# update\_whitelist

An entrypoint that updates a list of whitelisted tokens. Tokens can be added to whitelist or can be removed from it.

Whitelisted tokens can be [withdrawn](https://docs.quipuswap.com/smart-contracts/dex-2.0/auction-contract/entrypoints-overview/admin-entrypoints/withdraw_public_fee) by an administrator of the contract. Any user can [launch](https://docs.quipuswap.com/smart-contracts/dex-2.0/auction-contract/entrypoints-overview/auction-entrypoints/launch_auction) an auction for **NON** whitelisted tokens.
