Feature

What needs to be shipped?

• Update the documentation to include a clear explanation of keeper rewards and how they function.

• Add a section to the yLockers FAQ explaining that veYFI rewards are distributed in epochs and may not appear to accrue in real-time.

• Enhance the User Guide's withdrawal section with a step-by-step guide on how to handle LP tokens received from factory vaults, including a link to the relevant DEX.

• Review vault pages on the Yearn website to ensure all active vaults have a clear and concise strategy description.

• Update the FAQ to address the lack of a native P&L dashboard and suggest third-party tools like Zapper or DeBank for portfolio tracking.

• Update the User Guide with a troubleshooting section for withdrawals, covering zero balance issues (due to staking) and using Etherscan as a backup.

• Create a dedicated FAQ entry explaining manual harvesting for low-TVL vaults, including steps to call the harvest function via the keeper contract.
  Enhance the FAQ with common wallet errors, explaining client-side issues (status 400), cache clearing, and how to change RPC URLs.

• Update the developer documentation to clarify that Yearn is not a DEX and does not offer swap/quote API endpoints, directing users to the correct GraphQL endpoint.

• Add a section to the User Guide about using yVault tokens as collateral on partner platforms like Morpho, with a clear disclaimer on liquidation risks.
