Web3.py – What Version of Web3.py Does ApeWorX Support and Does It Support Account Impersonation Without Private Key?

browniepythonweb3.py

What is the most recent web3py version that ApeWorX supports? I need to have support for unlocking random eth accounts on a local test network (ex: http localhost 8545) through something like hardhat (npx hardhat node) using a hardhat fork (infura, alchemy, quicknode, etc), WITHOUT actually having the private key of the account simply for testing purposes like you can with brownie when defining the unlock parameter in brownie-config.yaml? Is it possible to fork and unlock accounts without the private key in ApeWorX? This is to impersonate a given eth account without needing to posses the private key of the account. Any Information would be most helpful!

Ape supports v6 of Web3py, so whatever the latest release is would be recommended (6.3.0)

Ape supports impersonation if the provider you're using does (foundry or hardhat do)

You can pass an address string or contract instance value as sender= in a transaction to send from an account (e.g. c.upgrade(sender=c.govnernance())) or you can load an impersonated account in a test via a = accounts[address]

The RPC methods under personal_* are not exposed by default. The question set it up correctly. (although today, the correct arg is --jsonrpc-apis 'eth,web3,personal').

If you are still failing to connect, and you are using IPC, note that the argument above only sets up calls over HTTP. If you are using IPC, you need to use --ipc-apis 'eth,web3,personal' instead.

If you would rather not expose the personal APIs, for security reasons, you can use the eth_accounts RPC call.

>>> web3.eth.accounts
['0x...']

Web3 Py Public Private Key – How to Get Public Key from Private Key Using Web3py

If you want convert private key to public key and not address, then I would recommend using eth-keys library. It is in the dependencies of eth-account library, which is in the dependencies of web3py.

Private key, used for account generation, consists of 64 hexadecimal characters (32 bytes total). So, if you have 32-bytes private key, then public key can be acquired with the following code:

>>> from eth_keys import keys
>>> pk = keys.PrivateKey(your_32bytes_private_key)
>>> print(pk.public_key)

If your private key is a string of 64 characters, then it can be converted to 32-bytes private key with the following code:

>>> import codecs
>>> decoder = codecs.getdecoder("hex_codec")
>>> private_key_bytes = decoder(private_key_str)
