# Trade Mining Parameters

> DerivaDEX trade-mining rules: reward budget, maker and taker splits, volume-weighted payout formulas, 8-hour distributions, and DDX crediting behavior.

DerivaDEX trade mining distributes DDX, the platform's governance and utility token, to active traders in proportion to their trading volume over the trade-mining window.

## Trade-mining parameters

A fixed DDX budget is distributed each trade-mining epoch, then split between maker-side and taker-side volume.

| Parameter                        |             Value | Notes                                              |
| -------------------------------- | ----------------: | -------------------------------------------------- |
| Reward asset                     |             `DDX` | Credited to the trader's DDX balance               |
| Public distribution cadence      |   Every `8` hours | Rewards are distributed at the settlement boundary |
| Baseline reward budget per epoch | `3196.347031` DDX | Derived from `35,000,000 / (3 × 10 × 365)`         |
| Maker reward share               |             `20%` | Applied only to maker-side volume                  |
| Taker reward share               |             `80%` | Applied only to taker-side volume                  |

## Payout formulas

Maker and taker volume are rewarded in separate buckets.

```text theme={null}
maker_reward(trader) =
  maker_share × epoch_reward × trader_maker_volume / total_maker_volume

taker_reward(trader) =
  taker_share × epoch_reward × trader_taker_volume / total_taker_volume

trader_total_reward = maker_reward(trader) + taker_reward(trader)
```

| Volume profile in the window     | Reward result                                |
| -------------------------------- | -------------------------------------------- |
| Positive maker volume only       | Trader participates only in the maker bucket |
| Positive taker volume only       | Trader participates only in the taker bucket |
| Positive maker and taker volume  | Trader can receive both components           |
| Zero maker and zero taker volume | Trader receives no trade-mining reward       |

## Worked payout cases

These examples use the public baseline epoch budget of `3196.347031` DDX, with a `20%` maker bucket and an `80%` taker bucket.

| Trader volume in the window | Market totals in the window          | Reward                                               |
| --------------------------- | ------------------------------------ | ---------------------------------------------------- |
| `50` maker, `0` taker       | `200` total maker, `0` total taker   | `159.81735155` DDX (`0.2 × 3196.347031 × 50 / 200`)  |
| `0` maker, `120` taker      | `0` total maker, `600` total taker   | `511.41552496` DDX (`0.8 × 3196.347031 × 120 / 600`) |
| `50` maker, `120` taker     | `200` total maker, `600` total taker | `671.23287651` DDX (`159.81735155 + 511.41552496`)   |

## Eligibility and accounting

Trade mining is trader-level accounting, not strategy-level collateral accounting.

| Rule               | Effect                                                                              |
| ------------------ | ----------------------------------------------------------------------------------- |
| Reward destination | Rewards credit the trader's DDX balance                                             |
| Event emitted      | A reward emits `TRADER_UPDATE` with reason `TradeMiningReward`                      |
| Accrual basis      | Volume is accumulated over the trade-mining window, then cleared after distribution |
| Ordering           | Recipients are paid once per eligible distribution window                           |

## When rewards are not distributed

The maker and taker buckets are independent.

| Case                                   | Outcome                                             |
| -------------------------------------- | --------------------------------------------------- |
| No maker volume in the window          | The maker bucket does not distribute                |
| No taker volume in the window          | The taker bucket does not distribute                |
| No maker or taker volume in the window | No trade-mining distribution occurs for that window |

Unused volume on one side does not roll into the other side's bucket automatically.

These values are governance-controlled and can change through DAO proposals.
