Introduction

The DeFiStream API provides programmatic access to decoded blockchain events across multiple chains and exchanges. Use this API to:

• Track token transfers (EVM ERC20, EVM native tokens, Tron TRC20, Tron TRX, Bitcoin BTC)
• Monitor lending protocol activity (AAVE deposits, borrows, liquidations)
• Analyze DEX trading data (Uniswap swaps, liquidity events)
• Track staking flows (Lido deposits and withdrawals)
• Access exchange data from Binance and Hyperliquid (trades, OHLCV candles, open interest, funding rates, book depth, long/short ratios)
• Aggregate events into time or block buckets for volume charts and trend analysis
