QuantaSwap
Cross-chain atomic swaps between native QRL and native ETH using hashed timelock contracts on both chains. No bridge, no wrapped assets, no custodian: each leg settles natively and the swap secret never leaves the client.
Overview
QuantaSwap is an open-source dApp for trustless cross-chain swaps between the two native coins: QRL on the QRL 2.0 network and ETH on Ethereum. Swaps use the classic hashed timelock contract (HTLC) construction with sha256 hashlocks, so there is no bridge, no wrapped asset, and no operator holding funds. Either both legs complete or both refund after their timelocks.
The same contract artifact is deployed on both chains: the QRL v2 testnet at Q94cd8e406d2bb4ea251dce3f0558941f2ac056ee and Ethereum Sepolia at 0x805100Fa4310B9c0dbb0754E14CbDe827E3b8a3c. The contracts have no owner, no pause, and no upgrade path, and claims are permissionless with the recipient fixed at lock time. An order book server handles coordination only; both parties independently verify locks on-chain before acting.
