TAC implements a comprehensive security framework with multiple layers of protection, professional audits, and continuous monitoring to ensure the safety of hybrid dApps and user assets.

​
Security Audits

Halborn Audit (EVM)

EVM Client Security Comprehensive audit of TAC’s EVM implementation by Halborn, covering blockchain security and client vulnerabilities.

Trail of Bits Audit (TON Adapter)

Cross-Chain Infrastructure Professional audit of the TON Adapter system by Trail of Bits, ensuring secure cross-chain messaging and consensus.

​
Multi-Layer Security Architecture

TAC’s security model operates across multiple layers to provide comprehensive protection for users and applications.

​
EVM Layer Security

Modern EVM Implementation: TAC EVM is based on the Cancun upgrade, incorporating the latest Ethereum security improvements and optimizations.Proven Technology: Built on battle-tested EVM specifications with all security features and protections of modern Ethereum networks.Standard Compliance: Full compatibility with Ethereum security models ensures familiar security guarantees for developers.
TAC Token Security: Network consensus secured by delegated Proof of Stake using $TAC tokens as the staking mechanism.Validator Incentives: Economic incentives align validator behavior with network security through staking rewards and slashing penalties.Distributed Validation: Multiple independent validators secure the network through distributed consensus mechanisms.
Enhanced Economic Security: Integration with Babylon protocol adds Bitcoin’s economic security to TAC’s consensus layer.Bitcoin Staking: Bitcoin holders can stake their BTC to provide additional economic security for TAC network operations.Dual Security Model: Combines dPoS consensus with Bitcoin’s proven security model for enhanced protection.

​
TON Adapter Security

The TON Adapter implements distributed architecture with multiple validation layers:
Current Network Status: The sequencer network is currently distributed but not decentralized. Full decentralization is on the roadmap as the network matures.
  • Distributed Architecture
  • Consensus Protection
Current State: TON Adapter operates with distributed sequencer groups providing redundancy and security validation.Multiple Validators: Multiple independent sequencer groups validate cross-chain transactions through consensus mechanisms.Future Decentralization: Architecture designed for progressive decentralization as the network matures.

​
Professional Security Auditing

TAC undergoes comprehensive security audits by industry-leading firms to ensure the highest security standards.

​
Completed Audits

Halborn Audit (EVM)

EVM Client Security Comprehensive audit of TAC’s EVM implementation by Halborn, covering blockchain security and client vulnerabilities.

Trail of Bits Audit (TON Adapter)

Cross-Chain Infrastructure Professional audit of the TON Adapter system by Trail of Bits, ensuring secure cross-chain messaging and consensus.

​
Additional Security Reviews

Quantstamp (Proxy Apps): Smart contract audits for proxy applications ensuring secure cross-chain contract interactions and asset management. Ongoing Reviews: Regular security assessments and code reviews as the protocol evolves and new features are added.

​
Continuous Security Monitoring

TAC implements 24/7 security monitoring and incident response capabilities to detect and respond to potential threats.

​
Real-Time Threat Detection

24/7 Security Monitoring: Hypernative provides continuous monitoring of TAC networks, detecting potential exploits and anomalous behavior.Mempool-Level Detection: Advanced monitoring capabilities detect suspicious transactions at the mempool level before they’re executed.Real-Time Alerts: Immediate notifications for potential security threats enable rapid response and mitigation.
24/7 Security Operations: Fully dedicated Security Operations Center (SOC) team monitoring TAC infrastructure around the clock.Incident Response: Trained security professionals ready to respond to any security incidents or threats.Proactive Monitoring: Continuous analysis of network activity and security metrics to identify potential issues before they become problems.

​
Security Certifications

Industry Standards: TAC maintains compliance with industry security standards and best practices for blockchain networks. Regular Assessments: Ongoing security assessments ensure continued compliance with evolving security requirements. Documentation: Comprehensive security documentation and incident response procedures maintain operational readiness.

​
Future Security Enhancements

TAC has planned significant security upgrades that will provide additional layers of protection and decentralization.

​
Babylon Bitcoin Restaking Integration

TAC plans integration with Babylon’s Bitcoin restaking protocol to add massive economic security:
Leveraging Bitcoin’s Economic Strength:
  • Bitcoin holders delegate BTC stakes to Babylon validators
  • Validators cryptographically verify TAC EVM blocks and Merkle roots
  • Self-custodial delegation maintains decentralization without custody risk
  • Exponentially increases attack costs through Bitcoin’s security budget
Economic Penalties for Malicious Behavior:
  • Validators providing conflicting signatures face automatic slashing
  • Double-signing detection through Babylon protocol mechanisms
  • Direct economic penalties via Bitcoin blockchain enforcement
  • Makes attacks economically irrational at Bitcoin-scale security

​
FROST Consensus Upgrade

Planned migration to FROST-Ed25519 threshold signatures with Distributed Key Generation (DKG):
  • Threshold Security
  • Distributed Key Generation
  • Proactive Security
Enhanced Cryptographic Security:
  • Threshold signature creation requires t+1 out of n participants
  • Attackers controlling up to t participants cannot forge signatures
  • Ed25519 compatibility with existing verification systems
  • Round-optimized design minimizes communication overhead

​
Community Security Programs

TAC will launch comprehensive community-driven security programs following mainnet deployment.

​
Upcoming Programs

  • Bug Bounty Program
  • Audit Competitions
Reward Security Research: Comprehensive bug bounty program rewarding security researchers for discovering vulnerabilities.Tiered Rewards: Structured reward system based on severity and impact of discovered issues.Responsible Disclosure: Clear processes for responsible vulnerability disclosure and coordinated fixes.
Launch Timeline: Both bug bounty programs and audit competitions will begin shortly after mainnet launch, providing ongoing community-driven security validation.

​
Security Best Practices

For developers building on TAC, following security best practices ensures application and user safety:

​
Development Guidelines

Smart Contract Security: Follow established smart contract security patterns and undergo professional audits for production applications. Cross-Chain Considerations: Understand the unique security considerations of cross-chain operations and implement appropriate safeguards. Testing Requirements: Comprehensive testing including security-focused test scenarios and edge case validation.

​
Operational Security

Key Management: Implement secure key management practices for production deployments and user funds. Monitoring Integration: Integrate with TAC’s monitoring systems and implement application-specific security monitoring. Incident Response: Develop incident response procedures for potential security issues in your applications.

​
Transparency and Communication

TAC maintains transparency in security matters while protecting sensitive operational details: Public Audits: Audit reports are made publicly available for community review and verification. Security Updates: Regular communication about security improvements, patches, and best practices. Community Engagement: Active engagement with the security community for ongoing feedback and improvement.
