Fees
Every fee you pay on Interstate, in one place. No hidden charges.
Trading fees
Interstate charges a platform fee of 1% of the trade's SOL value on every Solana spot trade, applied at execution — you'll see it reflected in the trade preview before you confirm.
A portion of that fee is paid back to you as SOL cashback based on your Airdrop Genesis rank (10% → 35%). See the Airdrop Genesis overview for the full cashback table.
Withdrawal fees
| Chain | Fee | Notes |
|---|---|---|
| Solana | 0.0005 SOL | Flat fee per withdrawal, network costs included |
| Monad | Network gas | See below |
Fees are charged from the withdrawing wallet's balance. If the balance can't cover the fee plus the requested amount, the withdrawal is rejected at pre-check.
You can fetch the current withdrawal fee from the app before initiating a withdrawal.
Priority fees (Solana)
Priority fees are a SOL tip to validators to get your transaction included faster during congestion. They are not Interstate revenue — the SOL goes directly to the validator.
- User-configurable per trade or in Quick-Buy presets
automode sets the tip dynamically based on network conditions, capped by yourmaxFeesetting- Higher tip = better inclusion odds during heavy traffic
MEV tips (bribes)
Optional additional SOL tip routed through Jito bundle submission or Nozomi to protect against front-running. Also not Interstate revenue — the tip goes to the block builder.
MEV protection via Jito / Nozomi currently works for imported local wallets only. Turnkey-backed wallets fall back to standard RPC submission.
Onramp fees
Fiat-to-crypto onramps are provided by Onramper. Fees depend on the selected partner, payment method, and region.
- Coinbase integration: up to $500 / week with no KYC
- Other partners (card, bank transfer, Apple Pay, etc.) each publish their own fee schedule inside the Onramper flow before you confirm
Onramp fees are shown in the Onramper widget before purchase.
Monad (Beta)
Monad trading is in beta and uses a different gas model.
| Item | Rule |
|---|---|
| Gas charged on | gasLimit, not gas used |
| Estimate buffer | +10% applied to every estimate |
| Max gas per tx | 30 million |
| Wallet reserve | 10 MON must remain at all times |
| Finality | ~800 ms (Finalized); receipt ~400 ms |
The 10 MON reserve is enforced at pre-check — trades that would drop the wallet below this are rejected.
Airdrop Genesis cashback
Every Solana spot trade earns SOL cashback on the platform fee:
| Rank | Cashback |
|---|---|
| Degen | 10% |
| Warrior | 15% |
| Gladiator | 20% |
| Commander | 25% |
| Titan | 35% |
Cashback accumulates in your balance and can be claimed to your wallet once it's at least 0.005 SOL, with a 5-minute cooldown between claims. Claims are real on-chain SOL transfers, not a virtual balance.
See Airdrop Genesis overview for how ranks work and how to climb them.
