Polymarket Adds 48-Hour Wait for New Withdrawal Addresses

Polymarket has introduced a withdrawal address allowlist that requires email verification and a 48-hour wait for new destinations, giving users a way to limit unauthorized transfers.

Once users enable the setting, withdrawals can go only to addresses they have approved. A newly added address cannot receive funds until the verification and waiting period are complete. Users can cancel an address addition by email if they did not request it.

The control is intended to prevent funds from being sent to a new address after a session is hijacked or a malicious transaction is signed. Accounts using an older wallet type can use an available migration tool to switch to the newer type, or create a new account to use the feature.

Separately, Polymarket disclosed a breach at a provider serving its international platform on Oct. 29. Polymarket said the breach had been fixed and promised to reimburse affected traders. Its separate U.S. platform was not affected.

Polymarket also plans to add passkey support.
