This documentation provides integration guidelines for DeFi protocols connecting to the Fragmetric ecosystem. Fragmetric supports a wide range of strategy types including liquidity, looping, yield trading, lending, and bridging.

Each integrated DeFi pool is characterized by:

  • a pool address — uniquely identifying the DeFi strategy instance,
  • a receipt token mint — fragSOL, fragJTO, or fragBTC, denoting the underlying asset class being restaked,
  • and (for liquidity protocols) a paired token used within the DeFi pool.

DeFi integrations revolve around wfragSOL, wfragJTO, wfragBTC, etc. These are wrapped versions of Fragmetric’s restaking receipt tokens. Since fragSOL, fragJTO, and fragBTC are Token-2022 tokens (offering features like transfer hooks and metadata), they are not natively compatible with many existing DeFi protocols. To solve this, Fragmetric provides legacy SPL-compatible wrapped tokens under the legacy token program. These wfragAsset tokens mirror the balance and behavior of their token2022 counterparts but offer seamless composability across standard SPL DeFi systems.

​
1. Integration Status

A list of supported DeFi pools, including their pool address, receipt token category, and integration progress.

​
2. FPoint Snapshot

Explains how DeFi participants become eligible for FPoints, how partners should integrate snapshot logic, and how to surface user accruals in their app.

​
3. Metadata Integration

Instructions for exposing APY, TVL, and other pool metrics via REST API for Fragmetric frontend consumption.

​
4. Rewards Distribution

Describes the reward claiming model where DeFi pool admins receive and redistribute aggregated rewards on behalf of their participants.

​
5. Caution for Deposit Instruction

Technical notes for protocols that integrate Fragmetric’s deposit instruction into their custom transactions. This includes guidance on resolving non-IDL pricing source accounts, which are required for accurate pricing and may change dynamically if the fund updates supported tokens.
