Institutional Security Framework
Cube uses distributed key generation and threshold signing to remove the single point of failure that defines legacy custodial storage. Control is segmented, policy aware, and continuously monitored.
01
Non-Custodial MPC Vault
Distributed key generation splits private key material among you, Cube Exchange, and independent Guardians using a two-of-three signature threshold. No single party ever holds a complete private key.
02
Guardian Network
An independent council verifies transactions and can facilitate direct withdrawals from your MPC vault if settlement is unavailable for more than 48 hours.
03
Segregated User Funds
Your assets are held in your own MPC wallet, never co-mingled with other users' funds or Cube's operating capital. This structurally eliminates the exchange insolvency and bank-run risks that have affected custodial platforms.
04
On-Chain Settlement
Matched trades settle on-chain, producing verifiable, tamper-resistant transaction records. Settlement transparency means you don't have to trust internal ledgers: you can verify activity directly on the blockchain.
05
Key Recovery
If your key share is lost or compromised, Cube's identity verification process and Guardian coordination can generate new key material and migrate assets to a fresh MPC wallet, without exposing funds during the recovery window.
Always on
24/7 Threat Detection
Transaction screening, wallet telemetry, and system integrity checks run continuously across Cube Exchange's matching engine and settlement layer to flag abnormal activity before it propagates.
Third-party verified
Independent Security Audits
Cube Exchange undergoes third-party security assessments, including code review and penetration testing, to identify vulnerabilities before they become operational risk.

Bug Bounty
Security researchers can report vulnerabilities through Cube's active bug bounty program, with rewards up to $10,000 for qualifying disclosures.
How Cube Exchange Secures Your Crypto
MPC wallets vs. single-key custody
Conventional exchanges store your assets behind a single private key they control. Cube Exchange replaces that model with a non-custodial MPC vault: during account creation, a distributed key generation splits signing authority among you, Cube, and an independent Guardian network using a two-of-three threshold. No single party ever holds the complete key, so authorization requires collaborative computation; not blind trust in one entity.
Self-custody that scales for institutions
Institutional-grade crypto trading demands operational control, disaster recovery, and clear escalation paths. Cube's non-custodial architecture keeps you as the ultimate authority over asset movement.
Security as architecture, not afterthought
Cube treats exchange security as a design constraint from day one: segregated user funds that are never co-mingled, threshold-signed transaction authorization, least-privilege access controls, and independent third-party security audits. Recoverability and transparent settlement are built into the operating model; not appended as marketing claims.
