You may need MATIC tokens for gas.

Unlike Hive, Polygon does use gas fees, but they are cheap.

Visit https://tribaldex.com/trade/SWAP.MATIC and use KeyChain,
to deposit Hive and acquire SWAP.MATIC.

Then you can withdraw your MATIC to your wallet address.

Then you will have gas to pay for the tx, to claim your airdrop.
