The rise of decentralized exchanges (DEXs) has revolutionized how users exchange cryptocurrencies. In contrast to centralized exchanges, DEXs provide better security, transparency, and asset control. However, one of the largest fears for traders is fees on transactions. With 2025 introducing new innovations, let's discuss which decentralized crypto exchange has the lowest fees and why it is important.

• Trading Fees – Percentage fee per trade, generally lower than for centralized exchanges.
  
  

• Withdrawal Fees – Fees to transfer assets from the platform.
