Event v154 → current #4

Emitted when a reserved deposit is returned to its owner.

Useful for: validatorsdevelopersanalytics

The Big Picture

A depositor got their funds back. This typically happens after safe-mode ends and the ReleaseDelay passes, confirming the activation was not abused. Governance can also force-release deposits early in special circumstances.

Use Cases

Confirm deposit recovery after safe-mode incidents
Track deposit lifecycle for governance
Monitor legitimate vs force-released deposits
