Irrigate is a platform that gather NGOs and associatons with donors from around the world, using Ethereum blockchain and Aave protocol.
NGOs and associations can submit a form to the app and appear in the main page after going through a validation process.
Donors can register and see all the NGOs and associations available for donations.
The project has been built during and for the SOS Hackathon in June 2020.
Presentation can be found here
It's still in a proof of concept state, so security checks have to be performed.
Also, all the informations contained such as NGO's names and descriptions are used for the hackathon purpose only.
NGOs and associations interactions with the app
A form has to be filed and validated for the project to be visible on the app's main page.
Below items have to be provided:
- Name of the association
- Short description
- Category
- Continent of activity location
- Country of activity location
- An ethereum address that will receive the donations
- A logo that will be displayed on the main page
Donors interactions with the app
Make sure you have Metamask on your browser, and connected to Ropsten network.
Donors can register providing an email and a password.
Then they can login and start adding associations to their project list by clicking on the "Add cause to your donation stream" button below each project.
By clicking on the "Manage your stream" button, users can view their association's list.
They can also make a one time donation by setting the amount and validate the transaction on Metamask.
Attention:
Donation to multiple projects in one time is not implemented yet, only the first project in your list will receive the donation.
The monthly donation is not implemented yet.
Aave protocol
Aave protocol is used to earn interests.
The Lending Pool, the DAI token and the aDAI token contracts are the ones provided by Aave on Ropsten.
Aave protocol addresses can be found here
The strategy behind:
The donations:
The app works by batches of 15 days. All the donations in DAI made by the donors are sent to a common address, then every 15 days all the DAIs are deposited to Aave Lending Pool. The interests are redirected to a second address. After 30 days, the exact deposited amount is redeemed back to the common address and the donations are transferred to the correct associations addresses.
The data:
When a user makes a donation, the amount of the donation is added to the association account in a batch that saves all the donations performed during these 15 days. The batch is saved in a MongoDB database with the name in a form like YEAR_MONTH_A or B corresponding to each half of the month.
For example June 2020 is divided in two batches: 2020_6_A (from 1st to 14th) and 2020_6_B (from 15th to 30th).
After the interests period of time, the batch containing the donations record is retrieved and all the amounts are transferred to the associations.
The interests:
Every 1st day of the month, all the interests are redeemed and converted into DAIs.
Then, the total amount of earned interests is compared to the app's last month expenses: gas cost of all the transactions + server cost.
After deduction of the expenses, the remained amount of interest is transferred proportionally to the associations.
This last step has not been finished to be developed yet.
Security
This project is a prototype, it is not recommended to use it on the mainnet.
No smart contracts are used, only web3 calls are performed on ropsten.
Improvements to be made:
Short term:
- Possibility to add multiple categories by association/projects
- Display real time statistics of each projects data: total subscribers, total donations received
- Display real time app statistics: total amount redistributed, total interests earned and redistributed
- Develop multiple projects donations at one time, donation amount will be divided between all user's projects
- Develop monthly donation subscription
- Email implementation for user contact and registering
- Security validation for the forms
Long term:
- Add GSN to reduce users gas cost when making donations
- Develop mobile app version
- Deploy smart contracts containing the code for transparency
- Allow connection with other wallets (currently Metamask only)
- Audit code and smart contracts for security
- Secure the app accounts with cold and multi-signature wallets
- Own logo and design
