376: ASB resumes unfinished swaps after startup r=da-kami a=da-kami Fixes #374 - [x] Save Bob peer-id in database for Alice - [x] Alice: Wait for `10` Monero confirmations in `BtcRefunded` instead of `XmrLocked` (requires extending the RPC to distinguish locked / unlocked balance) - [x] Save Alice peer-id in database for Bob ~~(+ multiaddress and remove params from resume)~~ - [ ] ~~Refactor Bob in test setup (handle event-loop in test setup similar to Alice)~~ I decided against refactoring Bob in the test setup, because eventually we might still want to add concurrent swap tests with multiple Bobs. The refactoring I had in mind would not allow such kind of tests. Generally, the current state of the changes already contains enough added value to open the PR :) Follow ups out of scope - [ ] Parametrize database with role (Alice / Bob) and remove all the (currently useless) mapping between DB and protocol types. - [ ] Alice: Wait for transfer proof ack before transitioning to new `XmrLocked` Co-authored-by: Daniel Karzel <daniel@comit.network>
XMR to BTC Atomic Swap
This repository hosts an MVP for atomically swapping BTC to XMR. It implements the protocol described in section 3 of this paper.
More information about the protocol in this presentation and this blog post.
Quick start - CLI
- Download the latest
swapbinary release for your operating system - Run the binary:
./swap buy-xmr --receive-address <YOUR MONERO ADDRESS> - Follow the instructions printed to the terminal
Limitations
For now, the MVP is limited to testnet3 on Bitcoin and stagenet on Monero.
How it works
This repository primarily hosts two components:
- the
swapCLI - the
asbservice
swap CLI
The swap CLI acts in the role of Bob and swaps BTC for XMR.
See ./swap --help for a description of all commands.
The main command is buy-xmr which automatically connects to an instance of asb.
asb service
asb is short for automated swap backend (we are open to suggestions for better names!).
The service acts as the counter-party for the swap CLI in the role of Alice.
It provides the CLI with a quote and the liquidity necessary for swapping BTC into XMR.
For details on how to run the ASB please refer to the ASB docs.
