ERR_INVALID_URL

[manseth]

Hi. I just tried to use your bot but when i run the node run-arbitrage.js i get this error. I assume i need to put my web3 infura URL but i can't find where. Could you please help me ?

`~/Defi-Arb-Bot$ node run-arbitrage.js
internal/url.js:257
throw new ERR_INVALID_URL(input);
^

When i run the command "truffle migrate --network mainnet --reset" i get this

Truffle v5.1.50 (core: 5.1.50)
Node v12.19.0`

then i run the "node run-arbitrage.js" and i get the same "ERR_INVALID_URL".
I have already create a .env like this in the root folder and still get the same error

INFURA_URL=wss://mainnet.infura.io/ws/***************************** PRIVATE_KEY=ac**********************************************

You can notice i get a ""Flashloan" could not deploy due to insufficient funds" but the total cost is 0.016277652 ETH since i have a lot more than that in my wallet.

hey man, sorry for the late reply. but look at this line here:
https://github.com/olegmitrakhovich/Defi-Arb-Bot/blob/master/run-arbitrage.js#L8

you need to make a ".env" file and inside that file just write "INFURA_URL="

[olegmitrakhovich]

as for your gas issue, 0.016277652 ETH is way too cheap.. I had to pay 90$ bucks to deploy this thing, keep playing with the gas fee and make you have atleast 1 ETH in your account.

[manseth]

No worries, okay that's what i have done i have create a .env file and i have put inside my infura url + private key and and i still get the error when i run the node run-arbitrage.js :( but when i run truffle migrate --network mainnet --reset the only error it's for the gas.

How can i change the gas fee ? On the script or on my wallet ?

Sorry if my questions seem dumb but i'm "new" to this.

EDIT:
OKAAAY i understand let me explain

The problem of fees is due to the fact that "truffle migrate --network mainnet --reset" could not finish because I do not have enough ETH on my wallet so the 0.016277652 is only a part of the total amount to deploy the contract the total amount being about $ 90 as you said.

[olegmitrakhovich]

lol not a problem, no such thing as a dumb questions. its kinda cool that people are trying to make this code work, so I'm flattered. Also check this line again : https://github.com/olegmitrakhovich/Defi-Arb-Bot/blob/master/run-arbitrage.js#L8

make sure the variable you are using is right, because I switched to QUICK_NODE recently. Make sure you are using the right name for your variable.

[manseth]

Okay i will replace infura by quick node. Thank you for your answer !
And one last question, when the contract is deployed (i assume you done it) did you make any profit from it ? If yes that's very good but if no what should we for make profit from it ?

[olegmitrakhovich]

no I didn't make any money, if anything I lost money lol. That's why I posted the code here to see if someone can tell me what's going on. The prices I am getting are wrong for some reason...wrong or my bot is not fast enough to do the transaction ... take a look at other issues. People forked this code multiple times so I'm hoping to through their stuff soon and see if I find anything.
