Navigating the world of DeFi swaps: evolution and the future



Decentralized Finance (DeFi) revolutionizes the way we exchange assets, allowing for cryptocurrency swaps through smart contracts on blockchain networks. This innovation bypasses the need for a middleman, ushering in a new era of financial autonomy and flexibility.

Advantages and disadvantages of performing swaps on DEXes

DeFi swaps, among other venues, can be facilitated by decentralized exchanges (DEXes), which employ automated market makers (AMMs) and liquidity pools to ensure trades reflect real-time supply and demand. 

AMMs are at the core of DEXes, facilitating a decentralized trading model. AMMs distinguish themselves from traditional exchanges by using a mathematical formula instead of order books to set asset prices in a liquidity pool, bypassing the need to directly match buyers and sellers. This formula can vary across different DEXes but typically involves the product of the quantities of the two tokens remaining constant. Liquidity providers fund these pools by depositing pairs of tokens, and in return, they receive a portion of the trading fees plus potential liquidity mining rewards. This model allows for seamless, automated trading without the need for traditional market makers.

Advantages of DEX swaps

  • Full control of assets. The absence of a centralized authority holding users’ funds eliminates the risk of unauthorized access, ensuring that users’ assets remain secure. This direct control empowers users to manage their investments without intermediaries, offering unparalleled security and peace of mind.
  • Enhanced privacy.  Users can engage in trading without surrendering personal information, safeguarding them from potential data leaks. This ensures that traders’ personal details and assets are beyond the reach of any organization, preventing misuse of sensitive information.
  • Elevated security measures. The architecture of DEXes, where user funds are not stored on the exchange itself, significantly reduces the risk of hacks. Security on DEXes is fortified by smart contracts, which are frequently audited and optimized to ensure the integrity of transactions. 

 Disadvantages of DEX swaps

  • Low liquidity and impact on order execution. Smaller or newer DEXes may suffer from low trading volumes, affecting the execution of large orders without price impact.
  • The gas fee challenge. Fluctuating and sometimes high gas fees on networks like Ethereum can detract from the cost-effectiveness of swaps. Also, the need  to always hold native tokens for paying gas fees might be challenging for both newcomers and seasoned traders.

DEX aggregation and how it works

DEX aggregators enhance the efficiency and effectiveness of swaps by aggregating liquidity from multiple DEXes to find the best exchange rates for users. This process involves scanning various liquidity pools across different platforms to execute a swap at the most favorable rate, thereby minimizing slippage and maximizing trade value. A DEX aggregator can be integrated directly into crypto wallets, providing users with a consolidated entry point to the vast DeFi market. This not only simplifies the swap process but also significantly improves liquidity, facilitating easier execution of larger trades without substantial market impact.

The future of DeFi swaps

1inch’ s Fusion represents a significant advancement in DeFi swaps by aggregating liquidity from the entire market, from DEXes to CEXes. This approach broadens the asset pool available for swapping on 1inch and introduces unparalleled efficiency and convenience for users.

  • Gas-free and MEV-protected swaps. By eliminating network fees, swaps become more affordable. And MEV protection ensures swaps will not be attacked by bots executing front-running or sandwich attacks. 
  • Lowering barriers. The removal of network fees could significantly reduce the entry barrier for DeFi participation, making it more attractive to a wider audience.



The evolution of DeFi swaps is steering financial transactions toward a more democratic, efficient and interconnected future. With new solutions, the transformative potential of DeFi in global finance is not just on the horizon—it’s happening now.
