ZETO Brings Browser-Based Access to Peer-to-Peer Bitcoin-to-Monero Atomic Swaps

ZETO web interface uses the eigenwallet swap protocol and includes locally managed Bitcoin keys, peer-to-peer liquidity discovery, and recovery tools for interrupted transactions.

United States, October 13, 2026 -- ZETO is providing a browser-based interface for users looking to swap BTC to XMR through peer-to-peer atomic swaps, using the eigenwallet protocol formerly associated with UnstoppableSwap. The system connects users with liquidity makers over libp2p and is designed to support recovery procedures when a swap does not complete as intended.

A Peer-to-Peer Approach to Swapping BTC for XMR

Rather than exchanging funds through a conventional centralized exchange, ZETO connects a user holding Bitcoin with a liquidity maker offering Monero. The maker provides a price, and the parties proceed through a sequence of cryptographic and on-chain steps.

The swap process includes six main stages:

• Quote: The user requests a price from a liquidity maker over libp2p.
• Setup: Both parties generate key shares and prepare Bitcoin cancellation, refund, and penalty transactions before funds are moved.
• Bitcoin lock: The user's Bitcoin is locked in a 2-of-2 output requiring the relevant parties' signatures.
• Monero lock: The maker locks Monero to an address derived from the participants' key shares and supplies proof of the transfer.
• Redeem: The user provides an encrypted signature. When the maker redeems the Bitcoin, the resulting information reveals the Monero key share needed for the user to access the XMR.
• Safety and recovery: Timelocks and pre-signed transactions provide a route for recovering Bitcoin if the swap stalls, subject to the protocol's conditions and deadlines.
