Inspiration

As Ethereum developers (who did not know each other before this hackathon), we had one thing in common: we found it cumbersome and inefficient to get financial data from both inside and outside the blockchain into our smart contracts instantly and freely. The options for price data oracles that exist today did not fit our needs, so we built this one.

What it does

OrFeed allows smart contracts to access financial data (such as cryptocurrency prices, Forex exchange rates, and more) instantly and freely.

How we built it

We leveraged Kyber, Uniswap and Synthetix to build the smart contract. We leveraged vanilla CSS and Javascript to build the documentation site.

Challenges we ran into

Solidity does not have a decimals datatype, so pricing data can get interesting when you're dealing with ERC20 tokens with 18 decimal pseudo-places and 2 decimal places for traditional assets.

Accomplishments that we're proud of

Making this work. Additionally, the premium feed feature that we will add soon.

What we learned

Interesting ideas around how a DAO can manage a smart contract ecosystem.

What's next for OrFeed

We are developing a premium feed feature and creating incentives for app developers to become oracles/stake assets on the OrFeed platform. Additionally, we will be reaching out to our developer networks add participation requirements to include more data.
