He capitalized on the inefficiences of a new market due to liquidity issues. As crypto grows this will be less doable from as liquidity pools will be larger. So the idea is if you can write a smart contract that can return the original amount borrowed from the flashloan then you it goes through otherwise the smart contract fails you just lose the fees in gas. Its all resolved through DEXes and smartcontracts so its perfect arbitrage that can't fail basically.

If someone can create a token that monetizes this protocol it would be insanely lucrative. Better than YFI even. I've been talking about this "Atomic Arbitrage" for months now but don't understand enough of the technical to do it myself, just the process.

Saturn network is the only exchange I have found doing it but they have no volume which is lame because if people understood the profit potential it would be ridiculous. Arbitrage is healthy for a normal market as it tightens the spread between bids and asks stabilizing asset value

It would be nice to get a link to the full tweet to read more of the specifics. I'm assuming its probably all done via Metamask and a bot is doing all the swapping in an automated fashion.

I would imagine its probably achievable to calculate how new liquidity affects the price of a pool. Its all cryptography or math so I don't see why not. Uniswap.info has a lot of information, I'm not sure where the formulas are that dictate how the pools price assets though. I'm sure its out there somewhere.

Enlighten me then which part do I have incorrect. What I explained has been done already outside of OPs example. You can code a bot to identify arbitrage opportunities and then use flashloans to capitalize on the entire opportunity as it will give the liquidity necessary.

Its its all on DEXes and the entire transaction goes through smart contracts then it can be written to stop the execution if you can't pay back the flashloan when it the final step resolves.

I.E. You're bot identifies arbitrage through 3 different assets on 2 different DEXes. Lets say its a 4 steps and requires 4 contracts to execute if the arbitrage opportunity fails then it will automatically cancel and you lose the gas.

If it all resolves in the same block its legit. It seems like you don't get how they work.

https://cryptopotato.com/defi-flashloands-how-someone-made-16000-with-zero-investment/

"This is exactly what one user did, and he made $16,182 within seconds, using absolutely no investment but some pocket change for the gas fees.

Seen in block 10566089, what the user did was the following.

First, he borrowed 2,048,000 USDCT using dYdX’s flash loan. Remember, because it’s a flash loan, he doesn’t have to post any collateral as long as he repays the amount within the same block.

He then swapped this amount for 2,028,367 DAI on Curve y pool. After that, he swapped the DAI for 2,064,182 USDC on Curve’s SUSD pool, and lastly, he paid back the 2,048,000 USDC to dYdX, all within the same block.

All of this is possible because of the different stablecoin rate at the various lending protocols. And while 1% difference might not seem like a lot, when one is able to borrow high amounts and arbitrage this difference, the profits can be substantial."

You have to literally have constant tabs open watching volume and price to snipe this kind of arbitrage. The real arbitrage is the difference in ETH price across two stable coins, so you need to take the highest volume cryptos (BTC/XRP/ETH/LINK) and look for price differences across a list of trustworth stable coins, when you see a big difference you then need to very quickly find a liquidity path to get into one stable coin, into the crypto, and back into the other stable coin THEN a way back to the original stable coin. It's a lot of work and there are definitely people doing this as a full time job

Possibly. Again if you have an automated way to calculate the arbitrage through multiple assets then its hard to fail. DAI-USDC-TETHER-ETH-DAI or something along those lines for example. Then a bot to trigger the trades after identifying the potential arbitrage. So much fucking money you could make literally millions since flashloans require no collateral.

Bless you anon for this. New to crypto and never used eth/uniswap, but coded for 2 decades. You could implement this using eth web3 Node.js package, and probably there is an easy way to get a price feed to scan for arbitrage.

I just googled price scan feeds for the DEXes available on Furucombo and can't find anything. This is frustrating because I understand the process entirely and could dictate what I need done to someone who understand how to code but have no sense of the technicals.

>The clever way to run this would be let other people use your bot so they pay for the gas and to have the bot send you a percentage of their gains each time they succeed.

Yes that is brilliant. Some kind of fee only on their profit. How difficult would it be to code a bot that scans price feeds, finds the opportunity and then executes the flash loan arbitrage itself?

There is so much fucking money in these opportunities its unreal and they are never ending. You are just limited to all the DEXes basically for the potential trades so your bot would only scan prices from them.

Anon I must sleep, and the thread will be archived at some point...

1. Get a price feed for your target DEX exchanges. This will probably be the biggest pain of the entire project because you have to look for their API or SDK and convert their data feed into something that your code can read. It will give you data in JSON format, possibly through something called WebSocket.

2. Compare the coin pairings between the two DEX prices each time you get new data from the price feeds. If favorable pairing, initiate a transaction. This is the easiest step.

3. Generate an ether transaction. Also a potential pain in the ass, because you have to figure out how to interact with SmartContracts. Totally doable, just have to read lots of docs.

I think you can do this purely with javascript which is forgiving and user friendly. I know Ethereum has a javascript SDK called web3.js. WebSockets/JSON are standards. All of the info and documentation is out there! Godspeed anon

Reason I ask is that it would be interesting to collect all the data and then determine whether any AMM platforms are getting hit harder than the others. Right now the effects of arbitrage are minimised by exchange and gas fees, but if/when it's more frictionless, we might see whole AMMs getting drained. I'm particularly interested in the Bancor AMM 'ratchet' model that might end up drawing liquidity from other platforms, or might be sensitive to a growth-then-catastrophe attack vector.

Dude thanks I'll look into this. I was setting up a Meta Mask strictly for arbitrage. I have a lot of time to learn because I trade futures for income anyway. I'm on /biz like 5 hours a day so if you tinker around with this and have future success please make a thread!
