Fees

On-chain spot trading on BBX follows a transparent maker-taker fee model. Trading fees are charged at the protocol level and vary based on the user’s VIP tier.

Fee Model Overview

BBX applies a maker-taker fee structure for on-chain spot trading:

• Maker fees apply when an order adds liquidity to the order book

• Taker fees apply when an order removes liquidity from the order book

Fee rates are determined by the user’s BBX VIP tier, which is calculated based on rolling 14-day trading volume across the BBX DEX.

Maker Fees

A maker order is an order that adds liquidity to the order book.

In on-chain spot trading, maker fees typically apply when:

• A limit order is placed at a price that does not immediately match an existing order

• The order remains in the order book until another trader executes against it

Maker orders contribute to market liquidity and may benefit from lower fees under higher VIP tiers.

Taker Fees

A taker order is an order that removes liquidity from the order book.

In on-chain spot trading, taker fees typically apply when:

• A market order is submitted

• A limit order is placed that immediately matches an existing order in the order book

Taker orders prioritize immediate execution and are charged according to the taker fee rate associated with the user’s VIP tier.

On-chain spot trading fees on BBX are determined by the BBX VIP System.

• Fee rates decrease as users qualify for higher VIP tiers
