Anyone know what's command for truffle to get ETH in wallets generated by truffle?

I think faucet is the only way

Anyone have some links to existing ERC 20 tokens, basic and advanced with extra functionality? should be secure and errorless

He could also run on mainnet-fork a unlock the account he wants .

Hmm👍

The solution is to run the ganache script with argument , if network fork and unlock the desire or work with the generate account . truffle doesn't generate account, it's ganache

What? but I ran truffle migrate and it generated accounts and deployed on local mainnet

If I didn't install ganache even then it worked

truffle needs ganache to generate accounts, ganache play the role of local rpc, how could you deploy without rpc ?

Tbh I don't understand JSON-RPC properly

Is RPC blockchain specific?

So, I am here using ganache without explicitly using ganache commands, but sometimes we do that, using ganache commands on console, what's the difference and when we do that?

Maybe weird question

I don't really understand your question, if you want to deploy on mainnet you don't need ganache but you need ganache to work on local, or network fork .

you can deploy your contract , interact without running ethereum client on your computer with infura, alchemy depending on your truffle-config.js but if you want to unlock and have main control on the chain you need to run a local rpc or fork deployed one , you can use truffle + ganache or hardhat to do the task

it's a bunch of time I didn't use truffle , maybe someone could have better explanation than me

Thanks👍

contract Context {
function _msgSender() public view returns (address payable) {
return payable(msg.sender);
}

function _msgData() public view returns (bytes memory) {
this; // silence state mutability warning without generating bytecode - see https://github.com/ethereum/solidity/issues/2691
return msg.data;
}
}

Anyone understand how 'this' keyword silencing warning?

// silence state mutability warning without generating bytecode

I don't understand this, what does it mean by without generating bytecode? I want to know how it can be done with generating bytecode

@NeoMitashi ?

@grimreaper619 Can u pllease explain this?

On slither analysis it would show some issue I guess, to prevent that they build a separate function

What does signing transactions mean? where we don't pay gas?

On open sea many times I do that but don't know what happens behind the interface

if it's action like approving coin on AMM, then we should pay gas for that?

Signing transactions are basically making some bytes with the function data and your private key

Or we just reading data from blockchain with view or pure function?

It takes gas fees to process that data on blick chain

What does it mean in simple words?

Just siging a paycheck

You dont have to pay money to sign

But have to pay to make that transaction

Public key and private key are related.

We can check if a transaction was signed with the public key but cant sign one.

So you can see why we should keep our private key safe

But if this sign is not on blockchain then how's it immutable?

Your private key is immutable

It doesn't have any properties of blockchain

Its how blockchains work

Its the main core element

So why not make every blockchain transaction off chain, so I don't have to pay gas fee, and it's immutable as every wallet has their own private keys?

But how can we know if a transaction is signed of not

And where these off chain txn stored?

There is no off chain txn

You can understand what im saying if you know how bitcoin works

Just don't use a blockchain and you solved lol

Without that it'll complain to make it pure

Just read the white paper

I have made these kinds of clicks on metamask while interacting with some Dapps -
1. Transfering tokens
2. Swapping tokens
3. approving tokens
4. Minting NFTs
5. Sign(only gasless click I made)

Sign allows metamask to make transactions

Oh I haven't gone through it's whitepaper, was trying to find a time window to through that, Will do that thanks..

Ye it will give you a good understanding of how block chains work

👌👌

👍👍

There is a nice book by gigi as well

Nice

I am thinking of going through that as well

👍

I don't have proper understand of nodes as well

I think I will need node if I want to use arbi bots?

or It can be helpful as well, if uniswap down on my side

some people do that

Ye

I dont think you need a full node.

Arbitrage requires (depending on how you do it) creating smart contracts that interact with multiple protocols, scanning prices and then executing on opportunities. You could also implement flash loans by calling certain contracts in a DeFi protocol like Aave

I want to try out all that, but I think it will take time to me😅. I am still struggling with web2 backend and web3

But will ask for help on arbitrage when needed👌

Are you using node.js?

Yeah

👍👍

Thats fine but Im more suggesting shortcuts to what you wanna do. You dont have to build a blockchain to interact with DeFi protocols

Look up moneylegos and it gives you a rundown on flashloans and arbitrage

Are there any resources for arbitrage? I want to get started with it while I'm learning things

Sure thanks

How much time it took to you brother? to get at this stage😅

There was a paper called FlashBoys 2.0 which goes into detail what goes on in arbitrage bots

I dont use node.js. i mainly use python

https://arxiv.org/abs/1904.05234

But ye i will learn web development within the next 3 months

Still you have running bots successfully haha

I understand theory behind it, I just want to into practical now

Web3 is avilable in python

Totally fair. I guess I made an assumption you weren’t familiar because you brought up nodes.

When did u started with solidity?

3 months ago

Gave a quick google

https://github.com/ExtropyIO/defi-bot

Im personally still confused on interacting with protocol interfaces (which what money-legos helps with) which is holding my implementation of arb bots back

Thanks a lot🙏

Nice mate

Oops

Wasn't intentional :)
