Quick Usage
CLI Usage
First, install a token list, such as the 1inch token list, which contains many tokens that you can use:
ape tokens install tokens.1inch.eth
To see all the tokens you can use, run command:
ape tokens list-tokens
To see other available CLI commands, run:
ape tokens --help
Python Usage
One of the main reasons to use the ape-tokens plugin is to have nicer UX for providing token amounts to contract transactions.
For example, let's say you have a smart-contract named MyContract with a function provideLinkToken() that takes a decimal value of LINK tokens.
The following is an example script that deploys the contract and makes a transaction by expressing the value of LINK as 8.23 LINK:
from ape import accounts, project
my_account = accounts[0]
contract = my_account.deploy(project.MyContract)
contract.provideLinkTokens("8.23 LINK")
Alternatively, if you need the converted value returned to you, you can use the convert tool from the root ape namespace:
from ape import convert
convert("100.1234 BAT", int)
Lastly, to get information about a token, including its contract address, you can do so by importing the tokens member from the root ape_tokens namespace:
from ape_tokens import tokens
bat = tokens["BAT"]
print(bat.address)
