Summary
Pulls live token prices directly from Base chain DEX pools using ethers.js to read Uniswap V2, Uniswap V3, and Aerodrome contracts. You get seven tools covering current prices, historical data from swap events, volatility calculations, liquidity depth, price impact estimates, cross-DEX arbitrage comparison, and full market summaries. No external APIs or keys needed since everything runs on pure on-chain reads against Base mainnet. Useful when you need real-time DeFi pricing without depending on third-party data providers or want to compare prices across multiple DEXes for arbitrage opportunities. Point it at a custom RPC if you need higher rate limits.
