# Developer Referral Fee On Solend, 80% of fees are collected as a protocol fee with 20% earmarked as a host fee. The host fee goes to: (in order of priority) * Users with 1,000 SLND self-referring * Referrals from another address * Permissionless pool creators * Alternative UIs built on Solend smart contracts * Solend When calling the borrow function on the Solend smart contracts, a client may pass in an address to receive the 20% host fee. This is applicable to DeFi strategies integrating Solend (discount off fee), or alternative UIs to Solend's (pass in an address to receive some fees). This is an incentive to encourage developers to build on top of Solend. {% embed url="" %} --- # 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.
