Associated token account (ATA)
Last updated:
Applies to: Solana
In more detail
On Solana a wallet does not hold tokens directly: each token balance lives in a separate token account whose owner field is the wallet. The ATA is the conventional one, so senders can compute where to deliver tokens without asking the recipient. Its address depends on the token program, so the same wallet and mint give different ATAs under the classic Token program and Token-2022.
