Overview

Bestlend aims to simplify the processing of lending and borrowing while maximizing your lending and borrowing rates. It will find the best rates from different lending apps on Solana and automatically move your funds for you. Bestlend will also swap between correlated assets so you can optimize your yield across all supported stables and LSTs.

For example, a user has USDC they want to earn a yield on. They deposit on Bestlend and the asset gets moved to the protocol with the highest yield. Bestlend may also decide to swap the USDC for USDT depending on the yield. The user then might decide to borrow against their collateral. When optimizing a user’s position, Bestlend will consider the lending rate of the collateral, the borrowing rate on the debt, and the staking yield of the assets.

Goals

• Simplify the process of lending and borrowing
  • aim to be the Jupiter of lending
  • not overwhelming the user with all the different lending protocols, pools, utilization rates, etc.
  • integrate with smart wallets like fuse and tiplink alongside eoa wallets
• Provide data to the user about their position
  • how have rates on their position changed over time
  • how has the value of their position changed over time
  • historical actions taken
• Make it easy for users to express a position
  • They want 2x exposure on an asset
  • They want to short an asset
  • boosted yield (find the biggest yield delta of SOL/LSTs and loop)

Non-Goals

The following are not the goals of the initial product. However, these are subject to change depending on user interest and how users interact with the platform. The plan is to be able to quickly pivot the product if necessary. For example, if users are primarily using the platform for lending and not borrowing then the product will focus on generating yield and work outside of lending protocols

Non-goals:

• Basis trades and other yield-generating positions outside of lending protocols
• portfolio management
  • the product is centered around a position that Bestlend is optimizing
  • no resting assets
• trading tooling
  • Bestlend will be able to swap user’s assets and run twaps but this isn’t a core feature and protocols like Jupiter are better for this
• distributing points
  • position on marginfi won’t earn points
• risk management
  • monitoring bad debt or depegs

How does Bestlend differ from Lulo

Bestlend will move your collateral around to get you the best rates like lulo.fi but will also swap your collateral if higher rates are available. For example, a USDC deposit on Kamino could be swapped and moved to USDT on Marinfi. Bestlend also allows you to borrow against your position and will move your debt around so you don't have to worry about rates changing or updating your position.

There should be no reason to use Lulo over Bestlend as the product should be just as simple yet offer more features
