Overview

Pulsar is a straightforward tool that uses taint-guided fuzzing to discover account, and instruction parameter layouts in Solana closed-source programs.

Often integrated with Rewind to enhance decompilation capabilities by providing discovered interface information to decompilation output.

Why Pulsar?

Understanding closed-source Solana programs requires knowledge of their instruction and account data layouts, which typically involves manual reverse engineering work.

Pulsar automates this process through taint-guided fuzzing, quickly identifying instruction parameters and account structures. This information is particularly useful when integrated with Rewind, providing context that improves decompilation accuracy.

While it doesn't replace conventional security analysis, Pulsar serves as a practical starting point for understanding program interfaces without documentation.
