Affected Analytics Platforms: Major analytics platforms like DeFiLlama, Alium, and Blockworks are identified as using flawed methodologies that do not account for Polymarket's unique transaction structure, highlighting a broader challenge in DeFi analytics.
Call for Improved Methodologies: The incident emphasizes the need for analytics platforms to adopt protocol-specific accounting methods and for investors to verify volume metrics across multiple sources to ensure accurate data interpretation.
