'''LEZ Atomic Swaps''' is a protocol and pair of Basecamp apps for swapping native Bitcoin and LEZ, and it runs on the Logos Execution Zone (LEZ) and [[Logos Messaging]] (Logos Delivery and Logos Chat). The code is published by the GitHub account gateway-fm. The README does not say whether it is an official Logos project.

== What it does ==
* It swaps native Bitcoin and LEZ with no custodian, wrapped asset or bridge operator.
* It uses Taproot and MuSig2 adaptor signatures on Bitcoin and a witnessed escrow on LEZ.
* Makers publish signed offers over Logos Delivery. Takers negotiate in private over Logos Chat.
* The LEZ claim reveals the value the Maker needs to finish the Bitcoin signature, so the swap completes without another Taker message.
* If a swap stops, ordered refund windows let the second leg resolve before the first.
* It ships two Basecamp apps, LEZ / BTC Maker and LEZ / BTC Taker, with Rust services, local chains and explorers.
* Developers can write their own trading policy against a documented owner API.

Stage: Prototype. The README says "the private-local BTC/LEZ product path works end to end". It adds that "Public-network operation, production key management, and an independent cryptographic audit are still in progress."

== Use it ==
The packaged stack targets arm64, including Apple Silicon and arm64 Linux, and needs Docker with Compose.
# Prebuilt: download the <code>lez-swap-stack</code> arm64 bundle from the latest release, unpack it and run <code>./scripts/start.sh</code>.
# From source: clone the repository, go to <code>deploy/</code> and run <code>./scripts/from-scratch.sh</code>. The README says the first build takes hours. Later starts use <code>./scripts/up.sh</code>.
# Open the Basecamp desktop over VNC at 127.0.0.1:5901. The README gives the default password and how to change it.
# In LEZ / BTC Maker, publish an offer. In LEZ / BTC Taker, take it and follow the steps: lock BTC, the Maker funds LEZ, claim LEZ, the Maker claims Bitcoin.
# To install the two apps in Basecamp's package manager, add the module catalogue URL given in the README.
# Stop the stack with <code>./scripts/down.sh</code>.

== Build it ==
* Build from source with <code>./scripts/from-scratch.sh</code> in <code>deploy/</code>.
* Inspect the Rust workspace with <code>cargo metadata --locked --no-deps</code>.
* Run the offline test suite with <code>./scripts/run-public-offline-e2e.sh</code>. It runs in a Linux container with networking off.
* CONTRIBUTING.md sets the rules for formatting, Clippy, licences and DCO sign-off.

== Releases ==
* Latest tag: v0.2.6, 8 October 2026.
* Version in metadata.json: 0.2.5, for both Basecamp apps (lez_atomic_swap_maker and lez_atomic_swap_taker).
* GitHub lists nine releases, v0.1.1 to v0.2.6. The latest is v0.2.6.
