Welcome to HackDefi, the third hackathon in the Stacks 2.0 Hackathon Series.

The explosion of Defi in the last year or two has been spectacular to see. People finally putting their crypto to work! At Blockstack, we love the crypto-economic magic that goes on behind the scenes in Defi and are working to bring that to the Bitcoin ecosystem.

Upon the release of Stacks 2.0 and the implementation of Clarity (Blockstack’s smart contract language), it will be possible to move Bitcoin from the BTC chain to the Stacks Chain and program it to bring Bitcoin into the Defi ecosystem. Imagine pulling 2% of the current Bitcoin market cap, this could grow larger than the current Defi ecosystem's overall market cap!

We’re setting the stage for decentralized finance using Bitcoin with our next installment of the Stacks 2.0 Hackathon Series. The hackathon will leverage open source software and decentralized networks to transform traditional financial products into trustless and transparent solutions without intermediaries.

Come and join #HackDefi to work on the endless possibilities for hacking on Defi with Bitcoin. We look forward to seeing your Defi applications!

Here are some example Defi platforms:

Uniswap - A fully decentralized protocol for automated liquidity provision on Ethereum.
MakerDAO - A platform for decentralized finance such as exchanging tokens or borrowing DAI and earning savings.
Aave - An Open Source and Non-Custodial protocol to earn interest on deposits and borrow assets.
Compound - An algorithmic, autonomous interest rate protocol built for developers.
Yearn.Finance - A decentralized ecosystem of aggregators that utilize lending services such to optimize your token lending.
Curve Finance - Curve is an exchange liquidity pool on Ethereum (like Uniswap) designed for extremely efficient stablecoin trading and low risk, supplemental fee income for liquidity providers, without an opportunity cost.
WBTC Network - WBTC is an ERC20 token that is backed 1:1 by bitcoin. The idea behind the token is to bring the vast liquidity of the Bitcoin network to Ethereum.
Synthetix - Synthetix is a decentralized platform on Ethereum for the creation of Synths: on-chain synthetic assets that track the value of real-world assets.
