Zaun

This repository contains interfaces and functions to interact with starknet solidity contracts.

One can use two options for deploying the implementation contract :

• deploy_contract_behind_unsafe_proxy : This will deploy the contract behind a minimal proxy and can be used for dev purposes.

• deploy_contract_behind_safe_proxy : This will deploy the contract behind a safe audited proxy and setting the implementation and upgrades

Setup

curl -L https://foundry.paradigm.xyz | bash
foundryup

Testing

Unit

forge test -vv

Devnet

Start Anvil as background process w/ Core Contracts and STARK token:

./script/sn-base-dev.sh

Kill Anvil deployment:

./script/sn-base-kill.sh

Artifacts

Zaun sandbox crate can be used as dev dependency in external projects. If any changes made to the Solidity contracts, one has to re-generate Ethers bindings (this won't be done automatically).

make artifacts
