The replacement address came first
SlowMist certified the BNB contract on 24 August 2023. XT nevertheless opened MEMETOON trading a month later against the Polygon address. In October, LBank took a snapshot and XT announced that, at the project’s request, one old token would be exchanged for one token at the BNB address.
This was a balance operation performed by exchanges. Neither contract contains the bridge, and no reviewed source publishes an old-token burn or a claim route for wallets outside participating custodians. Both contracts still return 100 billion nominal units, so their figures describe two legs of one replacement rather than 200 billion units to aggregate.
