PolySave is a personal saving decentralized app built on the polygon blockchain whereby users can deposit funds they want to lock for a period of time.
PolySave is inspired by Piggyvest. Piggyvest is also saving platform where users can save funds.
PolySave is segmented to 2 parts;
The smart contract is written in solidity.
The development, verification and testing of
the contract was done with these;
Hardhat - To bundle/bootstrap the entire contract development enviroment
Ethers - To interact with the blockchain
Alchemy - Alchemy node used to send and query requests
Metamask - Wallet used to inject web3 enviroment into the browser
The Frontend of the dApp was done with these technologies;
ReactJS/NextJS - Used to create the entire website
Rainbowkit - For wallet connection/integration
Ethers/Wagmi - For smart contract interaction
Tailwind CSS - For styling the entire website
Coming up with a design was quite challenging because in addition to me not being a designer, there wasn't so much time to come up with a new design.
I was able to practicalize some of the things we were taught by our instructors during the bootcamp phase.
An investment segment added to the app whereby several users invest their assets together for a period of time and the the funds can be used for yield farming/liquidity pool provision and the the profits are shared among all users based on percent of their initial investment
To run this project, you will need to
- Create an
.env.localfile to the root of the piggy folder - Then add this environment variable to your .env.local file
NEXT_PUBLIC_ALCHEMY_KEY="<your-alchemy-key>"
get this key from Alchemy
To run this project Locally, make sure you've configured your environment variable, then run the following commands in Terminal:
cd piggynpm installto install dependenciesnpm run dev
the app would be running in the localhost link shown in the terminal.
Because this is a personal savings app, there are
functions that can only be called from the owners account.
To check these out you might need to redeploy the contract
or I transfer ownership to your account.
Since that can be tedious, I've attached a demo video link
that shows the functionalities of the app and also a live site link
