poly-flashloan-bot's Issues

Error: replacement fee too low

I have found an arbitrage opportunity and it handed it over to the flashloan smart contract, but then it failed with this error message:

Error: replacement fee too low

Additionally, I have attached the log output thrown by the script, maybe it helps to investigate this issue.
log.txt

And there were 2 transactions on Polygon:

Do you have an idea why this error is happening and how to prevent it?

INSUFFICIENT_OUTPUT_AMOUNT error

I don't know how this error happened, but some people got this error when they change the config.

loanAmount: 10000000000,

Is it normal to have 10 billions in my transaction debug as loanAmount and I set only 10000 as loan amount

Does anyone make money with this bot?

Just curious to see if anyone makes money with this bot because the example contract that was actually deployed seems to only have failed transactions (not profitable).

Thank you

multiple errors

insufficient funds for intrinsic transaction cost among other errors.
there is 7 Matic balance in the wallet which based on previous transactions should cover the gas

Execution flashloan test

Hello! anyone knows how to test trigger a execution of flashloan to the blockchain just to see if it is working properly.. at least streaming a tx.. I found a few opportunities but no TX was trigger. Also I don't know where exactly is the profit calculator.

Thanks!

Fail with error 'SafeERC20: low-level call failed'

I made some changes to the code (but not the smart contract) and once it found an arbitrage opportunity and it called the smart contract, it failed with the above error message.

Is there something wrong in the contract, or did I do something wrong on my side?

Any help would be much appreciated.

A big delay from the bot to the contract

https://polygonscan.com/address/0xf651b785aa4aac0edcf2220ad88a9d2b52f640ff
Here is my contract and here were all the opportunities my bot found, but there was a big delay in between, anyone knows how to shorten it?

These are the opportunities it found today, but when it goes to the contract, each of them had an around 20 mins delay.

This is the opportunity it found 4 days ago, also had an around 20 mins delay.

[Feature request] Add log file to track events and failures

Would it be nice to have a log file that we can check that tracks all the meaningful events, like arbitrage opportunities detected with some related data or failures with stacktrace, that way we can help you debug the bot and report issues. Thoughts?

Finding best protocol for pair

Hi,
since you recommended not using 1inch anymore I started redesigning the bot. I encountered the problem that we don’t know the „best“ protocol anymore. Executing the bot for every protocol makes no sense since cyclic arbitraging needs more than one pair. So i tried finding the protocol by asynchronously checking all exchange rates and returning the highest rate giving protocol BUT this causes the bot to fail at some point if i set low intervals. To summarize all my tests with different strategies the last weeks: i didn’t quite found the best performing solution for this :) since your private bot is profitable I’m highly interested in your strategy of finding the protocol!

I will look into this myself, and I thank you for any help you can offer.

I got quite some transactions that just say Fail without further information. The bot seems to be running successfully, but somehow there is an error inside the smart contract. However, I have no idea how to debug this?

Fees Issue

Great bot here, thanks.

Once an opportunity is detected, i have (in my terminal) the table Flash Loans and the different opportunities in the table but nothing happens.

Should I have ETH or only MATIC in the wallet or in the contract?

Actually I have some MATIC in my wallet address but not any transaction is trigeered either in my wallet address or contract address and even on the 3 txns of the 3 opportunities at that time

Contract: https://polygonscan.com/address/0x1098b028Db5edDBD5f3b807D5F9Ea04B8268d342

seems to be the same error as before with the other contract, not sure how to troubleshoot this

Not enough amount to return loan error

The following error message is expected when you run flashloan with no arbitrage opportunities.
Fail with error 'Not enough amount to return loan'

When the bot says there's an arbitrage opportunity and run flashloan, the transaction gets reverted because of the above error.

Adding new pairs error

Attempting to add new (common) pairs; UNI, LINK I add addresses.ts entries, directly queried from 1inch Polygon API:

UNI: { symbol:"UNI", name:"Uniswap", decimals:18, address:"0xb33eaad8d922b1083446dc23f610c2567fb5180f", logoURI: "https://tokens.1inch.io/0x1f9840a85d5af5bf1d1762f925bdaddc4201f984.png" }, LINK: { symbol:"LINK", name:"ChainLink Token", decimals:18, address:"0x53e0bca35ec356bd5dddfebbd1fc0fd03fabad39", logoURI: "https://tokens.1inch.io/0x514910771af9ca656af840dff83e8264ecf986ca.png", },
and add trading pairs to config.ts:

export const tradingTokens = [
  ERC20Token.DAI,
  ERC20Token.WETH,
  ERC20Token.USDC,
  ERC20Token.USDT,
  ERC20Token.WMATIC,
  ERC20Token.UNI,
  ERC20Token.LINK
];

Results in the following errors during testing:

Fees calculation before send the transaction

Fees need to be calculated before send the transaction to avoid 'Not enough amount to return loan', 'INSUFFICIENT_OUTPUT_AMOUNT' errors... It would be nice if you can implement something like this:

Get Quote
Calculate each swap fees and add to it loan fees and ADD the slippery % (the one set in config.ts)
Check the difference of % or calculate amount and check amount diff.
If difference % or amnt is +n (this should be a const in config.ts to include/edit MATIC fees as needed) so send transaction BUT if difference % or amnt -n or = 0 so do not send the transaction

Actually when you swap 3 times in one transactions it can be 0.05x3 = 0.15 % fees on top of the flashloans fees 0.09%... Total 0.24% and.... slippery can add it on top again if the bot takes to long time to get the quote :) Eg: 0.24 + 6 = 6.24%

'const diffAmount' should be here MORE than 1000 + 6.24% or 62.4 USD to return to loan BUT we don't know how many swaps will be done before getting the quote so this const doesn't really help for now (but interesting to get it there).

Everything need to be done in milliseconds.

To avoid "high slippery" Im testing some auto rotation proxies services directly in the CallUrl... (I'm not a dev so I try easy way first) in order to increase transactions speed. I'll continue my tests...

With all of this we may have much less opportunities but at least we will be able to get a profit from them when their is big prices movements and to make it works.

For the first time the bot made a transaction on the contract ;) but returned a error Fail

"insufficient funds for gas * price + value\"}}","error"

I keep getting the above error. I have changed the gas from 30 to 150 to test if I needed to indicate a high gas price however it gives the same error at a price of 150.

Any suggestions?

Error Request failed with status code 400

Hi!
First of all thanks for sharing this code.
I am having an issue I cant solve when I use the command "yarn start". It says "Error Request failed with status code 400".
Can you please help me to sort that issue?

Thanks in advance.

the destination asset don't appear the information?

Thank you for your share!

When I run the code, the output don't have the destination asset info as below photo. Do you have any idea about it?

Edited but I haven't found a profitable arbitrage!

I really appreciate what you have done but I'm not agree with what you have write.

I've edited your bot, I have removed 1inch API and add call directly with dex smartcontract quote.
I have done 1 to 1 swap.

I have run bot for several time but I never have found a profitable arbitrage!
I share an example:

1 USD Coin -> 0.99924 Tether USD [UNISWAP_V3]
1 USD Coin -> 0.99549 Tether USD [SUSHISWAP]
1 USD Coin -> 0.99407 Tether USD [QUICKSWAP]
1 USD Coin -> 0.99723 Tether USD [APESWAP]
1 USD Coin -> 0.99868 Tether USD [JETSWAP]
1 USD Coin -> 0.99818 Tether USD [POLYCAT]
1 USD Coin -> 0.99812 Tether USD [WAULTSWAP]

0.99924 Tether USD -> 0.99899 USD Coin [UNISWAP_V3]
0.99924 Tether USD -> 0.99774 USD Coin [SUSHISWAP]
0.99924 Tether USD -> 0.99918 USD Coin [QUICKSWAP]
0.99924 Tether USD -> 0.998 USD Coin [APESWAP]
0.99924 Tether USD -> 0.99855 USD Coin [JETSWAP]
0.99924 Tether USD -> 0.99623 USD Coin [POLYCAT]
0.99924 Tether USD -> 0.9971 USD Coin [WAULTSWAP]

Request failed with status code 400

Thank you for sharing your code!

I have it up and running by following your instructions but I keep getting lots of errors like Request failed with status code 400. What am I doing wrong?

I am on the Polygon mainnet and the smart contract is deployed.

Thanks for your help.
