Improving on-chain debt via emerging DeFi primitives — Options

Issue stablecoin loans collateralized by asset + corresponding put option.

How it works:

$DUSD is a meta-stablecoin index backed by Curve LP tokens. It aims to provide the easiest and safest way for users to store value in stable digital assets. To that end, the DefiDollar team is championing a Curve proposal to add an Aave-Dai/sUSD curve pool. If you think that’s a good idea, please vote with your veCRV here.

The proposed pool will be of particular interest to decentralization maximalists and users who want to hedge against any particular centralized stablecoin failing while also capitalizing on the following:

DefiDollar DAO Token (DFD)

DefiDollar ($DUSD) aspires to be a risk-insured stablecoin layer for DeFi. It aims to provide a safe and stable way for users to hold their assets. In the shorter term, $DUSD is a stablecoin optimized for peg safety, yield and diversification. Just recently, we shared our vision, roadmap and DFD — the DefiDollar Governance token and details around the retroactive token distribution.

Introducing the DFD Liquidity Mining

We have been working on a new mechanism to ensure a balanced and healthy distribution of the $DFD token.


Honest farmers need to deposit $DUSD to participate in the initial liquidity distribution. $DUSD can be minted with DAI…

DefiDollar (DUSD) is an index of stable coins that uses Defi primitives to stay near the dollar mark and subsidize the collateralization ratio. Our vision behind DUSD is to provide an avenue for diversifying your crypto-dollars position; to dampen the potentially disastrous effects of a particular stablecoin like tether failing (partially or completely) from its peg.

DUSD was originally built for the ETHGlobal HackMoney and the details about the first design were published in the following post. Here is a quick demo video.

In this post, we propose a revised DUSD design that allows for higher yields, a more robust…

Quite recently there has been a lot of discussion about Dai moving from its peg and the hassle of involved governance proposals to maintain its stability. Also, even centralized stable coins are often trading above or below the peg.

Other risks associated with centralized coins include counterparty risk, bank run risks, asset seizure risk, and effects from negative interest rates.


DefiDollar is an attempt at being an index of stable coins that uses Defi primitives to stay near the dollar mark and subsidize the collateralization ratio. …

An alternative to traditional banking

Banks are the backbone of every economy. People make deposits, the banks set-asides a portion as reserves and lend the rest on which they charge interest. They also provide an interest to the depositors, and the difference between what they make from lending out and what they pay the depositors becomes their income. It is of paramount importance that banks remain healthy financially.

In the traditional banking system, when we deposit our money in a particular bank with an intention to receive interest payments, we trust the bank’s judgement to fund loans and collect repayments…

In this post, I aim to familiarise the reader with some tools to implement Zk-SNARKs on ethereum. For the sake of the illustration, I’d be walking through our project that my team worked on during ETHSingapore; ZkDai - perform ZCash like private DAI transactions on Ethereum.

Using ZkDai one can shield the transaction sender, recipient and the amount. We got the MakerDAO API sponsor prize for the project! Our submission, along with the demo video can be found here and the github repo here.

Recently, a lot has been written on zero knowledge proofs, however in spite of that, the…

A healthy internet is decentralised. It is open, inclusive, neutral and safe. However, our entire internet experience as we see today is governed by a few organisations who often have economic incentives to work on closed systems that harm the internet interoperability; and consequently, we’re losing on transparency and participation along with it. The idea that these few organisations make decisions behind closed doors that eventually affect our internet experience sounds totalitarian to me.

I participated in ETHIndia, the Asia’s biggest Ethereum hackathon. It was one heck of a buidlful weekend from August 10–12, 2018. It was my first hackathon ever and turned out to be a truly fulfilling experience. We also emerged as one of the 7 winning teams. Yay!

Talks and workshops

The opening ceremony started with the sponsors giving quick intros of the cool products that they are building. Following that, the day witnessed a mix of awesome workshops and talks. The audience warmed up with an Introduction to Solidity workshop. It was followed by a talk by the founder of Dharma. The team…

So the other day I was reading about the decentralized autonomous organizations (DAO) on the blockchain. DAOs are leaderless organizations that function according to a pre-decided digital constitution. These orgs are borderless, permissionless and function without any possibility of downtime or censorship. They do not have a physical address, nor people in formal management roles. In a nutshell, these are unstoppable organizations — that can operate without the fear of a government or a malicious third-party interfering. I also came across the Aragon project. Aragon provides a framework for creating DAOs, with opt-in decentralized applications (DApps) to govern and manage…
