The Celestia Genesis Airdrop dApp allowed you to connect to MetaMask using either Leap Snap or Mystic Labs Snap.
If you'd used Mystic Labs Snap for the claim, the Celestia wallet address it would've generated is different from the one you'd see today using any of Leap Snaps, Leap Wallet or Keplr, all of which produce the same Celestia address from the same seed phrase.
If you'd used Leap's MetaMask Snap for the claim, the address you'd see today would be consistent with the one earlier.
Here’s a video of a step-by-step guide on how to check which Snap was used on Celestia's Genesis claim page.👇
To confirm which Snap you had previously used, navigate to your MetaMask wallet's Settings, select 'Snaps', and then check the 'Connected sites' section at the bottom of each installed Snap's page.
Alternatively, you can follow these 4 easy steps.👇
Open your MetaMask wallet and click on “enigmatic ellipsis - 3 dots” in the top right corner.
Go to settings and click on Snaps
Now, look for Mystic Snap or Leap Snap in the list.
Click on the respective Snap and check for genesis.celestia.org option in the list.
If you get genesis.celestia.org under Mystic Snap, follow the below process to transfer your TIA funds from Mystic Snaps address to Leap/Keplr Wallet
