If you searched "Nansen vs Fensory" or "Arkham vs Fensory," you probably landed here expecting a feature-by-feature matchup. There isn't one to make honestly. Nansen and Arkham Intelligence are on-chain analytics and wallet-intelligence platforms: their job is to help you see and label what's happening on-chain. Fensory is a non-custodial allocation platform: its job is to help you act on-chain, whether that's holding tokenized equities, earning DeFi yield, trading perps, or letting an AI agent trade on your behalf inside limits you set.
Worth noting up front, since it's easy to miss: both companies have started building trading features of their own in the last two years. Nansen added an in-app AI trading agent in early 2026, and Arkham operates a separate centralized exchange business. We cover exactly what those are and how they differ from Fensory below, because glossing over it would be inaccurate. But neither company's core identity or specialty has moved from analytics. That's still what people search "Nansen" or "Arkham" to find, and it's still what they're best at.
What Nansen and Arkham actually do
Nansen is an on-chain analytics platform built around wallet labeling. It tags large numbers of wallets (Nansen cites over 500 million labeled addresses) by behavior, historical PnL, and holding patterns, then surfaces that labeling in dashboards like Token God Mode and Wallet Profiler so users can see what "Smart Money" wallets, funds, and known entities are buying, selling, and holding. In January 2026, Nansen added an AI-powered trading agent: users chat with it in natural language, it surfaces a suggested trade, and execution requires explicit per-trade confirmation through an embedded wallet described by Nansen as non-custodial and secured via Privy. At launch this covered spot swaps on Solana and Base; Nansen later added Hyperliquid perps trading inside the same interface, including crypto perps and a set of tokenized single-stock and index perps (NVDA, TSLA, AAPL, and a licensed S&P 500 perpetual) that trade on Hyperliquid itself. So the trading layer exists, but it's a conversational execution feature bolted onto an analytics dashboard, scoped to specific venues and chains, not a general multi-chain allocation platform.
Arkham Intelligence is a blockchain intelligence platform focused on deanonymizing on-chain activity: linking wallet addresses to real-world entities (exchanges, funds, institutions, individuals) and visualizing the relationships between them. This is used heavily for research, compliance, and investigative work, including tracing hacks, fraud, and ransomware flows. Separately, the same company operates Arkham Exchange, a centralized cryptocurrency exchange launched in stages from late 2024. Arkham Exchange is custodial in the traditional CEX sense: users complete KYC, deposit funds into accounts the exchange controls, and trade spot and perpetual markets there, with Arkham publishing proof-of-reserves data as a transparency measure. It is a distinct product from the Arkham Intelligence analytics platform, run under the same company but with a different account system and a fundamentally different custody model.
Both are genuinely good at what they were built for. If you want to know which wallets are accumulating a token, who's behind an address, or how funds moved through a hack, Nansen's labeling and Arkham's entity graph are purpose-built for that in a way a trading platform isn't trying to replicate.
What Fensory actually does
Fensory is a non-custodial platform for composable finance. "Non-custodial" here has a specific meaning: when you hold a tokenized asset or open a position through Fensory, it settles to your own wallet. Fensory never takes custody of it.
Four things are live today: 101 tokenized US equities sourced from two issuers, Ondo and xStocks; DeFi yield aggregated across 28 protocols and 330+ products; a live perps terminal spanning 250+ markets across crypto, stock indices, FX, and commodities; and MCP agentic trading, connecting Claude, ChatGPT, Cursor, Codex, Hermes, and OpenClaw over mcp.fensory.com, with a user-set per-trade cap and market permissions, no ability for the agent to withdraw or transfer funds, and instantly revocable access. Fensory operates across Ethereum, Solana, and BNB Chain.
The different jobs, side by side
| Category | Nansen / Arkham | Fensory |
|---|---|---|
| Core job | See and label on-chain activity: wallet behavior, entity identity, fund flows | Hold and trade on-chain assets: tokenized equities, DeFi yield, perps |
| Primary output | Dashboards, wallet labels, entity graphs, alerts | Positions and holdings settled to the user's own wallet |
| Trading, if any | Nansen: AI agent bolted onto the analytics dashboard, Solana/Base spot plus Hyperliquid perps, per-trade confirmation. Arkham: a separate custodial exchange (Arkham Exchange), distinct from the analytics platform | Native, non-custodial trading and allocation across equities, DeFi yield, and perps in one platform |
| Custody model | Nansen's trading wallet: non-custodial, embedded. Arkham Exchange: custodial, KYC'd, deposits held by the exchange | Non-custodial throughout, assets settle to the user's own wallet |
| Agent access | Single in-house AI agent (Nansen only), scoped to Nansen's own venues | MCP access for multiple third-party AI assistants, with user-set per-trade caps and revocable access |
| Asset breadth | Wallet and token intelligence across many chains; trading (where it exists) limited to specific venues | Tokenized equities from two issuers, DeFi yield across 28 protocols, and 250+ perps markets on Ethereum, Solana, and BNB Chain |
Use both, here's how they fit together
These aren't mutually exclusive tools, and plenty of people will reasonably want both. A workable split: use Nansen or Arkham to do the research, which wallets are accumulating a token, who's behind a large transfer, whether an address has a track record worth following, or what smart money is rotating into. Use Fensory to act on that research: buy the tokenized equity, allocate into a DeFi yield product, open the perps position, or hand a scoped, capped mandate to an AI agent to execute within limits you define.
If you're already trading through Nansen's own agent or holding funds on Arkham Exchange, it's worth being clear-eyed about the custody trade-off in each case: Nansen's embedded wallet is non-custodial, but Arkham Exchange holds your funds the way any centralized exchange does. Fensory's model, across equities, yield, and perps alike, keeps assets in the user's own wallet throughout.
FAQ
Is Nansen a trading platform now, or still just analytics?
Nansen's foundation and primary specialty is on-chain analytics and wallet labeling. As of early 2026 it also offers an AI-powered trading agent for spot swaps on Solana and Base and Hyperliquid perps, executed through an embedded non-custodial wallet with per-trade confirmation. It's a real feature, but it sits on top of the analytics product rather than replacing it.
Does Arkham Intelligence hold my funds?
The Arkham Intelligence analytics platform itself doesn't hold funds, it's a read-only research and labeling tool. Arkham Exchange, a separate custodial product from the same company, does hold user funds the way any centralized exchange does, once you deposit into it. Those are two different products with two different custody models.
Is Fensory an analytics platform too?
No. Fensory doesn't offer wallet labeling, entity deanonymization, or smart money tracking. It's an allocation platform: tokenized equities, DeFi yield aggregation, a perps terminal, and MCP agentic trading, all non-custodial.
