## Projects
- [AcornSwap](https://www.qrlecosystem.com/projects/acornswap/index.html.md): A Hyperion port of Uniswap V2 and V3 for the QRL 2.0 testnet. Its deployed V2 contracts provide constant-product pairs and routing, while the concentrated- liquidity V3 contracts are built and tested but not yet deployed.
- [PQlyMarket](https://www.qrlecosystem.com/projects/pqlymarket/index.html.md): An open-source prediction-market dApp for the QRL 2.0 testnet with market creation, YES/NO conditional-token trading, constant-product automated market makers, liquidity provision, oracle resolution, and a testnet faucet.
- [QuantaPool](https://www.qrlecosystem.com/projects/quantapool/index.html.md): A decentralized QRL liquid staking protocol for staking QRL, receiving stQRL, and earning validator rewards while staying liquid.
- [QuantaSwap](https://www.qrlecosystem.com/projects/quantaswap/index.html.md): 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.
- [Squirrel Game](https://www.qrlecosystem.com/projects/squirrel-game/index.html.md): An on-chain strategy game on the QRL 2.0 testnet where Quantum Computer NFTs mine qBTC and Squirrel NFTs tax or steal it, with Hyperion contracts for minting, staking, traits, yield accounting, and commit-reveal randomness.
