Source Map

GenerateProduce a .map file linking output back to original source

Seed

ChainVM Engine v1

Compiles JS into an encrypted, self-defending virtual machine. The original source is transformed, fragmented, and destroyed. Each fragment uses a unique derived key from a one-directional chain — no single capture point yields the original code.

One-shot key chain — fragment keys derive from each other; re-decryption is impossible after execution
Ephemeral strings — decrypted on-demand per access, never cached
Polymorphic identifiers — all user names replaced with random hex IDs
Opaque number encoding — integer literals replaced with arithmetic expressions
Anti-debug suite — timing traps, console poisoning, DevTools detection
Proxy tamper shield — detects introspection of the VM scope object

Protection Layers

Anti-Debug SuiteTiming trap (self-destructs on step-through), console guard, regex DevTools probe

Identifier ScrambleRename all user-defined variables & functions to random 8-char hex IDs

Number EncodingSplit integer literals into opaque arithmetic expressions

Proxy Scope ShieldWrap VM execution scope in a Proxy that detects property enumeration

Dead Code InjectionInject unreachable junk functions and branches throughout the output

Fragmentation

Fragment Count8

More fragments = harder to reverse, larger output. Each fragment encrypted with a unique derived key.

VM Seed

Same seed = same identifier mapping. Useful for incremental builds.

ChainVM works on most practical JS. Code relying on arguments.callee, non-strict with, or live hoisting across module boundaries may need refactoring first.
