# Marketplace (in development) Users on friendo.cash can take their NFT-based referral trees and engage in various financial activities within a dedicated secondary marketplace created by friendo.cash. On this marketplace, users can: * **Buy**: Purchase existing referral tree NFTs to start earning passive income immediately from the connected network that built the previous owner. * **Sell**: Sell their referral tree NFTs to other users, transferring the associated referral tree (income stream) to the buyer. * **Collateral**: Leverage their referral tree NFTs as collateral for loans or other financial transactions, using the future income potential of their network as security. This marketplace adds liquidity and flexibility to the friendo.cash ecosystem, allowing users to maximize the value of their referral trees. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
