Contract Address and ABI of DInterest.sol in v3?

[saxenism]

Need to integrate 88mph in my dApp.
Only a basic functionality required, where the user must be able to deposit x DAI for y number of Days in the fixed interest instruments of 88mph.

For v3, I found the contract that I would like to integrate in my front-end. That is the DInterest.sol contract, available here: https://github.com/88mphapp/88mph-contracts/blob/v3/contracts/DInterest.sol. I am interested to know the contract address (deployed on Rinkeby) and its ABI.

Unable to find it here: https://github.com/88mphapp/88mph-contracts/blob/v3/deployments-exported/rinkeby.json

Also, if for my use case, I have to use some other contract and not DInterest.sol, do let me know.
