Bridge Facet

The Bridge feature allows users to bypass the full cooldown period when withdrawing their money. Certain addresses can be designated as "bridges" within the system. The method transferToBridge enables users to quickly transfer the amount they wish to withdraw. The trusted bridge will then send that amount to the user's wallet outside of SYMMIO. After the cooldown period is complete, the bridge can withdraw that amount from SYMMIO. The bridge is responsible for ensuring user compliance with system regulations. If SYMMIO detects any wrongdoing by the user, the bridge transaction will be suspended, and the bridge may become unable to fully withdraw the funds after SYMMIO restores the transaction.
