Key updates made between September 12 and September 26.

Polygon validators and user balances: Introduced a new rewards persistence layer to enhance yield balance calculations when fetching user balances that do not originate from the Yield API.
Yo Protocol: Refactored yield integration to replace the old yoGateway + custom ERC-4626 implementation with new proxy contracts that are fully ERC-4626 compliant.
Bittensor updates:
- Improved Bittensor transaction handling: Integrated Taostats API to fetch extrinsic IDs by hash, introduced network-specific search parameters for optimized lookups, and updated RPC provider configuration.
- Added support for Bittensor root validators to be displayed alongside other subnet validators
Yearn APY update: Switched from retrieving 30-day APY to a 7-day APY

OAV indexing:
- Price per share tracking: introduced a new feature to support snapshots of price per share for yield integrations
- APY calculations: Instead of relying on third party APIs for retrieving APY information on the underlying yields, we started performing calculations based on the PPS increases
Added skipPrecheck as a transversal argument for transaction construction: Added support for a new skipPrechecks argument across the Yield API and core modules. Updated DTOs, OpenAPI/Swagger docs, and core interfaces to expose the option, and propagated it through transaction construction paths in ChainsYieldModuleAdapter. This allows clients to bypass pre-execution checks when needed.
rateType fix: Improved yield rate type determination by factoring in the rewardClaiming property instead of relying only on yield type. Now returns APY for auto-claiming and APR for manual claiming, ensuring more accurate rate representation across staking and restaking yields.
Yield Shield Service: Introduced the new Shield library to validate unsigned transactions against predefined patterns, ensuring safety before signing. Added Solana transaction decoding and instruction sequence checks, along with comprehensive tests using real transaction data.
