[DearNadia]

Prize Title

Limit order adapter for the 1inch Liquidity Protocol

Prize Bounty

3,000 USD in 1INCH Tokens

Challenge Description

An adapter for creating limit orders over the 1inch Liquidity Protocol or over any decentralized exchange (DEX), based on their available liquidity. The adapter should contain isValidSignature, getMakerAmount (which calculates return amount based on DEX "getReturn" function) and transferFrom (which triggers swaps and sends to takerAddress)..

1inch limit order protocol is a set of smart contracts, that can work on any EVM based blockchains (Ethereum, Binance Smart Chain, Polygon, etc.). Key features of the protocol is extreme flexibility and high gas efficiency that achieved by using two different order types - regular Limit Order and RFQ Order. Smart Contract allows users to place limit orders and RFQ Orders, that later could be filled on-chain. Both type of orders is a data structure created off-chain and signed according to EIP-712.

Judging Criteria

Solution must be unique and it must work. We expect demo, not presentations We'll do a code review to ensure code quality to make the final decision.
