Tari Exchange

Proof of Concept project on implementing modern DEX on modern Tari Protocol.

Getting started

Environment configuration

Tari Swarm

To set up the Tari Swarm, you will need to run it from the official repos.

• Tari
• The Ootle

First, copy tari and tari-dan projects to a new folder on your $HOME and checkout feature-dan2 branch for Tari.

cd ~/
mkdir tari_swarm
cd tari_swarm
git clone https://github.com/tari-project/tari.git
git clone https://github.com/tari-project/tari-dan.git
cd tari && git checkout feature-dan2 && cd ../

Next, change the directory to the Tari Dan folder. You will need to create a config file for the Tari Swarm, so run:

cd tari-dan
cargo run --bin tari_swarm_daemon --release -- -c data/swarm/config.toml init

This will create the necessary config.toml file. You should update the number of validator nodes to at least 2.

[[instances]]
name = "Validator node"
instance_type = "TariValidatorNode"
num_instances = 2

Now you will need to run Tari Swarm:

cargo run --bin tari_swarm_daemon --release -- -c data/swarm/config.toml start

In a couple of minutes you should be able to browse to the Tari Swarm by visiting: http://localhost:8080

Component template

We already have [Component Templates] in our repo inside component_templates folder. We generated them using Cargo Generate:

cargo generate https://github.com/tari-project/wasm-template.git wasm_templates/fungible

Now we will compile TEX Component Template into WASM module and deploy to our Validator Nodes.

cargo build-wasm -p tex --release
ls target/wasm32-unknown-unknown/release/

You should see tex.wasm inside target/wasm32-unknown-unknown/release/ now.

Open Tari Swarm UI and scroll down until you see Templates section. Click Choose file, select target/wasm32-unknown-unknown/release/tex.wasm, click upload template.

Open Tari Validator Node UI and check that a new Template with Tex name exists there.

Accounts

cargo run -p scripts --bin create_users

Component instance

Let's instantiate a Component Instance by calling new method on a template.

Copy template address (for example 3b5490a65751641b2c3401c6e8fd1cedbe719198c3116bac6f09972fee1075d6) from UI and paste in developemnt_tools/scripts/src/bin/crate_component_instances.rs.

cargo run -p scripts --bin create_component_instances

Testing

Script

Let's test our exchange by calling it's methods.

cargo run -p scripts --bin execute_exchange_scenario
