Setup

• Install Rust
• Install Solana (stable version, not latest)
• Install Docker
• Install nextest
• Install llvm-cov

Repository

This repository contains 7 crates:

• autara-lib: Main library of the Autara protocol, defining the data structures and logic
• autara-client: A client to interact with the Autara protocol
• autara-program-lib: Library for Arch smart contracts
• autara-program: Autara smart contract
• autara-integration-tests: Standalone crate for the Autara smart contracts integration tests
• autara-pyth: A naive client to push Pyth price feeds to autara-oracle smart contracts
• autara-oracle: A naive oracle smart contract to store Pyth price feeds without any validation

Build

To build smart contracts, run the following command:

cargo-build-sbf --features entrypoint

To build workspace, run:

cargo build

Local environment

Setup an arch local environment:

docker pull --platform linux/amd64 baptisteeb/arigato-node:latest
docker run -d --platform linux/amd64 --name arigato-node -p 18443:18443 -p 3030:3030 -p 9002:9002 baptisteeb/arigato-node:latest

Then, deploy the smart contracts:

cargo run --bin deploy

Run Pyth Pusher

cargo run --bin autara-pyth

Run demo

cargo run --bin autara-client

Autara Server

cargo run --bin autara-server

Test

cargo nextest run --no-fail-fast -j 24

If you dont have a local arch node running, you can run the tests with the following command:

cargo nextest run --exclude autara-integration-tests --workspace

Run tests with coverage:

cargo llvm-cov nextest --exclude autara-integration-tests --workspace
