# Important Notes

1. Gas Fee Reminder\
   When sending an airdrop, your account must hold enough gas tokens (EDS, for example) to cover:

* The gas cost for distributing the airdrop
* Optional gas fees on behalf of recipients, enabling gas-free claiming for new users

2. Supported Tokens

* Luffa will continue to expand the list of supported tokens
* To request support for your project’s token, please email: <support@luffa.im>
* Token listing requests must include project documentation, and the token must be deployed on the Endless blockchain

&#x20;3\. Airdrop Expiry Policy

* Each airdrop is valid for 24 hours
* Unclaimed portions will expire after the time limit and can be manually reclaimed by the sender
