Braavos

Braavos is a self-custody smart-contract wallet for Bitcoin and Starknet, available as a browser extension and mobile app. Built on Starknet account abstraction, it adds hardware-backed two-factor signing (mobile secure element and passkeys), session keys for dApps, gas abstraction, in-wallet swaps, staking, and fiat on-ramp. Its developer surface is the injected Starknet wallet API (get-starknet), the Braavos Cairo account contracts, and first-party JavaScript libraries (session keys, deeplinks, StarkNet URLs, dApp metadata) published under the myBraavos GitHub organization. Braavos does not publish a hosted REST API or OpenAPI. Sector: crypto. Backed by Pantera Capital.
