Hetu, a pioneer in decentralized science (DeSci) and financial infrastructure, has unveiled Hetu 3.0, an Ethereum-based AI-Native Monetary Stack that transforms verified intelligence into programmable capital. This release, announced on October 30, 2025, introduces a tri-layered architecture designed to bridge crypto liquidity with the AI economy, creating what Hetu calls Deep Intelligence Money.
The foundation of Hetu 3.0 is $HETU, a fair-launched, deflationary base asset with a fixed supply of 21 million, serving as the anchor for liquidity and credit across the intelligence network. Flowing through the system is $AIUSD, a zero-fee stablecoin with millisecond settlement, backed by AI infrastructure revenue and offering yields of 8–12% for human and agent-level payments. Circulating between them is $FLUX, a real-time audit and reward layer powered by Proof of Causal Work (PoCW), which encodes proof, credit, and reputation into a unified on-chain cashflow financing standard.
Together, these tokens form a closed, auditable loop: verified work becomes $FLUX credit, settles through $AIUSD, and consolidates into $HETU's long-term value base. The system leverages Ethereum's liquidity via standards like EIP-8004, which enables verifiable agent identity and agent-to-agent settlement, and X402, which channels ETH and stablecoin liquidity into productive AI yield. According to Jialin Li, Co-Founder of Hetu Protocol, "By combining an EVM-compatible causal DAG with Proof of Causal Work, Hetu 3.0 bridges Ethereum liquidity with the AI economy — enabling autonomous agents to verify output, transact instantly, and finance future work."
Technically, Hetu 3.0 runs on an EVM-compatible causal-DAG ledger capable of 210,000 TPS, 400 ms finality, and 1 ms real-time audits across over 1,000 AI markets. It aims to redefine money by shifting from scarcity to abundance, where value derives from verified cognition and understanding, supported by mechanisms like Proof of Semantic Alignment (PoSA). This upgrade marks the emergence of a new monetary order where intelligence itself issues currency, fostering a self-verifying, self-financing ecosystem.
