[P2] - Revenue-generating Limit Order 🏅

We used Truffle to effortlessly scaffold a complicated dapp development environment on Polygon and Arbitrum in no time! The Truffle config template already includes Infura rpc-related config code which made it super convenient for us to test and deploy our smart contracts on both Polygon and Arbitrum with the multi-network config setup. We built an easy-to-use automated limit / range order tool by providing liquidity on Uniswap V3 and automatically close the position once the order is fulfilled. As compared to a market order, a limit order allows you to set a specified limit price for token swaps. Leveraging single-sided liquidity on CLMM DEX's for better swaps with no slippage, Aperture brings you the first-ever revenue-generating limit (and range) orders for trading token on Polygon! Just pick a price target or select a range -- when your order gets filled, you get the tokens at your ideal price, and earn extra trade fees through the process!

The Magic Wallet SDK enables a seamless experience to onboard the crypto-curious user group who is not comfortable operating a traditional non-custodial wallet like MetaMask. This helps attract those traders to try and place limit / range orders through our tool.

In this ETHDenver demo, we incorporated Tenderly’s simulation API to avoid broadcasting potentially already-executed transactions. If the transactions are already processed, then it shouldn’t be executed again.

In this ETHDenver demo, we incorporated both Relayer and Autotask and these are well integrated into our limit order service to provide users with smooth experience. Defender is crucial through out our operation stack: from packaged relayer service to automated scheduling. Before using Defender relay service, we used to write lots of JS code to manage gas estimation and handle errors. Now we can abstract that away first a few lines of code. The same applies to scheduling: we were managing scheduling using AWS’s EventBridge Scheduler coupled with Lambda functions.

Polygon's low gas fee and rich ecosystem of DeFi application are a massive enabling force for Aperture to build on top of it and to onboard the next wave of new DeFi users. With Chainlink's support for Polygon, Aperture is able to automate complicated DeFi operations for users and offering web2 experience for the web3 DeFi world.

Our project uses Chainlink Automation to check for limit and range order status, and automatically close the position and disburse the output token to the user once the order is fulfilled. As a concrete example, let's say the current ETH price is 1600 USDC; a user places a range order (1600, 1900); our smart contract creates the corresponding liquidity position on Uniswap V3, and create a Chainlink upkeep within the same atomic transaction. The upkeep task checks whether the liquidity position has been fully converted to USDC (i.e. ETH price rises to 1900 USDC or above), in which case `performUpkeep()` would close the position and disburse the USDC to the user.
