Transaction Replay on BDashJr

[calkob]

I sent a transaction in the last couple days and it was replayed on BDashjr how does this only happen to certain transactions?

Is it one of my peers, like a Knots peer?

A pair could be involved but I don’t think the pair itself is what determines whether the transaction can be replayed.
Replayability essentially depends on whether the transaction is valid on both chains and also if the UTXOs it spends exists on both chains.
Another node can relay the same transaction and the other chain may accept it too if the transaction and its inputs are compatible on both set of consensus rules.

More details on the transaction could highlight why this is happening. The inputs and outputs could give better indication of why this particular transaction was replayable while the rest were not.

You have to sweep your coins on the BDashJr chain first to stop the replays. Tutorial

The key is to sign your inputs with SIGHASH_UNIFIED, which is not supported in BTC.
