Monitoring New Uniswap V4 Pools on Robinhood Chain with JSON-RPC

Summary

This hands-on guide builds a read-only radar for newly initialized Uniswap V4 pools on Robinhood Chain. It explains that V4 pools are managed through a shared PoolManager contract, so a monitor can query chain logs for its Initialize event rather than search for individual pool contracts. Using standard EVM JSON-RPC through FMZ, the program checks network connectivity, calculates the event topic, requests logs over block ranges, and decodes pool identifiers, currencies, fees, tick spacing, and hook addresses. It also distinguishes native ETH from WETH and queries ERC-20 token names, symbols, and decimals when available.

The article reports that the monitor captured real pool events and describes a dashboard for network state, scan counts, and recently found pools. It discusses provider rate limits and splitting log queries into smaller ranges. The tool only discovers pools; initialization does not prove that a pool has liquidity or presents a viable trade. The author stresses that liquidity, token contract risk, and subsequent trading activity need separate analysis. RPC reliability, malformed token metadata, and the gap between virtual monitoring and execution also limit what this prototype establishes.

Key ideas

• Uniswap V4 pool initialization can be monitored by filtering PoolManager logs for the Initialize event.
• Standard EVM JSON-RPC methods support connecting, querying block logs, and retrieving token metadata.
• The event contains pool and asset details, while native ETH and WETH require separate recognition.
• The guide reports successful event capture and demonstrates a dashboard, while noting that RPC providers impose different query limits.
• A newly initialized pool may lack liquidity or be unsafe, so discovery alone is not a trade signal.
