Web client: https://codeberg.org/silverpill/mitra-web

Ethereum contracts: https://codeberg.org/silverpill/mitra-contracts

Requirements

• Rust 1.56+ (when building from source)
• PostgreSQL 12+

Installation

Building from source

Run:

cargo build --release --features production

This command will produce two binaries in target/release directory, mitra and mitractl.

Install PostgreSQL and create the database:

CREATE USER mitra WITH PASSWORD 'mitra';
CREATE DATABASE mitra OWNER mitra;

Create configuration file by copying contrib/mitra_config.yaml and configure the instance. Default config file path is /etc/mitra/config.yaml, but it can be changed using CONFIG_PATH environment variable.

Put any static files into the directory specified in configuration file. Building instructions for mitra-web frontend can be found at https://codeberg.org/silverpill/mitra-web#project-setup.

Start Mitra:

./mitra

An HTTP server will be needed to handle HTTPS requests. See the example of nginx configuration file.

To run Mitra as a systemd service, check out the systemd unit file example.

Debian package

Download and install Mitra package:

dpkg -i mitra.deb

Install PostgreSQL and create the database:

CREATE USER mitra WITH PASSWORD 'mitra';
CREATE DATABASE mitra OWNER mitra;

Open configuration file /etc/mitra/config.yaml and configure the instance.

Start Mitra:

systemctl start mitra

An HTTP server will be needed to handle HTTPS requests. See the example of nginx configuration file.

Monero

Install Monero node or choose a public one.

Configure and start monero-wallet-rpc daemon. Add disable-rpc-login=1 to your monero-wallet-rpc config (currently RPC auth is not supported in Mitra).

Create a wallet for your instance.

Add blockchain configuration to blockchains array in your configuration file.

Ethereum

Install Ethereum client or choose a JSON-RPC API provider.

Deploy contracts on the blockchain. Instructions can be found at https://codeberg.org/silverpill/mitra-contracts.

Add blockchain configuration to blockchains array in your configuration file.

Development

See CONTRIBUTING.md

Start database server

docker-compose up -d

Test connection:

psql -h localhost -p 55432 -U mitra mitra

Start Monero node and wallet server

(this step is optional)

docker-compose --profile monero up -d

Run web service

Create config file, adjust settings if needed:

cp config.yaml.example config.yaml
