The problem Bundler solves

A nice TLDR of the project: https://medium.com/@shahyashs145/making-gitcoin-grants-gasless-bf9a59e93632

This DApp can be used in the four ways I can think of
1.Airdrops
2.Prize Distributions
3.Capital distribution

4. Gitcoin Grants

A naive way of doing the above things is to transfer tokens one by one to required addresses. It wastes too much gas. This is how gitcoin team is doing it in CLR round 6: https://github.com/gitcoinco/web/blob...

I am trying to improve it by making it gasless. If you are transferring ERC20 tokens then you need to have ETH or MATIC to be able to do that. I am leveraging Dai's permit function to be able to do this. (https://medium.com/@Degens/betting-wi...) In gitcoin grants right now most of the donations are using DAI tokens but gitcoin grant requires you to call approve an then the donation happens. I am trying to make it so that it permits and donates in one single transaction. To be able to make it gasless I am going to use Biconomy's relayer network(https://biconomy.io/).

We are planning to add other features on top of this

Challenges we ran into

I knew how to deploy contracts on ropsten but I had to see the matic documentation on how to deploy contract on matic testnet.
