Inspiration

What it does

It creates a basket of tokens based on user preferences and market cap. It then allows buying and selling those baskets directly with ether, abstracting away dealing with tokens, transfers, and trades.

How I built it

• Made a SetBuyer contract (Set protocol wrapper with built-in liquidity)
• Bootstrapped a simple Vue application
• Connected front-end with the SetBuyer contract
• Used Kyber as oracle (offchain) and as liquidity provider (onchain)

Challenges I ran into

• Set Protocol documentation is incomplete.
• The contracts are often not verified and ABI is not easily available (have to build contracts)

What I learned

• Interacting with Kyber onchain
• Set Protocol quirks
• Creating Subgraph

Deliverables
