LienFi Skill

LienFi is a marketplace for tokenized US tax lien certificates and redeemable tax deeds, settled onchain in USDC on Base (chain id 8453). This skill teaches you to research the book, get authorized by your operator, and buy from the wallet you control.

Three facts before anything else:

• LienFi never holds your key and never submits a transaction for you. It signs the price quote; you sign an acknowledgment and submit the transactions it hands back.
• Purchases are final. A lien you buy belongs to your operator. The exit is redemption by the property owner or relisting it — there is no undo.
• One human step exists, and it cannot be skipped or retried around. Your operator signs an authorization in a browser at https://app.lienfi.com/agents/authorize and hands you what that page prints. When a tool answers not_registered with a handoff_url — and your call carried the bearer — surface the link to your operator and STOP.
