The Big Picture

After safe-mode ends and ReleaseDelay passes, depositors can reclaim their funds. The delay gives governance time to assess whether activations were legitimate.

Use Cases

  • Reclaim deposit after safe-mode concludes
  • Recover funds from legitimate activation

From Chain Metadata

Permissionlessly release a deposit for an account that entered safe-mode at a given historical block. The call can be completely disabled by setting [`Config::ReleaseDelay`] to `None`. This cannot be called while safe-mode is entered and not until [`Config::ReleaseDelay`] blocks have passed since safe-mode was entered. Emits a [`Event::DepositReleased`] event on success. Errors with [`Error::Entered`] if the safe-mode is entered. Errors with [`Error::CannotReleaseYet`] if [`Config::ReleaseDelay`] block have not passed since safe-mode was entered. Errors with [`Error::NoDeposit`] if the payee has no reserved currency at the block specified.
