I might love to do RBF testing on testnet. I might wish to simulate a transaction with too-low charges, aka "caught" transaction, after which RBF it in varied methods.
Drawback is, all testnet transactions are added to the subsequent block resulting from mostly-empty mempool and 1 sat/B charge charge.
Is there a intelligent approach to create a transaction that sits within the testnet mempool, which might be later mined after RBF?
