extropyio / defi-bot Goto Github PK

Hello after 2 days of correct operation yesterday the system sent the ETH without having anything returned, is it normal that sometimes it takes time or have the funds been lost? What could have happened?

https://etherscan.io/address/0x6856ce0acf5Bb0817B4cD5c183073C261bA8Be38

I’m very new to this coding thing, but I really wanna learn and thought this project could help me learn, but when I tried to run it it threw this error: syntax error: unexpected identifier.
I can’t understand anything can somebody please help me how to set this bot up.
When I opened it up I just made a .env file and filled it nothing more.
Do I have to do anything more or what. Im completely lost at this point.

I'm getting this error whenever I run the index.js bot and I'm not sure what the solution is. I've tried defining 'address' in the code where it's throwing the error, and it still says the same thing.

Bye

What the title says. Really keen to understand the code!

I've done all the steps to set up the node.js bot and have added the info to my .env file but it keeps throwing this error:

internal/modules/cjs/loader.js:883
throw err;
^

Error: Cannot find module 'dotenv'

  }

none of the files have been moved around, although I did copy the .env file into the root directory as well as the \src folder just to be sure it could find the file it is looking for. Has anyone else come across this issue? What do I need to do so that it can find the file?

I get the below error when deploying to Sepolia testnet.

"TradingBot" hit a require or revert statement somewhere in its constructor. Try:

• Verifying that your constructor params satisfy all require conditions.
• Adding reason strings to your require statements.

Any insight into resolving this?

I've been getting these error messages after importing the required libraries. I've been trying to fix this however the debug isn't much help and just directs me to line 5 of the bootstrap-fork.js file.

Thanks. Also, codemedici I appreciate you helping me out last time even though my question was pretty simple. I'm using this bot as a means to help teach myself to code. Figured I'd get more enjoyment out of it if I'm working on something I actually care about.

Hi,

First off thanks for putting this together. It has been extremely useful in better understanding Smart Contracts and Arbitrage in general.

I'm currently using the project as a basis to create my own bot in Go.

Currently when I run the node app I get an Insufficient Funds error whenever an arbitrage opportunity is detected.

Error:

My Config

RPC_URL="https://mainnet.infura.io/v3/<apikey>"
ADDRESS="0x<my account hash>"
PRIVATE_KEY="0x<my private key>"
CONTRACT_ADDRESS="0x<my deployed contract hash>"
GAS_LIMIT=3000000
GAS_PRICE=400
ESTIMATED_GAS=1700000

The account I'm using currently has a balance of 0.8 ETH

I have tried reducing the FLASH_AMOUNT variable in the script as I believed maybe it was trying to borrow more than it could actually afford, but even with the value set to 1 ETH, I still get the same error.

I also noticed that the Input value shown in the table is always 0.00128. When I print out the non-profitable values, the inputs vary, but only the input value above seems to show up when a profitable arbitrage is detected.

Is there something i'm missing here?

Thanks in advance

Transaction keeps reverting with the error "Fail with error 'OneSplit: swap makes no sense'"

https://etherscan.io/tx/0x35c7e07964a90184d8f3571ae4b5d6b976b978b55f306cd21dcfeca39e5eff49

It seems the error is being thrown from OneSplit's swap function

function swap(
        IERC20 fromToken,
        IERC20 toToken,
        uint256 amount,
        uint256 minReturn,
        uint256[] memory distribution,
        uint256 featureFlags // See contants in IOneSplit.sol
    ) public payable {
        require(fromToken != toToken && amount > 0, "OneSplit: swap makes no sense");
        require((msg.value != 0) == fromToken.isETH(), "OneSplit: msg.value shoule be used only for ETH swap");

        uint256 fromTokenBalanceBefore = fromToken.universalBalanceOf(address(this)).sub(msg.value);
        uint256 toTokenBalanceBefore = toToken.universalBalanceOf(address(this));

        fromToken.universalTransferFromSenderToThis(amount);
        fromToken.universalApprove(address(oneSplitImpl), amount);

        oneSplitImpl.swap.value(msg.value)(
            fromToken,
            toToken,
            amount,
            minReturn,
            distribution,
            featureFlags
        );

        uint256 fromTokenBalanceAfter = fromToken.universalBalanceOf(address(this));
        uint256 toTokenBalanceAfter = toToken.universalBalanceOf(address(this));

        uint256 returnAmount = toTokenBalanceAfter.sub(toTokenBalanceBefore);
        require(returnAmount >= minReturn, "OneSplit: actual return amount is less than minReturn");
        toToken.universalTransfer(msg.sender, returnAmount);

        if (fromTokenBalanceAfter > fromTokenBalanceBefore) {
            fromToken.universalTransfer(msg.sender, fromTokenBalanceAfter.sub(fromTokenBalanceBefore));
        }
    }

More specifically, this line here
require(fromToken != toToken && amount > 0, "OneSplit: swap makes no sense");

My guess is that the amount being passed is less than zero in the TradingBot contract.

Does anyone have any ideas what might be happening or how to work around this?

In the Readme file -> Method Section -> Detailed Setup, 3rd point says to...
"Go to Remix online IDE and paste the smart contract solidity code",
What exactly should I paste there I didn't get it. And are there any files that should be created there or I need to paste some code from this repo there?

if ı try deploy code from remix , ı have this issue :

"UnimplementedFeatureError:"

why and what can ı do ?

sudo node src/index.js

i get this error everytime i try and launch from the root directory, any suggestions?

I cannot deploy the TradingBot.sol contract on the blockchain networks (I have been using Kovan and Ropsten test networks) on Remix IDE. Remix is giving me an the error:

"Gas estimation errored with the following message (see below). The transaction execution will likely fail. Do you want to force sending?
execution reverted"

I am using compiler version 0.5.17 as suggested by the documentation.

When I send anyways, the contract fails. The failed contract deployment transaction can be seen here : https://ropsten.etherscan.io/tx/0xa632f0d856ed5de32e45e5bcaad1e9a976f9565b752f8f8697d5732b76912e2a

I have tried increasing gas limit, but the error still appears.

Additionally, when I compile the TradingBot.sol, I receive two warnings,

TradingBot.sol:2:1: Warning: Experimental features are turned on. Do not use experimental features on live deployments.
pragma experimental ABIEncoderV2;
^-------------------------------^
TradingBot.sol:307:9: Warning: Return value of low-level calls not used.
address(ZRX_EXCHANGE_ADDRESS).call.value(msg.value)(_calldataHexString);
^---------------------------------------------------------------------^

Is there a solution to deploy the TradingBot.sol?

A few things I've tried:

• Put a semicolon and comma at the end
• Disabled TypeScript and JavaScript Language Features

Typescript version 4.3.4
VS Code 1.57.1
Windows 10

Any ideas on what the actual issue is, and how to fix it?

Thanks

Hello, im having 2 problems when deploying the TradingBot.sol.

First is in line 2: "Warning: Experimental features are turned on. Do not use experimental features on live deployments. Pragma experimental ABIEncoderV"

second is in line 306: "Warning: return value of low-level calls not used. Address (ZRX_EXCHANGE_ADDRESS). call.value.(msg.value)(_calldateHexString);"

Can someone help? ty

Hi there,

Please is it possible to run this bot on a testnet?

Thanks,
Babs

Hi thanks for the article and code. The challenge i have is getting the optimum value for Gas for Arb. How much is sufficient is the value provided in .env is the right values ? It turns out to be too much cost from a txn fee prospective.

I'm running the bot in an ubuntu ec2 instance and when it finds an opportunity and attempts a trade I get:

Error: Invalid JSON RPC response: "<html>\r\n<head><title>504 Gateway Time-out</title></head>\r\n<body>\r\n<center><h1>504 Gateway Time-out</h1></center>\r\n<hr><center>Microsoft-Azure-Application-Gateway/v2</center>\r\n</body>\r\n</html>\r\n"

Am I needing to open up ports on my security group on my ec2 instance or something?

Hi guys and gals,

I was able to successfully deploy the TradingBot.sol contract to the mainnet (after many unsuccessful attempts on Ropsten and Rinkeby). Then I wanted to get index.js to run. After commenting out line 327, I did a yarn install and npm install in the directory and then ran node src/index.js. However I always get the following error messages in return:

Fetching market data @ 2021-08-02T11:18:22-05:00 ...
