The **Scrypto DeFi Challenge** was a five-week remote hackathon organised by RDX Works and hosted on [Devpost](https://scryptodefi.devpost.com/), running from 20 February to 24 March 2023. It challenged developers to build [decentralized finance](/contents/tech/core-concepts/decentralized-finance-defi) applications in [Scrypto](/contents/tech/core-protocols/scrypto-programming-language), Radix’s [asset-oriented](/contents/tech/core-concepts/asset-oriented-programming) smart-contract language. The event drew [434 registered participants](https://scryptodefi.devpost.com/) and closed with 17 submissions competing for a $50,000 XRD prize pool.

## Format and prizes

Entries had to be written in Scrypto v0.8 or later and submitted as a pull request to the [scrypto-challenges](https://github.com/radixdlt/scrypto-challenges) GitHub repository, with a frontend built using the [Radix dApp Toolkit](/developers/frontend/01-radix-dapp-toolkit) and the then-current Radix Wallet developer preview. Judges scored submissions on the quality and “asset-oriented-ness” of the code, breadth of functionality, creativity of the concept, documentation, and frontend integration.

The $50,000 pool was split across overall placings and two category awards: $11,500 for first, $9,500 for second, $7,500 for third, $5,500 each for the best perpetuals and best lending dApps, and $3,500 for each of three honorable mentions.

## Winners

The [results](https://www.radixdlt.com/blog/scrypto-devpost-defi-challenge-results) were announced in April 2023:

- **1st — FlashyFi** by backyard-coder ($11,500), a flash-loan protocol.
- **2nd — Stoichiometric** by avincigu, Théodore and Guillaume ($9,500), a stablecoin and concentrated-liquidity DEX.
- **3rd — ScrillaLending** by aus87 and errollgnargnar ($7,500), a Liquity-style lending and stablecoin platform.
- **Best Perpetuals — Cup Perps** by zygomeb ($5,500).
- **Best Lending — KL Protocol** by Atoumbré ($5,500).
- **Honorable mentions** ($3,500 each): MojitoSwap, Kaupa and DefiFunds.

## Significance

The challenge was one of several Scrypto hackathons RDX Works ran to build a developer base ahead of the [Babylon mainnet](/contents/tech/releases/radix-mainnet-babylon) launch, which brought Scrypto to production in September 2023. The submissions were experimental prototypes published to the [scrypto-challenges](https://github.com/radixdlt/scrypto-challenges) repository — early explorations of lending, perpetuals, stablecoins and DEX designs in an asset-oriented model — rather than production dApps. It followed the network’s earlier in-person developer outreach such as the [Scrypto Developer Event](/contents/history/scrypto-developer-event) in Lisbon.
