Set up a wallet.
Use MetaMask, Rabby, or Trust Wallet and switch to BNB Smart Chain.

Get BNB.
Buy BNB on a major exchange and withdraw it to your wallet on BNB Smart Chain. BNB is all you need: TopazDEX automatically routes your swap to the AIRO/USDT pool, and the same BNB covers your gas fees. Swapping from USDT works too.

Open TopazDEX.
Open TopazDEX or check the trading pair on DexScreener.

Swap BNB for $AIRON.
Select BNB as input, paste the contract as output token, and swap. Start with a small amount to test. Always verify that the contract address matches this website.
