(01) Overview
Zunia is a self-custody multi-chain wallet for the Cosmos ecosystem: hold, send and stake from a browser extension and a phone that share the same keys. No account, no token.
I founded Zunia Lab and lead a team of four developers and a community manager. I own the architecture, the security model and the release process, from plain-language transaction decoding to hardware wallet support.
