Executive Summary
High-level assessment and conclusions
A concise overview of the audit scope, core findings, and the key outcomes from the engagement.
The audit focused on assessing the security and functionality of Anza’s Token Wrap program, a key component designed to improve interoperability between token standards within the Solana ecosystem. The program allows users to wrap tokens into either SPL Token or SPL Token 2022 formats, ensuring seamless interaction across different token types. Conducted from September 25 to October 6, 2025, the audit evaluated new features introduced since the previous Runtime Verification review, including default confidential transfers, expanded token metadata support, metadata synchronization, and a standard interface for customizable token mints. The engagement aimed to validate the security, correctness, and reliability of these updates and confirm that the Token Wrap program continues to meet high standards for robustness and interoperability within the Solana network.
