Blockchains charge small fees to keep the network healthy. In Ethereum-style systems, those fees are called gas. Every action uses computing power, and gas pays for that work while discouraging spam.
World Mobile Chain follows the same model. Your wallet estimates how much gas an action will need and suggests a price. In most cases you can accept the default and continue. A simple token transfer usually costs less gas than interacting with a complex contract.
In short, gas is how World Mobile Chain measures and pays for the work the network performs. It keeps the system fair, fast, and resilient.
What pays gas on WMC?
Gas fees are paid in WMTx, the utility token that powers transactions, rewards, and services across the network.
Who needs WMTx?
That depends on how you use the chain.
- Builders and dapp users: keep a small WMTx balance for transaction fees.
- Token holders and stakers: you’ll need WMTx for staking and related actions.
- Mobile and broadband subscribers: most of the time you won’t handle WMTx directly. You pay in fiat, and the system converts what’s needed in the background.
Your wallet will estimate the gas for each action and suggest a fee. In most cases the default works and your transaction will confirm quickly.
How are gas fees calculated?
Every transaction on World Mobile Chain has two parts:
- Execution on WMC (L3 fee): the cost of running your transaction on the chain. This depends on how much computation and storage your action requires.
- Settlement to Base (L1 fee): the cost of posting batched proofs and calldata to Base. This fee can move up or down depending on how busy Base is.
The total fee is the sum of these two components. Your wallet automatically estimates both and suggests a single fee before you confirm.
Why are fees low on WMC?
WMC runs as a Layer 3 optimistic rollup that settles to Base, a Layer 2 on Ethereum. Instead of sending every transaction upstream, it bundles many actions together and posts a compact proof. That preserves Ethereum-level security while cutting overhead costs.
In testing, WMC has handled 500–700 transactions per second. Most of the heavy lifting happens off chain, with only the essentials anchored in batches. For users, that means everyday actions like logging in, calling a contract, recording usage, or receiving rewards stay quick and inexpensive.
Where do gas fees go?
Gas fees flow back into the network to keep it secure and sustainable.
- EarthNode operators: they verify users, process sessions, and anchor results on-chain. A portion of their earnings also flows to token holders who stake with them.
- Settlement: every batch of WMC transactions must be posted to Base. Gas covers the parent-chain storage and security cost.
- Spam prevention: by attaching a price to each action, gas keeps the system clear of junk transactions.
In short, gas fees cover WMC’s operations, settlement to Base, and rewards for the community.
Gas fees and network congestion
Like any blockchain, World Mobile Chain can see fees rise when demand is high. If many transactions compete at once, the price per unit of gas goes up so the network can process activity in an orderly way.
On WMC, the pressure is softened by its layered design. Most work happens on WMC itself, with only compact proofs posted to Base. That keeps heavy data off the settlement layer, so fee swings are usually smaller than on a congested Layer 1.
→ For most users this means steady, predictable fees for everyday actions. Your wallet will suggest a suitable fee, and the default usually works.
FAQ
Is gas on WMC measured in gwei?
No. Gwei is an ETH sub-unit. On WMC, fees are denominated in WMTx, and your wallet shows them as small WMTx amounts.
Why do fees sometimes vary?
The total depends on two things: how much work your transaction does, and current network demand. Because WMC batches activity as a rollup and settles to Base, swings are usually smaller than on a congested Layer 1.
Do EarthNodes mine blocks with my gas?
No. EarthNodes don’t produce blocks. They validate identity and usage, process session outcomes, and trigger on-chain actions. Gas and WMTx rewards compensate this work so the system runs smoothly.
