Codex powers Integral’s launch of PrimeOne, the world’s first stablecoin-based Crypto Prime Broker

PALO ALTO, September 30, 2025 - Codex, the high-performance Layer-1 EVM blockchain designed for institutional finance, today announced its role as the foundational infrastructure behind PrimeOne, the next-generation prime brokerage service launched by Integral. PrimeOne is the world’s first stablecoin-based prime broker for cryptocurrency markets, delivering credit, trading, and net settlement in a single integrated service.

Built entirely on Codex, PrimeOne leverages the protocol’s ultra-low-latency architecture and trustless settlement capabilities to introduce a new standard for capital efficiency and counterparty risk management in digital assets.

Through Codex, PrimeOne enables:

Stablecoin-based Credit & Margin Movement — Margin flows between market participants are settled in real time on-chain, eliminating bilateral credit risk.
Unified Market Access — One account, one wallet, and one KYC check allow traders to seamlessly access liquidity from all major exchanges and market makers.
On-Chain Settlement with Asset Control — Participants retain custody of their assets, while Codex enforces net settlement at scale.

“PrimeOne demonstrates how Codex can unlock a new generation of institutional services in digital assets,” said Masato Kikuchi, Managing Director of Codex Labs. “By embedding trustless credit and net settlement directly into the protocol, Codex enables brokers, banks, and fintechs to launch products that were not possible on legacy infrastructure.”

Integral, a global leader in FX and digital asset technology, is the first major partner to leverage Codex for institutional-grade prime brokerage. PrimeOne is already live with customers and liquidity providers, including leading global market makers.

“Codex’s performance and financial-market design made it the natural foundation for PrimeOne,” said Harpal Sandhu, CEO of Integral. “Together, we’ve delivered the first prime broker that combines institutional-grade trading technology with the transparency and risk management benefits of blockchain settlement.”

Codex continues to expand its ecosystem of partners across trading, custody, and DeFi infrastructure, making it the blockchain of choice for institutional finance.
