EVM error: Contract paused, frozen or blacklisted
The token or protocol is deliberately blocking transfers right now. No fee change or retry will help — the restriction is set by the contract owner.
Why it happens
- The issuer paused the contract (common for stablecoins and regulated tokens).
- Your address was blacklisted by the issuer.
- The protocol is in an emergency shutdown or migration.
- A vesting or lock-up rule blocks transfers until a date.
How to fix it
- Read the contract's pause/blacklist state on the explorer under 'Read contract'.
- Contact the issuer — only they can lift it.
- If the restriction is protocol-wide, wait for the unpause announcement.
- Never send more funds to an address that is already flagged.
