The integration between AI and Web3 has entered a concrete operational phase. The first wave was limited to the use of predictive models for chart analysis, while the second (now) has shifted to autonomous AI agents capable of interacting directly with smart contracts, managing liquidity, and executing complex transactions without constant human supervision.

What are On-Chain Agents and How Do They Work?

An on-chain AI agent is a software entity powered by LLMs equipped with their own cryptographic wallet. Unlike traditional algorithmic trading bots, which are anchored by rigid deterministic scripts, autonomous agents can:

- Interpret abstract goals: receive high-level parameters and autonomously plan on-chain steps

- Interact cross-chain: monitor liquidity pools and lending protocols across different Layer 2s, performing rebalancing via DeFi badges when network fees and yield spreads make it profitable

- Programmable self-custody: operate via granular permissions (session keys), avoiding exposing the master private key and limiting capital exposure to preset limits

Comparison: Traditional Bots vs. Autonomous AI Agents

Traditional bots: execute only fixed, hard-coded rules, require direct access to the private key, limited to APIs/hard-coded contracts, reactive risk monitoring (stop loss on price)

Autonomous AI Agents: adapt the strategy based on market conditions, use session keys and account abstraction, dynamic integration via contract readers and toolchains, risk monitoring Predictive and multidimensional (liquidity, audit, and gas fees).

Model Security and Reliability: Open Challenges

Despite the efficiency advantages, financial automation delegated to AI models introduces some risks:

- Incorrect model output can result in irreversible on-chain transactions and direct liquidity losses.

- Prompt vulnerabilities: If the agent reads unstructured data feeds (such as posts on X, various social media, and forums), or malicious actors can attempt logical exploits to divert funds.

- Overfitting on Historical Data: Strategies in stable market environments struggle to handle rare events like Black Swans or sudden liquidity crises in DeFi protocols.
