Yearn USND ERC4626 and Rate Provider review

[zekraken-bot]

Additional Contract Information

• Is a combined rate provider needed (i.e. wstETH in aave)?
• Does this rate provider pertain to an ERC4626 contract?
• If so, is the intention for this ERC4626 asset to be boosted?
• If so, is the Buffer already initialized
• If so, shall the underlying asset be used to add/remove liquidity in a pool if possible? (i.e. add USDC for waUSDC)
• If so, shall the wrapped asset also be used to add/remove liquidity in a pool? (i.e. add waUSDC directly)
