FAQs

PrimeOne is the next-generation prime broker for crypto trading. With a single account, clients can trade with any counterparty they choose. At its core, it is a breakthrough credit mechanism that transfers mark-to-market gains and losses in real time, ensuring safe and efficient trading between participants.

This innovation makes PrimeOne the only truly scalable credit solution – enabling rapid client onboarding without balance sheet exposure. It also delivers significant cost savings, operational efficiencies, and margin optimization, all backed by institutional-grade trading infrastructure and seamless post-trade net settlement.

PrimeOne allows clients to trade with each other based on margin deposits and a real-time exchange of variation margin (P&L).

• Each account is always updated to the latest mark-to-market balance with real, withdrawable funds (not just accounting entries).
• Settlement occurs via the real time exchange of USD stablecoins on the purpose-built PrimeOne blockchain.
• Variation margin transfers are executed automatically every minute, ensuring that by the start of each minute, all participants have zero credit exposure to each other.
• At 5pm NY time, PrimeOne generates net settlement instructions for each participant, summarizing token movements across all counterparties. These can be executed via third-party custodians or local self-custody (e.g., hardware wallets).

Clients are always fully secured by mandatory margin balances, protecting them in the event of sudden market moves.

PrimeOne provides all the benefits of a traditional prime broker – freedom to trade with whomever you want, whenever you want – but with key advantages:

• Faster: Clients can go live in days, not months.
• Cheaper: A reduced technology fee replaces significant PB fees.
• Safer: P&L is delivered in real time (not every 24+ hours).
• Balance sheet–free: PrimeOne does not rely on its own balance sheet, removing systemic credit risk during market stress.
• Integrated: Trading, credit, and settlement are unified in one platform.

With a rules-based credit platform and real-time blockchain settlement, PrimeOne represents the future of prime brokerage.

PrimeOne is fully API-enabled, supporting REST, WebSocket, and FIX connectivity for professional trading. An easy-to-use web interface is also available to:

• View credit, balances, and P&L
• Place and manage trades
• Run algorithms
• Manage daily settlement operations

• Markets tab: Low-latency aggregated order book showing transparent prices from all liquidity sources. Traders can enter orders and algorithms against one or multiple providers without needing separate accounts.
• Credit tab: Real-time display of open positions, available margin, P&L, and blotter data (both GUI and API trades).

Once your account opening documentation is complete, PrimeOne will provide funding instructions. Fiat deposits are available in your funding wallet within hours and stablecoin deposits are available within minutes. Fiat withdrawals are processed via standardized instructions and are typically completed the same day.

PrimeOne’s real-time credit management technology allows users to trade with any counterparty, using a range of execution methodologies. The platform connects participants to all integrated market makers and exchanges via streaming executable prices, as well as advanced tools such as algorithmic execution products.

With PrimeOne, onboarding is completed in days instead of months. From a single account, clients can immediately trade with any participant on the network and access as many liquidity providers as their strategy requires.

Currently, PrimeOne supports deliverable spot crypto. Additional products – both new product types and asset classes – will be introduced in the future.

• All contracts are initiated with the intention of physical delivery.
• Clients may roll positions forward via an integrated funding/lending mechanism.
• Daily net physical settlement occurs at 5pm NY time, with pre-prepared unsigned transactions available for execution via custodians or self-custody wallets.
