🏆 Breakout Winners

Colosseum has announced the results of the Solana Breakout Hackathon, the 11th Solana Foundation hackathon and the third hosted by Colosseum. 

This global online competition brought together more than 10,000 developers and founders from over 140 countries who submitted a total of 1,412 final projects, making Breakout the largest crypto hackathon to date. 

Here are the winners:

Be sure to check out the rest of the winners, honorable mentions, and give them all some love!

Announcing the Winners of the Solana Breakout Hackathon

🚀 Accelerator Cohort 3

Colosseum also announced its third Accelerator cohort. The batch is composed of founders from the Solana Breakout Hackathon and our ongoing Eternal challenge. 

From the pool of winners, Colosseum selected 10 startups that exhibited the technical talent, speed, vision, and competitive drive required to build successful, enduring products to invest in and accept into the accelerator program. 

The teams selected for the Colosseum Accelerator Cohort 3 are:

🤫 Arcium Confidential SPL Token

Arcium announced the Confidential SPL Token, a proposed Solana token standard that natively encrypts amounts, balances, and metadata while preserving the familiar SPL-Token developer experience. 

The new standard unifies four pieces of existing infrastructure into one program set, eliminating the headaches that stalled earlier privacy efforts: 

  • SPL Token
  • Token-2022
  • Confidential Transfer extension
  • Arcium’s MPC-powered encrypted compute

Onchain programs can now see and move confidential balances, senders can create accounts for recipients, and any public SPL asset can be “wrapped” into a canonical confidential version on demand. 

These updates unlock practical, privacy-by-default use cases such as institutional payroll, vendor payments, private stablecoins, and confidential DeFi or RWA trading.

The specification is in active development with ecosystem partners, and early-access slots for selected teams will be announced soon.

📜 Solana Ecosystem Report

The Solana Ecosystem Report by Helius for the first half of 2025 shares how Solana has moved from potential to execution. 

It records fifteen months of uninterrupted uptime, daily throughput north of 160 million transactions at sub-penny fees, and monthly real economic value topping half a billion dollars, figures that now outpace every other chain. 

Developer momentum is growing as well: 

  • More than 7,600 new builders joined in 2024
  • Colosseum’s Breakout set a hackathon submission record
  • Superteam network is seeding projects in twenty countries

On-chain activity is showing strength too. 

Solana is handling four-fifths of all DEX trades, its stablecoin float has risen 7x in eighteen months, and regulated asset managers such as BlackRock and Franklin Templeton are bringing tokenized funds and credit vehicles onto Solana. 

At the infrastructure layer, multiple independent validator clients, the Confidential SPL work, and forthcoming Firedancer and Alpenglow upgrades aim to cut finality below 150ms while slashing validator costs.

Case studies on Helium Mobile, Hivemapper, Baxus, and R3 show how Solana’s low-latency architecture, token-extension toolkit, and mobile stack translate into successful consumer products.

This report provides key insights for anyone building apps that tap both consumer growth and the incoming wave of institutional capital.

Solana Ecosystem Report (H1 2025)

🏦 RWAs in Onchain Finance

This in-depth RWA report from Redstone shows that tokenization has moved well past trial projects. 

The value of non-stablecoin RWAs on public blockchains climbed from about 5 billion dollars in 2022 to more than 24 billion dollars by June 2025.

Private credit now accounts for roughly 14 billion dollars and tokenized US Treasuries for 7.5 billion, with six funds led by BlackRock’s BUIDL product holding almost ninety percent of that Treasury pool. 

The authors identify two remaining technical hurdles of native confidentiality and reliable pricing feeds, and point to Solana’s forthcoming Confidential SPL standard and RedStone’s multi-source NAV oracles as the pieces that can let programs manage encrypted balances without sacrificing composability.

For founders building RWA applications on Solana the full report details the architectures, compliance frameworks, and liquidity pathways that have already attracted large institutions such as Apollo, Ondo, and Franklin Templeton to the network.
