Reconstructing Penal Accountability in Crypto Asset Fraud: A Two-Dimensional Matrix Analysis of Digital Financial Crimes

Abstract

This study investigates the legal protection framework and penal accountability mechanisms for retail investors in crypto-assets. A Two-Dimensional Fraud Matrix was employed to map digital economic crimes along the spectrum of service centralization and dominant operational vectors. The proliferation of decentralized financial assets introduces sophisticated fraud typologies transcending conventional market volatility, encompassing smart contract exploitation, deceptive tokenomics, and orchestrated liquidity drains. Recently enacted Law Number 4 of 2023 concerning Financial Sector Development and Strengthening requires a critical evaluation of existing investor protection mechanisms against these complex vulnerabilities. With a normative legal research design, this study evaluates the structural alignment between positive legal norms and empirical risks across the digital asset ecosystem. The findings demonstrate that vulnerabilities categorize into CeFi-Technical, CeFi-Social, DeFi-Technical, and DeFi-Social quadrants. Existing statutory provisions align strongly with CeFi-Technical risks through traditional administrative compliance. Significant penal accountability gaps remain in addressing DeFi-Technical exploitation and DeFi-Social governance manipulation, where perpetrators exploit pseudonymous structures. Dismantling this structural impunity requires a shift from rigid entity-based administrative supervision to an adaptive penal policy. This reconstructive approach requires targeting the natural or legal persons exercising factual control over decentralized protocols by utilizing cyber law instruments and advanced digital forensics to ensure comprehensive market integrity and substantive justice.
