Endow

EnDow is an application developed by the following team🥇 as a submission to the

Abdul Wasay Mehar - github: @masterrom Francisco Angulo D - github: @ttymarucr David Krett - github: @eydbk Anand Singh - github: @darknightdev

Problem Being Addressed

  • The problem our application addresses, is it provides a easy and UX friendly way for Crypto Hodlers to "stake" there investments and use the rewards generated via yield farming amongst selected low risk lending products

Endow - Is a DeFi proof of donation investment product (nfts) targeted towards HODLERS who want to share their investment rewards from yield farming with community selected (DAO voting) charitable campaigns.

Inspiration

  • our inspiration for this project are the many crypto investors who are HODLERS - our project gives the opportunity for these Hodlers to share yield opportunies by investing in low risk lending protocols and allocating rewards owned to socially beneficial campaigns as donations

What it does

  • investors can invest their crypto holding in Endow
  • investors investments are invested in a lending product (currently DAI - more to be added later)
  • investors are issued Endow governance tokens for their investment - in future we will also issue share tokens to provide liquidity
  • these investments are invested in AAVE via Endow's governance DAO (Aragon)
  • Campaigner can post a socially beneficial campaign for donations on Endow - when they post their campaign they are issued with an NFT
  • Investors vote via the DAO as to which Campaigns can elegible for donations from earnings on the investment pool
  • During a predesignated voting periods - investors can use their governance tokens to selectively allocate their rewards for donation to the elegible campaigns in the donors pool
  • At the end of each voting period the investors rewards and donations are recalculated - the investor receives a Proof of Donation ERC 1155 NFT issued by each campaign they have donated to as an official receipt for their donations

How we built it

  • hardhat chainlink starter
  • solidity smart contracts
  • react UI
  • Aragon Dao
  • Aave
  • Moralis
  • Alchemy
  • Polygon
  • Chainlink Keepers
  • ERC1155 @openzeppelin

Challenges we ran into

  • time we all have full time jobs

Accomplishments that we're proud of

  • how we were able to integrate modular components ie chainlink, openzepplin, aragon dao, aave into an easy to use investment protocol
  • issuing nfts to represent each campaign and erc1155 Proof of Donation tokens

What we learned

  • DAO protocols, Ave

What's next for Endow

  • further development including share tokens, security review
  • deployment of UI to IPFS
  • additional investment protocols

Smart Contracts

To facilitate our application several smart contracts were developed - as follows

  • ITokenManager.sol - manages governance token issuance and burning with the Aragon Smart Contract
  • IVoting.sol - manages voting for elegible campaigns and for selecting for each investor supported campaigns
  • CampaignLauncher.sol - manages the workflow for a campaigner to submit, obtain approval and donations for each campaign - this contract also manages the issuance of NFTS for campaigns as well as NFTS for proof of donation by calling the EndowTokenManager.sol contract
  • CampaignVotingManager.sol - manages the submission of campaigns for voting
  • CampaignDonationKeeper.sol - A keeper is used to get the donation votes for each campaign
  • CampaignReviewKeeper.sol - A keeper that manages the approval vote for any newly submitted campaigns
  • AAVEDAIDDonorsPool.sol - A contract for managing investors investments into the investment/donation pool
  • IDonor.sol - interface to track donations
