Thaw Account

What Does Thawing a Token Account Do?

Thawing changes a token account from the frozen state back to the initialized state.

After a thaw succeeds, the account can transfer, burn, and close tokens again. Only the mint's freeze authority can thaw token accounts.

How to Thaw a Token Account

Thawing a token account uses the Token Program's ThawAccount instruction.

The ThawAccount instruction verifies that the token account belongs to the mint and that the signer is the mint's freeze authority, then changes the token account state from frozen back to initialized.

Native token accounts do not support thawing.
