# List wallets eligible for Babylon airdrop

> This operation lists all wallets that are eligible for the Babylon airdrop. If an eligible wallet's status is `Unregistered`, you can initiate an airdrop registration for it. You can filter the results by airdrop registration status.

You can use this operation to:
- Check which wallets are eligible for airdrop registrations
- Estimate airdrop amounts before claiming
- Monitor available airdrop

As registration is an asynchronous process and might take some time to complete, it is recommended that you regularly call this operation to check wallet eligibility and register eligible wallets on time.

For more information, refer to [Babylon's official doc](https://github.com/babylonlabs-io/babylon/tree/main/docs).
