Mission

Create a consumer or social application that leverages the Zerion API.

Hackathon Track Scope

Zerion API offers one of the most comprehensive onchain data stacks available, across EVM + Solana, giving you instant access to:

• Real-time Portfolio & PnL — balances, positions, profit & loss

• Transactions & History — decoded swaps, transfers, approvals, even bundled txs

• Charts & Market Data — price charts, asset metadata, token discovery

• Webhooks & Notifications — address activity, transfers, contract interactions

This lets you build anything from social trading apps and portfolio trackers to onchain feeds, alerts, or discovery platforms, without running your own nodes or indexers.

Here are some ideas to get your wheels turning, but feel free to think outside the box:

• Social features: How can you use onchain data to create new social experiences or connections?

• Portfolio management tools: Can you build a new way for users to visualize or interact with their assets?

• Discovery platforms: Help users find new tokens, NFTs, or DeFi protocols.

• Personalized insights: Use wallet activity to provide unique insights or recommendations to users.
