Audit Checklist

Security audit checklist for Selendra smart contracts.

Code Quality

• Compiles without warnings
• Linter passing
• Documentation complete
• Dependencies audited and up to date

Contract Design

Architecture

• Purpose clearly defined
• Upgrade mechanism planned
• Emergency mechanisms implemented
• Gas costs optimized

Access Control

• Role-based access implemented
• Owner/admin functions protected
• Multi-sig if required
• Pausable for critical functions

Implementation

Input Validation

• All external inputs validated
• Zero addresses handled
• Numeric ranges checked
• Array bounds verified

State Management

• State changes atomic
• Race conditions prevented
• Reentrancy protection
• Gas optimization applied

Error Handling

• Clear require messages
• Custom errors defined
• Failure modes documented

Events

• Important changes logged
• Parameters indexed
• Sufficient detail included

Security Patterns

Reentrancy

• Checks-Effects-Interactions pattern
• OR ReentrancyGuard modifier
• External calls after state updates

Integer Safety

• Solidity 0.8+ (built-in protection)
• Edge cases tested

Timing

• block.timestamp used appropriately
• Randomness not predictable

External Calls

• Return values checked
• Gas limits set
• Delegatecall verified

Testing

Coverage

• 100% function coverage
• All code paths tested
• Edge cases covered
• Error conditions tested

Security Tests

• Reentrancy attacks
• Overflow attempts
• Access control bypasses
• Front-running scenarios
• DoS prevention

Deployment

Network

• Chain ID verified (1961)
• RPC endpoints secure
• HTTPS enforced

Key Management

• Private keys secure
• Hardware wallets used
• Multi-sig for critical ops

Operations

• Time delays for sensitive functions
• Emergency pause/resume
• Monitoring configured

Verification

Reviews

• Security expert review
• Peer review completed
• Third-party audit

Tools

• Fuzzing (Echidna, Mythril)
• Compiler warnings addressed

Post-Audit

Remediation

• Critical issues fixed
• Medium issues addressed
• Fixes verified
• Regression testing done

Monitoring

• On-chain monitoring
• Security alerting
