💫 ETH-XMR atomic swap implementation

ETH-XMR Atomic Swaps

This is an implementation of ETH-XMR atomic swaps, currently in beta. It currently consists of swapd and swapcli binaries, the swap daemon and swap CLI tool respectively, which allow for nodes to discover each other over the p2p network, to query nodes for their current available offers, and the ability to make and take swap offers and perform the swap protocol. The swapd program has a JSON-RPC endpoint which the user can use to interact with it. swapcli is a command-line utility that interacts with swapd by performing RPC calls.

Swap instructions

Trying it on mainnet

To try the swap on Ethereum and Monero mainnet, follow the instructions here.

Trying it on Monero's stagenet and Ethereum's Sepolia testnet

To try the swap on Stagenet/Sepolia, follow the instructions here.

Trying it locally

To try the swap locally with two nodes (maker and taker) on a development environment, follow the instructions here.

Protocol

Please see the protocol documentation for how it works.

Additional documentation

Developer instructions
