Start accepting Bitcoin today with BTCPayServer! This guide will walk you through the installation.

One-click deployment

For the easiest and fastest setup, host BTCPayServer on Microsoft Azure:

You can log into Azure with your Microsoft account.

Final installation steps:

• Fill in the options: Resource Group
• Click 'Purchase' to confirm
• (Wait for deployment)
• View the deployment (in Notifications or Resource Groups)
• Verify you can connect to your instance with a browser: https://SERVER-AZURE-DNS/
• At your domain registrar, make sure you have DNS pointing your domain at your Azure deployment's IP.
• Browse to https://SERVER-AZURE-DNS/
• Register a new account (this account will be granted server administrator rights)
• Go to https://SERVER-AZURE-DNS/server/maintenance
• Enter your domain name and click on confirm
• (Wait 1 to 5 minutes)

That's it, you can now browse to https://btcpay.YOUR-DOMAIN/ to create your store!

For advanced users, you can connect via SSH with information on https://btcpay.YOUR-DOMAIN/server/services/ssh, then you can:

• Run docker ps and docker logs xxx to view running processes
• Run btcpay-down.sh and btcpay-up.sh to stop and start the BTCPayServer

This video by Nicolas also demonstrates the above steps:

Approximate Cost (pruned, Bitcoin-only with lightning network): 10 USD per month. You can use the wizard of the lunanode deployment to deploy a BTCPay Server or just use the btcpay-setup.sh -i script as described in this README.

Architecture

As you can see, BTCPay depends on several pieces of infrastructure, mainly:

• A lightweight block explorer (NBXplorer),
• A database (PostgreSQL or SQLite),
• A full node (eg. Bitcoin Core)

There can be more dependencies if you support more than just standard Bitcoin transactions, including:

• C-Lightning
• LitecoinD and other coin daemons
• And more...

Note: The setup process can be time consuming, but is heavily automated to make it a fun and easy experience.

Take a look at how BTCPay works in a video below.

Here is a presentation of the global architecture at Advancing Bitcoin conference.

Full installation (for technical users)

You can also install BTCPayServer on your own machine or VPS instance.

The officially supported setup is driven by Docker (and Docker-Compose).

First, make sure you have a domain name pointing to your host (CNAME), with ports 443 and 80 externally accessible (and perhaps additional ports like 9735 and 9736 for Bitcoin and Litecoin lightning). Otherwise, you will have to set it manually by running changedomain.sh.

Let's assume it is btcpay.EXAMPLE.com.

If you want to support Litecoin, Bitcoin, and C-Lightning, and want HTTPS automatically configured by Nginx:

# Login as root
sudo su -

# Create a folder for BTCPay
mkdir BTCPayServer
cd BTCPayServer

# Clone this repository
git clone https://github.com/btcpayserver/btcpayserver-docker
cd btcpayserver-docker

# Run btcpay-setup.sh with the right parameters
export BTCPAY_HOST="btcpay.EXAMPLE.com"
export NBITCOIN_NETWORK="mainnet"
export BTCPAYGEN_CRYPTO1="btc"
export BTCPAYGEN_CRYPTO2="ltc"
export BTCPAYGEN_REVERSEPROXY="nginx"
export BTCPAYGEN_LIGHTNING="clightning"
. ./btcpay-setup.sh -i

exit

btcpay-setup.sh will then:

• Install Docker
• Install Docker-Compose
• Make sure BTCPay starts at reboot via upstart or systemd
• Setup environment variables to use BTCPay utilities
• Add BTCPay utilities in /usr/bin
• Start BTCPay

You can read the article for step by step instructions.

Environment variables

btcpay-setup.sh will use the following environment variables:

• BTCPAY_HOST: The hostname of your website (eg. btcpay.example.com)

• btcpay-down.sh: Run docker-compose down
• btcpay-setup.sh: Change the settings of your server
• . ./btcpay-setup.sh: Information about additional parameters
• . ./btcpay-setup.sh -i: Set up your BTCPayServer

Under the hood

Generated docker-compose

When you run btcpay-setup.sh, your environment variables are used by build.sh (or build.ps1) to generate a docker-compose adapted for your needs. For the full list of options, see: Environment variables

By default, the generated file is Generated/docker-compose.generated.yml, constructed from the relevant Docker fragments for your setup.

Available BTCPAYGEN_ADDITIONAL_FRAGMENTS currently are:

• opt-save-storage will keep around 1 year of blocks (prune BTC for 100 GB)
• opt-save-storage-s will keep around 6 months of blocks (prune BTC for 50 GB)
• opt-save-storage-xs will keep around 3 months of blocks (prune BTC for 25 GB)
• opt-save-storage-xxs will keep around 2 weeks of blocks (prune BTC for 5 GB) (lightning not supported)
• opt-lnd-autopilot will activate auto pilot on LND. (5 channels, 60% of allocation)
• opt-save-memory will decrease the default dbcache at the expense of longer synchronization time. (Useful if your machine is less than 2GB)
• opt-more-memory will increase the default dbcache to make synchronization faster (Useful if your machine is has around 4GB)
• opt-add-btcqbo will allow you to create an invoice on Quickbooks which include a way for your customer to pay on BTCPay Server (More information on this github repository, this add-on is maintained by JeffVandrewJr, see more on this video)
• opt-add-librepatron, for a self-hosted Patreon alternative backed by BTCPay (More information on this github repository, this add-on is maintained by JeffVandrewJr.
• opt-add-woocommerce, for a self-hosted woocommerce with BTCPay Server plugin pre installed.
• opt-add-tor, for exposing BTCPayServer, Woocommerce, your lightning nodes as hidden services and accept onion peers for your full node. Warning: This options is for working around NAT and firewall problems as well as to help protect your customer's privacy. This will not protect your privacy against a targeted attack against you.
• opt-add-btctransmuter, for a self-hosted IFTTT style service for crypto services such as fiat settlement.

You can also create your own custom fragments.

If you want to add an option to BTCPAYGEN_ADDITIONAL_FRAGMENTS and re-configure your install:

export BTCPAYGEN_ADDITIONAL_FRAGMENTS="$BTCPAYGEN_ADDITIONAL_FRAGMENTS;opt-lnd-autopilot"
. btcpay-setup.sh -i

For example, if you want btc and ltc support with nginx and clightning inside Generated/docker-compose.custom.yml:

Note: The first run might take a while, but following runs are instantaneous.

On Windows (run in powershell):

Invoke-Command {
    $BTCPAYGEN_CRYPTO1="btc"
    $BTCPAYGEN_CRYPTO2="ltc"
    $BTCPAYGEN_REVERSEPROXY="nginx"
    $BTCPAYGEN_LIGHTNING="clightning"
    $BTCPAYGEN_SUBNAME="custom"
    . .\build.ps1
}

On Linux:

BTCPAYGEN_CRYPTO1="btc" \
BTCPAYGEN_CRYPTO2="ltc" \
BTCPAYGEN_REVERSEPROXY="nginx" \
BTCPAYGEN_LIGHTNING="clightning" \
BTCPAYGEN_SUBNAME="custom" \
./build.sh

Next, you will need to configure the runtime environment variables for Generated/docker-compose.custom.yml:

• If you are using NGinx, read this.
• If you are not using NGinx, read this instead.

Again, what does btcpay-setup.sh do?

btcpay-setup.sh is a utility which does the following:

1. Makes sure docker and docker-compose are installed on your system
2. Generates a docker-compose via ./build.sh
3. Sets up an Environment File to configure your docker-compose
4. Sets up environment variables so the tools described in Tooling can work
5. Adds symlinks of those tools into /usr/bin
6. Makes sure BTCPay restarts on reboot via upstart or systemd
7. Starts BTCPay via docker-compose

Overview of files generated by btcpay-setup.sh

if cat $BTCPAY_ENV_FILE &> /dev/null; then
  export $(grep -v '^#' "$BTCPAY_ENV_FILE" | xargs)
fi

/etc/systemd/system/btcpayserver.service ensures that you can control btcpay via systemctl, and that BTCPayServer starts on reboot:

BTCPAY_SSHKEYFILE=/datadir/id_rsa

How can I add an altcoin to BTCPayServer?

1. Add support for your crypto to NBitcoin, NBxplorer, and BTCPayServer. (Use examples from other coins)
2. Create your own docker image (Example for BTC)
3. Create a docker-compose fragment (Example for BTC)
4. Add your CryptoDefinition (Example for BTC)

build.sh is using a pre-built image of the docker-compose generator on docker hub. If you modify the code source of docker-compose generator (for example, the CryptoDefinition Example for BTC), you need to configure build.sh to use your own image by setting the environment variable BTCPAYGEN_DOCKER_IMAGE to btcpayserver/docker-compose-generator:local.

cd docker-compose-generator
BTCPAYGEN_DOCKER_IMAGE="btcpayserver/docker-compose-generator:local"

Or on powershell:

cd docker-compose-generator
$BTCPAYGEN_DOCKER_IMAGE="btcpayserver/docker-compose-generator:local"

Then run ./build.sh or . .\build.ps1. This will generate your docker-compose in the Generated folder, which you can then run and test.

Note that BTCPayServer developers will not spend excessive time testing your image, so make sure it works.

FAQ

How can I modify my environment?

As root, run . btcpay-setup.sh; this will show you the environment variable it is expecting. For example, if you support btc and ltc already, and want to add btg:

export BTCPAYGEN_CRYPTO3='btg'
. btcpay-setup.sh -i

I deployed before btcpay-setup.sh existed (before May 17), can I migrate to this new system?

Yes, run the following commands to update:

sudo su -

cd $DOWNLOAD_ROOT/btcpayserver-docker
git checkout master
git pull
git checkout 9acb5d8067cb5c46f59858137feb699b41ac9f19
btcpay-update.sh
. ./btcpay-setup.sh -i
git checkout master
btcpay-update.sh

exit

I'm getting an error on Windows: Cannot create container for service docker: Mount denied?

If you see this error:

Cannot create container for service docker: b'Mount denied:\nThe source path "\\\\var\\\\run\\\\docker.sock:/var/run/docker.sock"\nis not a valid Windows path'.

Run this in powershell:

$Env:COMPOSE_CONVERT_WINDOWS_PATHS=1

Then, run docker-compose -f EXAMPLE.yml up.

This bug comes from Docker for Windows and is tracked on Github.

How I can prune my node(s)?

This will prune your Bitcoin full node to a maximum of 100GB (of blocks):

export BTCPAYGEN_ADDITIONAL_FRAGMENTS="opt-save-storage"
. ./btcpay-setup.sh -i

Other options are documented here.

How can I customize the generated docker-compose file?

In some instances, you might want to customize your environment in more detail. While you could modify Generated/docker-compose.generated.yml manually, your changes would be overwritten the next time you run btcpay-update.sh.

Luckily, you can leverage BTCPAYGEN_ADDITIONAL_FRAGMENTS for this!

Let's enable pruning to 60 GB, for example:

First, copy opt-save-storage into the the docker fragment folder as opt-save-storage.custom.yml. Important: the file must end with .custom.yml, or there will be git conflicts whenever you run btcpay-update.sh.

Modify the new opt-save-storage.custom.yml file to your taste:

@@ -14,8 +14,7 @@ version: "3"
 services:
   bitcoind:
     environment:
-       BITCOIN_EXTRA_ARGS: prune=100000
+       BITCOIN_EXTRA_ARGS: prune=60000

Then set it up:

export BTCPAYGEN_ADDITIONAL_FRAGMENTS="opt-save-storage.custom"
. ./btcpay-setup.sh -i

Can I run BTCPay Server on ports other than 80 and 443?

You can change the ports for HTTP and HTTPS by setting the environment variables REVERSEPROXY_HTTP_PORT and REVERSEPROXY_HTTPS_PORT. This is handy when ports 80 and 443 are already in use on your host, or you want to offload SSL termination with an existing web proxy.

When you set REVERSEPROXY_HTTP_PORT to another value than 80, the built-in Let's Encrypt certificate will not work, as Let's Encrypt will try to validate your SSL certificate request by connecting from the internet to your domain on port 80. This validation request should be able to reach BTCPay Server in order to receive the certificate.

If you need to run on a different port, it's best to terminate SSL using another web proxy and foreard your traffic.

Can I offload HTTPS termination?

Yes. To offload SSL termination, just forward the requests to the port specified by REVERSEPROXY_HTTP_PORT and make sure you are setting the header X-Forwarded-Proto: https so BTC Pay Server can know the original request was HTTPS. If you forget this extra header, BTCPay Server will work, but it will believe the connection is insecure and display a warning message.

Because you are offloading HTTPS, you won't need the built-in Let's Encrypt anymore and can exclude nginx-https by adding it to BTCPAYGEN_EXCLUDE_FRAGMENTS.
