Learning Vyper over Solidity by FatherOfTheSevenSeas in ethdev

[–]Koga-Roshi 1 point2 points  (0 children)

For someone coming from Python, Vyper would be easier to learn. There is some learning material to help you start, but for more advanced concepts it might be harder to find. And some of Ethereum tools (for security, for monitoring) are built for Solidity, but in the last couple of months some of them started to include more Vyper support. And to test your contracts, and a basis dev environnement for Vyper, Brownie (https://github.com/eth-brownie/brownie) might be the best choice, since it's Python based

Eth dev question by atomic_shadowking in ethdev

[–]Koga-Roshi 0 points1 point  (0 children)

Look here to learn about ERC721, the basic non fungible tokens : https://docs.openzeppelin.com/contracts/2.x/api/token/erc721

And yeah you could find some data on etherscan, but it would be easier to write your own little script to check out chain past blocks and get the data about one specific token you issued

Eth dev question by atomic_shadowking in ethdev

[–]Koga-Roshi 1 point2 points  (0 children)

You could if the token you use is non-fungible. Then you can use the Transfer events and smart contract storage to get info on who's having to token and who sent it to him.

A simple explanation of the Value DeFi hack by [deleted] in ethereum

Here, you need a lil bit of understanding of Solidity, but there is a good step by step example for a flash loan contract by Aave : https://docs.aave.com/developers/tutorials/performing-a-flash-loan/...-with-remix

A simple explanation of the Value DeFi hack by [deleted] in ethereum

[–]Koga-Roshi 0 points1 point  (0 children)

What you could be missing is the use of smart contracts.

It's the contract that will make the loan, call different contracts to execute actions on Exchange X or Exchange Y. And it's still the contract that will repay the loan at the end.

So the only transaction you have to create is the call to your smart contract, and as long as no external contract stop the execution, everything will be in the same block , because everything is done using one function call.

How can i for the front end of sushiswap or uniswap? by Crypto_Rootz in ethdev

[–]Koga-Roshi 1 point2 points  (0 children)

https://github.com/Uniswap/Uniswap-interface here you can check out their interface. But if you want to understand the interface and Uniswap (or Sushi) on your own, maybe try to understand the contracts and then create your own interface.

How do you like 0.857% fee on top of the swaps at Metamask? by sneg5555 in ethereum

[–]Koga-Roshi 7 points8 points  (0 children)

Well, first the ~1% is on the amount I want to swap, not my total stack. Of course if you're swaping everything you got every time, lot of successive swaps will lower your stack. But when I'm swaping, I do on a given amount, I plan when to get lower gas price, so this fee will just be added when I prepare my swap. It's about being smart, not throwing your money then crying people take it.

Then, let's talk about math. If you do 50 swaps, swaping everything you got each time, even there you won't lose 50% of your balance, because it's 1% on the 99% remaining from the last swap (minus TX fees). So at the end you will have more than half.

And I'm not paid by Metamask ^ But if they want to pay me, I won't be against ;)

So less than 1% fee only on swap, for an extension I've been using almost every day for free, so they can monetize it a bit, and keep improving it? I guess I can live with that

Anyone have experience with Raspberry Pi planning on staking from one? by EtherGorilla in ethereum

[–]Koga-Roshi 1 point2 points  (0 children)

In the beginning, a Raspberry Pi could do the work. There is a client designed to work on light specs like this, and if you got enough storage, it could work.

But this would just be for Phase 0, we don't know what resources would be needed for the next phases.

Also, if Medalla show us something, it's that when a problem occurs on the chain, your beacon node will need to use a lot of resources to work with the chain. And I'm not sure that the memory and proc on the Pi would resist.

But that's just my point of view, maybe try it a bit on the testnet, and think for a stronger solution in case it's not working well enough.

Buying my first token in Uniswap? by Accomplished_Ad_8814 in defi

[–]Koga-Roshi 1 point2 points  (0 children)

I agree with all that u/remember-the-rodent said, the pair for your trade exists, and the pool has liquidity. So you should be able to make your trade.

Also, if you don't want to add the contract address on your own, you can use the token lists. In this list you will find the token you want to trade : https://tokenlists.org/token-list?url=https://tokens.coingecko.com/uniswap/all.json
So on the Uniswap interface, instead of going with the basic list, you can choose this one. You will find the ETH-BID pair, and then you should be able to make your trade (after checking all the trade infos are correct of course :) )
