How to Send Discrete Blockchain Transactions and Avoid Front Running With Submarine Sends

In this video, we look at how to use the ideas presented by libsubmarine.org to send submarine send style transactions to avoid the Front Runners on the Ethereum, Binance Smart Chain or Arbitrum (etc) based blockchains.
In the last video, we spoke about front running and we looked at a real life example on a self-hosted Ethereum full node of mempool transactions being listened to.
The idea with a Submarine Send is to send a transaction that looks like any other transfer transaction to a special type of address. I have modified and come up with a variation of this which works for swaps, but can also work for arbitrage etc. The idea here is to have the contract address recalculated based upon some input criteria (including a salt/password that only you know). Once a transaction has been sent carrying ETH to the new address, it can later be called and derived using your password, with neither transaction looking anything like a swap for example.
The Submarine part basically means that our transaction is hidden in a sea of other transactions with no data being sent yet. The data is sent in the Reveal stage of this elaborate Commit and Reveal style scheme.
This is quite a complex topic, but has been broken down into mini steps whereby in this video, we walk through a transaction live on the Goerli testnet together so you can see it working in action real time.
What will you use this sort of transaction for?

Awesome Tutorial !

[@CryptoWizards]

Thanks brother!

[@Liebendan]

Thanks for great content

[@CryptoWizards]

Really enjoyed making this video and doing the research

[@jnicholasgross2808]

help me understand something: as part of a transaction in block 0 I send funds from my wallet to the submarine contract for a token swap (ETH for X); eventually (thru the mechanism you described) that swap occurs by the sub contract with say Uniswap; when is X now visible in my wallet? only at the end of block 0 being completed? or the next block or.. what?

[@TheJakeRobinson]

You're a freahin genius! Bravo Now, if you were a frontrunner could they watch this and figure out a counter to it?

[@CryptoWizards]

That is exactly the right thinking imo Jake. The minute I put out the game, it can be figured out. So making this a tool for CW is not worth while likely. Great to hear from you brother.

How do I get VS Code to run on a virtual machine? I'm using Azure from Microsoft which has super fast Internet, which I want to use for triangular arbitrage

[@CryptoWizards]

One thing you can do is to not use VS Code, but rather use nano (sudo nano my_file_name.ts for example). I myself am looking to switch from VS Code to NEOVIM but am only at the start of that journey. Otherwise, not sure how you would do it.

[@owadefelix6476]

Is using flashbot bundles easier? There's no public mempool

[@CryptoWizards]

Good point. Definitely easier. rpc.ethereum.org might also work I believe.

[@22-Zar]

Thanks for the great content! Also, can this Udemy course be up like yesterday 🤣

[@CryptoWizards]

Thanks Lazar! If we do the Udemy, we may as well add Flash Loans into the smart contract too lol.

[@22-Zar]

@@CryptoWizards Would be great, but does using this mean that every tx will create a new contract resulting in gas being much higher for each tx?

[@block1086]

that would be great@@CryptoWizards

[@karunnair8944]

Pls udemy....have u found edge in dex arbitrage?

[@CryptoWizards]

Ok will do. Haven't found an edge yet for manual trading. Working on it. Have found something on CEX which will update you on soon.

[@Liebendan]

When are you putting out arbitrage tradebot ui update

[@CryptoWizards]

Tricky one. Am struggling to find an edge for traders outside of stat arb right not. It's not so much the UI that's the issue but the method. Some new tooling is coming soon though on other stuff (listening to tokens being moved to exchanged on-chain etc) whilst I continue to dig.

[@Powner187]

Or you can ask them kindly to please leave you alone.

[@Cj-lf5mp]

I sent an email .. if you could check that and respond please that would be very much appreciated !!
