About Crypto ETF

Meet the Founder

Vadim Semenko

Founder & Creator

Vadim is a software engineer and crypto enthusiast with deep expertise in data analysis, market analytics and data systems. He built Crypto ETF to give investors and analysts transparent daily access to crypto ETF flow data — filling a gap in the market. With a background in full-stack development and fintech across multiple production systems, Vadim has dedicated Crypto ETF to three core principles: simplicity, accuracy and reliability. He monitors the platform daily and keeps improving both the data pipeline and the product based on feedback from investors, analysts and developers.

Our Mission

We believe that transparent data on crypto ETF flows empowers better investment decisions. Institutional flows reflect capital decisions from professional investors and reveal market sentiment that price action alone cannot show. Crypto ETF makes this data accessible to everyone — whether you're a day trader, portfolio manager or analyst. Unlike many data providers that gate insights behind expensive subscriptions, Crypto ETF offers a free daily dashboard alongside a developer API, because we believe market transparency benefits the entire ecosystem.

Data & Methodology

We track spot ETFs from major issuers including BlackRock (IBIT), Fidelity (FBTC), Grayscale (GBTC, ETHE), Bitwise, VanEck, ARK 21Shares, Canary and others — covering all 16 assets, from Bitcoin, Ethereum, Solana, XRP and Hyperliquid to Dogecoin, Chainlink, Avalanche, Hedera, Litecoin, BNB, Polkadot, Sui, NEAR, Tron and Zcash. Each trading day's flows are published the next morning (T+1).

All data is provided for informational purposes only and is not investment advice. Past performance does not guarantee future results. Crypto investments carry significant risk. Always do your own research and consult a financial advisor before making investment decisions.

The Platform

Crypto ETF launched in 2024 as a response to the lack of a single, reliable source for crypto ETF flow data. Crypto ETF aggregates this data into a single, clean interface updated every trading day.

Today the platform tracks more than $120 billion in assets across 50+ funds spanning 16 assets, from Bitcoin and Ethereum to Dogecoin, Chainlink and Sui. It serves individual investors following daily flows, portfolio managers tracking institutional sentiment, developers pulling the data through the REST API and MCP server, and researchers studying how ETF flows relate to crypto prices.

The platform also offers a proprietary sentiment indicator—CEFI (Crypto ETF Flow Index)—that aggregates net flows across all tracked assets into a 0–100 score. CEFI provides a flow-only view of institutional sentiment, complementing price-based indicators like the Bitcoin Fear and Greed Index.
