paco0x / amm-arbitrageur Goto Github PK

pancakepair 调用swap的回调函数名是pancakeCall,这个代码里面是uniswapV2Call ,还是其他交易所的函数名很多都改了

I clone sourse code
and set bsc wallet in .secret.ts

depoly flashBot contract with remix editor and set contract address in config.ts

after use this command in command promt (windows 10)
yarn run bot
I have this error:

前面那个issue关掉了呀，请问一下： 要怎么把赚到的token从合约里提出来？ 是要先verify合约代码，还是直接用什么命令直接通过js代码提取呢？

When running the bot it seems to only access the base token price. My only output has been as follows. Any idea why this might happen?

Hi
I'm really really new here and no any knowledge about developer skill. now i have ubuntu server and already clone project to my local server. I just need to know how to install hardhat to amm-arbitrageur folder cause the instructor of hardhat need to install in empty folder and i tried to run "npx hardhat with amm-arbitrageur that located any file from github but it's show error like no hardhat to be executed. question is how to install hardhat in amm-arbitrageur and run it.

Whats does at mean? ı am waiting about 10 minutes

When running deploy.ts I get an error about insufficient funds.

You can find the contract here:
https://bscscan.com/address/0x9523719805da3c7123f8379f1e82c8e33b993595

The first transaction was reverted with an error: No Profit
But then all the succeeding transactions are reverted without giving any reason. Is there an error in the code? Or am I doing something wrong?

能改成用websocket吗，当前这个默认的rpc感觉很慢

I run npx hardhat test and found this problem

1. 看到一些bot，有用到chi token用来支付gas费，从而减少很多gas,请问这个代码怎么修改可以做到这点呀.
2. 类似下面这个bot，成功率很高，请问怎么可以做到提高成功率？
3. 类似下面这个bot，为什么要先转成busd再转成bnb?
   

Hello. Thank you for your work!

Can you direct me which files I need to modify to add third pair in trading?
like:
token - base | base - base | base - token
token - usdc | usdc - weth | weth - token

I see it should be:
generating pairs than
calculate trading with generated pairs
that trade through three pairs

Thank you for advice.

hi all
i have a question when i run hardhat test it's show error log below. Who's can tell me how to solve it.
MathTest
#sqrt
1) "before each" hook for "calculate square root correctly with small input"

Flashswap
flash swap arbitrage
2) "before all" hook for "do flash swap between Pancake and MDEX"

I input my public and private keys both with and without quotes and either way i keep getting the same error. What format should i be using?

Error: network does not support ENS (operation="ENS", network="unknown", code=UNSUPPORTED_OPERATION, version=providers/5.1.0)

how can I get negative profit?

Is this due to fees?

63         if (err.message === 'Too much pending tasks' || err.message === 'async-lock timed out') {
               ~~~

63         if (err.message === 'Too much pending tasks' || err.message === 'async-lock timed out') {

Seems it got some unexpected error? Do anyone have any idea how to deal with it?

Edit: by viewing debug logs, it seems to be the problem of cannot estimate gas; transaction may fail or may require manual gas limit, which due to "deprecated token pairs". I wonder is there a good way to know which token pairs are not deprecated?...

Hey!
I'm trying to run the script but i'm getting Out of gas error on the flashBot.getProfit call.
I have coins both in my wallet and in the contract itself

Hi,
I have tried many front-running and arbitrage scripts from Github. I also modified it (use to MySQL to store the spotted potential pairs so that next round I can check in DB if match it can start the arbitrage directly instead of check all again & again).
I also deployed a full node on AWS i3.xlarge instance, I run the script in that VPS. I managed to run the attack just less than 50 mini seconds after the bot spotted an opportunity and fire a transaction to a smart contract written by me. The smart contract will execute the Tx if it check it is profit and revert the transaction if it is not.

Here is the summary I can tell:

1. When the bot spot an opportunity, let say you can buy BNB cheaper in ApeSwap and sell higher price on Pancakeswap. Current block is 19000, so when you send a transaction now, it will be ALWAYS at least in block 19002 (2 blocks behind because BSC have Min of 2 blocks or 6 seconds confirmation). So the opportunity you spotted on block 19000, you are impossible to send a transaction there (because it already passed at least 6 seconds when your Tx is confirm)

2. Even you listen to the pending transactions events using Web Socket with web3 (which I done), and repeat the same process, my Tx is ALWAYS at least 10 position behind a spotted Tx. And there is always one Tx that just sit ONE position behind the spotted Tx. Which it is nearly impossible to done by people like us, the most possibility is those running as validator which are able to place and re-arrange the Tx orders when their validate the transactions. You can go and search MEV issues on Ethereum, BSC or Polygon. Because i believe even I upgraded the AWS instance, I still can't win whose guys because all the transactions at the end are being validated on their full node. And surely they already modified their GETH so that they can re-order the TX and place their Tx just any position they like in the block their validating... So no matter how good is your bot, you will never win in the race. The only way you can win is become one of the validator and changing the Tx order on it lolx...

You must think out of the box, or other way to run it. This is what I have experienced and doing research to find out. If anyone interested can contact me at TG @PancakeSwapUniSwapBot and we can discuss more.

Hey first of all, thanks for the code. I was able to deploy the contract and start the bot. the pair file was created and is very extensive. A successful transaction is performed every few hours. so in general it works.However, when I run the bot in debug mode, I can see that it is not running properly.

On the one hand, this error occurs 90% of the time:

2022-07-12 09:01:45 debug: call revert exception; VM Exception while processing transaction: reverted with reason string "Complex number" [ See: https://links.ethers.org/v5-errors-CALL_EXCEPTION ] (method="getProfit(address,address)", data="0x.......00000000000000000000000000000000000000000000000000000000000000020000000000000000000000000000000000000000000000000000000000000000.............000000000000000000000000000000000000", errorArgs=["Complex number"], errorName="Error", errorSignature="Error(string)", reason="Complex number", code=CALL_EXCEPTION, version=abi/5.6.4)

(... for parts of my contract adress)

On the other hand, many calculations are simply 0.0 : Profit on CAKE-WBNB: 0.0

lp addresses were generated correctly in the pairs file.

Do you have ideas for the issues? I've tried many things

I see a profit between the two pair
profit: 0.059353947220959595
'0x5010dA63eBD45D833258cca1FEFB7715c16708c2', '0x223740a259E461aBeE12D84A9FFF5Da69Ff071dD'

config
minimumProfit: 3, // in USD

I called the flashArbitrage manually
But the transaction went fail
Was the amount of profit small?
How is the loan amount obtained, can it be changed for max profit?

I use bsc network

code:

const tokens = await flashBot.getBaseTokens();
  console.log('Base tokens: ', tokens);

  const res = await flashBot.getProfit('0x5010dA63eBD45D833258cca1FEFB7715c16708c2', '0x223740a259E461aBeE12D84A9FFF5Da69Ff071dD');
  console.log(res);
  const [baseTokens] = getTokens(Network.BSC);
  const netProfit = await calcNetProfit(res.profit, res.baseToken, baseTokens);
  console.log('profit: ', netProfit);

  const lock = new AsyncLock({ timeout: 2000, maxPending: 20 });
  try {
    // lock to prevent tx nonce overlap
    await lock.acquire('flash-bot', async () => {
      const response = await flashBot.flashArbitrage('0x5010dA63eBD45D833258cca1FEFB7715c16708c2', '0x223740a259E461aBeE12D84A9FFF5Da69Ff071dD', {
        gasPrice: config.gasPrice,
        gasLimit: config.gasLimit,
      });
      const receipt = await response.wait(1);
      console.log(`Tx: ${receipt.transactionHash}`);
    });
  } catch (err) {
    if (err.message === 'Too much pending tasks' || err.message === 'async-lock timed out') {
      return;
    }
    console.log(err);
  }
}

But the wrong transaction was made
I checked the pair of contracts to see if the pool has a deal
But I saw that many hours had passed since their last deal

Please help me why this profit has been shown but transaction Fail while no transaction was made in the pairs contract

你好，比如我想监控一些safe，动物系列的币。 tokens.ts和pair-bsc.json都要改么？ 要加些什么呢？

I've made a simplest python test based on the formulas here:

import math as m

r01_0 = 10*10**9

r10_1 =  15*10**9


a1 = r01_0
b1 = r01_1

a2 = r10_0
b2 = r10_1

a = a1 * b1 - a2 * b2
b = 2 * b1 * b2 * (a1 + a2)
c = b1 * b2 * (a1 * b2 - a2 * b1)

m_ = b**2 - 4 * a * c

sqrtM = m.sqrt(m_);

x1 = (-b + sqrtM) / (2 * a);
x2 = (-b - sqrtM) / (2 * a);


if x1 > 0 and x1 < b1 and x1 < b2:
    amount = x1
else:
    amount = x2

print( f'opt_in: {amount:.2f}')

    amountOut = numerator / denominator
    return amountOut

Hi,

Can you elaborate on where the first set of formula's come from: \delta a_1 = \delta b_1 * a1 / (b_1 - \delta b_1) ?

Thanks!

Ygor

Why is it showing error during "Flashbot.sol" compilation?

https://github.com/paco0x/amm-arbitrageur/blob/master/contracts/FlashBot.sol#L320

|| 两边的代码是一样的，没有判断x2。

另外感谢作者的付出🙏

如果我是自己搭建BSC网络的节点，那么服务器的区域选择有差别吗？比如东京阿里云和香港阿里云，只要我的套利程序跟自建的BSC节点在一台服务器上，跟服务器的地理位置应该没啥关系吧？

Hi all,
i am trying to deploy this project but i get this error

``
Creating Typechain artifacts in directory typechain for target ethers-v5
An unexpected error occurred:

Error: Couldn't find ethers-v5. Tried loading: @typechain/ethers-v5, typechain-t arget-ethers-v5, /root/Desktop/amm-arbitrageur/ethers-v5.
Perhaps you forgot to install @typechain/ethers-v5?
``

i have already do
npm i @typechain/ethers-v5 npm i typechain-target-ethers-v5

Hey,
Thanks for the awesome project!

I've modified the bot a bit to increase chances of profit.
It did report a profit of +$100 and showed a transaction hash.
But I can't find the money anywhere.
The contract value on bscscan is saying $0.01.

I tried creating a simple script:
const res = await flashBot.withdraw(); const receipt = await res.wait(1); log.debug(Transaction: ${receipt.transactionHash});

But nothing is received, not even a transcation hash.

Any idea what could the problem be?

deploy.ts 中 const flashBot = await FlashBot.deploy(deployer.address) 的 deployer.address 我填写的是自己的钱包地址，
看到 flashbot.sol中，这个地址应该是 weth（wbnb）的地址
constructor(address _WETH) {
WETH = _WETH;
baseTokens.add(_WETH);
}
是否存在问题？

Hey your repo is my first time messing with BSC. When I try to deploy I get the following Error. Would appreciate any help because I'm sure I'm missing something obvious. Thanks!
Invalid value {"url":"https://bsc-dataseed1.defibit.io/","chainId":56,"accounts":["MyPrivateKey"]} for HardhatConfig.networks.bsc - Expected a value of type HttpNetworkConfig.

i am willing to pay for it

fallback(bytes calldata _input) external returns (bytes memory) { (address sender, uint256 amount0, uint256 amount1, bytes memory data) = abi.decode(_input[4:], (address, uint256, uint256, bytes)); uniswapV2Call(sender, amount0, amount1, data); }

would this be a solution?

Hi I’ve really enjoyed this repo and learned a lot from playing with it. I had two questions about things I haven’t quite figured out. One is that I see a lot of pictures in issues of the logger, how do I access that log page while running the bot. I’m a scrub. Also, an error I’ve received a lot of on Matic specifically is “wrong pair order” and while I see this in the contract I’m not sure I can really figure out why it happens. Appreciate the repo immensely it basically taught me how to use ethers library which has been amazing.

Flashbot.sol line 313 应该为 int256 a = a1 * b1 - a2 * b2； ？？？

Hi,

I'm wondering how it know our contract address after scripts/deploy.ts

当前我用we3.py包来用Python调用这个合约，想withdraw，当时因为它的合约没有验证，所以abi显示不出来，我就在python里面创建不了contract对象，接着无法调用withdraw了。

作者您好，请问怎么调用withdraw呢？ 可以写个加个withdraw功能在github的bot里面，或者web3.py版本的脚本？
可以大概讲一下
