        # 0xHacked
        This is the demo for [0xHacked](https://0xHacked.com), a trustless bug bounty platform. You can generate the proof of exploit here. However, due to the constraints of ZKP, the generation might be low on Huggingface.
        <br/>
        We recommend [compiling it from the source](https://github.com/0xHackedLabs/zkProver). The generation can be very quick on GPU. For more details, please refer to [0xHacked Documentation](https://docs.0xHacked.com).
        <br/>
        The sample PoC provided below takes ~800s to generate the proof. You can click "SushiRouterExploit.sol" below and hit "Run" to try it!
