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)
