What is VladSwap?

VladSwap is a decentralized, peer-to-peer (P2P) marketplace for Partially Signed Bitcoin Transactions (PSBTs). It provides a secure and trustless environment for users to trade Bitcoin-based assets without relying on a centralized exchange or order book.

Core Features​

  • Decentralized Order Book: Orders are propagated and stored across a distributed network of nodes, ensuring censorship resistance and high availability.
  • Trustless Atomic Swaps: Using PSBTs, VladSwap facilitates atomic swaps, where trades are executed in a single, all-or-nothing transaction, eliminating counterparty risk.
  • P2P Communication: The marketplace is built on the subp2p protocol, which uses WebTransport to enable direct P2P communication between browsers and relay nodes.
  • Community-Owned Infrastructure: Anyone can run a vladswap-node to help maintain the network's order book, fostering a decentralized and resilient ecosystem.

How It Works​

VladSwap's architecture is designed to be as trust-minimized as possible. Here's a high-level overview of the process:

  1. Order Creation: A user creates a PSBT that represents their side of the trade (e.g., "I want to sell X amount of BTC for Y amount of Alkanes").
  2. Order Propagation: The PSBT is broadcast to the subp2p network, where it is validated and added to the distributed order book.
  3. Order Matching: Other users can discover the order and, if they agree to the terms, create their own corresponding PSBT to complete the trade.
  4. Atomic Swap: The two PSBTs are combined and broadcast to the Bitcoin network, where the atomic swap is executed in a single transaction.

By leveraging the power of PSBTs and a decentralized P2P network, VladSwap provides a robust and secure platform for trading Bitcoin-based assets, giving users full control over their funds at all times.
