We actively support the following versions of the Solana Escrow Program:

The security of our users' funds is our highest priority. If you discover a security vulnerability, please report it responsibly.

For critical security vulnerabilities that could lead to loss of funds or compromise user assets, please:

1. DO NOT open a public GitHub issue
2. DO NOT disclose the vulnerability publicly until we have addressed it
3. Send an email to [security@0x-professor.dev] with:
   • A detailed description of the vulnerability
   • Steps to reproduce the issue
   • Potential impact assessment
   • Your contact information for follow-up

• Initial Response: Within 24 hours
• Status Update: Within 72 hours
• Resolution Target: Within 30 days (depending on complexity)

1. Acknowledgment: We'll acknowledge receipt of your report within 24 hours
2. Investigation: Our team will investigate and validate the reported vulnerability
3. Development: We'll develop and test a fix for confirmed vulnerabilities
4. Disclosure: After the fix is deployed, we'll coordinate public disclosure
5. Recognition: We'll publicly acknowledge your contribution (if desired)

• Audit Before Use: Always audit smart contracts before interacting with them
• Test on Devnet: Test all interactions on Solana devnet before using mainnet
• Verify Program ID: Always verify you're interacting with the correct program ID
• Check Account Ownership: Ensure all accounts are owned by expected programs
• Monitor Transactions: Review all transaction details before signing

• Code Reviews: All code changes must undergo thorough peer review
• Automated Testing: Maintain comprehensive test coverage (>90%)
• Dependency Updates: Keep all dependencies up to date
• Static Analysis: Use tools like Clippy and other security linters
• Formal Verification: Consider formal verification for critical components

// Always validate account ownership
if account.owner != expected_program_id {
    return Err(ProgramError::IncorrectProgramId);
}

// Verify signer requirements
if !account.is_signer {
    return Err(ProgramError::MissingRequiredSignature);
}

// Ensure accounts are rent-exempt
if !rent.is_exempt(account.lamports(), account.data_len()) {
    return Err(EscrowError::NotRentExempt.into());
}

// Use checked arithmetic operations
let result = amount
    .checked_add(fee)
    .ok_or(ProgramError::ArithmeticOverflow)?;

// Always verify PDA derivation
let (expected_pda, bump) = Pubkey::find_program_address(&[b"escrow"], program_id);
if expected_pda != *pda_account.key {
    return Err(ProgramError::InvalidSeeds);
}

1. Signer Verification: All critical operations require proper signatures
2. Account Ownership Validation: Strict validation of account ownership
3. Rent Exemption Checks: Prevents account deallocation attacks
4. Amount Validation: Prevents integer overflow and underflow
5. Initialization Guards: Prevents double-initialization attacks
6. PDA Authority: Secure token custody using Program Derived Addresses

• Internal Audits: Conducted by the development team
• Peer Reviews: All code changes reviewed by multiple developers
• Community Testing: Open source code allows community auditing

We plan to conduct professional security audits before mainnet deployment.

• GitHub Releases: Critical security updates will be published as releases
• README Updates: Important security information will be updated in README
• Community Channels: Updates shared via GitHub Discussions

1. Immediate Fixes: Critical vulnerabilities receive immediate patches
2. Version Bumps: Security fixes trigger version updates
3. Migration Guides: Breaking changes include migration documentation
4. Backward Compatibility: We maintain backward compatibility when possible

We are considering implementing a bug bounty program. Details will be announced if/when the program launches.

• In Scope:

  • Smart contract vulnerabilities
  • Logic errors leading to fund loss
  • Access control bypasses
  • Integer overflow/underflow issues

• Out of Scope:

  • Client-side vulnerabilities
  • Social engineering attacks
  • Issues in third-party dependencies
  • Denial of service attacks

1. Immediate Assessment: Evaluate the severity and impact
2. Temporary Mitigation: Implement temporary fixes if possible
3. Stakeholder Notification: Inform key stakeholders and users
4. Patch Development: Develop and test comprehensive fixes
5. Coordinated Deployment: Deploy fixes with minimal disruption

• Public Advisory: Issue public security advisories for all vulnerabilities
• User Notifications: Direct notifications for users of affected versions
• Developer Updates: Technical details shared with development community

• OWASP: Following OWASP smart contract security guidelines
• Solana Best Practices: Adhering to Solana security recommendations
• Industry Standards: Following blockchain security best practices

• Quarterly Reviews: Regular security posture assessments
• Dependency Audits: Regular review of all dependencies
• Code Quality Gates: Automated security checks in CI/CD pipeline

• Security Email: security@0x-professor.dev
• General Contact: GitHub Issues
• Emergency Contact: Create a critical issue on GitHub with [SECURITY] prefix

We thank the security research community for their efforts in keeping the ecosystem safe. Responsible disclosure helps protect all users.
