Onchain intelligence and wallet tracking platform covering more than 500 million labeled addresses
Nansen is an onchain intelligence and trading platform that enriches raw blockchain records with over 500 million labeled addresses. The platform lets traders follow capital flows, monitor whale portfolios, and execute transactions directly from data dashboards.
Founded in 2019 and headquartered in Singapore, Nansen was co-founded by Chief Executive Officer Alex Svanevik alongside Lars Bakke Krogvig and Evgeny Medvedev. The company raised early venture backing from investors including Fabric Ventures and Robot Ventures.
The platform aggregates multi-chain transaction activity and maps transactions to categorized entities such as funds, public figures, exchange reserves, and algorithmic Smart Money cohorts. Users analyze token distribution, track wallet profit and loss, monitor holder dynamics, and set activity alerts. Through an embedded non-custodial wallet powered by Privy, traders execute spot and perpetual contracts directly in web and mobile interfaces. Execution routes through external liquidity aggregators including Jupiter, OKX, and LI.FI. Nansen also provides an AI agent interface, which handles research queries and initiates trades via prompt interactions.
Nansen offers both free access and paid tiers, including an annual Pro membership. Paid subscribers receive larger allowances of Nansen Agent credits, such as 5,000 monthly credits as of October 2026. Trading execution incorporates a loyalty tier system where active traders accumulate points to unlock discounted fee schedules.
The platform has tracked blockchain activity since 2020, scaling its catalog to more than 500 million tagged addresses. In October 2026, Nansen expanded its infrastructure footprint by becoming one of 17 active mainnet operators running the multi-party computation network for NEAR Protocol, alongside rolling out searchable tracking for over 200,000 fomo wallets across Solana and Base.
Trade execution relies on third-party routing infrastructure and decentralized liquidity pools, exposing swaps to slippage and underlying smart contract vulnerabilities. Labeled wallet signals do not eliminate trading risk, as whale movements can reflect internal rebalancing or automated market maker churn rather than market directional conviction.

Nansen pairs deep intelligence from over 500 million labeled wallets with direct trading execution, though tier discounts depend on accumulated points and key analytics require paid plans.
Nansen launched in 2019 out of Singapore and made its name by indexing and labeling raw blockchain data. The platform tracks more than 500 million labeled addresses, categorizing activity into cohorts such as Smart Money, funds, and public figures. Rather than serving strictly as a research tool, the current interface merges onchain discovery with direct spot and perpetual trading across web and mobile applications.
The system excels at surfacing market-moving flows. Users can monitor net capital inflows, track token holder dynamics, and follow individual wallet PnL. Trade execution aggregates liquidity through Jupiter, OKX, and LI.FI. Traders can swap tokens or open derivatives contracts without leaving the data terminal. Embedded non-custodial wallets powered by Privy handle account onboarding, keeping private keys under user control while eliminating manual signing hurdles for every swap. An AI analyst agent lets users research addresses and execute orders directly through conversation.
The main trade-off lies in cost and data segregation. Nansen maintains both a Free tier and a paid Pro plan, with tiered discounts on trading fees tied to trading points. Advanced analytics and higher AI agent credit allowances remain behind the Pro subscription. Users who simply want a passive portfolio tracker without trading features may find the multi-asset execution terminal unnecessarily dense.
Backed by venture firms such as Fabric Ventures and Robot Ventures, Nansen has continued development since its 2020 domain registration. The product suits active decentralized finance traders and onchain analysts seeking trade execution alongside wallet intelligence.

Reviews highlight Nansen for on-chain research, wallet tracking, and trading insights, while criticizing expensive subscriptions and slow in-app updates that prevent normal background downloads.
“Worth the paid subscription If you’re even a semi-serious trader, paying the subscription for the Pro package is worth it. Over 10% of the tokens in my portfolio came through recommendations and insights from Nansen. I’m up on just about all of them.”
“Guys don’t miss out Even if you’re not an expert in cryptocurrency markets, if you want to follow successful people and easily monitor their moves, if you want to check token contracts and verify the team’s honesty in distribution without any manipulation or wallet linking tricks, and if you want…”
“Updating sucks Why is there updates within the apps and not through the AppStore.. to add insult to the injury it doesn’t even update in the background.”
“App price to use their AI way too expensive Phone beginners new to trading considering this app makes money on trading fees anyway to charge such extortionate amounts to use their AI app on the platform seems very unfair.”
