Building AI-native on Solana

Every hour spent rebuilding something Helius or Privy already ships is an hour not spent on what judges actually score. Four weeks is enough for exactly one strong use case, and only if the plumbing is bought rather than built.

Crypto World's Fair is the first Colosseum competition open to every blockchain ecosystem, so this is a real decision now rather than a given. Prize tracks are organised per ecosystem (Solana, Tempo, Hyperliquid, Zcash, Ethereum L1, Base, Arbitrum and Robinhood Chain), and every submission also competes in a general pool across all of them.

So the honest version: pick the chain your product actually needs. If the answer is genuinely another ecosystem (you need its liquidity, its users, its execution model), build there and compete for the prizes. If the answer is a coin flip, Solana is the one with money behind it after the competition ends, and it's the one we can help you with. Everything below is Solana-specific for that reason.

• Many strong entries will use more than one chain under the hood. Colosseum said as much in the announcement. Abstracting that away from users is a feature, not a hedge.
• Whatever you pick, judges ask why this chain. Have a real answer that names a property of the infrastructure, not a preference.

• solana.new: scaffolds plus the AI skills and MCP servers that let an agent write Solana code that compiles.
• Solana developer templates: working starting points for token, program, client and mobile projects.
• Solana Playground: browser-based build, test and deploy when you don't want to lose a morning to local toolchain setup.

The pieces below are what production Solana teams actually run. Picking from this list isn't cutting corners; it's the same decision the companies you're competing against already made.

• RPC and transaction landing: Helius, Triton, Jito bundles. Don't ship on a public endpoint; dropped transactions during a demo are unrecoverable.
• Wallet authentication: Privy. Email and social login onto a real wallet, which is usually the difference between a demo people finish and one they abandon.
• Swaps and routing: Jupiter Ultra.
• Multisig and smart accounts: Squads Protocol and their APIs.
• Rollups and compression: Magicblock, Light Protocol.
• Prices and oracles: Pyth, Switchboard.

• Solana transaction guide: why yours isn't landing↗
• Solana developer documentation↗
• Solana Stack Exchange: when the agent and the docs both fail you↗

If you're arriving from another ecosystem, don't read the whole documentation set. Take one guided path end to end, then build.

Saying your product uses AI isn't a differentiator in 2026; every submission says it. AI-native means the core loop is impossible without a model: the agent is the product, not a feature bolted onto a dashboard.

1. 01Remove the model. Does the product still exist? If yes, you have an AI feature, not an AI-native product.
2. 02Remove Solana. Does it still work on a normal database? If yes, judges will say so before you do.
3. 03If both removals break it, you have found the thing worth building for four weeks.

The places the two genuinely need each other are agentic payments, autonomous onchain execution, and verifiable memory or provenance. Everything else tends to be a web app with a chat box.

• Install the Solana skills for your coding agent from solana.new before you write anything. An agent without them will confidently produce Solana code that doesn't compile.
• Run Colosseum Copilot alongside them for competitive context, not just code.
• Review what the agent writes against the transaction guide. Programs that work on devnet and fail under real load are a common and very visible way to lose a demo.
