Aster
- Aster figures here assume you hold the $ASTER each fee tier requires (500 for VIP 2, up to 2.5M for VIP 6); without it you stay on VIP 1, 0.04%, at any volume.
- The amount per level is on the Aster page.
TxFlow
- TxFlow is an on-chain perp DEX: log in with email or a wallet and deposit USDC, no ID check.
- The Code takes 5% off your perp and spot fees, at the fill, on your first $25M of combined volume.
- Tiers use 14 day volume (perps plus spot together), scaled here to a monthly equivalent.
- A points program is live; points have often been followed by a token airdrop, but nothing is confirmed.
- New users may need an access code from TxFlow's Discord.

Questions
Which is cheaper, Aster or TxFlow?
One answer at every volume:
- At every volume: Aster is cheaper · $380 vs $428 at $1M
Why does the bigger rebate not always win?
A rebate is a share of the fee. A higher fee can hand back more dollars and still cost you more.
- Aster: 5% back on a 0.04% fee → you pay 0.0380%
- TxFlow: 5% back on a 0.045% fee → you pay 0.0427%
- What you pay is the fee after the rebate, not the rebate %
Can I use both codes?
Yes.
- They are separate exchanges, so each account gets its own rebate
- Open each one through its own Rakebk link or code
- A code only works on a new account
How are these numbers worked out?
- Every order counted as a taker
- At the fee tier your monthly volume reaches on each exchange's published ladder
- Minus the rebate
- Both ladders are on this page, read from each exchange's own fee page
