Cross chain atomic trades protocol and api for trades between Stellar and Ethereum
GPL-3.0 License
Protocol and api for doing cross chain atomic trades between Stellar and Ethereum.
Stellar XLM <-> Ethereum ETH
Stellar Asset <-> Ethereum ERC20 Token
The protocol for trades initiated from the Stellar side is working as demonstrated by this script which exercises both parties along the path of least resistance. More testing is required around refunds and edge cases.
Communication would ideally be done by the tool over some channel rather then having users manually send each other data (see last todo item above). These 2 pieces require manual sharing:
These pieces can be found by scanning the ledgers and so don't require communication:
Trades are defined by a trade.json file conforming to the JSON schema here.
