I'm trying to understand solidity, the code contains functions that given unit values, returns an ETH address. What interests me is someone who explains the code to me and who creates a code that does the inverse function, i.e. given an address value (ETH) it returns the unit value I only consider the proposals containing the phrase "solidity unit code" I will send you the code privately

I would like to create a front-running sandwich bot based on Ethereum Block Chain with different contracts address that can be entered (Metamask, eth network). (Uniswap v2&v3) The BOT would essentially: - Scan the blockchain and find transactions based on certain criteria (pending on the block aka mempool). - Front-run (specific trade volumes, slippage and gas price) transactions by placing a buy order on the same block at the same time by setting a higher gas price automatically. - and buy up only to the maximum value (I set it manually (ETH)) that I have decided to trade and when only has x % (I set it manually) profit by calculating through the pending transaction amount(impact that it has his/her investment) & gas fees selected automatically & slippage (buy&...

Hi there! I am looking for a developer to build a DAO platform with smart contract. The main purpose of the platform is voting, so the ideal candidate should have experience in creating voting systems on blockchain. I'm on the lookout for talented developers who know their way around Golang, smart contracts, and Python. I've got an exciting blockchain-based project lined up that involves building a snazzy Golang backend, implementing smart contracts, and dabbling in Python frontend development. I prefer the use of Binance Smart Chain as the blockchain platform. If you're intrigued and have the right skills, hit me up to dive deeper into the details! Let's make something awesome together.

We need to register a .SOL domains using an api. You will implements only two operations: a) Register .SOL DOMAIN: Boolean result = registerSOLDomain(String domain_sol, String phantom_Wallet_private_key). result = true if the domain was registered or false if not (show error). b) Transfer .SOL Domain from a wallet to another wallet: Boolean result = transferSOLDomain(String domain_sol, String phantom_Wallet_source_private_key, String phantomWalletDestinatiob). result = true if the domain was registered or false if not (show error). To implement this project only free resources can be used .That is, we will not use features like quicknode, infura etc. It is all. We already know which domains we want to register and we know which domains are available.

Hi, I need a small Python program that will take the EVM bytecode of a smart contract as input and then will use the open-source Mythril package to analyze the bytecode for detecting bugs in the contract. The program should be simple, and there shouldn't be any installing issues with Mythril. Open to any alternative suggestions for tools that can analyze bytecode for detecting bugs if you can do it quickly. Please reach out if you are interested and have experience. PLEASE DO NOT JUST COPY AND PASTE FROM CHATGPT! Mythril Package: Thank you.

Hello, We have front end coded: Connects wallet, checks both USDT and PLS on pulsechain wallet balances and prints to screen. Also prints current PLS to screen and has conneted wallet ID. We need blockchain code: That upon clicking swap button on html page will take USDT entered from connected wallet and send to USDT cold wallet using gas PLS from different cold wallet. It will then send PLS amount from PLS cold walle to connected meta mask wallet.

Estou buscando desenvolver uma funcionalidade para o meu site, que atualmente aceita pagamentos apenas em Tether (USDT) BEP-20. Quero um similar ao que é feito no PixSwap (). Eu gostaria de permitir que meus clientes comprem USDT diretamente de mim, usando a API da PancakeSwap para a compra de tokens e a API da EFi (antiga Gerencianet) para processar pagamentos via PIX. Além disso, pretendo cobrar uma taxa sobre cada transação. O fluxo de trabalho seria algo assim: O usuário entra com a quantidade de USDT que deseja comprar e o endereço da carteira para onde deseja que os tokens sejam enviados. O sistema usa a API da EFi para processar o pagamento via PIX. Uma vez que o pagamento é confirmado, o sistema usa a API da PancakeSwap para compr...
