+# Rate Provider: StakedYUSD rate provider
+
+## Details
+This report was autogenerated on 18/02/2026.
+
+- Deployed at:
+    - [Ethereum:0x785D401051E1e0df29aBc99043Fe5c542252E1a3](https://etherscan.io/address/0x785D401051E1e0df29aBc99043Fe5c542252E1a3)
+- Audit report(s):
+    - [Audits](https://docs.aegis.im/audits)
+
+## Context
+The rate provider tracks the embedded yield of the sYUSD token
+
+## Review Checklist: Bare Minimum Compatibility
+Each of the items below represents an absolute requirement for the Rate Provider. If any of these is unchecked, the Rate Provider is unfit to use.
+
+- [x] Implements the [`IRateProvider`](https://github.com/balancer/balancer-v2-monorepo/blob/bc3b3fee6e13e01d2efe610ed8118fdb74dfc1f2/pkg/interfaces/contracts/pool-utils/IRateProvider.sol) interface.
+- [x] `getRate` returns an 18-decimal fixed point number (i.e., 1 == 1e18) regardless of underlying token decimals.
+
+### Administrative Privileges
+- [ ] The Rate Provider is upgradeable** (e.g., via a proxy architecture).
+- [x] Other contracts which are part of the `getRate` callchain are upgradeable**. You can find more information
+   about the involved contracts in this [tenderly simulation](https://www.tdly.co/shared/simulation/de21b16b-f265-4b95-8d68-180979ebc45b)
+
+## Conclusion
+**Summary judgment: USABLE**
+
+** upgradeable in this context means that:
+- The contract is a proxy contract with an implementation sourced from Etherscan and the proxy emitted an "Upgraded" event.
