1. Network fee (“gas”)
Gas is the fee paid to the Arbitrum network to process your transaction: a swap, adding liquidity, staking, anything. It’s always paid in ETH, regardless of which tokens you’re dealing with.- It goes to the network, not to PrigeeX.
- It’s small on Arbitrum, usually a few cents, because Arbitrum is a low-cost Layer 2 network.
- You need ETH to cover it. Even if you’re only trading USDC, you must keep a little ETH in your wallet for gas, or transactions will fail.
2. Trading fee
The trading fee is a small percentage charged on each swap. This is the fee that:- Rewards liquidity providers for supplying the pool you traded against, and
- Funds the platform, a portion of which is paid out to PGX stakers.
Where PrigeeX’s revenue goes
A share of trading fees becomes platform revenue. That revenue is split 70% to PGX stakers and 30% to the PrigeeX treasury, converted into PGX. This is why staking ties your earnings directly to how much the platform is used. See PGX Tokenomics.Why a swap might fail (and what to do)
A failed transaction still costs a little gas, so it’s worth avoiding. Common causes:Slippage in plain terms: the price can shift slightly between clicking and settling.
Your slippage tolerance (default 0.5%) is the most you’ll accept before the trade
cancels itself to protect you. Volatile tokens may need a slightly higher tolerance to go
through.
Keeping costs down
- Keep a small ETH buffer on Arbitrum so you never get stuck.
- Batch your actions when you can: each transaction costs gas.
- Don’t over-collect tiny fees on Concentrated positions; collecting also costs gas, so let them build up a bit first.
