Backpack fees & measured trading cost
Exchange fee pages quote one number; the order book charges three. FeeFloor measures Backpack's spot market on BTC, ETH and SOL — fee plus the spread and slippage the fee page never mentions, so a $100K BTC spot market order currently costs $115.89 all-in. The full measured breakdown is below, ranked against every venue we track. We count only what a market order pays to execute — funding, withdrawals and gas are measured separately.

What our measurements show
At $100K, Backpack runs 26% above the median venue we track (11.59 bps vs 9.17 bps).
The cost here is fee-dominated: 10.00 bps of the 11.59 bps total at $100K is the venue's own fee, over a book tight enough that spread and slippage barely register.
Spot execution at $100K runs 11.59 bps all-in (#15 of 21 spot venues) — more expensive than the same trade on its futures book right now.

How FeeFloor measures Backpack
FeeFloor measures Backpack on its spot market for BTC, ETH and SOL, pricing from the live order book.
The fee component is Backpack’s published standard-tier (VIP0) taker rate; spread and slippage are walked live from its order book at four trade sizes. FeeFloor measures execution cost only — funding, withdrawals, fiat conversion and borrowing are not included.
Regulatory assessment is outside FeeFloor’s scope: we measure execution cost, not whether Backpackis legally available to a given user. Legal-entity and regulatory data are not independently verified by us — see Sources & verification below.
