Stable's airdrop is finally available for claiming. However, it seems Merkl is currently down, so we have to wait for it to be restored.

Here’s the claiming process:

First, send USDT from an EVM chain to Stable. Bridging from Arbitrum to Stable is the most common way. Next, convert the USDT on Stable to gUSDT. This will be used for gas fees. Once you’re ready, just claim from the claiming screen.

Depending on Merkl’s server status, it might be best to try once things have settled down.
