One Key. Many Worlds.

We sit directly on top of the Nostr identity layer, so the key that already signs your notes can now sign Ethereum transactions too. Any browser extension or mobile app that supports Nostr (Alby, Nos2x, etc.) works out of the box—no extra wallet, seed phrase, or plug-in required.

Deterministic Addresses from any npub

Your Nostr public key (npub…) deterministically maps to a checksummed EVM address. It’s the same every time, for every chain, and anyone can verify the math. If you have a Nostr account, you already have an Ethereum account—just unlock it with the key you’re using today.

Powered by Account Abstraction

The project is built on ERC-4337 account abstraction. That means:

  • Smart-wallet features like batched actions, sponsored gas, and social recovery (future).
  • Your Nostr key remains the single source of truth, while the smart account handles on-chain work.

A Decentralized Bundler—over Nostr

We’ve re-imagined the ERC-4337 bundler as a Nostr relay service. Instead of a single operator, any relay can pick up user operations, bundle them, and push them on-chain—keeping the mempool open, permissionless, and censorship-resistant.

Plug-and-Play API

Developers can hit our REST/Relay endpoint to fetch npub → EVM addresses. No vendor lock-in, no proprietary SDK—just open JSON over familiar Nostr events.

Every Nostr user is now an Ethereum user—instantly, securely, and without changing their daily workflow.

One identity, infinite possibilities.
