Accounts on any chain and platform, from a passkey.
mera is a TypeScript library for building passkey accounts. It gives applications authenticator-bound entropy and signing sessions that zero their keys when ended, while leaving account derivation, recovery, storage, and product flows under application control.
Developers can use mera to:
- create new accounts from a passkey without adding smart-account contracts or a custody service;
- protect an existing recovery phrase, private key, or other secret with a passkey;
- keep account derivation and recovery choices in the application;
- use the same passkey across web, iOS, and Android applications tied to the same domain.
Installation, guides, compatibility information, the security model, the API reference, and the live demos are on the mera documentation website. The passkey PRF model shows how stable PRF output determines account data.

mera is in preview. The API may change before 1.0. Category Labs has completed an internal security review. The documentation describes its security model and known authenticator support.
Issues and pull requests are welcome. See the contribution guide and code of conduct.
