ATTENTION: This wrapper was merged into https://github.com/oxarbitrage/bitshares-explorer-api Development will continue there.

The bitshares udf wrapper

UDF protocol is needed to build DEX market charts with TradingView.

This wrapper will expose an udf API set by calling a bitshares witness node with market_history plugin enabled to get data from the dex.

Install dependencies

Currently the UDF wrapper needs a postgres database with assets. This is done by having https://github.com/oxarbitrage/bitshares-python-api-backend installed. All dependencies needed for this project are covered by having bitshares-python-api-backend. It is expected this to change in the future and being a totally standalone project.

Basic run:

git clone https://github.com/oxarbitrage/udf-bitshares-wrapper.git
export FLASK_APP=wrapper.py
flask run --host=0.0.0.0 --port=5001

Or by having nginx:

#vi /etc/nginx/sites-available/udf
server {
    listen 5001;
    server_name 185.208.208.184;
    location / {
        include uwsgi_params;
        uwsgi_pass unix:/tmp/udf.sock;
    }
}
#ln -s /etc/nginx/sites-available/udf /etc/nginx/sites-enabled/udf
#/etc/init.d/nginx restart

And then in the root of the project start with:

uwsgi --ini wrapper.ini

The following calls are exposed and needed for TradingView to display bitshares dex charts:

• /config - http://185.208.208.184:5001/config
