Read the terms at https://arbitrum.foundation/grants. The Audit Program subsidizes security reviews for Arbitrum apps close to launch, and ArbiFuel sponsors users' gas; ArbiFuel approved 19 of 112 applicants in H1 2026. Use your own Arbitrum deployment, or help a team you serve attach its exported folder: scope, invariants, coverage and deployment plan. Approval is never guaranteed.
Read the wishlist at https://www.bnbchain.org/en/grants, then apply at https://forms.monday.com/forms/0469580c0e412266a888526a38b114a0?r=euc1 under dev tools and infrastructure. They fund open source tools or apps that benefit BNB Chain and show technical depth, up to $200,000, with two review rounds and milestones set on a call. Open sourcing the explanation templates makes the case stronger. Avalanche Team1 Builder Grants were reported in the press with mini grants up to $10,000, but the official apply page was not verified, so confirm it with Avalanche before you apply. Linea has no builder grant program we could confirm. Nothing is guaranteed.
Read the wishlist and RFPs at https://esp.ethereum.foundation/applicants. ESP funds open source, non commercial tooling that matches a listed item or RFP; general open applications were paused in 2025. Apply only for an open source part, such as the plain-words template library.
Teams scanned, findings explained, fixes confirmed by rescan, folders exported, and what auditors said about them.

Leave an email and we nudge you at 24 and 72 hours with your next move. Optional.
Or to keep this voyage on your profile.
A project-in-a-box: contracts, site, docs and impact metrics shaped for grant applications.
Show funders exactly what their grant built, milestone by milestone, with proof attached.
Every commit, deploy, and demo you ship becomes a signed, timestamped builder diary.
