On December 19, 2025, MANTRA CEO John Patrick Mullin sent an open letter proposing that MANTRA manually handle the migration of all OM tokens held on OKX between January 3 and 5 to mitigate holiday-related risks. OKX, which said 34,097,848 user OM tokens and 124,441,487 of its own OM tokens require migration, asked MANTRA to confirm by December 20, 2025 that the full amount on its platform will be migrated or risk potential delisting. The exchange friction follows public disputes earlier in December over token migration communications and OKX's handling of the OM crash in April 2025.
