Can MAM publish messages of 1i that aren't deleted by snapshots?

  • How about a bit more context?

There is no value transfer within MAM.

It's a messaging api


  1. MAM does not support value transfer
  2. All transactions (also the ones that send 1i) are deleted by a snapshot (on non-permanodes), only the final balances remain.

Therefore if you need transactions to survive across snapshots, you'd better find (or run) a permanode. (The only permanode I know of is run by the admin of thetangle.org for his tangle explorer. But I think there is interest for more.)
