# **Introduction** Welcome to the inaugural Cross-Chain Summer Hackathon, brought to you by [Chainflip](https://chainflip.io/), in collaboration with [THORChain](https://thorchain.org/) and [Maya Protocol](https://www.mayaprotocol.com/). The hackathon aims to bring together experienced builders and innovators to create practical applications and tools that enhance the cross-chain ecosystem. We welcome developers with experience in blockchain, smart contracts, and cross-chain technologies. This hackathon is your playground to create new solutions to enhance the cross-chain space using resources and expertise from our partners. Our mission is to overtake the CEXes, with countless opportunities for building supportive infrastructure. Get ready to innovate and transform the cross-chain ecosystem! # **What is the Cross-Chain Summer Hackathon?** As core drivers in the cross-chain ecosystem, Chainflip, THORChain and Maya are unlocking native, composable, and efficient ways to move assets across different chains. By eliminating friction, bridge-related risks, and liquidity fragmentation, we've built innovative solutions powered by Substrate and Cosmos architectures. Over the next month, we invite builders to explore our SDKs, learn about the latest innovations in cross-chain technology, and develop creative solutions and use cases. Join us to make meaningful strides in the cross-chain space with the combined power of Chainflip, THORChain, and Maya Protocol! # **Hackathon Ideas** ### SDK: - Frontend - Wallet Integration - Aggregator integrations - Mobile App - Build a widget ### Chainflip x Thorchain x Maya Protocol: - Connect Maya & Chainflip via Arbitrum - Connect the three protocols via another mechanism - Connect the three protocol using cross-chain messaging - Create synergy utilising [SwapKit](https://swapkit.dev) tools ### General: - Liquidity management tooling - Dashboards - Build a solution using [Broker as a Service](https://docs.chainflip-broker.io/getting-started/) - Build a solution using [SwapKit](https://swapkit.dev) - Affiliate program for referring new users - Creating deposit channel and sending via sms - Make a zap for funding a validator/broker/lp with any currency - Affiliate LP dashboard - A front end that can connect to a wallet more usable than polkadot JS - Make the [Flippy NFTs](https://opensea.io/collection/flippy-five-thousand) great again # **Developer resources** - Chainflip: https://chainflip.io/ - Chainflip General Documentation: https://docs.chainflip.io/concepts/welcome - Chainflip SDK Documentation: https://docs.chainflip.io/integration/swapping-and-aggregation/swapping-basics - Chainflip GitHub: https://github.com/chainflip-io - Broker as a Service: https://docs.chainflip-broker.io/getting-started/ - Staked FLIP (Thunderhead): https://stakedflip.fi/ - Thunderhead Documentation: https://docs.stakedflip.fi/ - THORChain: https://thorchain.org/ - THORChain Documentations: https://docs.thorchain.org/ - THORChain Developer Documentation: https://dev.thorchain.org/ - THORChain GitHub: https://github.com/thorchain - THORChain GitLab: https://gitlab.com/thorchain - Maya Protocol: https://www.mayaprotocol.com/ - Maya Protocol Documentation: https://docs.mayaprotocol.com/white-paper/readme-1-1/introduction - Maya Protocol GitHub: https://github.com/Maya-Protocol - Maya Protocol GitLab: https://gitlab.com/mayachain - SwapKit Website: https://swapkit.dev/ - SwapKit Documentation: https://docs.thorswap.finance/swapkit-docs - SwapKit GitHub: https://github.com/thorswap/SwapKit - Chainflip/THORchain Aggregation Contract: https://github.com/thorswap/evm-contracts/blob/main/src/contracts/aggregators/TSAggregatorChainflip_V1.sol - Builder’s Discord: https://discord.gg/chainflip-community # **Submission Requirements** - Each entry should focus on one specific use case or the general challenge. - Submit a detailed design report that adheres to the specified technical requirements for each track. Make sure your report thoroughly explains how your design meets the objectives and performance standards of the use case. Your entry should showcase careful planning and precision, highlighting your engineering expertise and proficiency. - You are expected to include links to additional detailed reports (e.g., GitHub repository, Google Doc, or Google Drive folder).

SwapKit comes with the benefits of streamlined affiliate fees, improved quotes & gas pricing, robust wallet connectivity, and DEX aggregation enabling swaps between 5,500+ crypto assets across 14 blockchains in a single transaction. - Squid Router - [Squid Router](https://www.squidrouter.com/) allows any token to be swapped between blockchains and unlocks access to apps across chains in a single click. - Nine Realms - [Nine Realms](https://www.ninerealms.co/) provides node operation infrastructure and core development services for the THORChain ecosystem. - THORWallet - [THORWallet](https://www.thorwallet.org/) is a non-custodial wallet with an integrated cross-chain DEX that allows to swap native assets across different blockchains with no intermediary. - Broker as a Service - [Broker as a Service](https://docs.chainflip-broker.io/getting-started/) offers integrators a service to have their own broker without any operational headaches involved. - Framework Ventures - [Framework Ventures](https://dev-frameworkventures.netlify.app/) is a thesis-driven venture firm that builds alongside the founders. - Delphi Ventures - [Delphi Ventures](https://delphiventures.io/) is a thesis-driven, high-conviction firm that allocates across core themes that we believe will dramatically shape the world. - CV VC - [CV VC](https://www.cvvc.com/) is an early-stage venture capital investor with a focus on global startups that build solutions using blockchain technology. # **About the Organisers** ## **Chainflip** Chainflip is a cross-chain protocol that leverages threshold signature schemes, an independent blockchain, and a purpose-built AMM using just-in-time liquidity to facilitate native cross-chain swaps called the JIT AMM. Chainflip grants users access to native assets without the need for bridging or wrapping assets with low slippage, low fees and high capital efficiency. The Chainflip protocol maximizes capital efficiency to enable trades at extremely competitive prices with low slippage, through a decentralized and permissionless network. **Discover more:  https://chainflip.io/** ## **THORChain** THORChain is a network that facilitates native asset settlement between Bitcoin, Ethereum, BNB Chain, Avalanche, Cosmos Hub, Dogecoin, Bitcoin Cash & Litecoin. It is secured by its native token, RUNE, which deterministically accrues value as more assets are deposited into the network. Anyone can use THORChain to swap native assets between any supported chains or deposit their assets to earn yield from swaps. **Discover more: https://thorchain.org/** ## **Maya Protocol** Maya Protocol is an Automated Market Maker (AMM) similar to Uniswap but stands out by utilizing cross-chain liquidity without the security risks associated with wrapping assets and bridging. It manages its  funds directly in on-chain vaults and ensures their security through economic measures. For enhanced security, Maya employs the Tendermint consensus engine, Cosmos-SDK state machine, and GG20 Threshold Signature Scheme (TSS). **Discover more: https://www.mayaprotocol.com/**
