Trade Mining Parameters - DerivaDEX Docs

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.

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.
