (CRYPTO2) do this :
sudo su -export BTCPAYGEN_CRYPTO2="ltc". ./btcpay-setup.sh -i
In the example above we've added Litecoin as the second coin. To remove a particular coin, use the following command:
sudo su -export BTCPAYGEN_CRYPTO2="". ./btcpay-setup.sh -i
Where CRYPTO2 should be replaced with a coin number you wish to remove. If you have an XYZ coin as
BTCPAYGEN_CRYPTO3, and you want to remove it, you should use CRYPT03.
