Viem Sweep

Overview

This skill provides implementation patterns for advanced transaction strategies using viem v2. It covers methods for moving assets from multiple sources to a destination, ranging from simple private key transfers to advanced gas-optimized and signature-based patterns.

Strategy Selection Guide

Choose the appropriate strategy based on your requirements and infrastructure:

1. Legacy Strategy (Direct Transfer)

Best for: General use case with private keys.

• Pros: Works with any ERC20 token; simple logic.
• Cons: High gas cost (requires ETH on every source account); management of dust ETH.
• Mechanism: Admin funds source -> Source sends token.

2. Factory Strategy (CREATE2)

Best for: High-volume deposit addresses (e.g., exchanges).

• Pros: Lowest gas cost; clean address management; no private keys needed (just salt).
