How to read the 0x3a31e1704738b6fc5af095f507ba61c1f6f129ee pool activity on Arbitrum

The 0x3a31e1704738b6fc5af095f507ba61c1f6f129ee liquidity pool page on Arbitrum provides comprehensive analytics including slippage analysis with interactive charts, real-time pool activity tracking, and detailed metrics. This page helps you understand price impact, liquidity depth, and trading dynamics for this specific pool.

  • Slippage Analysis. The page features interactive slippage charts showing price impact and minimum output amounts at different trade sizes. You can switch between trading directions (A→B or B→A) using the swap button in the header. The first chart displays price impact with an inverted slippage scale (higher slippage at the bottom), while the second chart shows minimum output amounts. Below the charts, a detailed slippage table lists all available slippage tiers with maximum tradeable amounts, helping you understand liquidity depth at different price impact levels.
  • Pool Metrics Cards. Key metrics are displayed at the top: current price (showing the exchange rate between tokens), minimum slippage (with maximum tradeable amount at that slippage), total liquidity (available in both tokens), and slippage tiers count (showing the range of available slippage levels). These metrics update based on the selected trading direction.
  • Pool Activity (real-time). The table shows a real-time stream of pool events including swaps, liquidity additions (positive changes) and removals (negative changes) for both base and quote tokens. Each row displays execution time, trading pair, token amount changes (with color coding: green for increases, red for decreases), USD values for both tokens, transaction hash and action type. This helps you see exactly how the pool balance changes over time, whether liquidity is being added or removed, and how frequently the pool is being used for swaps.
  • Bitquery APIs & streams. The "Get API" buttons below the charts and table open the exact Bitquery GraphQL queries powering these views, and you can access real-time subscription queries. You can plug these directly into your own pool monitoring systems, liquidity tracking dashboards or DeFi analytics tools, and customize fields, filters, networks and time ranges to build a tailored view of 0x3a31e1704738b6fc5af095f507ba61c1f6f129ee pool activity.
