Understanding gas fees is key to using your Best Wallet. This guide explains why gas fees exist, how they work, and why you need the right cryptocurrency in your wallet to complete transactions.
What are gas fees and why do they exist?
Gas fees are small transaction fees paid to blockchain networks to process and validate transactions. These fees go to network validators (or miners) who ensure the blockchain remains secure and functional, and are never set or collected by Best Wallet.
Gas fees are required for:
Sending crypto to another wallet or exchange.
Buying a token in the Upcoming Tokens tab
Swapping tokens, even on decentralized exchanges (DEXs).
Claiming pre-launch tokens from Upcoming Tokens.
Interacting with decentralized applications (dApps).
The fee amount varies depending on the network you're using, how busy that network is, and the size of the transaction. When demand is high, gas fees can increase, especially on the Ethereum network.
Why do I need to hold the right crypto for gas fees?
Each blockchain has its own native cryptocurrency that is required for paying gas fees (these are often just called native tokens or gas tokens).
Currently, Best Wallet supports three major blockchains, meaning you may need the following:
Ether (ETH) → Needed for Ethereum transactions.
BNB (BNB) → Needed for BNB Smart Chain transactions.
Polygon (POL) → Needed for Polygon transactions.
If you don’t have the right crypto in your wallet, you won’t be able to send or swap tokens on that blockchain.
For example, if you have Tether (USDT) on Ethereum but no ETH, you’ll need to get ETH first before being able to send, spend, or swap your USDT
How to buy crypto for gas fees
The easiest way to get gas tokens is by buying them directly in Best Wallet:
Open Best Wallet and go to the Buy section.
Select the gas token you need (e.g., ETH for Ethereum transactions).
Choose a provider and complete your purchase.
Note: It’s always a good idea to first buy gas tokens, and to always hold some in your wallet, even if you don’t plan to make transactions immediately.
How to receive crypto for gas fees
If you already own gas tokens in another wallet or exchange, you can send them to your Best Wallet.
Copy your token or chain address for your wallet.
Send the gas token from your other wallet or exchange.
Wait a few minutes and check your wallet's balance.
Note: Always double-check that you’re sending the correct token on the right network. For example, if you want to deposit ETH on Ethereum, make sure you're sending it to your Ethereum address.
What can you do after covering gas fees?
Once you have gas tokens, you can:
Send and transfer crypto without transaction failures.
Buy Upcoming Tokens directly in your wallet.
Swap tokens across different networks.
Claim Upcoming Tokens when they launch.
Use dApps like DeFi platforms and NFT marketplaces.
Need help with gas fees?
If you’re having trouble with gas fees, check:
Do you have enough gas tokens? Transactions fail if you don’t have enough gas tokens to cover fees. It's always good practice to have a healthy buffer
Are you using the correct network? Make sure you’re sending or swapping on the right blockchain.
Are gas fees too high? If the network is congested, waiting for lower fees might help.
