Optimism-Python: Unofficial Python Client for the OP-Stack
:construction: DISCLAIMER: Reference SDK is still under active development so the repository might be temporarily out of date.
This library is a Python implementation of the OP-Stack SDK. It tries to mirror some of the core functionalities such as:
providing easy access to the OP-Stack contracts
bridging of assets from L1 to L2 (deposits) and vice-versa (withdrawls)
creating withdrawl proofs
Getting started
Installation
pip install optimism-python
Deposit ETH to L2
from web3 import Web3
from optimism import CrossChainMessenger
# Create a node provider for each chain
provider_l1 = Web3(Web3.HTTPProvider("https://eth-mainnet.g.alchemy.com/v2/<your-alchemy-key>"))
provider_l2 = Web3(Web3.HTTPProvider("https://optimism-mainnet.g.alchemy.com/v2/<your-alchemy-key>"))
# Specify an account for each chain (can be the same)
account_l1 = provider_l1.eth.account.from_key("<your-private-key>")
account_l2 = provider_l2.eth.account.from_key("<your-private-key>")
# Create a messenger instance
messenger = CrossChainMessenger(chain_id_l1=1, # Ethereum Mainnet
chain_id_l2=10, # Optimism Mainnet
account_l1=account_l1,
account_l2=account_l2,
provider_l1=provider_l1,
provider_l2=provider_l2)
