Gas Fees Explained

Crypto transactions use network (gas) fees to process and confirm activity on the blockchain.

This article explains what gas fees are, which actions require them, and who pays—without the fluff.

What are gas (network) fees?

TL;DR: Gas fees are paid to the blockchain network to process transactions — not to RockWallet.

Gas (also called network or mining fees):

  • Compensate the network for processing transactions

  • Keep blockchains secure and running

  • Vary based on network activity and demand

RockWallet does not set or profit from gas fees. They go directly to the blockchain network.

Which actions require gas fees?

Rule of thumb:
👉 Any action that writes to the blockchain requires a network (gas) fee.

Transaction types & gas fees

Action Uses the Blockchain? Requires Gas Fees? Who Pays the Fee?
Buy ✅ Yes ✅ Yes You
Sell ✅ Yes ✅ Yes You
Send ✅ Yes ✅ Yes You
Swap ✅ Yes ✅ Yes You
Receive ❌ No ❌ No Sender

What does not require gas fees?

  • Receiving crypto

    • The sender pays the network fee

    • You don’t need gas to receive funds

What asset pays the gas fee?

Gas fees are always paid in the native asset of the network being used.

Examples:

  • Bitcoin → fees paid in BTC

  • Ethereum / ERC-20 tokens → fees paid in ETH

  • Dogecoin → fees paid in DOGE

  • Litecoin → fees paid in LTC

  • XRP Ledger → fees paid in XRP

  • Bitcoin SV / MNEE → fees paid in BSV

💡 Important:
You do not need ETH unless you’re using the Ethereum network.

Why do gas fees change?

Gas fees can go up or down depending on:

  • Network congestion

  • How many transactions are waiting

  • The complexity of the transaction

Busy networks = higher fees
Quiet networks = lower fees

RockWallet shows you the estimated fee before you confirm, so you can review it first.

Can gas fees be refunded? No.

Once a transaction is submitted:

  • The network uses the fee to process it

  • Fees aren’t refundable — even if a transaction fails

This is a blockchain rule, not a RockWallet rule.

Common misunderstandings

  • ❌ I need ETH to send DOGE / BTC / LTC → False. Each network uses its own coin for fees.

  • ❌ Receiving crypto costs gas → False. The sender pays.

  • ❌ RockWallet charges gas fees → False. Fees go to the blockchain.

Quick recap

  • Gas fees are network fees, not RockWallet fees

  • Buy, Sell, Send, Swap → require gas

  • Receive → no gas required

  • Fees are paid in the network’s native asset

  • Fees vary based on network activity
