# 2. F Point Snapshot

> DeFi Integration for wfragAsset

**F Point** is a unified point system used to measure user contributions across DeFi integrations and Fragmetric platform. It is used to determine future eligibility for the `FRAG` token airdrop.
To support this, Fragmetric takes periodic snapshots of `wfragAsset` balances held within integrated DeFi protocols. Each DeFi partner is responsible for implementing a snapshot module that emits per-user balance data in a standardized format.

## Integration Requirements

You must implement a `SourceStreamFactory` that produces `{ owner, baseTokenBalance }` entries for all users in your protocol's pool.

* Create your snapshot source module under:
  [https://github.com/fragmetric-labs/fragmetric-snapshot/tree/main/src/commands/snapshot/source](https://github.com/fragmetric-labs/fragmetric-snapshot/tree/main/src/commands/snapshot/source)
* Implement the snapshot logic:
  * Validate arguments.
  * Call `produceSnapshot(...)` for each user.
  * Call `close(...)` at the end or on error.
* Register your source in `sources.ts`.
* Implement a smoke test file for the actual pool with your source.
* Submit a pull request.

## Snapshot Rules

1. TVL Must Match
   The total of all baseTokenBalance values must exactly equal the pool’s actual `wfragAsset` TVL. This guarantees snapshot integrity and fair accounting.

2. Liquidity Category Exception
   For protocols in the **LIQUIDITY** category, You may convert the full LP token value into synthetic `wfragAsset` terms (e.g., `fragSOL + JitoSOL → wfragSOL`).
   This is allowed to compensate liquidity providers for impermanent loss and to incentivize liquidity depth in DeFi integrations.

## To Display User F Point Accrual from Your Pool

To show users their current F Point accruals from your DeFi pool, utilize the following public API:

[https://api.fragmetric.xyz/v1/#/operations/GetUserFPointEstimationsByDeFiPool](https://api.fragmetric.xyz/v1/#/operations/GetUserFPointEstimationsByDeFiPool)

You can pass the user's wallet address and your pool address as parameters. The response provides real-time accrual data, which can be rendered in your frontend to reflect live F Point estimates.
Use this API to integrate user-facing F Point display into your app or dashboard.
