Consumer-oriented “killer apps” have the power to define and lead entire industries by solving real user pain points at scale. Think of how ChatGPT made AI accessible to hundreds of millions. Flow is designed for mass adoption and consumer-grade experiences, so we’re looking for the next breakthrough application that can capture the interest of millions (or billions!) of everyday users. This is a very broad bounty and eligible projects include everything from AI Agents and RWA to games and social apps.

Flow Actions (FLIP-338) are a brand-new standard that turn protocol logic into self-contained, reusable onchain building blocks you can call without importing ABIs, reading contract code, or writing brittle glue scripts. Each Action is a trustless workflow with clear metadata, built-in safety checks, atomic execution, and verifiable success criteria—think standardized onchain APIs that plug together like Lego bricks. For AI agents, this means instant discovery of available protocols, safe composition of complex workflows, and full automation without off-chain keepers or MCP servers. This bounty is calling on builders to push the boundaries by creating new connectors to major protocols, chaining cross-protocol workflows, integrating Actions into games, integrating fully onchain agents with actions, or making tools that help others discover and use useful Actions. Whether you’re into DeFi, gaming, or novel automation, this is your chance to shape the future of composability and define how agents interact with Web3.

When building for Walrus, we encourage you to think about two broad directions:

1. Applications that use Walrus storage Focus on an app idea where decentralized storage solves a real pain point. Examples include: hosting for NFTs, Democratized access to AI models or Crowdsourced video streaming.

2. Developer tools for Walrus Build something that helps developers integrate with Walrus more easily. Since Walrus is a chain-agnostic decentralized storage network, there are many opportunities here- SDKs, caching layers, streaming utilities, blob management tools, and more.

Before you dive in: • Browse the Awesome Walrus repo to see what already exists. • Check in with the Walrus team during the hackathon to validate your idea early. • For more inspiration, see our proposal tooling ideas below.
