Emitted when reserved balance is moved from one account to another.

Useful for: developersanalytics

The Big Picture

Reserve repatriation moves reserved funds from one account to another without going through the free balance. This is used in scenarios like slashing (moving reserved collateral to a beneficiary) or deposit transfers. The destination_status determines whether the funds become free or reserved in the receiving account.

Use Cases

Track reserve transfers between accounts
Monitor slashing or deposit reallocation
Build reserve balance tracking tools

From Chain Metadata

Some balance was moved from the reserve of the first account to the second account. Final argument indicates the destination balance type.

Triggers

Preconditions

Source account has sufficient reserved balance
Repatriation operation authorized

Effects

Postconditions

Source reserved balance decreased
Destination balance increased (reserved or free based on status)

Side Effects

May affect existential deposit calculations for both accounts
