Sharing JavaScript is dangerous when you cannot track who wrote the code or trace trust through its dependencies; that's when you need iframes and origins.

With Seed’s traceability and web of trust, we can bring provenance to executable code.

Every piece of code is signed. Every dependency is attributable. You decide whose code you trust, and you can trace that trust through the dependency graph.

No WASM. No sandboxing magic.

Run code from people you trust.
