In November 2022, the crypto exchange FTX imploded in spectacular fashion, revealing a catastrophic failure in margin risk management. At the heart of the collapse was Alameda Research, a trading firm tightly linked to FTX through shared ownership and opaque operational boundaries.
The Margin Risk Breakdown
According to the Commodity Futures Trading Commission (CFTC), FTX and Alameda operated as a “common enterprise,” with Alameda granted special privileges that undermined the exchange’s risk protocols. These included:
- Unlimited Credit Line: Alameda was allowed to maintain an essentially unlimited line of credit on FTX, bypassing standard collateral requirements.
- Liquidation Exemption: Alameda was secretly exempted from FTX’s auto-liquidation protocols, meaning it could maintain leveraged positions that would have triggered liquidation for any other participant.
- Preferential Execution: Alameda received faster trade execution and other undisclosed advantages, distorting fair access and market integrity.
These exceptions were not disclosed to users or regulators. The CFTC found that customer assets—including fiat, Bitcoin, and Ether—were commingled and misappropriated by Alameda for proprietary trading and high-risk investments.
Regulatory Findings
In August 2024, the U.S. District Court for the Southern District of New York ordered FTX and Alameda to pay $12.7 billion in restitution and disgorgement to victims of the fraud. The court concluded that FTX violated the Commodity Exchange Act by making material misrepresentations about asset custody, segregation, and risk controls.
CFTC Chairman Rostin Behnam summarized the failure bluntly: “FTX used age-old tactics to create an illusion that it was a safe and secure place to access crypto markets. But the basic regulatory tools—like governance, customer protections, and surveillance—were simply not there.”
Arcitechtural Lessons and Design Principles
The FTX case underscores the existential risk posed by discretionary overrides and opaque privilege structures. When margin enforcement is subject to manual exceptions or insider influence, the integrity of an entire exchange can be compromised.
For developers and architects building matching engines, this is a call to action:
- Deterministic enforcement must be embedded at the protocol level.
- Auditability and reproducibility must be guaranteed through event sourcing and immutable state transitions.
- Fair access must be enforced algorithmically, not administratively.
Through the use of an event sourced ledger, additionally:
- Every state change is recorded as an append-only event.
- Guaranteed reproduction is supported through mechanisms such as cryptographic proofs.
- Full auditability and forensic traceability.
The Nekuti Solution
Nekuti’s Matching Engine is designed to address the systemic weaknesses exposed by the FTX collapse. Its architecture encourages deterministic behaviour and assists the elimination of discretionary overrides through algorithmic and protocol-level guarantees. Nekuti Matching Engine Solutions
Deterministic Margin Enforcement
All margin checks and liquidations are triggered by immutable state transitions. No user or admin can bypass enforcement logic. Compatible with smart contract–based thresholds when deployed on-chain.
Fairness
Trade execution priority is determined by transparent rules implemented by the engine. No preferential treatment—every participant is subject to the same rules.
Blockchain Compatibility
The Nekuti Matching Engine is designed to integrate seamlessly with blockchain environments, enabling exchanges to deploy the engine on-chain for enhanced transparency and trust. Some of the benefits of using a blockchain are:
- Smart Contract Integration: Enforcement logic can be encoded into smart contracts to ensure deterministic behaviour and protocol-level guarantees.
- Deterministic Execution: The engine’s behaviour is fully deterministic, making it suitable for consensus-driven environments.
- Immutable State Transitions: All changes are recorded as append-only events, aligning with blockchain immutability principles.
- Auditability: State changes are externally verifiable within blockchain environments, ensuring transparency and traceable records.
Together, these features make Nekuti a robust foundation for building exchanges that prioritize integrity, transparency, and user protection.
