Integral launched PrimeOne on September 30, 2025, the first prime brokerage for crypto markets built around stablecoin-based credit, trading, and settlement.
The service operates on the Codex Layer-1 EVM blockchain and is live with institutional clients and liquidity providers, including Virtu Financial and Europa Partners. Integral provides technology services for currency markets to financial institutions, brokers, and payment firms globally.

PrimeOne allows clients to trade across crypto exchanges and market makers through a single account. The platform uses on-chain infrastructure where USD margin shifts between counterparties' wallets in real time rather than requiring pre-issued credit lines.

Trading limits adjust automatically based on participants' margin balances. The system reduces capital requirements and streamlines onboarding through one unified KYC/AML check, according to Integral.

The platform eliminates the need for clients to maintain multiple relationships across different trading venues. Real-time margin exchange aims to prevent cascading defaults among participants.
Integral was founded in 1993 and operates in foreign exchange and digital asset technology. The company has not disclosed the number of clients currently using PrimeOne or the transaction volumes processed since launch.

The Codex blockchain provides the infrastructure for the stablecoin-based settlement system. Integral has not specified which tokens the platform supports or whether it plans to expand beyond USD-pegged assets.

PrimeOne competes with traditional prime brokerages that serve crypto trading desks and institutional investors. The platform differentiates itself through its stablecoin-native architecture rather than fiat-based credit arrangements. 

The company has not announced pricing details or minimum account sizes for accessing the service. Integral indicated it will continue adding liquidity providers and trading venues to the platform.
