The file is the module exactly as the page had it. WebAssembly does nothing on its own: it runs only when a script instantiates it. Labels describe what the module contains and are leads, not verdicts.
At a glance
- What it is
- Known library: dotLottie animation player.
- How it was built
- Written in Rust. wasm-bindgen connects it to the page's JavaScript.
- What it can do
- Its imports reach: page content. Judged from the names of its imports.
- Where we saw it
- On 6 public scans, 2026-10-02 to 2026-10-22.

How it was built
Written in Rust. wasm-bindgen connects it to the page's JavaScript.
- Language
- RustThe Rust compiler (rustc) left its name in the module.
- Connects to JavaScript
- wasm-bindgenRust's bridge to JavaScript. It writes glue code on both sides, so the module can call page functions such as fetch or the DOM, and the page can call the module.
- Rewritten after compiling
- walrusA library for rewriting compiled modules. wasm-bindgen runs it on every build, so it comes with wasm-bindgen and says nothing more about the module.
Read from text inside the module (its build metadata and paths the compiler left) and from its import and export names. Whoever builds a module can change or remove these, so treat them as hints. They say how a module was made, not what it does.
What it is made of
4 Rust crates from crates.io, with the versions it was built with:
Build tools and versions it names:
- walrus 0.23.3
- wasm-bindgen 0.2.100
Read from text the build left in the module: source paths, build metadata and .NET metadata. Whoever builds a module can change or remove it, so treat it as a hint.
Decompiled code
2,075 of 2,076 functions decompiled to C-like pseudocode; 72 more are imported from the page.
- 1 of 2,076 functions could not be decompiled.
Decompiled code is a reconstruction from the file, so names and types are often guesses. Query values in URLs are masked here; the downloaded file is unchanged.

Data segments
Each bar is one segment of the module's data: as wide as its size, as tall as its entropy. Bars above the dashed line are encrypted or compressed. 243 segments, 84.4 KiB in all. The chart shows 65: the first 64 and every encrypted or compressed one.
- Segment 34: 7,680 bytes at 7.55 bits per byte
- Segment 58: 5,275 bytes at 7.8 bits per byte
- Segment 127: 2,519 bytes at 7.8 bits per byte
Imports (72)
Can reach: dom.
Imports from wbg are wasm-bindgen glue. Each __wbg_… import calls one JavaScript function in the page, and its name says which (__wbg_fetch_… calls fetch). The __wbindgen_… imports are wasm-bindgen's own helpers for strings, errors and memory.

- unpkg.com loads it; the script is minified or bundled.
From public scans. A script loads a module when it fetches or compiles it.
Text it passes to the page
Fixed text the module hands to the page's JavaScript when it calls an import, read from the module file. Imports that reach the network, run code or change the page come first; web addresses are shown as their host.
