The ugliest number first: sign up for Backpack through this site and the rebate is 10% — far below the 80% our other five venues pay. If the rebate rate is all you care about, stop reading and take the rankings page to one of the five. Still here? Then you are probably interested in Backpack itself — which is the right order to decide in.
Backpack fees: the sticker price vs what you actually pay
| Order type | Listed fee | After the 10% rebate |
|---|---|---|
| Spot — maker / taker | 0.090% | 0.081% |
| USDⓈ-M futures — maker | 0.020% | 0.018% |
| USDⓈ-M futures — taker | 0.050% | 0.045% |
Who Backpack is actually for
Backpack is a Solana-native exchange. Its spot sticker of 0.09% ties OKX for the lowest of the six, and its futures schedule (0.020% / 0.050%) sits in the cheap camp. Where it earns its place is the Solana ecosystem: listings arrive earlier and books run deeper for SOL-side assets. The 10% nets spot to 0.081% — modest, but credited in real time under exactly the same rules as the other five venues: computed on fees you actually paid, no thresholds.
The sensible setup: keep your main size on the 80% venues, use Backpack when the asset lives on Solana — and have the rebate bound on both, so every fill that can pay you back does.
On 400,000 USDT of monthly taker-futures volume (fee 0.050%): you pay 200 USDT in fees and 20 USDT comes back. Over a year, that is 240 USDT.
Referral code vs referral link
They do the same job — bind your new account to a partner — but the link does it without typos and without a form field. What matters is what neither can do: an existing account cannot be re-bound. Codes are accepted at sign-up only, and once an account is created, no setting anywhere adds or changes its referral. That rule belongs to Backpack, not to any particular partner.
So the practical route to the rebate is a fresh account on an email or phone number Backpack has never seen. The whole process is the three steps below.
How to check it actually applied
Place one small order after signing up. A partner-routed rebate is credited to your Backpack account in real time after the fill, so a single trade tells you immediately whether the account is earning it. No rebate line after a fill means the account is bound elsewhere — or not bound at all.
Backpack binds referrals through the link only — there is no code to type.
Three steps, start to finish
- Open Backpack through the link below. The link binds the new account to the rebate program automatically — no code to type.
- Complete KYC and deposit. Standard Backpack onboarding. There is nothing to do on the RAILSDESK side.
- Trade as usual. Same pairs, same leverage, same strategy. After every fill the rebate lands in your exchange account, permanently.
Open Backpack and earn the 10% back on every fill
Sign-up takes about two minutes; after that every fill earns its rebate automatically. Want to compare all six venues first? The rankings page has them side by side.
