Why raw blockchain data isn’t enough: most tools give you addresses and hex logs, which means hours of manual decoding to understand what actually happened. Defeyes enriches events automatically—extracting the real origin wallet, labeling protocols, and shipping clean structured JSON/CSV.

RAW BLOCKCHAIN DEFEYES ENRICHED API
❌ Just "transaction" ✅ BORROW, SWAP, FLASH_LOAN
❌ Callback address ✅ Origin wallet extracted
❌ Contract addresses ✅ "Aave V3", "CoW Protocol"
❌ Hex, raw logs ✅ Human-readable JSON/CSV
❌ Hidden yield rates ✅ Historical APY Tracking (Aave V3)

How it works

Defeyes turns raw Arbitrum transactions into clean, labeled DeFi events with origin wallets and protocol context.

What does “enrichment” mean?

We decode low-level transaction traces into high-level actions (e.g., FLASH_LOAN, SWAP, BORROW) and attach context like protocol labels, human-readable fields, and real-time Yield (APY) intelligence.

What is "Yield Intelligence" (APY)?

Defeyes captures the Live APY (Annual Percentage Yield) at the exact second a transaction occurs. This tells you the economic incentive (the "Why") that drove a user to act, helping you track yield-chasing behavior and market shifts.

How do you find the real user (origin wallet)?

Many transactions execute via callbacks/routers. We link the onchain execution back to the initiating wallet so analytics reflect the real actor—not just an intermediary contract.

How “real-time” is it?

New events are continuously ingested and enriched, then exposed via API and optional webhooks so you can trigger alerts and workflows quickly.

What formats can I export?

Use JSON for structured pipelines or CSV for quick analysis. The free tier limits request volume and export size; Pro unlocks full dataset + commercial rights.
