1,359 projects were submitted to Colosseum’s Radar hackathon, a contest for Solana-based programs to win some prize money — and possibly a seed check from Colosseum’s startup accelerator wing. The judges’ decisions were announced this morning.

You can view Colosseum’s hackathons, which are backed by the Solana Foundation and a slew of big names in the blockchain’s ecosystem, as a proxy for what would-be Solana founders are most interested in at the moment. The last Colosseum hackathon was won by ORE, a proof-of-work-like currency on Solana.

This particular hackathon turned up a lot of DeFi builders, one of the hackathon’s organizers said. The grand champion was Reflect, a delta-neutral currency protocol that lets tokens accrue yield without touching the banking system. 

Reflect is similar to Ethena, a “synthetic dollar” protocol that raced to billions-worth in market capitalization after launching earlier this year. Underpinning Ethena and Reflect is a version of a cash-and-carry trade which involves buying a spot asset and its corresponding derivative to hedge exposure. The projects are “delta-neutral” because the two positions are offset, and price movements won’t affect assets’ value.

In the crypto version, the derivative is a perpetual futures contract which allows Ethena and Reflect to generate yield from the funding rate, or a fee paid between long and short sellers in a crypto perps market. 

Reflect also generates yield by having users deposit liquid staking tokens (LSTs) to mint RDC, which can be thought of as a yield-bearing stablecoin. Solana LSTs generate rewards that are passed on by validators. JitoSOL, the largest Solana LST, currently generates 8.06% in APY.

Staking yield is the whole ballgame for Reflect. Delta-neutral protocols need to find sources of yield, especially when open interest rates decline, and staking rewards could fill that potential gap. The staking yield rate varies with factors including the total number of stakers and the SOL inflation rate being paid to validators.

Ethena, which is built on Ethereum, recently deployed its tokens on Solana as well. However, Reflect sees itself as a more decentralized version of Ethena. The project’s team decided to create Reflect around six months ago after seeing Ethena hit the peak of a deposit frenzy, Reflect’s anonymous co-founder, Nico, told me. 

Ethena holds deposits with large custodians such as Copper and Fireblocks, and it makes trades on centralized exchanges like ByBit. Reflect plans to operate fully onchain by trading perpetuals on the Solana DeFi platform Drift, Nico said. 

Nico added that the more-centralized way Ethena is run can lead to decisions with big security implications, citing the project’s onboarding of bitcoin collateral as a decision that could leave Ethena “more exposed to changes in funding rate.”

Reflect also plans to integrate with Solana restaking platforms Jito and Solayer for a restaked insurance fund that could offload some protocol risk in exchange for some of the protocol’s revenue. 

Reflect wasn’t the only innovative Radar DeFi submission. Colosseum co-founder Matty Taylor told me DeFi was the most competitive track, and the team believes a few of the startups to come from Radar will be “major catalysts” in expanding stablecoin and blockchain usage.

Research

Innovations on Aptos’ technical design through Raptr, Shardines, and Zaptos approach near-optimal latency and throughput by unlocking 100% utilization of network resources, with the capacity to settle 260k transactions per second with latencies less than 800ms. The original Move language was revamped with the launch of Move 2, supporting more expressivity in smart contract logic and a scalable ability to interact with high volume datasets. The ecosystem has benefitted from strong asset inflows, now hosting over $1.3B in stablecoins, $450M in bridged BTC, and $530M in RWAs. Activity in the Aptos ecosystem has grown notably over the past year, with monthly application revenue reaching ~$835k and monthly DEX volumes growing to over $5B, both at new all time highs.
