Prime Services Infrastructure

Membrane Labs' Prime Services Infrastructure provides institutional-grade digital asset prime brokerage capabilities including margin financing, custody integration, clearing, settlement, and unified account management across multiple custodians and venues. The platform centralizes post-trade operations with automated margining, collateral enforcement, and real-time exposure visibility.

Margin Financing & Lending

The Loan Management System centralizes digital asset loan servicing operations across borrowers, entities, assets, and custodians. Supports continuous interest accrual for fixed, floating, and open-term structures with custom day-count and compounding rules. Provides real-time LTV and exposure monitoring with automated margin call generation and enforcement. Handles principal disbursements and repayments, interest, fee, and adjustment transfers with multi-custodian routing.

Collateral Management & Cross-Margining

The Collateral Management Engine operationalizes margining, enforcement, and cross-custodian collateral tracking for institutional credit programs. Configure agreement-level rules across assets, entities, and custodians with LTV logic, haircut schedules, thresholds, and escalation paths. Tracks exposure, utilization, and LTVs while validating collateral health across multiple venues and custodians in real time. Generates automated margin calls with preconfigured routing logic and enforces collateral movements via integrated custody settlement.

Trade Clearing & Settlement

The Settlement Engine orchestrates cross-custodian and cross-chain settlement with defined outcomes, real-time confirmation, and full auditability. Routes principal, interest, fees, and collateral to defined accounts and sub-accounts while tracking confirmations across entities. Supports cross-chain settlement with on-chain validation and maintains complete auditable transaction history. End-to-end reconciliation matches expected vs. actual settled amounts and auto-flags breaks.

Unified Account Management

CustodyLink Network provides cross-custodian settlement infrastructure with real-time visibility and custody-verified state alignment for institutional post-trade workflows. Integrates multiple custodians (Anchorage Digital, BitGo, Fireblocks, Copper, Coinbase, Kraken, Zodia Custody, Ledger) and major exchanges (Binance, Bybit, Crypto.com, Deribit, Bitstamp, OKX, Gate.io) through one unified settlement layer. Normalizes balances and obligations into a unified operational dataset with deterministic settlement states. Supports automated netting cycles to reduce gross exposure and on-chain transaction volume.

Risk Management & Exposure Monitoring

The Risk Analysis Engine delivers continuous exposure monitoring, stress simulations, and scenario modeling across digital asset portfolios. Provides live VaR, expected shortfall, and downside thresholds with real-time LTV and utilization tied to custodian-verified balances. Runs historical and synthetic shock modeling with Monte Carlo simulations and correlation-driven shocks. Includes margin call forecasting under different volatility regimes with liquidity drawdown modeling.

Integration & Deployment

All modules integrate seamlessly to provide unified prime services infrastructure. Can be deployed as complete platform or individual modules. Integrates with internal risk, treasury, and accounting systems via API. Provides unified dashboard for operations teams with role-based access controls and approval workflows.
