what's JingSwap?

JingSwap is a decentralized exchange protocol built on the Stacks blockchain, a Bitcoin Layer 2 that enables smart contracts secured by Bitcoin. It specializes in large-volume, fair swaps between sBTC (synthetic Bitcoin), STX (Stacks native token), and USDCx, using blind batch auctions to eliminate front-running, sandwich attacks, MEV, and slippage. Users deposit assets into timed pools; after a 60-second buffer, trades settle pro-rata at Pyth Network oracle spot prices, validated by three safety gates: oracle staleness under 60s, confidence interval below 2%, and sanity check against BitFlow DEX within 10%. Unmatched portions auto-roll to next cycles or push directly to wallets, implemented fully on-chain with Clarity smart contracts for security and transparency.

JingSwap won first place in the Stacks Buidl Battle competition.
