The Popular DeFAI Cryptocurrency Nillion is Set to Launch! Nillion Demonstrates How to Prevent AI Agents from Compromising Security
Decentralized finance (DeFi) has long held two primary aspirations: to enhance user experience and to strengthen security. These two aspects are crucial for attracting the next billion users into the Web3 world. However, for many potential users, complex interfaces, rigid terminology, and cumbersome operational processes have posed significant barriers. Today, DeFAI (AI-driven DeFi applications) and Nillion are joining forces to change this reality, leveraging artificial intelligence (AI) and innovative security technologies to deliver a new solution that offers users a simple, intuitive, and secure DeFi experience.
The startup project Nillion teased the launch of its mainnet in February 2025 at the end of December last year. Recently, it showcased the security capabilities brought by AI agents through a popular AI proxy application; this has heightened the anticipation among participants of the Nillion airdrop regarding its developments this year. Nillion may currently be one of the hottest AI tokens.

What is DeFAI? Redefining the DeFi Interaction Experience with AI
Imagine your DeFi experience being as simple as chatting with ChatGPT. This is the vision DeFAI aims to achieve: to replace cumbersome operations with a natural language interface, allowing users to complete financial transactions through conversation. From asset management to trade execution, DeFAI’s AI agents can automatically handle operational details, making DeFi more intelligent and accessible.
Security is Paramount: Nillion’s Secret Weapon SecretSigner
While user experience is important, another core challenge of DeFi lies in security. Here, Nillion’s SecretSigner tool plays a critical role. It provides a secure foundation for DeFAI’s intelligent agents, enabling users to trust the agents to execute transactions without worrying about private key leakage or asset theft.
Collaboration Between DeFAI and Nillion to Strengthen Security: Essential Infrastructure for AI Agents
How do DeFAI’s intelligent agents achieve both intuitiveness and security? This is made possible by the support of Nillion’s Signature technology. Below are the key tools and their operational mechanisms:
1. Secure Signing Functionality of Nillion LangChain Tools
Nillion’s SecretSigner technology allows users to store their ETH account’s private key as “secret” data and grants AI agents the computational authority over the private key. Notably, the agent never directly “sees” or handles the plaintext private key; it can only perform signing operations in a secure environment. Users always retain control and can revoke the agent’s computational authority at any time, ensuring security.
2. Tools for Creating DeFi Transaction Workflows
To simplify DeFi operations, AI agents are equipped with specialized trading tools that cover the entire workflow from token swapping to transaction creation:
– Swapping Tool: The agent can perform price queries, find the best token exchange rates on platforms like Uniswap, and assess liquidity to optimize transaction execution.
– Transaction Building Tool: The agent can generate swap transactions or token approval transactions, automatically calculating parameters such as slippage, gas fees, and token amounts to ensure accurate transaction execution.
Through Nillion’s infrastructure and tools, DeFAI intelligent agents can handle all transaction details while ensuring the security of private keys.
Practical Applications of Nillion Technology: Preventing AI Agents from Compromising Security
On January 18, Nillion released a demonstration video showcasing this technology, allowing viewers to see how users can request AI agents to “buy tokens,” with Nillion ensuring security:
– Storing Private Keys: Users store their ETH private keys with Nillion and grant AI agents computational authority.
– Simulated Transaction: Users instruct the agent to purchase $1 worth of ETH. The subsequent operations are entirely handled by the agent:
– Data Verification: The agent queries prices and liquidity to ensure the transaction is feasible.
– Token Authorization: The agent generates an authorization transaction, permitting the router to use the user’s USDC, and signs the transaction securely with Nillion.
– Executing Swap: The agent creates a swap transaction, sets all parameters (e.g., slippage and gas fees), and uses Nillion to sign and complete the transaction.
– Receiving Tokens: After the transaction is completed, users receive the swapped WETH and can view on-chain results through the transaction hash.
The Future of DeFi: Intuitive, Intelligent, and Secure
This demonstration proves that the combination of DeFAI agents and Nillion’s signing technology makes decentralized finance simpler and safer. From querying data to signing transactions, AI intelligent agents automatically handle tedious steps, allowing users to participate in DeFi without needing to delve into technical details. This intelligent and secure approach will be a key driving force behind the widespread adoption of DeFi.
Risk Warning
Investing in cryptocurrencies carries a high level of risk, and their prices can be highly volatile; you may lose your entire principal. Please assess the risks carefully.
