R3E Network has published a JavaScript-based decompiler SDK for Neo N3 smart contracts, enabling developers to convert compiled NEF bytecode into human-readable code. Jimmy Liao, Neo core developer and R3E Network founder, 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 to Neo N3. Once integrated into neo3scan.com, the decompiler aims to automatically convert contract bytecode into readable code when users view contract pages on the explorer.

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, governance tools, and developer utilities. Automatic contract decompilation would extend that functionality, allowing users to inspect the logic of deployed contracts even when source code has not been published.
Contract decompilation is a common feature on mature blockchain explorers, helping developers and security researchers audit on-chain behavior and verify contract functionality independently.
