- Installation (short!)
- Contributions welcomed
Satsale can be used as a
- Donation page and button for your website that you can easily embed/link to anywhere.
- Bitcoin payment gateway, including a Woocommerce plugin that easily turns any Wordpress site into a Bitcoin accepting store.
- Versatile API and payments platform for both on-chain and lightning payments (supporting both clightning and lnd).
Compared to other Bitcoin payment processors, SatSale is lightweight, easy to install and self-host. SatSale is also a great building block for python lightning applications.
SatSale makes donation buttons simple - an easy copy and paste of the one line HTML iframe into your site.
SatSale can talk to your own Bitcoin node, and verify payments with your own copy of the blockchain. Payments go directly into your wallet with no third party.
- Connect SatSale to your node, or you can rely on someone else's with just your extended public key.
- Supports both clightning and lnd, or you can just use on-chain!
- Direct peer-to-peer payments without any middleman. No KYC, and greater privacy than donation systems where Bitcoin addresses are reused multiple times.
- Lightning Address support (e.g. firstname.lastname@example.org)
- Lightweight and highly extendable, with basic html and css styling and a modular Python backend. Take a look at the code or lnd.py!
- Reusable and extendable API.
- No shitcoins. Bitcoin only.
Clone and install dependencies
git clone https://github.com/nickfarrow/SatSale cd SatSale/ pip3 install -r requirements.txt
You should run a Bitcoin node, but if you don't or just want to try SatSale, you can simply use the
xpub payment method (your extended public key is usually found in your Bitcoin wallet info).
config.toml and replace
payment_methods = ["bitcoind"] with:
payment_methods = ["xpub"]
then edit the xpub configuration:
[xpub] xpub = "xpub..." bip = "BIP84"
You should strongly consider running a node and using it to verify payments rather than trusting block explorers..
When starting SatSale for this first time you must check the address matches one in your wallet to confirm you have used the expected address
bip and derivation path.
config.toml configuration and point to your Bitcoin node:
[bitcoind] host = "127.0.0.1" username = "bitcoinrpc" password = "rpcpassword" rpcport = "8332" wallet = ""
(You can find these in
When connecting to a remote node, you will need to connect to the SSH
tunnel_host for to a node like
"pi@IP", ensuring you have SSH keys in
ufw allow 8332 the appropriate ports to connect to your node. Or alternatively, see tor hidden service.
Run SatSale with
gunicorn -w 1 -b 0.0.0.0:8000 satsale:app
That's it! You should now be able to view your SatSale server at
http://YOUR_SERVER_IP:8000/. If running locally, this will be
If running on a Raspberry Pi, you will want to forward port 8000 in your router settings so that SatSale is also visible at your external IP address. You might have to allow gunicorn through your firewall with
sudo ufw allow 8000.
You will want to run gunicorn with nohup so it continues serving in the background:
nohup gunicorn -w 1 0.0.0.0:8000 satsale:app > log.txt 2>&1 & tail -f log.txt
Tip: you can a particular config file with
gunicorn -w 1 0.0.0.0:8000 satsale:app -- config.toml
Now embed the donation button into your website HTML:
<iframe src="http://YOUR_SERVER_IP:8000/" style="margin: 0 auto;display:block;width:420px;height:460px;border:none;overflow:hidden;" scrolling="no" ></iframe>
YOUR_SERVER_IP to the IP address of the machine you're running SatSale on, node or otherwise. Additionally, you could redirect a domain to that IP and use that instead.
Point a domain to your VPS. You can run SatSale or use NGINX/apache to point to the service. See HTTPS instructions. Embedded iframes are easy if your site only uses HTTP. But if your site uses HTTPS, then you can see your donation button at
http://YOUR_SERVER_IP:8000/ but will not be able to in an embedded iframe. See HTTPS instructions.
Once you have an HTTPS domain pointed at SatSale, in the configuration under a lightning node you can specify a lightning address:
# Lightning Address e.g. email@example.com (think this requires https url) lightning_address = firstname.lastname@example.org lightning_address_comment = "Thank you for your support <3"
Run SatSale on a separate machine to your node, ensuring your node IP is not exposed.
When possible, host on a machine where your node only has access to a watch-only wallet.
Similarly, for lightning, use an
admin.macaroon unless required.
Currently we have a plugin for Woocommerce in Wordpress that makes Bitcoin webstores extremely easy, please click here for installation instructions. SatSale acts as a custom payment gateway for Woocommerce via the php plugin found in
/gateways. We have plans to extend to other web stores in the future.
When updating we recommend to first backup your config:
cp config.toml bk_config.toml # (previously) cp config.py bk_config.py
then stash your changes:
git stash git pull origin master git stash pop
We're still in early development, so things are changing a lot. You may have to resolve changes or manually migrate to the
.toml (if you used an earlier version of SatSale with the
You can also just make commits to your modified fork.
The main code can be found in satsale.py. The client-side logic for initiating the payment and querying the API sits in static/satsale.js, button appearance in templates/index.html, and Woocommerce plugin in gateways/woo_satsale.php. Please have ago at implementing some of the things below or in the issues!
SatSale is in early development. As such, we are not responsible for any loss of funds, vulnerabilities with software, or any other grievances which may arise. Always confirm large payments manually and use cold storage as much as possible.
Please consider supporting me via my own instance of SatSale :). This is my first FOSS project, any support would greatly assist my ability to prioritise SatSale and other areas of Bitcoin. And most importantly, help us bring non-custodial bitcoin payments to the world. Please email
