Evidence

Notes and record state

Record note
Launch date is normalized to 2025-06-01 because contemporary shutdown reporting establishes June 2025 but not an exact launch day. The dead classification records the official end of the operated protocol frontend and normal service; immutable smart contracts may remain accessible for direct withdrawals. death_reason is voluntary_shutdown because the team announced a staged wind-down without reporting a hack or insolvency as the cause.
Revision state
Records may be incomplete, approximate, contested, or revised as better evidence becomes available.
