git clone https:/basicswap/basicswap.git

Run Using Docker

Install dependencies:

apt-get install curl jq git

Docker must be installed and started:

docker -v

Should return a line containing Docker version...

To install docker engine on your platform see:

https://docs.docker.com/engine/install/#server

It's recommended to setup docker to work without sudo.
Without this step you will need to preface each docker-compose command with sudo:

https://docs.docker.com/engine/install/linux-postinstall/

Copy the default environment file:

cd basicswap/docker
cp example.env .env

(Optional) Set custom coin data path:

Coin-related files, such as blockchain and wallet files, are stored in /var/data/coinswaps by default. To use a different location, simply modify the target path in your .env file found within the /docker sub-folder.

cd basicswap/docker
nano .env

Create the images:

cd basicswap/docker
docker-compose build

Depending on your environment, the docker-compose command may not work. If that's the case, type docker compose instead, without the dash.

Prepare the datadir:

Set xmrrestoreheight to the current xmr chain height.

CURRENT_XMR_HEIGHT=$(curl https://localmonero.co/blocks/api/get_stats | jq .height)

Adjust --withcoins and --withoutcoins as desired, eg: --withcoins=monero,bitcoin. By default only Particl is loaded.

FastSync

Append --usebtcfastsync to the below command to optionally initialise the Bitcoin datadir with a chain snapshot from btcpayserver FastSync.
FastSync README.md

Setup with a local Monero daemon (recommended):

docker-compose run --rm swapclient basicswap-prepare --datadir=/coindata --withcoins=monero --htmlhost="0.0.0.0" --wshost="0.0.0.0" --xmrrestoreheight=$CURRENT_XMR_HEIGHT

To instead use Monero public nodes and not run a local Monero daemon
(it can be difficult to find reliable public nodes):

Set XMR_RPC_HOST and BASE_XMR_RPC_PORT to a public XMR node.
docker-compose run --rm -e XMR_RPC_HOST="node.xmr.to" -e BASE_XMR_RPC_PORT=18081 swapclient basicswap-prepare --datadir=/coindata --withcoins=monero --htmlhost="0.0.0.0" --wshost="0.0.0.0" --xmrrestoreheight=$CURRENT_XMR_HEIGHT

Record the mnemonic from the output of the above command. Mnemonics should be stored encrypted and/or air-gapped. And the output of echo $CURRENT_XMR_HEIGHT for use if you need to later restore your wallet.

Set the timezone (optional):

Edit the .env file in the docker directory, set TZ to your local timezone. Valid options can be listed with: timedatectl list-timezones

Start the container:

docker-compose up

Open in browser: http://localhost:12700

Add a coin

docker-compose stop
docker-compose run --rm swapclient basicswap-prepare --datadir=/coindata --addcoin=bitcoin --usebtcfastsync

You can copy an existing pruned datadir (excluding bitcoin.conf and any wallets) over to $COINDATA_PATH/bitcoin Remove any existing wallets after copying over a pruned chain or the Bitcoin daemon won't start.

With Encryption

docker-compose run --rm -e WALLET_ENCRYPTION_PWD=passwordhere swapclient basicswap-prepare --datadir=/coindata --addcoin=bitcoin --usebtcfastsync

Windows

Setup WSL 2 and Docker Desktop

docs.docker.com/docker-for-windows/wsl

Open a wsl terminal Windows key + R -> "wsl" -> Enter

Install Git:

sudo apt update
sudo apt install git

Download the BasicSwap code:

git clone https:/basicswap/basicswap.git
cd basicswap/docker/

It's significantly faster to set COINDATA_PATH in the linux filesystem. You can access it from the windows side at: \\wsl$\Ubuntu

Continue from the Run Using Docker section.

Run Without Docker:

Ubuntu Setup:

apt-get install -y wget git python3-venv python3-pip gnupg unzip automake libtool pkg-config curl jq

OSX Setup:

Install Homebrew (See https://brew.sh/):

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Dependencies:

brew install wget unzip python git protobuf gnupg automake libtool pkg-config curl jq

Close the terminal and open a new one to update the python symlinks.

Basicswap:

export SWAP_DATADIR=/Users/$USER/coinswaps
mkdir -p "$SWAP_DATADIR/venv"
python3 -m venv "$SWAP_DATADIR/venv"
. $SWAP_DATADIR/venv/bin/activate && python -V
cd $SWAP_DATADIR
wget -O coincurve-anonswap.zip https:/tecnovert/coincurve/archive/refs/tags/anonswap_v0.2.zip
unzip -d coincurve-anonswap coincurve-anonswap.zip
mv ./coincurve-anonswap/*/{.,}* ./coincurve-anonswap || true
cd $SWAP_DATADIR/coincurve-anonswap
pip3 install .


cd $SWAP_DATADIR
git clone https:/basicswap/basicswap.git
cd $SWAP_DATADIR/basicswap

If installed on OSX, you may need to install additional root ssl certificates for the ssl module. From https://pypi.org/project/certifi/

sudo python3 bin/install_certifi.py

Continue installing Basicswap

pip3 install .

Prepare the datadir:

CURRENT_XMR_HEIGHT=$(curl https://localmonero.co/blocks/api/get_stats | jq .height)

basicswap-prepare --datadir=$SWAP_DATADIR --withcoins=monero --xmrrestoreheight=$CURRENT_XMR_HEIGHT

OR using a remote/public XMR daemon (not recommended):
XMR_RPC_HOST="node.xmr.to" BASE_XMR_RPC_PORT=18081 basicswap-prepare --datadir=$SWAP_DATADIR --withcoins=monero --xmrrestoreheight=$CURRENT_XMR_HEIGHT

Record the mnemonic from the output of the above command.

Start Basicswap:

basicswap-run --datadir=$SWAP_DATADIR

Open in browser: http://localhost:12700 It may take a few minutes to start as the coin daemons are started before the http interface.

Add a coin (Stop basicswap first):

export SWAP_DATADIR=/Users/$USER/coinswaps
basicswap-prepare --usebtcfastsync --datadir=/$SWAP_DATADIR --addcoin=bitcoin

Start after installed:

export SWAP_DATADIR=/Users/$USER/coinswaps
. $SWAP_DATADIR/venv/bin/activate && python -V
basicswap-run --datadir=$SWAP_DATADIR
