About

In the emerging agent economy, ERC-8004 gives autonomous agents verifiable on-chain identity, reputation, and validation so others can discover and trust them at scale. Google BigQuery’s public Ethereum dataset provides raw data in near real time with zero infrastructure or rate limits. This enables hackers to build the search, ranking, and analytics layer for any smart contract using only SQL and a lightweight frontend.

Prizes

🤖 Best On-Chain Agent Economy Application ⸺ $5,000

Create tools that help applications, agents, or other composable integrations rank agents by feedback and reputation. Your goal is to highlight which ones support x402 payments, creating a one-stop place to discover trustworthy, payable agents in the emerging agent economy.

Ideas for your submission:

Big Data meets ERC-8004: Build a real-time or historical explorer for ERC-8004 Identity, Reputation, or Validation registries.
Advanced Analytics: Write SQL to pull ERC-8004 events, compute reputation scores, detect trends, or build activity heatmaps.
x402 Integration: Flag agents with x402 payment metadata by joining on-chain data to provide transparency to the x402 ecosystem.
Search & Filters: Build a natural language or filter UI over agent URIs, metadata, and reputation.

Qualification Requirements

Projects must use Google BigQuery as the core for querying raw Ethereum mainnet ERC-8004 data.
Projects must utilize the specific Ethereum Foundation ERC-8004 reputation & validation addresses.
The BigQuery backend should be paired with a lightweight frontend or visualization library (e.g., Streamlit, Cloud Run Next.js, Looker Studio).
