Solana Freeze Authority: How to Read the Number Before a Swap

A Solana freeze authority can freeze token accounts, stopping holders from transferring. Some stablecoins use it for compliance; for new tokens it's a major risk.

Short answer

The freeze authority on a Solana mint can freeze individual token accounts. Regulated stablecoins may keep it for compliance; for a new token, an active freeze authority means your tokens could be frozen and unsellable. Before a swap, read the mint account: null means no freeze authority; an address means someone holds that power. Combine with mint authority and token-extension checks.
