The tiny coins that quietly control everything you do on-chain.
Back in Day 15–17, we talked about gas fees, those little costs you pay every time you send, swap, or stake crypto. We said gas is like the “service fee” for using a blockchain, paid to the network so your transaction can be processed.
But today, let’s zoom in on something people don’t always talk about clearly:
If gas is the fee…
👉 What exactly is a “gas token”?
And why do some people seem obsessed with collecting and hoarding them?
So, what is a gas token?
A gas token is simply the coin you use to pay gas on a specific blockchain.
- On Ethereum, the gas token is ETH.
- On Base, it’s also ETH, but on the Base network.
- On Polygon, it’s MATIC.
- On Solana, it’s SOL.
- On BNB Chain, it’s BNB.
You might hold USDC, USDT, or other tokens for value, but when it comes to moving those tokens, the network doesn’t accept them as payment.
It only accepts its gas token.
So even if you have ₱1 million worth of USDC, if you don’t have a little ETH (or SOL, or MATIC) for gas, you’re stuck.
You’re rich… but frozen.
The “stranded funds” moment
Almost everyone in crypto has experienced this:
You bridge funds from Ethereum to another chain, say Base.
You arrive, happy, with USDC ready to use.
Then… you try to swap.
Error.
You try again.
Error.
You finally realize:
You have USDC, but zero ETH on Base to pay gas.
Your money is there.
You can see it.
But you can’t move it.
That’s when you learn the hard way that gas tokens are like phone load, without even a few pesos of load, your phone is “online” but you can’t actually call or text.
Why people “hoard” gas tokens
Once you’ve been stranded without gas even once, you change your behavior.
You become that person who:
- Keeps a small stash of ETH on different networks.
- Holds a bit of MATIC if you use Polygon.
- Keeps some SOL aside if you’re active on Solana.
You’re not hoarding in the “degen” sense.
You’re hoarding in the prepared sense.
Gas tokens become your mobility money, the budget that lets you move, swap, stake, farm, or bridge when you want, not when it’s convenient to top up.
It’s like always keeping a little cash in your wallet even if you mostly use cards. Just in case.
Gas tokens vs “investment coins”
There’s a subtle mindset shift here:
Some coins you hold to invest, like BTC, ETH, SOL, or your favourite altcoin.
Some tokens you hold to use, like USDC or stablecoins.
Gas tokens sit in a special category: you hold them to do things.
You can invest in them, of course.
But their most important role is practical, not speculative.
They are the fuel of crypto.
Just like you don’t buy gasoline mainly to “invest in petrol,” you don’t hold gas tokens primarily for number-go-up. You hold them so your life in Web3 doesn’t get interrupted.
How much gas should you keep?
There’s no magic number, but here’s a simple mindset for beginners:
- On any network you regularly use, keep enough gas for at least 5–10 transactions.
- For Ethereum (where gas can be higher), that might mean a slightly bigger buffer if you know you’ll be swapping, bridging, or minting.
- On cheaper chains (Base, Polygon, Solana), even a small amount can last quite a while.
The goal isn’t to overthink it.
It’s just to avoid “stranded funds syndrome”, that feeling of being stuck because you forgot to bring gas money.
Bridging… just for gas
Sometimes, people even bridge a tiny bit of ETH or SOL to another network just to have gas there.
Example:
You might bridge $5 worth of ETH to Base not to trade, but simply so you have gas tokens ready whenever you need to do something on that chain.
It feels funny at first, moving money just so you can move money.
But that’s part of how these systems work today.
Until UX improves, keeping gas in different ecosystems is like keeping small wallets in different currencies when you travel.
Why gas tokens matter more than you think
It’s easy to ignore gas tokens when markets are exciting.
Everyone talks about meme coins, blue chips, NFTs, “next 100x.”
But at the end of the day, the tokens that quietly matter most are often:
- The ones keeping your transactions alive
- The ones your favorite networks depend on
- The ones you feel missing instantly when they’re not there
Gas tokens are the quiet backbone of your Web3 life.
Without them, everything else sits on pause.
Takeaway
Gas tokens are like the phone load, toll fee, and jeepney fare of crypto combined.
They’re not always glamorous, but they’re absolutely essential.
You don’t need a lot.
You just need enough, on the right chain, at the right time.
So the next time you top up your wallet, think not just about what you want to hold or trade… but also about what you’ll need to move.
