Fees
Devnet trading fees are 0%. No maker, taker, or liquidation fees are charged during the devnet phase.
The mainnet fee schedule will be published before launch.
How fees are calculated
notional = price * size / 10^8
fee = notional * fee_bps / 10,000Rounding favors the protocol: positive fees (taker pays) are rounded up, negative fees (maker rebates) are truncated toward zero.
Liquidation fees
There is no liquidation fee in the post-vault model. The Liquidator Vault inherits inventory from underwater accounts at the user's entry price; the vault realizes PnL on the unwind in lieu of a fixed fee. See liquidations.
Where fees go
Trading fees accumulate in the Parcl Treasury. While fees are 0%, the Treasury grows only from net funding flow on imbalanced open interest and from PnL the Liquidator Vault realizes on unwound inventory.
