HodlUp is a Decentralized DCA web3 Dapp
- You can see the video here : https://youtu.be/WgnW4xoq28k
- Dapp deployed on Vercel : https://hodl-up-sjouany.vercel.app/
- Clone gitHub repository
- Install dependencies on truffle folder and client folder
$ npm install- Prérequisite : launch ganache with a polygon fork
- Replace ALCHEMY_ID by your own alchemy ID and set your mnemonic
$ ganache -f https://polygon-mainnet.g.alchemy.com/v2/ALCHEMY_ID -u 0xe7804c37c13166fF0b37F5aE0BB07A3aEbb6e245 --networkId 137 -m "put your wallet mnemonic here"- from truffle launch truffle test (don't forget before to update informations inside truffle-config.js)
$ truffle test --network polygon_fork --to 01- Test report

44 passing (4m)- Same prerequisite than previous chapter for unit tests : you have to launch ganache with polygon fork
$ ganache -f https://polygon-mainnet.g.alchemy.com/v2/ALCHEMY_ID -u 0xe7804c37c13166fF0b37F5aE0BB07A3aEbb6e245 --networkId 137 -m "put your wallet mnemonic here"- from truffle folder:
$ truffle migrate --network polygon_fork --to 01- To provide tokens to the wallet and initialize values for the smart contract s
// update 'myAddress' on init_demo.js
$ cd scripts/demo_local_fork; node init_demo- from client folder:
$ npm run dev- Dapp is now available here: http://localhost:3000/
-if you want to simulate a swap you can execute following command from truffle folder
$ cd scripts/demo_local_fork; node launch_dca_exec- from truffle folder:
$ truffle migrate --reset --network mumbai --f 02Compiling your contracts...
