Nansen vs Arkham vs DeBank: analytics, execution and the agent account
The old comparison treated Nansen and Arkham as analytics tools and Fensory as the place where an agent acts. That is no longer accurate. Nansen now combines wallet intelligence with user-confirmed spot and Hyperliquid perpetual futures trading. Arkham has a separate integrated Exchange. DeBank remains the clearest read-only tracker in the group.
Fensory solves a narrower execution problem. It gives a connected assistant account, market and order tools plus limits enforced on the account. It does not replace the entity attribution, wallet labelling or protocol-level portfolio analysis in the other products. The useful question is which layer the workflow is missing.
Every cell was checked against first-party documentation, governing terms or regulator material on 2026-10-18, never on a directory listing or another comparison. Fensory publishes this page and appears in the table.
Side by side
| Product | Who holds the funds | What stops a bad order | What it trades | Where you can open it |
|---|---|---|---|---|
| Nansen Portfolio and TradingWallet intelligence plus user-confirmed trading | Tracked external wallets stay where they are. Trading uses a Privy-powered embedded wallet that Nansen describes as non-custodial. | Quote review, slippage settings, MFA, explicit confirmation and take-profit or stop-loss orders. No configurable account-level exposure cap is documented. | Multi-network wallet analytics, spot crypto and Hyperliquid perpetual futures. | Perpetual futures are unavailable in the United States and United Kingdom. Other product restrictions also apply. |
| Arkham Intelligence and ExchangeEntity attribution plus a separate exchange | Tracking a public address is non-custodial. The current official material reviewed does not clearly explain the Exchange custody or key-management model. | Intelligence alerts, plus exchange market, limit and take-profit or stop-loss orders. No cross-product account exposure limit is documented. | Multi-chain wallet intelligence, crypto spot, perpetual futures and decentralized Solana token trading. | The intelligence service primarily excludes sanctioned users. Exchange onboarding excludes the United States and varies by jurisdiction. |
| DeBankRead-only DeFi portfolio visibility | DeBank does not create or custody the wallet. Its terms say it cannot perform transactions or send transaction messages for the user. | Health factors, approval visibility and transaction explanations. No autonomous order or account policy is documented. | Ethereum and EVM wallet and DeFi positions across supported chains and protocols. | No complete country exclusion list is published. Users remain responsible for local-law compliance. |
| FensoryOursAgent-facing account and market execution | You. Tokens settle to a wallet you control, perp margin sits at the venue | a kill-switch, an access expiry, a market allow-list and a per-order cap, all enforced on the account. An order above the cap is rejected rather than trimmed | MCP: Hyperliquid spot and perpetual futures. App: tokenized US equities and treasuries, and gold | Not available to US persons |
Every row uses the same custody, control, asset and geography fields so the comparison stays aligned.

The operating trade-off in concrete terms, from first setup to the markets the agent can reach.
| Decision | Nansen, Arkham and DeBank | Fensory |
|---|---|---|
| Best-known strength | Nansen: labelled wallets; Arkham: entity attribution; DeBank: protocol positions | Agent account and order controls |
| Execution model | Nansen confirms each trade; Arkham uses a separate Exchange; DeBank leaves signing to the wallet | Connected client calls account tools under current account settings |
| Research depth | Deep wallet and portfolio analysis | Market and account data needed for the supported trading workflow |
| Policy layer | Product-specific confirmations, alerts and order options | Order cap, market allow-list, access expiry and kill-switch |
Where each one is stronger
Specific rather than generous. A comparison that cannot name what the other product does better has not understood it.
Nansen Portfolio and Trading
Nansen has the strongest combined analytics and execution story. Labelled-wallet intelligence, Smart Money signals, portfolio history and alerts sit beside an embedded wallet that can trade spot and Hyperliquid perpetual futures after user review. It is the better choice when the research itself is the product and every proposed order should still pass through a person.
Arkham Intelligence and Exchange
Arkham is strongest at entity attribution. It links addresses to named organizations or people and visualizes flows across those entities, which is a different research problem from tracking one portfolio. A separate Exchange exists for readers who want to remain inside the Arkham ecosystem after the investigation.
DeBank
DeBank is the cleanest read-only portfolio layer here. A public address is enough to see protocol-level lending, staking, liquidity, rewards, debt and approval data without creating a trading account or giving the service signing authority. It is also the easiest product for inspecting a wallet that is not yours.
What connecting actually involves
Nansen Portfolio and Trading
Add public addresses for tracking or use the embedded wallet for trading. Review the quote, slippage and proposed spot or perpetual futures order, then confirm it. The user confirmation is part of the current product shape rather than a backend order cap.
Arkham Intelligence and Exchange
Use the Intelligence Platform for entity, wallet and flow research. Add a public address, wallet connection or exchange API key for portfolio context. Move to the separate Exchange only if its custody, eligibility and current fees have been verified for the intended account.
DeBank
Paste a public address for a read-only view, or connect a wallet for features that need ownership context. DeBank may explain or initiate an action, but the connected wallet supplies authorization and execution.
Fensory
Connect the hosted MCP endpoint through OAuth and configure the account controls in the app. The assistant receives market, account and order tools. Fensory does not supply the labelled-wallet intelligence that makes Nansen and Arkham research products.
Where Fensory differs
Fensory is built around what a connected agent may do on one account. Its market and account reads support execution, while the account checks the configured market, order size, access window and enabled state before a permitted order reaches the venue.
That is less research depth than Nansen or Arkham and less public-wallet breadth than DeBank. The trade is a shorter path from an assistant instruction to an order with trading-specific controls outside the model.
The products can be complementary. A team may use a tracker or intelligence service for research and a separate account for execution. This page does not claim a packaged integration among them.
Which one is for you
You want wallet labels, Smart Money research and confirmed trading together
Nansen. That is the most complete combination of research and execution in this group.
You need to identify entities and trace flows between them
Arkham. Its attribution and visualization layer is the reason to choose it.
You want read-only DeFi portfolio visibility for any public address
DeBank. It does not need custody or execution authority to provide the view.
You already have the research and need an agent-facing execution account
Fensory, if its geography and current market scope fit the workflow.
Questions people ask
- Is Nansen still analytics only?
- No. Nansen now offers spot swaps and Hyperliquid perpetual futures through an embedded wallet. Its current flow asks the user to review and confirm the proposed trade.
- Can Arkham place trades?
- Arkham Exchange is a separate integrated execution product for crypto spot and perpetual futures. The Intelligence Platform itself remains the research and attribution layer.
- Can DeBank trade from my wallet?
- DeBank’s terms say it cannot perform a transaction or send the transaction message for the user. A connected third-party wallet authorizes and executes actions initiated through the interface.
- Does Fensory replace Nansen or Arkham research?
- No. Fensory provides the account, market and order surface for supported trading. It does not provide their depth of entity attribution, wallet labelling or flow analysis.
- Can I combine research from one product with execution in another?
- Yes as a workflow design, provided a person or tested system carries the signal across and validates freshness, market identity and order size. This page does not claim a current direct integration.
How this was put together
The page answers the related wallet-intelligence, portfolio-tracking and execution questions in one comparison. Nansen and Arkham were re-checked on 18 October 2026 because both now have execution products as well as research surfaces.
Nansen facts come from its current Portfolio, Trading, security and pricing documentation. Arkham facts come from the Intelligence Platform, Personal Portfolio and Exchange documentation. DeBank facts come from its terms, paid-feature page and Connect documentation.
Unknown Arkham exchange custody, current fees and API-key permissions are stated as unknown rather than inferred from the Intelligence product. DeBank is not called execution-capable merely because its interface can initiate a wallet action.
Fensory publishes the page and appears last. Each external product receives a specific recommendation for the work it performs better than Fensory.
