Gas and network fees
You don’t need ETH to use KURV. Sign in, hold USDC, and press the button. The network fee comes out of your USDC, in the same step as your action. For what this looks like on testnet today, see What’s live right now.
What a network fee is
Section titled “What a network fee is”Every action written to Base (a launch, a mint, a sale) costs a small network fee, also called gas. That fee pays for the network. KURV does not get it.
Network fees are separate from KURV’s fees. They are never part of any fee percentage. See Fees for what KURV charges.
One network, one dollar coin
Section titled “One network, one dollar coin”KURV runs on Base only. Prices are in native USDC, issued by Circle on Base. Bridged copies are never used. On testnet, that means Circle’s own test USDC on Base Sepolia. More in Chains.
What happens when you press a button
Section titled “What happens when you press a button”- You press the button (for example, Launch).
- You confirm once in your KURV wallet.
- Everything that step needs goes out as one operation from your same address. That includes any USDC approval, so there is no separate “approve first” step. The approval and the action happen together, or not at all.
- Coinbase’s paymaster pays the network in ETH for you, and takes the equivalent network fee from your USDC.
Your address doesn’t change. Your balances and collections stay where they are.
Who pays the network fee
Section titled “Who pays the network fee”You do, the person pressing the button. It comes out of your USDC, taken by Coinbase’s paymaster after your action runs. KURV never gets any of it; the fee goes to the network and to Coinbase for running the paymaster.
On Base, network fees are usually cents. They change with network conditions, so these docs don’t quote an exact figure.
Have a little extra USDC
Section titled “Have a little extra USDC”Your wallet needs enough USDC for the action plus its network fee. KURV checks this before it sends anything. If you’re short, it tells you how much USDC to add, and nothing is sent.
When a transaction fails
Section titled “When a transaction fails”If a transaction reverts, no KURV fee survives the revert. Network costs sit outside KURV’s fee schedule, so a failed transaction can still cost a network fee.
