Sending bundled transactions in one block

Hi! My name is Andrew.

I am a software developer and am learning about web3 and Blockchain, specifically for Ethereum based chains.

I have a specific issue that I am hoping someone here can help me with…

  1. I use PulseChain, an Ethereum fork started in May 2023, Chain Id 369.
  2. Due to my own stupidity/carelessness, I believe (though I’m not entirely sure) that one of my wallets was compromised (seed phrase exposed).
  3. The wallet is now empty except that it was used to initiate a stake…
  4. The stake ends in a few months, so I am concerned that a monitoring bot will automatically transfer my coins…
  5. Someone suggested that with Flashbots I can create a JavaSript that will bundle multiple transactions (ie. unlock stake and transfer coins to a safe wallet) so that they are included into a single block and thus preventing them being stolen…

Is the above correct?
I saw something about a flashbots RPC…will that support PulseChain?

Can someone in the community assist me?

Unfortunatelly, there is no falshbots service in pulsechain, might just monitor the block your stake will unlock, and set high priority fee to front run hackers
