OpenZeppelin Nile Upgrades

Plugin for Nile to deploy and manage upgradeable smart contracts on StarkNet.

⚠️ WARNING! ⚠️

This plugin does not currently validate contracts for upgrade safety (see issue). Review your contracts for upgrade safety before performing any deployments or upgrades.

⚠️ WARNING! ⚠️

This repo contains highly experimental code. Expect rapid iteration. Use at your own risk.

Installation

pip install nile-upgrades

Usage

Run the following functions from scripts with the NileRuntimeEnvironment.

deploy_proxy

Deploy an upgradeable proxy for an implementation contract.

Returns a Nile Transaction instance representing the proxy deployment.

async def deploy_proxy(
    nre,
    account,
    contract_name,
    initializer_args,
    initializer='initializer',
    salt=0,
    unique=True,
    alias=None,
    max_fee_declare_impl=None,
    max_fee_declare_proxy=None,
    max_fee_deploy_proxy=None,
)

• nre - the NileRuntimeEnvironment object.

• account - the Account to use.

• contract_name - the name of the implementation contract.

• initializer_args - array of arguments for the initializer function.

• initializer - initializer function name. Defaults to 'initializer'.

• salt - the salt for proxy address generation. Defaults to 0.

• unique - whether the account address should be taken into account for proxy address generation. Defaults to True.

• alias - Unique identifier for your proxy. Defaults to None.

• max_fee_declare_impl - Maximum fee for declaring the implementation contract. Defaults to None.

• max_fee_declare_proxy - Maximum fee for declaring the proxy contract. Defaults to None.

• max_fee_deploy_proxy - Maximum fee for deploying the proxy contract. Defaults to None.

Example usage:

tx = await nre.deploy_proxy(nre, account, "my_contract_v1", 123, True, ["arg for initializer"])
tx_status, proxy_address, abi = await tx.execute(watch_mode="track")

upgrade_proxy

Upgrade a proxy to a different implementation contract.

Returns a Nile Transaction instance representing the upgrade operation.

async def upgrade_proxy(
    nre,
    account,
    proxy_address_or_alias,
    contract_name,
    max_fee_declare_impl=None,
    max_fee_upgrade_proxy=None,
)

• nre - the NileRuntimeEnvironment object.

• account - the Account to use.

• proxy_address_or_alias - the proxy address or alias.

• contract_name - the name of the implementation contract to upgrade to.

• max_fee_declare_impl - Maximum fee for declaring the new implementation contract. Defaults to None.

• max_fee_upgrade_proxy - Maximum fee for upgrading the proxy to the new implementation. Defaults to None.

Example usage:

tx = await nre.upgrade_proxy(nre, account, proxy_address, "my_contract_v2")
tx_status = await tx.execute(watch_mode="track")
