How can ADA gas be simply funded?

[Arnie]

The ADA in my old MetaMask wallet needs to be migrated, and it needs $0.02 in ADA gas, but the funds aren't showing up. Since my crypto is on the ETH and Solana chains, how do I get this little ADA sum into my wallet the simplest?

MetaMask doesn't support ADA directly, your ADA is stored in a multichain wallet, which uses a different address format than your MetaMask.

To fund ADA gas for your wallet, transfer a small amount of ADA through a US-regulated exchange like Coinbase or Kraken to your Cardano wallet. On the exchange, trade ETH/SOL for ADA and send that ADA to your actual Cardano wallet.
