Sweeping Task

Overview

This project implements an automated sweeping process for aggregating crypto assets (USDT and ETH) from a group of N Ethereum wallets into a primary (main) wallet

After sweeping, all ETH and USDT balances from auxiliary wallets will be consolidated into one main wallet, and the balances of the auxiliary wallets will be left at zero

Problem Statement

1. N ethereum wallets are provided: A1, A2, ..., An
2. Each wallet may contain arbitrary amounts of USDT (ERC-20) and ETH
3. The main wallet is defined as A1
4. The goal is to transfer all ETH and USDT from A2, ..., An to A1
5. If an auxiliary wallet lacks sufficient ETH to cover transaction (gas) fees, it must be topped up from the main wallet before sweeping its assets

Acceptance Criteria

1. SweepingService interface fully implemented
2. All tests pass successfully (yarn test)
3. Merge request is accepted and reviewed

Environment set up:

yarn
yarn test
