# ✨ March 30, 2026 - Base Pulse Perf Improvements, New Positions Fields & New Search Filters

> 50-100ms head lag on Base chain pools, new totalFeesPaidUSD field in positions, and bundler percentage filtering in search

**TL;DR**: Base chain pools now detected in 50-100ms on Pulse stream, new fee tracking field in all position endpoints, and advanced bundler filtering in token search.

## Base Chain Pulse Performance

Pulse stream now detects new liquidity pools on Base chain with 50-100ms latency. Faster pool discovery for traders targeting early entries.

## New Positions Fields

All position endpoints now return `totalFeesPaidUSD` field for complete P\&L calculations. Previously missing in some position query responses.

## New Search Filters

Token search endpoint supports `bundlers_holdings_percentage` filter. Users can filter tokens by bundler concentration for deeper market analysis.

## Wallet Activity Improvements

Better swap detection accuracy in wallet feeds. Token pairs are now correctly identified by analyzing actual transfers rather than native fee transactions.

## Data Quality Automation

Background balance audit system for holder position data. Automatically detects and corrects stale balance records without manual intervention.

## Stream Stability

Improved WebSocket connection management with automatic cleanup of disconnected clients. Reduced memory usage in high-frequency trading data streams.
