Lesson 10: Defi & Aave (contract object)

[SJ50]

in get_weth function, we use weth = interface.IWeth(config["networks"][network.show_active()]["weth_token"])
what would be the drawback for using weth = Contract.from_explorer(config["networks"][network.show_active()]["weth_token"]) ?

when I use Contract.from_explorer, I get following warning is that a concern and how can eliminate it?

If I want to use weth = Contract.from_abi(name, weth_ecr20_address, abi), what would be best method to load abi.json?

I am using following for Contract.from_abi
in helpful_scripts.py

import json
def get_abi(path):
    with open(path) as abi_file:
        abi = json.load(abi_file)
        return abi

in get_weth.py

abi = get_abi("./interfaces/weth_abi.json")
weth = Contract.from_abi("weth", weth_ecr20_address, abi)

Hello @SJ50 what a good question, well I would say that is just the remote compiler version is not compatible with the brownie accepted compilers, however this question got me out of the blue @PatrickAlphaC any thoughts on this?

I have forgot to mention; despite that warning, transactions goes through.
