Inspiration

I wanted to build an exchange on Lisk and finally came up with this project

What it does

Our Multichain Decentralized Financial Exchange (Dunaswap) will serve as a comprehensive and secure platform for users to trade various digital assets, including cryptocurrencies, tokens, and other blockchain-based assets. Leveraging the power of multiple blockchain networks, our exchange will provide users with enhanced liquidity, scalability, and interoperability.

How we built it

The project consists of the smart contract and the front end. The smart contract was written with solidity. compile with solidity 8.17 and deployed on Lisk sepolia testnet. The frontend was designed with React, CSS, and metamask wallets. EthersJS was used for the integration of both the front end and back end while communicating with the smart contract ABIs.

Challenges we ran into

This is my first Dex project and it was adventurous. I lot of Tests and retests. Making sure that the token is properly approved before buying was a huge task that i am proud that it worked.

Accomplishments that we're proud of

The whole project working out as expected was an accomplishment. The projects deployed on Lisk Testnet are : https://sepolia-blockscout.lisk.com/address/0x60cF847C6Ea49009ae290F749451F4CB66CAD0B2 https://sepolia-blockscout.lisk.com/token/0xEbb3113e97eeaA16Dcc2FebD6a1617AB731066AE https://sepolia-blockscout.lisk.com/address/0xEbb3113e97eeaA16Dcc2FebD6a1617AB731066AE https://sepolia-blockscout.lisk.com/token/0x5E4e5347eB417982375Ef9BDe0B77F4322FCF79F https://sepolia-blockscout.lisk.com/address/0x5E4e5347eB417982375Ef9BDe0B77F4322FCF79F https://sepolia-blockscout.lisk.com/address/0x1B7a6536f23a16e198246A3f80Cd646f86856F11

What we learned

I learned to properly check and test my contract because this is a Defi application and mistakes are costly.

What's next for Dunaswap Exchange

  1. Fetching prices from a price feed on mainnet
  2. Adding more tokens for trading and exchange
  3. Adding more chains for increase liquidity
