Demox Labs

Demox Labs is a San Francisco company building privacy infrastructure for zero-knowledge (ZK) blockchains, starting with the Aleo network. It is the maker of Leo Wallet, a privacy-focused, zero-knowledge cryptocurrency wallet that constructs transactions locally on the user's device and lets holders conceal or disclose any component of a transaction before it is verified on chain. Demox ships developer tooling for the Aleo and Polygon Miden ecosystems: the Aleo SDK and Miden SDK (WebAssembly builds), the Aleo and Miden wallet adapters (modular TypeScript adapters and React components for connecting dApps to compatible wallets), and the public Aleo RPC API, a free JSON-RPC 2.0 endpoint for reading blocks, transactions, transitions, records, programs, mappings, NFTs, and staking data from the Aleo network. Leo Wallet is transitioning to Shield, a next-generation Aleo privacy wallet built by Provable.

Demox Labs publishes 1 API on the APIs.io network. Tagged areas include Company, Blockchain, Zero Knowledge, Cryptocurrency, and Wallet.

Demox Labs’ developer surface includes documentation, getting-started guide, API reference, engineering blog, support, signup flow, authentication, and 13 more developer resources.
