Inspiration
I have been learning web3 development for quite some time now and wanted to test my abilities to not just develop software but also in the shortest time possible. The 100m dash event brought the opportunity I wanted.
What it does
This project is a port of the popular DeFi application Uniswap to Godwoken Testnet v1
How I built it
At the beginning, I deployed all the Uniswap contracts to Godwoken Testnet v1. It was fairly simple and straightforward. Then I started understanding the Uniswap interface code as I wanted to use the same interface used by Uniswap with just the addition of the Godwoken network. Once I understood the flow I began making Godwoken specific changes to the interface. Once I got the interface working with the Godwoken network I deployed mock token contracts.
Challenges I ran into
The most challenging part was getting the wrapping and unwrapping of the CKB token working. Debugging the nft manager contract multicall took a lot of time. Transaction confirmation time is high on testnet, you need to wait for metamask confirmation to know that transaction is mined.
Accomplishments that I am proud of
You can now use the Uniswap interface with all the previously supported networks and the new addition of Godwoken!
