# Curve Chaser Vault Scripts

The Volume Finance team has developed Python scripts to trigger the logic in the Chaser Vault smart contract. These scripts are available in the same source code repository (opens new window).

# deposit.py

The deposit script (opens new window) loads in a user's account and uses an ABI to pass arguments to the vault contract where a deposit is triggered from the user's account into the Chaser vault.

def main():
    acct = accounts.load("deployer_account")
    Vault = Contract.from_abi("Curve APY Chaser Vault", "0xE9F20140Eb23A9d0AD2B2353F2FBE370203F3082", <PARAMETERS>)
    DAI = Contract.from_abi("DAI", "0x6B175474E89094C44Da98b954EedeAC495271d0F", <PARAMETERS>)
    DAI.approve(Vault, 1000 * 10 ** 18, {"from": acct})
    Vault.deposit(DAI, 1000 * 10 ** 18, 1, [], 1, {"from": acct})

# withdraw.py

The withdrawl script (opens new window) loads in a user's account and uses an ABI to pass arguments to the vault contract where withdrawal is triggered from the Chaser vault back to the user's account.

def main():
    acct = accounts.load("deployer_account")
    Vault = Contract.from_abi("Curve APY Chaser Vault", "0xE9F20140Eb23A9d0AD2B2353F2FBE370203F3082", <PARAMETERS>)
    DAI = Contract.from_abi("DAI", "0x6B175474E89094C44Da98b954EedeAC495271d0F", <PARAMETERS>)
    bal = Vault.balanceOf(acct)
    Vault.withdraw(DAI, bal, 1, [], 1, {"from": acct})

# deploy.py

The deployer script (opens new window) passes arguments to deploy the vault smart contract.

def main():
    acct = accounts.load("deployer_account")
    curve_apy_vault.deploy("Curve APY Vault", "CAV", "0x5a6A4D54456819380173272A5E8E9B9904BdF41B", "0xA79828DF1850E8a3A3064576f380D90aECDD3359", 4, "0x5a6A4D54456819380173272A5E8E9B9904BdF41B", False, {"from": acct})

# updatepool.py

The pool updater script (opens new window) loads in a user's account, recognizes the current Curve pool in the vault, and passes the associated arguments into the vault smart contract once a better Curve pool is found to trigger the update_pool event to swap the current pool.

def main():
    acct = accounts.load("deployer_account")
    Vault = Contract.from_abi("Curve APY Chaser Vault", "0xE9F20140Eb23A9d0AD2B2353F2FBE370203F3082", <PARAMETERS>)
    withdraw_token = ""
    token_index = 0
    swap_route = []
    main_pool = ""
    main_deposit = ""
    deposit_token_index = 0
    main_coin_count = 0
    lp_token = ""
    is_crypto = False
    Vault.update_pool(withdraw_token, token_index, swap_route, main_pool, main_deposit, deposit_token_index, main_coin_count, lp_token, is_crypto, 1, {"from": acct})
