Colosseum hackathon had some genuinely exciting builds. Here are the 7 projects I found most interesting 👇
1- @orquestradev ; Turns Solana program IDLs into REST APIs and MCP tools. Makes onchain programs as easy to integrate as any Web2 API.
2- @packetchat ; Agent to agent messaging on Solana. The communication primitive multi-agent systems have been missing. ( Dope branding )
3- @ridemarkets ; Onchain prop firm built on futarchy. Call a trade, the crowd bets YES/NO, the treasury executes. Win = 30% of profit. Lose = walk away from a $9 bond. No margin, no liquidation. ( big news at @islanddao )
4-@Voightxyz ; Observability for AI agents. Every prompt, tool call, and decision anchored on-chain. One paste to wire it in.
5- @craftsdev ; Startups tokenize 5–20% equity, backers get real upside via sealed-bid auctions. Fair price for everyone, no insider rounds.
6- @tradeonhunch ; Unified intelligence layer for prediction markets. Aggregates pricing across venues so you never miss the best odds.
7- @GetRektApp ; Trade BTC/ETH/SOL with $1 on mobile. Gamified perps for people who've never touched a trading platform before.
> The projects making Solana easy to plug into AI pipelines infra for agents to read programs, message each other, and get observed are going to matter a lot.
>The chains that win the agentic era won't just be fast, they'll be the ones developers can wire up in an afternoon.
Solana is quietly becoming that chain. @colosseum@solana@solana_ai@toly
AI agents were never fully autonomous.
They could think.
They could use tools.
But they couldn’t truly communicate, transact, or maintain persistent relationships on-chain.
Until now.
Packet MCP is live.
Agents can now:
→ own wallet-native inboxes
→ receive encrypted messages
→ send & receive payments
→ react to live on-chain events
→ maintain persistent communication threads
This is communication infrastructure for autonomous systems.
Not another API wrapper.
Not another hosted backend.
An agent with a wallet can now operate as a sovereign network participant on @Solana

I’m extremely excited right now
I wanted to share the demo video without even editing it. @SolPlay_jonas just introduced the Solana keychain, and I immediately built its MCP version. The final stage of my project is now coming together really nicely. This week will be focused entirely on testing.
With Privy(@privy_io ) + Solana Keychain MCP + a Solana program + Orquestra MCP (@orquestradev ), all AI systems are getting closer to having 100% access to Solana.
I released the Solana Keychain MCP today. It’s still in testing, but you can already try it with your own devnet programs.

Let's be clear about what @DriftProtocol did:
✗ Cooperated without proper vetting
✗ Weeks of silence on a security issue
✗ No apology to users whose funds were at risk
✗ Released a nothing burger "interim update"
But @cindyleowtt and @davijlu never miss a conference panel. Never miss a chance to call themselves the Hyperliquid of Solana.
A protocol is only as trustworthy as how it behaves in its worst moments.
This is Drift's worst moment. Now you know.
From @cindyleowtt ( She deleted that tweet )
"Trust is built during crisis moments"
Big LOSE for @solana Defi Summer, she destroyed the ecosystem trust.
The jury of @cursor_ai Ankara Hackathon
We are so lucky to have your support 🫡
Let's find the next big thing together
Cursor Ankara Hackathon: Blockchain Edition 🤘
The first @cursor_ai Blockchain Hackathon is tomorrow, in Ankara
We're so thankful for our mentors who're going to guide our participants to build in limited time
