So far, I only understand flashbot bundles are signed raw transactions with one of them being a bribe to the miner for the mining fee, but :
- Is the bribing transaction special in the way it is valid for all all
block.coinbasebeing used or is it valid only for a single miner? If yes, how do I build and sign such special formated bribing transactions?
- In order to determine the gas price for standard/mempool transactions, there’s https://ethgasstation.info/, but how to compute the minimal amount for the bribe being sent to
block.coinbasewhich would allow getting the bundle mined into a reasonable timeframe? I’m asking this in general and without considering competition because I imagine miners won’t accept transaction which doesn’t pay more than gas price and that the price to be paid isn’t flat in the way the amount of gas consumed still matters.
- Since I’m not running my own node, how I can build such transaction bundles from my signed rawtransaction list, and how to submit them to the flashbots relay without running my own node once they are built into the correct binary format? Something which is not explained by https://github.com/flashbots/pm/blob/main/guides/searcher-onboarding.md
- If I create my own mining pool, how can I receive flashbot transaction? Is there a place where I need to subscribe?
My interest, here isn’t to create transaction bundles since there’s a single transaction to perform in the case I’m interested in, but to get that transaction being mined first since flashbot transactions are mined at the beginning of the block (frontrunning transactions still using the mempool). And with the point that nobody is using flashbots yet.
Though I understand that I need to create a bundle of at least 2 transactions though since one of them must be for the miner.
