R3E Network has published a JavaScript-based decompiler SDK for Neo N3 smart contracts, which allows developers to convert compiled NEF bytecode into human-readable code. Jimmy Liao, core developer of Neo and founder of R3E Network, announced the release on March 19, with plans to integrate the tool into the neo3scan.com blockchain explorer.
The SDK, published as @r3e/neo-decompiler-js on npm, decompiles Neo Executable Format (NEF) files – the compiled executable format used by smart contracts deployed on Neo N3. Once integrated into neo3scan.com, the decompiler aims to automatically convert contract bytecode into readable code when users view contract pages in the explorer.
Contract transparency on neo3scan.com
The decompiler integration builds on capabilities already present in neo3scan.com, R3E Network’s Neo N3 explorer that launched in late February with built-in script decompilation for transaction details, management tools and developer tools. Automatic decompilation of contracts would extend that functionality, allowing users to inspect the logic of deployed contracts even if the source code has not yet been published.
Contract decompilation is a common feature of mature blockchain explorers, allowing developers and security researchers to monitor on-chain behavior and independently verify contract functionality.
