- used to hold tokens of specific token mint
- rents can be refunded
- freezeAuthority - an account authorized to freeze the tokens in a token account. If freezing is not a desired attribute, the parameter can be set to null
there’s a big issue with this we can create multiple accounts ( pub keys ) for the same token mint which is bad because which one are you supposed to use?
to make it more deterministic, we use an associated token account which is a PDA which will derive an account from owner and mint
delegating
- you can approve another solana account to transfer / burn tokens from your token account
- authority still remains with the original owner
- max amount of tokens a delegate may transfer / burn is specified during the approval itself
- there can only be 1 delegate account associated with a token account at any given time
- you can revoke it later, after which they cant sign txns to transfer tokens from the owner
- if there’s remaining amount from previously approved amount, even that cant be signed for by the delegate
