Polymarket launches withdrawal address whitelist: adding a new address requires email verification and a 48-hour lock

November 10: Josh Stevens, Vice President of Engineering at Polymarket, announced that the platform has launched a withdrawal address whitelist feature. Users can lock the withdrawal address of their deposit wallet; adding a new address requires email verification and a 48-hour time lock, and any action not initiated by the user can be canceled via email. This means that even if a session is compromised or a malicious transaction is mistakenly signed, funds cannot be transferred to an address outside the user's control. The feature can be enabled in "Settings - Account," with Passkey support coming soon. In addition, the team is developing a migration tool for non-deposit wallets and will roll out advanced built-in security protection that does not require manual activation.
