    # Build an Advanced DeFi Flash Loan Arbitrage Bot (BSC) ## Project Overview I'm looking for an experienced Solidity/DeFi developer to build a high-performance **Flash Loan Arbitrage Bot** for Binance Smart Chain (BSC). I have already completed extensive research and reverse engineering of an existing deployed smart contract to understand its architecture and transaction flow. I also have live on-chain transaction history and contract interactions for reference. The objective is **not to clone or copy** an existing contract, but to develop a new implementation with similar trading logic, improved architecture, better gas optimization, and enhanced security. ## Available References I will provide: * Decoded contract source for research * Dedaub analysis * Live deployed con...

    I need help crediting my Redotpay wallet with USDT. The balance will be coming from my own personal wallet. For the network, I indicated “Redotpay” because the app itself does not make the underlying chain obvious, so I will rely on you to confirm whether I should send over Ethereum (ERC-20), Tron (TRC-20) or Binance Smart Chain (BEP-20) based on fee structure and compatibility with Redotpay’s deposit addresses.
