About

1inch provides a suite of powerful tools that enable developers to build smooth DeFi experiences on Ethereum, Ethereum L2s, and beyond. Hackers can utilize our open-source SDKs, smart contract protocols, and robust APIs to build onchain applications. In this hackathon, we are giving builders three distinct challenges:

Build applications with extensive use of 1inch API
Extend our Limit Order protocol with creative trading strategies for users
Expand the reach of 1inch Cross-chain Swap (Fusion+) to one of the following EVM and non-EVM chains: Sui, Aptos, Bitcoin/Bitcoin cash/Doge/Litecoin, Tron, Ton, Monad, Near, Starknet, Cardano, Stellar, XRP Ledger, ICP, Tezos, Polkadot, EOS, or Cosmos.

1inch Limit Order Protocol is an onchain orderbook that can be extended to do much more. Build advanced strategies and hooks for the 1inch Limit Order Protocol like options, concentrated liquidity, TWAP swaps, etc.

Qualification Requirements

Requirements:

Onchain execution of strategy should be presented during the final demo
Custom Limit Orders should not be posted to official Limit Order API
Consistent commit history should be in the GitHub project. No low or single-commit entries allowed!

Stretch goals (not hard requirements):

1inch offers a variety of REST APIs that make building onchain applications simpler. Create a full dApp using as many 1inch APIs as possible.

Example integration points:

Add swap functionality with one of our swap protocols (1inch Cross-chain Swap (Fusion+), Intent-based Swap (Fusion), Classic Swap, or Limit Order protocol)
Source onchain data using our data APIs (price feeds API, wallet balances API, token metadata API, and many more)
Post transactions our Web3 API to interact with the blockchain

Qualification Requirements

Application should use 1inch API as much as possible
Consistent commit history should be in the GitHub project. No low or single-commit entries allowed!
