How Does Safeheron Tackle “What You See ≠ What You Sign” —— Anatomy of Bybit’s breach

The Bybit Incident: A Summary

On Feb 21, 2025, at 22:13 Singapore time, Bybit’s treasury team initiated a cold-to-warm wallet transfer using Safe{Wallet}’s multi-signature workflow. Although CEO Ben verified the destination address via Safe{Wallet}, during the final confirmation using a Ledger hardware wallet, the Ledger device only displayed contract interaction parameters and failed to show the complete transaction details. This vulnerability allowed attackers to exploit the process and successfully steal $1.4 billion in assets.

While investigations remain ongoing, two attack vectors are suspected:

• Compromised Safe{Wallet} infrastructure (spoofed UI displaying false addresses).
• Device-level hijacking (transaction address altered).

Safe{Wallet} has denied breaches, but the incident mirrors recent exploits like Radiant Capital’s $4.5M loss, underscoring systemic risks in institutional wallet design.

The Root Vulnerability: “What You See ≠ What You Sign”

The Bybit breach exemplifies the fatal gap between displayed intent and executed action — a flaw inherent to many wallet architectures:

A. Infrastructure Compromise

If attackers hijack a wallet’s UI/backend, users may unwittingly approve malicious transactions masked as legitimate.

B. Ecosystem Compatibility Issues

The ByBit breach highlights a critical flaw in ecosystem compatibility: even with secure devices like Ledger, the lack of seamless integration between systems can undermine security. In this case:

• Safe’s UI Was Compromised: Attackers manipulated the displayed destination address, making it appear legitimate.

• Ledger’s Offline Verification Fell Short: As the final line of defense, Ledger failed to effectively implement "what you see is what you sign" due to poor compatibility with Safe’s UI. It only displayed contract interaction parameters and failed to show the complete transaction details.

Smart contract based solutions like Safe{Wallet} excel at key fragmentation but may not fully address transaction integrity verification, highlighting the need for enhanced security measures tailored to institutional use cases. This incident underscores the importance of adopting robust multi-layered solutions to safeguard against sophisticated exploits in high-stakes environments.

The Solution: How Safeheron Ensures "What You See = What You Sign"

Safeheron’s military-grade security architecture — MPC (Secure Multi-Party Computation) + TEE (Trusted Execution Environment) + Policy Engine — is engineered to prevent such attacks at every layer:

Layer 1: Policy Engine Block Non-whitelisted Transfers at the Pre-Approval Stage

• Transfers to Whitelisted Addresses: Safeheron’s Policy Engine enables institutions to restrict transfers exclusively to pre-authorized addresses, ensuring non-whitelisted transactions are automatically blocked before they even reach the approval stage.

• Threshold Rules: Multi-tiered approvals, time locks, and volume caps mitigate human error or insider threats.
  

Layer 2: TEE & Multi-Signature Protect Whitelist Integrity

With safeheron, whitelisted addresses can only be added or modified through multi-party consensus, removing single points of failure. Real-time tampering detection within TEE triggers instant alerts if unauthorized changes are attempted, ensuring the whitelist remains secure.

Layer 3: TEE Guarantees "What You See Is What You Sign"

Every transaction is hashed, signed, and validated within Intel SGX-secured TEE. Tamper-proof attestation reports ensure that the UI-displayed data (recipient, amount) exactly matches the on-chain execution, eliminating discrepancies between intent and action.

Conclusion

Safeheron’s architecture would:
✅ Block non-whitelisted transfers at the policy layer.
✅ Detect and reject UI/backend spoofing via TEE integrity checks.
✅ Require collusion-resistant consensus for whitelist changes.

Institutional Wallet Security: Why Architecture Dictates Survival

The Bybit incident is not an anomaly but a referendum on wallet design:

Safeheron redefines institutional security with institutional-grade safeguards:

• No Single Failure Layer: MPC key shards;TEE ensures what you see is what you sign; policies enforce rules.
• Zero Blind Spots: Every transaction is cryptographically tied to human-verified intent.

By integrating advanced cryptographic techniques and decentralized governance, Safeheron provides a comprehensive security framework that addresses both external and internal threats, setting a new standard for institutional asset protection.
