If you are shipping before Oct 12, this is the stack that actually matters 💡 not a random GitHub dump.
What a serious builder should lock in first 🤔
1. Pick the track, then use first-party docs
Official quick start + core docs for that chain. Do not mix last-year tutorials with this season’s SDK.
2. Current client, not the legacy one
On Solana that means @solana/kit (and knowing where old web3.js still leaks in).
Same rule on EVM tracks: current viem / Foundry / official L2 SDKs, not copy-paste from 2023.
3. A real environment
CLI + local repo. Browser playgrounds (Solana Playground, Remix-style tools) are fine for the first tx. Secrets and durable work leave the browser.
4. Wallet + onboarding before UI polish
Phantom Connect, Privy, Wallet Standard / injected wallets. Decide custody and email-onboarding *before* you design the homepage.
5. RPC with a free prototype tier
Kit lists Helius, RPC Fast, FluxRPC, Triton, QuickNode on Solana. Get a working endpoint on day one. Heavy methods and gRPC usually need a paid plan ,plan that.
6. Test at the right layer
Fast in-process tests first (LiteSVM / Mollusk on Solana), then a local validator-compatible network (Surfpool). Security drills: signer, ownership, init, PDA/CPI failure modes. Same idea on EVM: unit tests, then fork tests.
7. Program path
Anchor for most Solana programs; Pinocchio only if you have a reason. Codama for typed clients. On EVM tracks: Foundry + audited patterns, not a custom compiler adventure in week 2
8. Only add product rails you will demo
Tokens / Token-2022 + ACL, payments, Blinks/Actions, mobile, games, agents, privacy. The kit has them. Judges reward a working product, not a checklist.
9. If you code with an agent
Install the official skill so the model reads the same kit:
npx skills add ColosseumOrg/colosseum-resources
10. Founder layer, not only code
Company formation, US banking, USDC treasury (Stablecorp perks are in the kit). A hackathon winner with no entity still has homework.
Practical order for a 3-week sprint
Day 1: track + official quick start + RPC + wallet
Day 2–3: scaffold + first on-chain write
Week 1: core loop + tests
Week 2: payments / tokens only if the product needs them
Week 3: demo path, security pass, submission
Submissions due 12 Oct 2026
Time to build 💪
