Crypto hackathons open or coming, the soonest to close first and the ones you have to attend at the end, each with $1K or more in prizes where the prize is given.
Build perpetuals or prediction market products on Solana within one week. A $1,000 bounty requires the PREDICT pm-AMM as a core part of the product, judged mostly on real on-chain traction.
Build any app (DeFi, gaming, social, DePIN or other) deployed on an Arbitrum chain such as Arbitrum One, Sepolia or Robinhood Chain. At least one top prize is reserved for Robinhood Chain, and USDG integration gets extra consideration. Existing projects can enter.
Build on Solana for AI agents that pay onchain: agents buying data, compute and services, wallets and spending controls for them, or tooling for merchants and APIs to accept agent payments (x402, Payment Channels). Not yet funded or scheduled.
Build on Solana for tokenized real-world assets other than stocks: issuance and compliance rails, secondary markets, collateral use, yield products, or consumer ways to hold and move them. Not yet funded or scheduled.
Listed by hand, each from the programme's own page, and read again every week: last on 30 Oct 2026. Check the page before you apply.
Milestone grants for public goods such as open-source work. Mainly commercial projects are pointed to its convertible grants, and its RFP board lists ideas it wants funded.
Quick grants for early-stage Solana builders in emerging markets, Southeast Asia among them. Listed on the Solana Foundation's funding page.
For open-source developers across tools and infrastructure, DeFi, GameFi, AI and social. Check its wishlist first, then two rounds: a technical review, then milestones and the amount.
The Foundation's milestone grants for building on Arbitrum chains. The page also lists ArbiFuel gas sponsorship for early-stage teams and audit subsidies, both marked active. Robinhood Chain is not mentioned there.
For protocols making USDG their main stablecoin, with incentives from $1M in stablecoin balances. The pool goes to the first ten teams to reach $10M of USDG. For a live product, not a first build.
Grants against its Wishlist of gaps in the ecosystem and its narrower RFPs, with one application per item. Most applications are reviewed in 3 to 6 weeks.
An accelerator with a demo day. This is an investment rather than a grant, and Base lists its Ecosystem Fund for pre-seed and seed in the same place.
You have to be there, and usually build there.
Build solutions in one of four tracks: Cosmo-Localism, PayFi & RWA, Longevity, or Privacy & Data Sovereignty, for builders from Web3, AI and Longevity. Teams of 1 to 4, free to register.
Read twice a day from ETHGlobal, the Solana Foundation, HackQuest, Devfolio, Devpost and Colosseum's blog, last 8 hours ago. DoraHacks lists more, and is not read here. The short notes are written by Claude from each hackathon's own page and can be wrong, so read the page before you build.
