What Does Freezing a Token Account Do?
Freezing a token account keeps the same owner, mint, and balance, but prevents the token account from transferring or burning tokens until the token account is thawed.
A frozen account can still be closed if the frozen account has a zero token balance.
Only a mint that still has a freeze authority can freeze token accounts. If a mint's freeze authority is revoked, accounts for that mint can no longer be frozen.
How to Freeze a Token Account
Freezing a token account uses the Token Program's FreezeAccount
instruction.
The FreezeAccount 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 initialized to frozen.
Native token accounts do not support freezing.

Typescript
The Kit examples below show the recommended approach using @solana/kit.
Legacy examples using @solana/web3.js are included for reference.
