Could you build this?
No Wasmer SDK relies on Wasmer's WebAssembly runtime, WASI virtualization, and compiling complex runtimes like Python, Node.js, and Postgres into sandboxed Wasm bytecode. Virtualizing system calls and POSIX environments inside Wasm requires elite systems and compiler engineering.
What it would actually take: The technology requires a production WebAssembly compiler and runtime (written in Rust) with full WASI (WebAssembly System Interface) and virtual filesystem (memfs) implementations. It compiles full POSIX-compliant runtimes like CPython, Node.js, and PostgreSQL to WebAssembly using custom libc/WASI syscall shims and threading emulation for browsers (SharedArrayBuffer/Web Workers). Building this demands deep expertise in compiler toolchains (LLVM), systems virtualization, and WebAssembly internals.

Same idea, different domain
Nobody's really built a model & infra tool for Fintech yet.
