Hi HN,

I built MephistoVault to scratch an itch: I wanted a way to send files securely between two browsers without them ever touching a middleman server.

It purely relies on WebRTC data channels for direct P2P connection and E2E encryption.

Tech stack: React, TypeScript, and WebRTC. There is no backend storage involved. Code: https://github.com/jokallame350-lang/mephistovaultt

I'd love your technical feedback—especially around NAT traversal edge cases, reliability strategies for larger files via chunking, or general UI thoughts.
