DeFi traders in 2025 rely on advanced DeFi tools for analytics, automation, and MEV protection in decentralized finance.
Lower transaction fees and AI-powered platforms are making DeFi faster, smarter, and more efficient for DeFi traders.
Tools like DeFiLlama, Nansen, 1inch, CoW Swap, and DeFi Saver create a complete ecosystem for research, trading, and risk management in DeFi.
Decentralized Finance (DeFi) has grown fast thanks to cheaper transaction fees and better trading tools. After Ethereum’s Dencun upgrade in 2024, fees on Layer-2 networks became much lower. This encouraged more people to trade on-chain. DeFi’s total value locked (TVL) has also increased again, reaching around $150 to $170 billion across different blockchains. In this fast-moving market, certain tools help traders make better decisions, manage risk, and improve profits. Let’s take a look at the most useful DeFi tools for traders.

DeFiLlama is a popular website that shows how much money is locked in different DeFi platforms. It tracks TVL, trading volumes, and how money moves between blockchains and protocols. It shows total DeFi TVL in the mid-100 billion dollar range. This tool helps traders understand where their finances are going and which platforms are gaining or losing users.
Dune allows anyone to create and use custom dashboards based on blockchain data. It is built by the community, and new dashboards appear quickly when a new token or protocol becomes popular. Dune updated its system to handle higher traffic and improved its credit model for users. It is useful for checking real on-chain data, like token trades, pool volumes, and stablecoin supply, in a visual and easy way.
Nansen specializes in tracking wallet activity on many blockchains. It uses labels like “smart money,” “funds,” or “exchanges” to show who is buying or selling. The platform also launched Nansen AI, an assistant that uses blockchain data and market signals to help traders spot trends faster. This AI tool provides insights based on real-time wallet movements. It also became more affordable by adding new pricing tiers.
Arkham focuses on revealing which organizations or people control certain blockchain wallets. The platform sends alerts when large wallets move funds or interact with an exchange. Arkham AI Insights was introduced recently. It connects wallet movements with news and market events. This helps traders understand who is behind big trades and what it might mean for the market.
When sending transactions on Ethereum, there is a risk of losing money to MEV (Maximal Extractable Value), such as front-running or sandwich attacks. Flashbots Protect helps in stopping this by sending transactions privately.
MEV-Share is another tool that allows part of the MEV to be shared with the trader instead of being taken by others. These systems have become more mature and are widely used as they help traders get better profits and avoid losses.
1inch is a decentralized exchange (DEX) aggregator. It searches many platforms to find the best swap price for a trade. In June 2025, 1inch updated its Pathfinder algorithm. This upgrade improved trading rates by up to 6.5 percent and reduced gas fees. This helps traders save money, especially when making large or frequent trades.
CoW Swap uses a unique method for trading. Instead of sending direct exchanges to DEXs, it uses 'solvers' that compete to find the best result. Trades are grouped in batch auctions, which reduces MEV risk.
CoW Swap provides cross-chain exchanges by blending trading and bridging in a single step. It also expanded to the BNB Chain and started offering gasless trades. This makes it a strong option for safe and efficient transactions.
DeFi Saver helps automate finance strategies. It is popular for managing loans in platforms like Maker, Aave, and Compound. The platform has features such as automatic debt repayment, stop-loss, and take-profit tools.
DeFi Saver gave support for EIP-7702 in August 2025, which allows normal wallets to perform advanced smart contract actions in one trade. It also made automation easier and faster on Layer-2 networks.
MetaMask is one of the most popular crypto wallets. Its Portfolio feature makes it more powerful. This tool allows users to track all tokens, NFTs, and DeFi positions across different networks in one place. It also offers staking services and built-in bridges.
In early 2025, new updates were added to make self-custody safer and improve the platform. This tool helps traders quickly move funds and access DeFi exchanges without leaving their wallet.
Zapper is a dashboard that shows all DeFi assets, NFTs, and wallet activity in real time. It supports multiple blockchains and wallets. The mobile apps were improved for better speed and accuracy.
Zapper also helps traders discover new protocols by showing what active wallets are doing on-chain. This makes it helpful for monitoring overall portfolio health and exploring new opportunities.
Two major changes are affecting how DeFi tools are used in modern times. First, transaction fees on Layer-2 networks are much lower after Ethereum’s upgrades. This makes activities like frequent trading, automated strategies, and arbitrage cheaper and more profitable. Second, AI is becoming a key part of DeFi tools. Platforms like Nansen and Arkham now use AI assistants to deliver insights faster and more clearly.
