ape-alchemy: Alchemy provider plugins
Project description
Quick Start
Use the Alchemy provider plugin to interact with blockchains via APIs.
The ape-alchemy plugin supports the following ecosystems:
- Ethereum
- Arbitrum
- Base
- Optimism
- Polygon
- Polygon-ZkEVM
Dependencies
- python3 version 3.9 up to 3.12.
Installation
via pip
You can install the latest release via pip:
pip install ape-alchemy
via setuptools
You can clone the repository and use setuptools for the most up-to-date version:
git clone https://github.com/ApeWorX/ape-alchemy.git
cd ape-alchemy
python3 setup.py install
Quick Usage
First, make sure you have one of the following environment variables set (it doesn't matter which one):
WEB3_ALCHEMY_PROJECT_IDWEB3_ALCHEMY_API_KEYWEB3_<ecosystem>_<network>_ALCHEMY_PROJECT_IDWEB3_<ecosystem>_<network>_ALCHEMY_PROJECT_ID
For example, to use both Arbitrum and Ethereum in the same session, you could set both WEB3_ARBITRUM_MAINNET_ALCHEMY_PROJECT_ID and WEB3_ETHEREUM_MAINNET_ALCHEMY_PROJECT_ID.
NOTE: If using non-Ethereum networks, take care to install the correct plugins, such as ape-arbitrum, ape-optimism, etc:
ape plugins install arbitrum
Then, either in your current terminal session or in your root RC file (e.g. .bashrc), add the following:
export WEB3_ALCHEMY_PROJECT_ID=MY_API_TOKEN=<value-of-secret-key>
To use the Alchemy provider plugin in most commands, set it via the --network option:
ape console --network ethereum:sepolia:alchemy
To connect to Alchemy from a Python script, use the networks top-level manager:
from ape import networks
with networks.parse_network_choice("ethereum:mainnet:alchemy") as provider:
...
Transaction Traces
If you are using a paid tier of Alchemy, you have access to both Geth and Parity style traces.
Parity traces are faster and thus are the ones uses in Ethereum receipts' show_trace() method:
from ape import networks
alchemy = networks.provider # Assuming connected to Alchemy
txn_hash = "0x053cba5c12172654d894f66d5670bab6215517a94189a9ffc09bc40a589ec04d"
receipt = alchemy.get_transaction(txn_hash)
receipt.show_trace() # Prints the Transaction trace
To access the raw CallTree, do:
from ape import networks
alchemy = networks.provider # Assuming connected to Alchemy
txn_hash = "0x053cba5c12172654d894f66d5670bab6215517a94189a9ffc09bc40a589ec04d"
call_tree = alchemy.get_call_tree(txn_hash)
