Who Is Rafael Cosman? TrueUSD Co-Founder and Stablecoin Infrastructure Pioneer Explained

Rafael Cosman is the co-founder of TrueUSD (TUSD), one of the earliest fully collateralized U.S. dollar-backed stablecoins, launched by TrustToken (now Archblock). Through TrueUSD and the broader TrustToken ecosystem, Rafael Cosman helped pioneer transparent, regulated stablecoin infrastructure designed to bridge traditional finance and blockchain technology. His work reflects the growing importance of trusted digital dollars in decentralized finance (DeFi), payments, and tokenized assets.

Early Background and Career

Before co-founding TrustToken, Rafael Cosman worked as a machine learning engineer at Google Brain, where he focused on artificial intelligence and reinforcement learning. He also held engineering and research roles at Kernel and served as an Innovator in Residence at StartX. Cosman graduated from Stanford University with a bachelor’s degree in Computer Science.

Alongside his work in technology, Cosman co-founded StreetCode Academy, a nonprofit organization that provides technical education to underserved communities. His background in AI, distributed systems, and entrepreneurship laid the foundation for building blockchain-based financial infrastructure.

How Rafael Cosman Created TrueUSD

Rafael Cosman co-founded TrustToken in 2017 with the goal of bringing real-world assets onto the blockchain through legally compliant tokenization. The company’s first product was TrueUSD (TUSD), launched in 2018 as a fully collateralized stablecoin backed 1:1 by U.S. dollars held in third-party escrow accounts.

Unlike many early stablecoins, TrueUSD emphasized transparency through independent reserve attestations and legal protections for token holders. The project sought to reduce counterparty risk while providing a reliable digital dollar for exchanges, traders, and decentralized finance applications.

As stablecoin adoption expanded, TrueUSD became available across multiple blockchain networks and established itself as one of the leading fiat-backed stablecoins in the crypto ecosystem.

How TrueUSD Works

TrueUSD is a fiat-backed stablecoin designed to maintain a 1:1 peg with the U.S. dollar. Every TUSD token is backed by an equivalent amount of U.S. dollars held in regulated financial institutions, with reserve balances regularly verified by independent attestations.

Users can mint TUSD by depositing U.S. dollars through authorized partners and redeem tokens for fiat through the same process. The stablecoin operates across multiple blockchain networks, making it widely usable for payments, trading, lending, and decentralized finance. TUSD has also integrated on-chain Proof of Reserve technology to improve transparency.

Rafael Cosman’s Role at TrueUSD
