Crypto gas fees explained

A gas fee is the small payment you make to a blockchain network to process your transaction — like postage for sending value. It goes to the validators who secure the network, not to any company.

What is "gas"?

Every action on a blockchain — sending tokens, swapping, deploying a contract — uses computing power. Gas is the unit that measures that work, and the gas fee is what you pay for it, in the chain's native coin (BNB, ETH, SOL).

Why do gas fees go up and down?

Most chains use a simple auction: when many people transact at once, fees rise; when the network is quiet, they fall. Fees depend on network demand and how complex your transaction is (deploying a token costs more than a simple transfer).

Gas fees by chain

• Solana — a fraction of a cent; the cheapest.
• BNB Chain — typically well under $1.
• Base & Arbitrum — a few cents (layer-2s).
• Ethereum — the most expensive, from a couple of dollars to much more when busy.

Why layer-2s are so cheap

Base and Arbitrum are "layer-2" networks that bundle many transactions together and settle them on Ethereum. You get Ethereum-grade security at a tiny fraction of the cost — ideal for creating a token affordably.

How to save on gas

• Choose a low-fee chain (Solana, BNB Chain, Base, Arbitrum) for your launch.
• Transact when the network is less busy.
• Keep a small amount of the native coin in your wallet to cover fees.

What you pay to create a token

Creating a token costs the network gas fee plus a small flat service fee — and nothing else. There are no subscriptions. Exact amounts per chain are shown on each token creator page before you deploy.

How are gas fees calculated?

A gas fee is not a single fixed number — it is the product of two things: the amount of computational work your transaction needs (measured in gas units) and the price you pay per unit (the gas price, set by network demand). A simple token transfer uses little gas; a complex contract interaction uses more. On many networks the gas price has a base fee that rises and falls with congestion, plus an optional priority fee (a tip) to get included faster. Multiply the work by the price and you get the fee — which is why the same action can cost cents one moment and more the next as demand shifts.

This also explains why deploying a token costs more than a simple transfer: creating a token runs a contract, which takes more gas than just moving coins. But on a low-fee chain even a contract deployment stays cheap, because the gas price is so low to begin with.

Gas fees and how a chain is secured

Gas fees are also tied to how a blockchain secures itself. On Proof-of-Stake networks — which most modern low-fee chains use — validators are paid partly through these fees, and the efficient design keeps costs low. The fee you pay is what compensates the network for processing and securing your transaction, with no bank or processor taking a cut. Understanding this makes gas feel less like an arbitrary charge and more like what it is: the cost of using a decentralised, secure network that no single company runs.

Gas in a multichain world

Because every chain has its own fees, your choice of network is the biggest factor in what you pay — and in a multichain world you have many options. The same token you want to launch can cost very different amounts to deploy depending on the chain. That is why, if low cost matters, picking a low-fee network is the single most effective decision. When you create a token, you pay only the network gas fee for that chain, and you can choose from 22 of them.
