Panoramic view of the AI ​​Agent track analyzed by 10,000 words: market value of 100 billion, 70 projects

Author: Alvis, MarsBit

I believe everyone is familiar with the concept of AI. From Turing machines to deep learning, from chess Deep Blue to Go AlphaGo, from The Matrix's Agent Smith to NVIDIA's Eureka, AI Agents are quietly changing our world. Now, with the blessing of blockchain, AI Agent is moving from theory to practice, gradually leaving the laboratory and entering our daily lives.

You read that right! These agents are not just "humanoid robots" in science fiction movies, they are more likely to become "virtual residents" in the blockchain ecosystem, managing assets, executing contracts, and even making decisions on their own, having an "independent" economy like you and me. Behavior. Today, let’s talk about this emerging wave in Crypto—the AI ​​Agent track.

According to CoinGecko data, the current total market value of the AI ​​Agent track reaches US$13.3 billion, approaching 100 billion yuan. There are an endless stream of AI Agent projects on the market, with a mixture of good and bad. After researching more than 150 AI Agent projects, the author carefully selected 70 representative projects. The total market value of these projects has exceeded 11 billion US dollars, covering six major tracks. This article will use these 70 projects to provide you with a detailed analysis of the AI ​​Agent track and reveal the opportunities and challenges.

Track Overview: Who is AI Agent?

First, we have to figure out what exactly an AI Agent is. You can understand that AI Agent is a "virtual agent" that has the ability to learn on its own and can perform tasks autonomously. It is not just an assistant or tool, it is more like an independent individual that can run freely in a decentralized blockchain network. It does not require constant instructions from humans, but makes decisions independently and completes preset tasks through continuous learning and optimization.

This kind of AI Agent is different from the common voice assistants we have today (like Siri, Xiaoai classmates). Those assistants only provide services by recognizing your commands, while the AI ​​Agent exists independently. It can learn independently, adapt to the environment, make decisions, and even manage assets and trade on the blockchain. Imagine that your digital wallet is no longer a rigid digital ledger. It will automatically make buying and selling decisions based on market changes, and even optimize your investment portfolio for you.

Why is everyone rushing to grab this field now? The reason is simple - AI Agent not only has huge technical potential, but also has huge market demand. The decentralized nature of the blockchain enables AI Agents to interact and trade directly with other agents or systems without an intermediary. This method of disintermediation is particularly suitable for application scenarios that require independent decision-making, such as investment management, automated trading, smart contract execution, etc.

So, to put it bluntly, AI Agent is a "smart program" that can think independently like a human and can even complete some complex tasks without any human intervention. Being able to run autonomously on the blockchain, execute smart contracts, and even participate in governance and economic decision-making is no ordinary artificial intelligence. It may lead a revolution in the integration of blockchain and artificial intelligence.

AI Agent Track: The future is already here

According to Messari predictions, it is expected that by the end of 2025, 90% of on-chain transactions will no longer be clicked "send" by real humans, but will be executed by a group of AI agents. These agents can not only perform micro-payments based on real-time data feedback, but also continuously optimize the liquidity pool, reasonably distribute rewards, and achieve more efficient and intelligent operations.

It may sound easy to imagine, but in fact, the accumulation of various technologies in the blockchain field (L1, rollup, DeFi, NFT) in the past seven years has quietly paved the way for a world where AI Agents run on the chain. Ironically, many builders don’t even realize that they are building infrastructure for a machine-dominated future.

Why did this shift occur?

• Eliminate human errors: The core feature of smart contracts is that they are executed exactly according to the predetermined code and cannot be interfered with. In turn, AI agents can process large amounts of complex data faster and more accurately than real humans, reducing human error and operational errors.
• Micropayments and high-frequency transactions: The operation of AI agents will make on-chain transactions smaller, more frequent, and more efficient. Especially on L1/L2 platforms such as Solana and Base, transaction costs are showing a downward trend, which further promotes the expansion of the AI-driven trading ecosystem.
• Invisible infrastructure: With the gradual development of decentralization and automation, more and more users are willing to give up direct control and instead let AI agents perform the tedious management work on their behalf.

The combination of these factors has promoted the widespread application of AI Agent and prompted it to become a core component of the L1/L2 platform, further promoting the innovation of the blockchain ecosystem.

Six branches of the AI ​​Agent track

The breadth and diversity of the AI ​​Agent track are not only reflected in its ability to cross the boundaries of various industries, but also in the richness of its subdivisions. In order to help everyone understand this rapidly developing field more clearly, the author conducted in-depth research on more than 150 AI Agent projects on the market and selected 70 representative projects. These projects span the six major tracks of AI Agent infrastructure, AI Agent LaunchPad, AI MEME, DEFAI, TEE verifiable agents, and AI applications, and their total market value exceeds US$11 billion, demonstrating the unique potential of AI Agent in different scenarios.

Conclusion: The future and challenges of AI Agent

The development of AI Agent is moving towards a more autonomous and intelligent direction. With the continuous advancement of technologies such as blockchain, decentralized finance, and TEE, the independence and autonomy of intelligent agents will be enhanced as never before. In the future, AI Agents will not only be tools or assistants, but may also become “economic agents” with independent economic behavior and decision-making capabilities.

However, despite the promising prospects, the evolution of AI Agents still faces many challenges. From the deep integration of technology, data privacy protection, to the improvement of regulatory policies and market education, every aspect puts forward higher requirements for the development of AI Agents. We are standing on the threshold of a new era. How to balance the "wisdom" and "autonomy" of AI Agents still requires the industry's joint efforts.

The AI ​​Agent of the future will completely break the traditional business model, create a new economic form, and even redefine the relationship between humans and machines to some extent. We have witnessed the beginning of this process, and we can only expect it to bring us more surprises and changes.
