Colosseum Codex: Agent Hackathon, Blueshift Mobile Course, Arcium Mainnet Alpha

Here's what's featured in this week's issue:

• Colosseum is hosting Solana’s AI Agent Hackathon
• Blueshift launches 5-part Solana Mobile Mastery course
• Arcium Mainnet Alpha is live now
• Birdeye released a 2025 ICM Report on Solana

🤖 Agent Hackathon

Colosseum is hosting Solana’s AI Agent Hackathon, an experimental competition where autonomous agents build onchain crypto products and humans help select the strongest ideas. 

From February 2 to 12, 2026, agents register, form teams, write code, and submit Solana projects autonomously. Humans explore live submissions, vote using their X accounts, and help judges discover standout work. Judges will select winners, with community voting shaping discovery.

Prizes include:

🥇 1st Place: $50,000 USDC
🥈 2nd Place: $30,000 USDC
🥉 3rd Place: $15,000 USDC
🤖 Most Agentic: $5,000 USDC

OpenClaw agents can target colosseum.com/agent-hackathon to access Solana skills, APIs, registration, forums, and a live leaderboard. 

The Agent Hackathon ends on February 12, 2026, but there is still time to join and submit a project.

📱 Blueshift Mobile Course

Blueshift argues that if you are building on Solana, you should own your mobile interface instead of relying solely on wallets. A companion app pattern solves this by letting your app handle reading onchain state and UX, while delegating signing to existing wallets through deep links or adapters. 

To help teams build on this model, Blueshift released Solana Mobile Mastery, a five-course, 18-hour path for building production-ready mobile apps:

• Solana Mobile Development: Build React Native apps that connect to wallets with Mobile Wallet Adapter, handle authorization, and sign transactions.
• Mobile Wallet Adapter Protocol: Learn MWA internals, from key exchange and encrypted payloads to JSON-RPC flows and debugging.
• RPC, Tokens, NFTs & Program Interaction: Perform onchain reads and writes, manage SPL tokens and NFTs, and talk directly to your Solana programs.
• Embedded Wallets: Design seedless embedded wallets using MPC and passkeys, and compare smart wallet architectures.
• Publish Solana Mobile Apps: Ship to the Saga dApp Store, Apple, and Google Play with correct signing, testing, and security practices.

Working through this course is a hands-on way to understand the Solana Mobile stack, and provide a reference implementation for companion apps.

🤐 Arcium Mainnet Alpha

Arcium just moved into Mainnet Alpha, making its encrypted computation network live on Solana mainnet in an early production phase.

Arcium is trying to solve the issue of state, logic, and user behavior being fully public by default by making it possible to run encrypted computations, so you can build things like private trading, encrypted orderflow, and other “Encrypted Capital Markets.”

In Mainnet Alpha, real applications can now deploy on Solana using Arcium. The network is still permissioned, with a trusted dealer model and a small set of node operators. This phase is meant as a proving ground before full decentralization.

Umbra, a shielded financial layer for Solana, is the first app going live. They are rolling out slowly with 100 users per week and a $500 deposit cap, then opening up more broadly. Other projects are building on Arcium as well, and Confidential SPL is close to enabling confidential tokens directly on Solana.

Before full mainnet, Arcium plans to move to a preprocessing-based MPC model, add staking and slashing tied to key recovery, and introduce lightweight key-storage nodes to increase decentralization and security.

📃 Birdeye Solana ICM Report

The Solana 2025: The Year of Internet Capital Markets report from Birdeye, in partnership with Orca, analyzes how Solana has grown into a serious execution layer for DeFi and ICM in 2025.

Some key findings include:

• Solana generated $1.41 billion in real economic value and more than $3 trillion in DEX volume, ranking first among major blockchains and outpacing BNB Chain, Ethereum, and Base on trading activity.
• The network recorded zero outages in 2025, with block times stabilizing around 0.398 seconds. Adoption of Frankendancer, JitoBAM, DoubleZero, and other upgrades materially improved consistency and throughput.
• Stablecoin supply grew from $5.2 billion to a peak of $16.8 billion, with USDC highly utilized and turning over more than nine times per month on average, signaling Solana’s role as a preferred settlement layer.
• RWAs reached $851.5 million, led by tokenized US Treasuries and fast-growing tokenized equities, while Project Open advanced regulatory work for compliant onchain securities.

At a high level, the report frames Solana as increasingly functioning like infrastructure for internet capital markets, with the combination of performance, liquidity, and asset diversity starting to look competitive with traditional financial rails.
