[tiago-hansen]

Additional Contract Information

• Is the rate provider reporting for a stable coin/FX/Yield tracking?
• Is the rate provider reporting a market rate?
• 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)

Protocol Documentation

The rate provider is a combined rate provider that multiplies two rates to denominate waMonsUSDe in USDe: (1) the waMonsUSDe ERC4626 rate in terms of underlying sUSDe (rate provider 0xC22b3a858208BEDF7E26103D4eF332F66dd08Aad), and (2) the sUSDe/USDe exchange rate (rate provider 0x82D50FfB2AEf03B288373E5C09761846FA580380, which reads the Chainlink SUSDE / USDE Exchange Rate feed at 0x34047f0e5261103f384F20b76A324b86d192f698). The combination is required because the underlying sUSDe is itself a yield bearing asset.
