The Arbitrum Foundation Grant Program provides milestone-based funding to teams that drive adoption of Arbitrum chains, strengthen technical infrastructure and build sustainable communities. The current phase is open to two categories: dApps building on Arbitrum One, Nova, Orbit or Stylus, and Infrastructure and Tools that other builders depend on. Applications are accepted on a rolling basis with no fixed deadline, and funding is released against agreed milestones rather than as a single upfront payment.
