Client Overview Pantos

Pantos, a pioneering multi-blockchain token system from Pantos GmbH, aims to create a secure, interoperable environment for seamless asset transfers across various blockchain networks. Developed to overcome interoperability challenges, Pantos supports cross-chain functionality, allowing users to transfer tokens and assets between blockchains with transparency, security, and efficiency​​.

To enhance its protocol security, Pantos engaged Softstack for an extensive security assessment of its Validator and Service Nodes and on-chain components. This audit examined vulnerabilities and recommended improvements, fortifying the infrastructure that underpins Pantos’ multi-blockchain ecosystem.

Project Scope

Validator and Service Node Audit

Pantos’ Validator Node validates cross-chain transfers, while the Service Node initiates these transfers on behalf of users. These nodes communicate via the PantosHub contract on the source blockchain, where each node registers itself to be discoverable by clients​.

The audit scope included:

  1. Authentication and Authorization Mechanisms – ensuring only authorized users can access APIs and validate transfers.
  2. Secure Key Handling – verifying that keys are securely encrypted and access is controlled.
  3. Comprehensive Logging and Monitoring – implementing alerts for suspicious activities.
  4. Secure Coding Standards – inspecting code quality, adherence to best practices, and eliminating common and unknown vulnerabilities.



Smart Contract Audit

The audit also covered Pantos’ on-chain components for Ethereum and EVM compatible blockchains. Key areas assessed were:

  1. Secure Coding Standards – inspecting code quality, adherence to best practices, and eliminating common and unknown vulnerabilities.
  2. Efficient Gas Usage – minimizing costs by optimizing code.
  3. Data Integrity – ensuring accurate state changes.
Methodology

Softstack employed a rigorous security evaluation process:

  1. Code Review: A line-by-line analysis identified potential vulnerabilities and verified adherence to specifications.
  2. Testing: Automated testing, symbolic execution, and best practices reviews were conducted to assess vulnerability coverage and code efficiency.
  3. Recommendations: Actionable suggestions were provided for resolving identified vulnerabilities​​.
Recommendations & Outcomes

Softstack’s audit concluded with a set of recommendations to further strengthen Pantos’ infrastructure. By addressing these, Pantos can ensure:

  1. Enhanced Security: Improved error handling, concurrency management, and the addition of slashing mechanisms reinforce Pantos’ defenses against potential exploits.
  2. Robust Infrastructure: Consistent best practices across the codebase ensure sustainable and resilient functionality.
  3. Operational Efficiency: Optimized gas usage and reduced risk of resource-intensive operations benefit Pantos’ scalability and cost-efficiency​​​.
