Non-Custodial Prime Brokerage
Non-custodial prime brokerage represents a new paradigm in institutional digital asset trading that enables professional traders and institutions to access trading services, leverage, and cross-venue liquidity while maintaining direct control of their assets. Unlike traditional prime brokers who hold client assets, non-custodial models use smart contracts and decentralized protocols to facilitate trading services without taking custody.
Core components of non-custodial prime brokerage
Non-custodial prime brokerage services combine several key technological and operational elements to deliver institutional-grade trading capabilities:
Smart contract-based collateral management
Rather than depositing assets with a broker, traders lock collateral in smart contracts that automatically manage positions and risk. This approach provides:
- Transparent collateral verification
- Automated margin calls
- Self-executing liquidation procedures
- Real-time position monitoring
Cross-venue liquidity aggregation
Non-custodial prime brokers aggregate liquidity from multiple sources:
- Decentralized Finance (DeFi) protocols
- Centralized exchanges via bridge protocols
- Cross-Chain Liquidity Aggregation services
This creates deeper liquidity pools while maintaining asset security through atomic settlement mechanisms.
Next generation time-series database
QuestDB is an open-source time-series database optimized for market and heavy industry data. Built from scratch in Java and C++, it offers high-throughput ingestion and fast SQL queries with time-series extensions.
Risk management and margin systems
Automated margin calculation
Non-custodial systems employ sophisticated risk models that calculate margin requirements in real-time:
- Position-level risk assessment
- Cross-asset margin netting
- Real-time collateral valuation
- Automated margin calls

Smart contract-based liquidation processes provide transparency and predictability:
- Predetermined liquidation thresholds
- Automated execution
- Waterfall liquidation procedures
