Expand description

Summary

Freezes the account at address. The sending account of this transaction must be the Treasury Compliance account. The account being frozen cannot be the Diem Root or Treasury Compliance account. After the successful execution of this transaction no transactions may be sent from the frozen account, and the frozen account may not send or receive coins.

Technical Description

Sets the AccountFreezing::FreezingBit to true and emits a AccountFreezing::FreezeAccountEvent. The transaction sender must be the Treasury Compliance account, but the account at to_freeze_account must not be either 0xA550C18 (the Diem Root address), or 0xB1E55ED (the Treasury Compliance address). Note that this is a per-account property e.g., freezing a Parent VASP will not effect the status any of its child accounts and vice versa.

Events

Successful execution of this transaction will emit a AccountFreezing::FreezeAccountEvent on the freeze_event_handle held in the AccountFreezing::FreezeEventsHolder resource published under 0xA550C18 with the frozen_address being the to_freeze_account.
