Tari Ootle

This is where you can find the cutting-edge development of the Tari smart contract layer.

You can read about the technical specifications of the Ootle in the RFCs.

If you’re looking for the core Tari base layer code, it’s in this repository

Documentation

Prerequisites

You will require the following tools and dependencies to successfully build the Ootle and/or run the Ootle locally via the Localnet environment:

• C/C++ compiler

  • Linux: gcc or clang
  • macOS: clang (via Xcode CLI tools)
  • Windows: MSVC (via Visual Studio Build Tools)

• Build tools

  • make, cmake, or equivalent
  • pkg-config (Linux/macOS)

• Libraries

  • OpenSSL development libraries (libssl-dev)
  • SQLite development libraries (libsqlite3-dev)
  • Protobuf compiler (protoc) and headers (libprotobuf-dev)

• Other

  • git

• Rust (=1.88): Install Rust using rustup, and add a WASM target:

# Install the rust version in rust-toolchain.toml
rustup install
# Add wasm target
rustup target add wasm32-unknown-unknown

Web UIs

Node.js (>=20.x) & npm: Node.js is required for building the validator node, indexer and wallet web UIs. NOTE: this is not required, and the binaries will still run and compile without building the web UIs.

Follow the instructions at node.js for your desired operating system and package/version managers. We recommend installing Node.js via nvm to easily manage versions across projects.

We use pnpm for package management.

Accessing the Ootle Testnet

The Tari Ootle Wallet Daemon is available on the project’s releases page. Unzip the binaries, then run:

tari_ootle_walletd --network igor -b 

This will start a wallet connected to the Igor Testnet. You can view the public Nodes here:

• Validator Node: http://18.217.22.26:12006
• Indexer: http://18.217.22.26:12502

Navigate to http://127.0.0.1:5100 to create an account, claim test tokens and start testing features.

Running a Small Ootle Network Locally (Localnet)

NOTE: This repository is under heavy development. We’ll try to keep instructions up to date, but they may become outdated.

Confirm you have installed all the prerequisites listed in the Prerequisites section (Rust, Node.js, npm, linux dependencies)

The easiest way to test out the Ootle is to use the tari_swarm_daemon. This will spin up all necessary MinoTari and Ootle applications for a localnet network.

Clone both the tari and tari-ootle repositories in the same folder:

mkdir 
cd
