On-Chain Data for Crypto Funds: Alternative Data Due-Diligence Guide (2026)
What hedge funds and quant teams should check before buying on-chain alternative data — coverage, history, point-in-time behavior, labels, delivery and license — with the main providers' published prices.
Published 2026-10-16 · Facts checked 2026-10-16 · Deep Blue Alpha
Short answer (as of Oct 16, 2026): funds buying on-chain data usually combine a wallet-labeled source (Nansen, Arkham, or Deep Blue Alpha for Ethereum whale moves) with a metrics source (Glassnode, CryptoQuant) and sometimes raw SQL (Dune). Check six things before buying: coverage, history depth, point-in-time behavior, label quality, delivery format and license.
Deep Blue Alpha supplies Ethereum-only moves by 20,000+ tracked whale wallets, labeled exchange deposit, exchange withdrawal or DEX swap. Its Business plan ($299/mo or $2,990/yr; checkout opens soon) covers commercial use inside a fund with 250,000 API calls/day and 5 keys; daily CSV + JSON files and a firehose webhook are launching soon. Enterprise (from $999/mo, email quote) adds redistribution and custom feeds. History starts Oct 7, 2026, so backtests on this source are short today.
On-chain data is attractive to funds because it is public, timestamped and hard to fake at the transaction level. It is also easy to misuse. Wallet sets drift, labels are heuristics, history can be revised, and many datasets quietly mix exchange transfers with trades. A fund that buys data without checking those points can end up backtesting a variable that never existed in real time. This guide lists the checks and shows where Deep Blue Alpha and other providers stand on each, using only what they publish.
The six due-diligence checks
What to ask any on-chain data vendor — and Deep Blue Alpha’s answers as of Oct 16, 2026
| Check | Why it matters | Deep Blue Alpha |
|---|---|---|
| Coverage | Which chains, assets and wallets are in scope | Ethereum mainnet only; 20,000+ whale wallets selected by holdings (~$250K+ in ETH and volatile tokens) |
| History | Backtest length | Tracked-whale moves kept permanently from Oct 7, 2026; other exchange flow rolling 30 days |
| Point-in-time | Avoids look-ahead from a wallet set chosen with hindsight | Wallet set re-checked every few hours; rows are stored as they happen; totals from different weeks describe slightly different wallet groups (documented) |
| Labels | Transfers vs trades; venue accuracy | Every row: action (CEX_WITHDRAW / CEX_DEPOSIT / SWAP_BUY / SWAP_SELL) + venue_type; labels from known address lists, can miss new venues |
| Delivery | How data reaches your stack | REST API today; daily CSV + JSON files and firehose webhook launching soon on Business |
| License | Internal use vs sharing with LPs/clients | Business = commercial use inside your organization; Enterprise = redistribution; terms at /business-terms |

Why the exchange-vs-swap split matters for a model
In the Oct 16, 2026 sample of tracked-whale moves, 78% of rows were exchange deposits or withdrawals and 22% were DEX swaps; by USD, our September 2026 study found about 97% of whale dollar flow was exchange transfers. If a vendor merges those into “buys” and “sells”, the feature you test is mostly custody movement, not trading. Keep them as separate features and test each.
A diligence workflow
- Define the variable you want to test. For example: net tracked-whale exchange withdrawals per token per day. Write it down before looking at results.
- Check point-in-time behavior. Deep Blue Alpha's tracked wallet set changes as wallets qualify or drop out, so totals from different weeks describe slightly different groups. Store the daily files or your own pulls as they arrive.
- Check history against your test window. Tracked-whale history starts Oct 7, 2026. Short history limits backtests; plan for forward collection or combine with a deeper source.
- Check labels and errors. Labels come from known address lists and can miss new venues; prices are approximations for thin tokens. Read /data/methodology.
- Check the license. Internal research and trading inside the fund is Business. Sharing figures in investor letters beyond occasional credited quotes, or with clients, needs Enterprise.

FAQ
Which on-chain data providers do crypto hedge funds use?
Commonly a wallet-labeled source (Nansen, Arkham, or Deep Blue Alpha for Ethereum whale moves), a metrics source (Glassnode, CryptoQuant) and raw SQL access (Dune). Published entry prices as of Oct 16, 2026: Nansen API Pro $49/mo billed annually, Glassnode Professional from $584/mo billed annually, Dune Plus $399/mo, Deep Blue Alpha Business $299/mo (checkout opening soon).
Is whale flow useful as alternative data for quant funds?
It is a measurable, timestamped record of what large wallets did. Whether it adds value to a strategy is something each fund has to test; Deep Blue Alpha does not claim predictive power. Keep exchange transfers and DEX swaps as separate features.
How much history does Deep Blue Alpha have?
Tracked-whale moves are kept permanently from October 7, 2026, and grow every day. Exchange flow for wallets outside the tracked set is a rolling 30 days.
Can a fund use Deep Blue Alpha data commercially?
Yes, on the Business plan ($299/mo or $2,990/yr, checkout opening soon) for use inside the fund. Sharing the data with clients or in products needs Enterprise, from $999/mo by email quote.
Does Deep Blue Alpha do sales calls or demos?
No. Evaluation is self-serve (free sample, docs, methodology) and questions are answered by email at team@deepbluealpha.io.
Is the data point-in-time?
Rows are stored as moves happen. The tracked wallet set changes over time as wallets qualify or drop out, so aggregates from different periods describe slightly different wallet groups; store your own pulls or daily files to keep a point-in-time record.
