Company profile
researched Aug 2026Nansen (Nansen AI) is a blockchain analytics and trading platform that enriches onchain data with wallet labels and delivers it through web, mobile, API, MCP and CLI interfaces. Its core dataset covers more than 500 million labeled blockchain addresses across networks including Ethereum, Solana, Base and BNB Chain, with coverage described as spanning 18+ to 25+ chains depending on the product surface. Signature features include "Smart Money" tracking of funds, market makers, whales, public figures and top-performing traders; PnL leaderboards; real-time wallet alerts; token screening (Token God Mode); wallet profiling (Profiler); and multichain portfolio tracking [0][2][3][5].
The platform has extended from analytics into execution. Nansen AI supports spot trading on Solana and Base with order routing aggregated across Jupiter, OKX DEX and LI.FI, and perpetual futures on crypto and real-world assets such as stocks and indices via Hyperliquid. Trades can be placed manually in a terminal or through an "agentic" AI assistant that answers natural-language onchain questions (due diligence, price explainers, transaction decoding) and can execute in the same conversation. Wallets are non-custodial with multi-factor authentication, powered by Privy. A points program rewards trading activity with tier-based fee reductions and partner perks, and referrals can earn USDC rewards [0][2][3].
Nansen also sells programmatic access to the same endpoints that power its dashboards, via a REST API, an Anthropic Model Context Protocol server for tools like Claude and Cursor, and an open-source command-line interface. Access is credit-based (about $0.001 per API credit, with 100 free credits to test) or through x402 pay-per-call micropayments in USDC on Base or Solana, priced from $0.01 per call for a basic tier and $0.05 per call for a premium tier that includes agent credits, unlimited portfolios and full access to PnL and Smart Money labels. The company additionally operates as a Hyperliquid validator with over $1B HYPE staked [3][5].
