Spearbit - stBTC Security Review Final.pdf

pdf

Audit Overview

Auditor: Sigma Prime & Spearbit Date: May 2025 Focus: Bitcoin staking contract security analysis Repository: ControlCplusControlV/stBTC Commit: 3d22855

Scope

The stBTC audit focused on the Bitcoin staking infrastructure, examining:

• ERC4626 Vault Implementation: Standard compliance and security

• Staking Mechanisms: Token deposit and withdrawal security

• Reward Distribution: Fair and secure reward calculation

• Inflation Attack Prevention: Protection against vault manipulation

Methodology

• Standard Compliance: Verification of ERC4626 implementation

• Economic Security: Analysis of tokenomics and incentive structures

• Attack Vector Analysis: Focus on known vault vulnerabilities

• Integration Testing: Compatibility with Botanix ecosystem

Risk Assessment

Overall Security Posture

• Implementation Quality: High-quality implementation based on industry standards

• Attack Resistance: Strong resistance to common vault attacks

• Economic Security: Sound tokenomics with low exploitation risk

Identified Risks

• Theoretical Inflation Attacks: Very low probability, high complexity scenarios

• Economic Conditions: Dependency on specific market and timing conditions

• Multi-victim Scenarios: Requires coordination of multiple factors

Risk Mitigation

• Design Choices: Intentional risk acceptance based on low probability

• Monitoring: Potential for enhanced monitoring systems

• Community Oversight: Transparent operation and community validation

Scope

The audit focused on the Minting contract, a crucial component of Botanix's Layer 2 solution for Bitcoin that leverages the EVM as a foundational superstructure.

Repository: https://github.com/botanix-labs/Macbeth Commit: bac1da04873b378d9a195e897fb92c75412a5f72 Platform: Botanix EVM Language: Solidity

Methodology

The security assessment covered:

• Manual code review focusing on business logic implementation

• Internal contract interactions verification

• Known Solidity anti-patterns and attack vectors identification

• Automated testing using industry-standard tools:

  • Mythril

  • Slither

  • Surya

  • Aderyn

Key Areas Examined

• Access Control: Function-level permission verification

• Input Validation: Parameter sanitization and bounds checking

• Reentrancy Protection: Guards against recursive call attacks

• Integer Operations: Overflow/underflow prevention

• Gas Optimization: Efficient resource usage analysis
