IdentityDissolved

Event v136 → current #1

Emitted when a user removes their on-chain identity and reclaims their deposit.

Useful for: validatorsanalyticswalletsdevelopers

The Big Picture

Identity dissolution is often a precursor to account changes. Validators might clear identity before retiring or migrating to a new account. This event signals that an account has opted out of public visibility - any systems displaying their identity should update accordingly.

Why This Matters

When a validator clears their identity, it might signal they're retiring or experiencing issues. Delegators should be notified so they can review their stake positions. It's also important for data hygiene - don't display stale identity info for accounts that have cleared it.

Example Scenario

A validator you're staking to clears their identity. IdentityDissolved fires with their account. Your wallet should remove their display name and show just the address. This might be a signal to review your delegation.

Common Questions

Should I be concerned if my validator clears their identity?: Not necessarily - they might be updating to a new identity, or migrating accounts. But it's worth investigating if they don't re-register soon.
Does the account still work after clearing identity?: Yes, the account functions normally. Only the attached metadata is removed. They can still validate, stake, and do everything else - just without public identity info.

Use Cases

Track when validators or accounts remove their identities
Update validator directories when identities are cleared
Monitor for accounts preparing for migration or retirement
Build analytics on identity lifecycle and retention
