Network Fees Explained
Understanding blockchain transaction fees and how they affect your exchanges

When exchanging cryptocurrencies, an important cost to consider is network fees. These fees are not charged by NinjaSwap, but are required by the blockchain networks to process your transactions. This guide explains what network fees are, how they're calculated, and how they affect your exchanges.

What are Network Fees?

Network fees (also known as blockchain fees, transaction fees, or gas fees) are payments made to blockchain network validators or miners who process and secure transactions on the blockchain. These fees serve several key purposes:

Economic Incentive

Fees compensate miners and validators for the computing resources they use to validate and process transactions. This incentivizes them to maintain the security and operations of the blockchain network.

Spam Prevention

By requiring a fee for each transaction, blockchain networks discourage spam and denial-of-service attacks that could otherwise overwhelm the network with worthless transactions.

Network fees are inherent to how blockchains work and are completely separate from any exchange fees charged by platforms like NinjaSwap. They're unavoidable when making any cryptocurrency transaction, whether you're sending crypto to another wallet or using an exchange service.

Important to Understand

Network fees are paid directly to the blockchain network, not to NinjaSwap or any other exchange service. These fees vary by network, transaction size, and network congestion, and they're required regardless of which exchange service you use.

How Network Fees Work on Different Blockchains

Each blockchain network has its own mechanism for calculating and applying network fees. Here's how fees work on some popular networks:

BlockchainFee MechanismTypical Fee RangeFee Variability
Bitcoin (BTC)Satoshis per byte (transaction size-based)$0.50 - $5.00Medium - High
Ethereum (ETH)Gas price × Gas limit (computational complexity)$1.00 - $20.00+Very High
Tether (USDT) on TronFixed bandwidth system with very low fees$0.01 - $0.10Very Low
Solana (SOL)Fixed flat fee per transaction$0.00025 - $0.001Very Low
Binance Smart Chain (BSC)Gas price × Gas limit (like Ethereum but cheaper)$0.10 - $0.30Low
Ripple (XRP)Fixed fee with slight variations$0.0002 - $0.001Very Low
Cardano (ADA)Two-component fee (fixed + per-byte)$0.15 - $0.30Low

Fee Variability

The fee ranges above are approximations and can vary significantly based on network congestion, transaction complexity, and market conditions. Always check current fee estimates before making transactions.

What Affects Network Fees?

Several factors influence the network fees for cryptocurrency transactions:

1

Network Congestion

This is the most significant factor for many networks. When more people are trying to make transactions, fees increase as users compete to have their transactions processed faster. During peak trading periods or market volatility, fees can spike dramatically, especially on networks like Ethereum.

2

Transaction Complexity

More complex transactions (like token swaps on Ethereum or smart contract interactions) require more computational resources to process and validate, resulting in higher fees. Simple transfers typically have lower fees than complex contract interactions.

3

Transaction Size

For some blockchains like Bitcoin, the physical size of the transaction data (measured in bytes) affects the fee. Transactions involving multiple inputs or outputs are larger and therefore more expensive to process.

4

Transaction Speed Priority

Many wallets and services allow you to select how quickly you want your transaction to be processed. Choosing a faster processing time will result in higher fees. For less urgent transactions, you can often save money by selecting a slower processing speed.

5

Blockchain Network Design

Different blockchains have fundamentally different designs that affect fee structures. Newer blockchains like Solana and Avalanche were specifically designed for lower fees and higher throughput compared to older networks like Bitcoin and Ethereum.

High-Fee Networks

  • Ethereum (ETH) - Especially during high congestion
  • Bitcoin (BTC) - During periods of high transaction volume
  • ERC-20 tokens - Any token operating on the Ethereum network

These networks can see fee spikes of 5-10x normal amounts during peak congestion.

Low-Fee Networks

  • Solana (SOL) - Known for consistently low fees
  • Ripple (XRP) - Very low fixed transaction costs
  • Tron (TRX) - Popular for USDT transfers due to low fees
  • Binance Smart Chain (BSC) - Cheaper alternative to Ethereum

These networks maintain relatively stable, low fees even during high activity.

Network Fees in the Exchange Process

During a cryptocurrency exchange on NinjaSwap, network fees come into play at two critical points:

Deposit Transaction Fee

When you send cryptocurrency to the exchange address provided by NinjaSwap, you pay the network fee for this transaction from your wallet. This fee goes to the miners/validators of the sending cryptocurrency's blockchain.

Example: If you're exchanging Bitcoin for Ethereum, you'll pay a Bitcoin network fee when sending your BTC to the exchange address.

Settlement Transaction Fee

After the exchange is processed, NinjaSwap sends the exchanged cryptocurrency to your destination address. The network fee for this transaction is deducted from the amount you receive.

Example: Continuing with the BTC to ETH exchange, a network fee for the Ethereum blockchain will be deducted when sending the exchanged ETH to your wallet.

Understanding the Total Cost

When calculating the total cost of your exchange, remember to consider both network fees (for sending and receiving) as well as any exchange fee charged by NinjaSwap. The total amount you receive will be:

Amount Received = (Amount Sent × Exchange Rate) - (Exchange Fee + Settlement Network Fee)

How Network Fees Affect Minimum Exchange Amounts

Network fees are a key factor in determining the minimum exchange amounts on NinjaSwap. For cryptocurrencies with high network fees (like Ethereum during congested periods), the minimum exchange amount needs to be high enough that the fees don't consume a disproportionate percentage of the transaction value.

Example Scenario

Consider an exchange from Ethereum (ETH) to Bitcoin (BTC) during a period of high Ethereum network congestion:

  • Current ETH network fee: $15.00
  • Exchange amount: $50.00 worth of ETH
  • Percentage lost to network fee: 30%
  • Current ETH network fee: $15.00
  • Exchange amount: $300.00 worth of ETH
  • Percentage lost to network fee: 5%

As you can see, exchanging small amounts during high fee periods can result in a significant percentage of your funds being consumed by network fees. This is why minimum exchange amounts fluctuate with network conditions.

Tips for Managing Network Fees

While network fees are unavoidable, there are strategies to minimize their impact on your exchanges:

Time Your Transactions

For networks with variable fees like Ethereum and Bitcoin, transaction costs tend to be lower during periods of reduced activity. Weekends and non-peak hours often have lower network congestion and fees.

Check fee tracking websites like etherscan.io/gastracker for Ethereum or mempool.space for Bitcoin to monitor current fee levels.

Consider Alternative Networks

For tokens available on multiple networks, consider using the network with lower fees. For example, USDT is available on Ethereum (high fees), Tron (low fees), and Binance Smart Chain (moderate fees).

Higher fees:USDT (ERC-20)USDT (TRC-20)Lower fees

Batch Transactions

Instead of making multiple small exchanges, consider combining them into one larger exchange when possible. This reduces the number of network transactions required and can save on total fees paid.

Use Exchanges with Fee Coverage or Rebates

Some exchange services (including certain promotions on NinjaSwap) may offer to cover or partially rebate network fees, especially for larger transactions. Keep an eye out for these promotions if you're planning a large exchange.

Frequently Asked Questions

Why do network fees sometimes cost more than the exchange fee?

Network fees are determined by blockchain congestion and transaction complexity, not by the value being transferred. During high congestion periods, network fees can exceed exchange fees, especially for smaller transactions. This is similar to how shipping a small, inexpensive item might cost more than the item itself.

Can NinjaSwap reduce network fees?

NinjaSwap (and other exchange services) cannot directly reduce blockchain network fees as these are determined by the blockchain protocols themselves. However, NinjaSwap does optimize transactions where possible and occasionally runs promotions where we cover part or all of certain network fees for eligible exchanges.

Why do I sometimes see different network fees for the same cryptocurrency?

Network fees can vary based on:

  • Time of day and current network congestion
  • Type of transaction (simple transfer vs. contract interaction)
  • Transaction priority setting in your wallet
  • Which network the token is on (e.g., USDT can be on Ethereum, Tron, or other networks)

If I cancel an exchange, do I get network fees back?

If you cancel an exchange before sending funds, you won't incur any network fees. However, if you've already sent funds and then the exchange is canceled or refunded, the network fees for the initial transaction cannot be refunded as they've already been paid to the blockchain network. Additionally, the refund transaction will incur its own network fee, which is typically deducted from the refunded amount.

Summary

Understanding network fees is essential for making informed cryptocurrency exchanges:

  • Unavoidable Cost: Network fees are required by blockchain networks to process transactions, separate from exchange fees
  • Variable Factors: Fees vary by blockchain, congestion levels, transaction complexity, and timing
  • Two Fee Points: In an exchange, you typically pay network fees twice—once when sending to the exchange and once when receiving your exchanged cryptocurrency
  • Minimum Impacts: High network fees directly affect minimum exchange amounts, especially on networks like Ethereum
  • Optimization Possible: You can reduce fee impacts by timing transactions, considering alternative networks, and batching exchanges
