what is flash-usdt-sender fr?

This repository is a Python tool that creates cryptocurrency transactions described in the README as "flash" transactions: payments that appear on public blockchain explorers like Etherscan and in recipients' wallet balances for a configurable window of time (between 1 and 72 hours), but then disappear. The repository's own topic tags include terms such as "fake-balance", "fake-btc-transaction", and "exodus-fake-balance-tool", which describe what the transactions actually are. The tool supports several cryptocurrency networks: Ethereum (ERC-20 USDT and ETH), TRON (TRC-20 USDT), Binance Smart Chain (BEP-20 USDT), Bitcoin, Polygon, and Arbitrum. It includes a terminal menu interface, batch transaction sending, gas fee configuration, and the ability to broadcast through multiple nodes to increase the chance of the transaction being visible on block explorers. Configuration is done through a JSON file where you provide a sender wallet private key, choose a network, and set parameters like transaction duration, maximum amount, and how many RPC nodes to broadcast to. The codebase uses the web3 Python library for Ethereum-compatible networks and tronpy for TRON. The README frames this as a "multi-network flash transaction tool" without explaining the practical consequence: any recipient who sees such a payment and acts on it (for example, releasing goods or services) will find the balance gone once the window expires. This is the mechanism used in "flash loan" scams targeting cryptocurrency traders and exchanges. No legitimate use case is described in the README.
