Possum - ONE | Devpost

Inspiration

DeFi is great but not perfect.

From the point of view of demand, crypto's infrastructure is indeed too imperfect. Although innovation and iteration change with each passing day, participating in such a complex market is challenging.

Many people give up on the experience because the process and logic are too complicated, missing out on the opportunities that are right in front of them. Many people waste a lot of time because they don't know technology and can only do loads of stuff with their own hands. Many non-crypto-native users lose interest in participating because they don't understand the complex DEFI logic. Many people miss out on DeFi's high income because of worries about yield and market volatility and opt for bank time deposits with less than 3% APR.

ONE is aiming to provide the solution for this and not only that ONE is going to provide something DeFi Users want for a long time.

Possum is one crucial part of this.

What it does

By using our unique algorithm, possum can turn every farm into two fix/variable pools. Based on the game model, fixed pool users can have guaranteed APY while the variable user gets higher APY with higher risk.

How we built it

Possum is currently deployed on Aurora Testnet, you can try it out on app.possum.pro. The whole codebase is written by our team and does not fork any other projects. The contract is written using solidity and truffle. Frontend building using TypeScript.

Challenges we ran into

The ambition of ONE is vast. So does the challenge to achieve that. Two major challenge is in our way, one is when designing fix income model, how to balance interests in both fixed and variable pool. On the fixed side, we need to provide considerable fixed APY numbers to attract users. On the variable pool side, we need to provide amazing income potential while controlling the risk they bear. Luckily we find the solution and designed well-organized gaming mechanics to make this happen. Whenever a pool is created, there are some indexes are given to make sure the risk and income are both acceptable with different pool users. At the same time, fix/variable pool users are in a flexible situation and their deposit can influence the APY on both sides. Another challenge is something we still exploring. For a long time, DeFi farm is something you need to take a lot of time, energy, and attention to do. ONE wants to develop an automation strategy in which you can customize your entry price, exit time/price, withdraw time, etc. The way to work out the solution is tough and we need to polish our solution again and again. But now we already have some reliable results and we are working closely to take them into practice. Besides that, what ONE wants to be, means we have a lot of data collection, system design, on-chain activity track work to be done. So building and testing are always hard to do as well as Product Design and Teamwork.

Accomplishments that we're proud of

Possum is already a very mature fixed-income product and is ready to launch at any time. With Possum Real Fix-income can be first introduced to the DeFi world and is gonna change the whole system.

What's next for Possum - ONE

For possum, we will continue to test and update it on Aurora and hope to be part of the Near-Aurora ecosystem. Possum can be integrated into any protocol on Aurora and can be a vital booster to Aurora Network. In the near future, we are developing what we promised ONE is gonna have. We are currently working on developing an automated DeFi Farm solution and have achieved some progress.
