Skip to main contentYield Source Adapters function as standardized interfaces within the FRAG-22 protocol, enabling secure interaction between the internal asset management system and external yield-generating protocols. Each adapter implements clearly defined operations such as asset allocation, yield harvesting, and asset withdrawal, ensuring transparent, consistent, and secure management of deployed assets.
Core Functions of Yield Source Adapters
Each Yield Source Adapter must implement the following standardized functions according to the FRAG-22 protocol specifications:
- Asset Allocation
-
Function:
allocate(amount: u64)
Moves specified assets from the FRAG-22 Reserve Account to the external yield source.
- Yield Harvesting
-
Function:
harvest() → yield_amount: u64
Retrieves generated yields from external yield sources and deposits them into the FRAG-22 Reward Reserve Account.
- Asset Withdrawal
-
Function:
withdraw(amount: u64)
Withdraws assets from the external yield sources back to the FRAG-22 Reserve Account.
- Status Reporting
-
Function:
report_status() → {allocated_assets: u64, accumulated_yield: u64}
Reports the current state of allocated assets and total accumulated yield, ensuring internal transparency and accurate record-keeping.
Adapter Structure and Operation Flow
Existing Implementations (by Fragmetric)
Fragmetric currently maintains two fully operational Yield Source Adapters integrated within FRAG-22:
- Liquid Staking Adapter
- Restaking Adapter
These existing adapters demonstrate robust and secure integrations that follow the standardized Yield Source Adapter interface.
Custom Yield Source Adapter Development
The modular architecture of FRAG-22 allows external developers to create and propose new adapters that conform to the predefined adapter interface. Operators will review and validate each adapter’s implementation before approving any asset allocation.
Adapter Activation and Asset Allocation Management
Operators hold exclusive permissions to manage the activation status and asset allocation parameters for each Yield Source Adapter. This ensures controlled asset exposure, risk management, and compliance with the FRAG-22 asset management strategy.
Allocation Management Flow:
The FRAG-22 Yield Source Adapter framework provides a standardized, transparent, and secure approach to extending and integrating various external yield-generation strategies, empowering a scalable and adaptable asset management ecosystem.
