coinos-server

Coinos is a bitcoin wallet app that supports payments over the bitcoin, liquid and lightning networks. Try it out at coinos.io.

This repository contains the code for the backend API server which is implemented as a NodeJS application. The code for the frontend UI is tracked separately here.

Install

The follow commands will set up bitcoin, liquid and lightning nodes in regtest mode, along with a coinos app server, database, and front end UI. You'll need to have docker installed as a pre-requisite.

git clone https://github.com/coinos/coinos-server
cd coinos-server
cp -rf sampleconfig ./config
sudo chown $(id -u):$(id -g) config/liquid
sudo chown $(id -u):$(id -g) config/bitcoin
cp .env.sample .env
cp fx.sample fx
docker network create net --gateway 172.18.0.1 --subnet 172.18.0.0/16
docker run -it -v $(pwd):/app --entrypoint pnpm asoltys/coinos-server i
docker-compose up -d
docker exec -i mariadb mysql -u root -ppassword < db/schema.sql   
docker exec -it bitcoin bitcoin-cli createwallet coinos
docker exec -it bitcoin bitcoin-cli rescanblockchain
docker exec -it bitcoin bitcoin-cli generatetoaddress 500 $(docker exec -it bitcoin bitcoin-cli getnewaddress "" "p2sh-segwit")
docker exec -it liquid elements-cli createwallet coinos
docker exec -it liquid elements-cli rescanblockchain
docker exec -it liquid elements-cli sendtoaddress AzpsKhC6xE9FEK4aWAzMnbvueMLiSa5ym1xpuYogFkHzWgMHSt8B79aNNbFppQzCSQ2yZ9E4nL6RQJU7 1000000
docker exec -it liquid elements-cli generatetoaddress 1 AzpsKhC6xE9FEK4aWAzMnbvueMLiSa5ym1xpuYogFkHzWgMHSt8B79aNNbFppQzCSQ2yZ9E4nL6RQJU7
docker exec -it lnd lncli create # set password to "password"
sed -i "s/# wallet/wallet/g" config/lnd/lnd.conf
CERT=$(sudo base64 config/lnd/tls.cert | tr -d '\n') 
sed -i "s/LS0tL.*\"/$CERT\"/g" config/index.js
MACAROON=$(sudo base64 config/lnd/data/chain/bitcoin/regtest/admin.macaroon | tr -d '\n') 
sed -i "s/AgED.*\"/$MACAROON\"/g" config/index.js

After successful creation of all docker containers coinos ui will be available at http://localhost:8085 and coinos server will be available at http://localhost:3119

docker exec -it cl lightning-cli getinfo
docker exec -it lnd lncli --network=regtest --chain=bitcoin connect 029ba19ec5f65f82b1952fd535a86ff136ccc67ff7f91e19c3fcbc83a5224adaee@cl:9735
