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

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

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.

cargo run -p scripts --bin create_users

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

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

cargo run -p scripts --bin execute_exchange_scenario

If facing - add hickory-proto = { version = "=0.25.0-alpha.2" } to failing package.
