Hello i'm trying to understand how flashbots Bundles are working. So far i can send a flashbots Bundle with several transactions that i made. But in the official docs it is stated that we can include a transaction from the mempool this way:
signedTransaction: SIGNED_ORACLE_UPDATE_FROM_PENDING_POOL // serialized signed transaction hex
What is exactly this SIGNED_ORACLE_UPDATE_FROM_PENDING_POOL?
I tried in every way possible to serialize a signed transaction but i cannot make it work. Obviously the serializeTransaction from ethers.js cannot serialize a signed tx and even with ethereumjs/tx i cannot get this value.
I am sorry if there is something obvious here that i didn't understand but i've been trying to understand this for 2 days full time now, i could really use a little help :)
Thanks so much for your help!
