Nansen Wallet Manager

nansen-ai/nansen-cli

This handles wallet operations for the Nansen CLI: creating wallets (either encrypted locally or server-side via Privy), checking balances, sending tokens on EVM and Solana, and managing keys. The two-provider setup is the interesting bit. Local wallets encrypt keys on disk with a password stored in your OS keychain, while Privy wallets live server-side and need no password at all, which makes them cleaner for automated agent workflows. The skill enforces proper password handling: it will make Claude ask you for a password instead of generating one, and it knows not to use interactive flags. Supports dry runs, max balance sends, and the usual export and delete operations.

Authentication

Nansen account API calls accept a selected nansen:api browser session or conventional API key with the same permissions. NANSEN_API_KEY takes precedence; optional primaryEnv preserves configured-key injection. Run nansen auth status for offline selection. Cached access expiry alone permits automatic renewal during an authorized task. Stop on anonymous selection, invalid state, blocked/uncertain renewal or actual auth failure; never drop a credential or fall back to anonymous x402 payment. Browser login does not grant wallet signing, privileged service identity or a persistent MCP integration key. Preserve all confirmation, signing, sanctions and geographic checks below. Browser login is enabled in production within the documented platform scope.
