VenusLens

Introduction

The read only functions on the VenusLens contract provide a view into: - metadata of vToken - daily XVS rewards for an account - account balance for a single vToken - account balances for all vTokens in an account - underlying price of a vToken - underlying prices for a set of vTokens - get liquidity and shortfall of an account - get user's vote history - get proposal details for a set of proposals - get account XVS balance, total votes, and delegated votes - get historical voting balance for a user - get pending XVS Rewards for an account
