SECTION 3 (Workshop)

[Scofield-Idehen]

If you get stuck in this workshop, here is a workaround on how I did mine, first I set up a new directory and initialize it using uv init

You might encounter a bit of a dependencies issue here, I did have to change which Venv I was, make sure to figure this out and install Titanoboa using uv add

create a new file, I set mine as dad.vy Here you have to think about the assignment properly

Here is my code structure.

# pragma version 0.4.0
# @license MIT

fav_scofield: uint256
my_bool: bool  # Changed from String to bool

@deploy 
def __init__():
    self.fav_scofield = 24
    self.my_bool = False  # Initialize with default value

@external 
def new_store(_value: uint256):
    self.fav_scofield = _value

@external
def set_bool(_new_value: bool):
    #set bool to whatever is passed but what if bool is set to something othern than true or false
    #how do i catch this error?
    self.my_bool = _new_value

@external
@view
def get_bool() -> bool:
    return self.my_bool

    

Next, I created my deploy.py script and here I took a lot from the previous class as it was the same thing I only changed the file name and the functions in your .vy

You can find mine here here

once confirmed make sure you run python [NAME_OF_FILE]

Copy the contract address and then create an interact.py file set the MY_CONTRACT address to the contract gotten from the deploy script you ran above

Here is how mine looked after I was done

import boa
from dotenv import load_dotenv
from boa.network import NetworkEnv, EthereumRPC
from eth_account import Account
import os

load_dotenv()

MY_CONTRACT = "0x5FbDB2315678afecb367f032d93F642f64180aa3"

def main():
    rpc = os.getenv("RPC_URL") 
    env = NetworkEnv(rpc=EthereumRPC(rpc))
    boa.set_env(env)


    anvil_key = os.getenv("ANVL_KEY")
    myaccount = Account.from_key(anvil_key)
    boa.env.add_account(myaccount, force_eoa=True)


    fav_partial = boa.load("dad.vy")

    fav_partial.set_bool(True)
    

    fac = fav_partial.get_bool()
    print(f"current bool value {fac}")
    

Tenderly

If you want to deploy on Tenderly, change the RPC from Anvil to the Tenderly network RPC and copy your private key from Metamask.

Review the previous videos on Tenderly to understand how Patrick connects Tenderly with Metamask.

Copy the new contract after deploying the contract into the MY_CONTRACT and interact with the deployed contract.

Workshop done.
