Decentralized Finance (DeFi) has long sought two major goals: enhancing user experience and strengthening security. These two elements are crucial for attracting a billion users into the Web3 world. However, over the years, complex interfaces, stiff terminology, and cumbersome operational processes have deterred many potential users. Now, DeFAI (AI-driven DeFi applications) is collaborating with Nillion to change the status quo by leveraging artificial intelligence (AI) and innovative security technologies to deliver a new solution that provides users with a simple, intuitive, and secure DeFi experience.
The startup Nillion teased its mainnet launch in February 2025 at the end of December last year and has recently showcased the security capabilities brought by AI agents through its popular AI applications. This has heightened the anticipation among secret verification participants awaiting the Nillion airdrop, as Nillion could be one of the hottest AI tokens currently available.
(Nillion successfully completed the Verifier program, with the community collectively completing 195 million secret verifications)
What is DeFAI? Redefining DeFi Interaction Experience with AI
Imagine your DeFi experience being as simple as chatting with ChatGPT. This is the vision DeFAI aims to achieve: replacing cumbersome operations with a natural language interface, allowing users to complete financial transactions through conversation. From asset management to trade execution, DeFAI’s AI intelligent agent (AI Agent) can automatically handle operational details, making DeFi smarter and more 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 intelligent agents, enabling users to trust agents to execute transactions without worrying about private key leakage or asset theft.
DeFAI and Nillion Collaborate to Reinforce Security: Essential Infrastructure for AI Agents
How do DeFAI’s intelligent agents achieve both intuitiveness and security? This is made possible through the support of Nillion’s Signature technology. Here are the key tools and how they operate:
1. Secure Signing Functionality of Nillion LangChain Tools
Nillion’s SecretSigner technology allows users to store the private keys of their ETH accounts as “secret” data and grants AI intelligent agents computational permissions for the private keys. Notably, agents never directly “see” or handle plaintext private keys; they can only perform signing operations within a secure environment. Users always maintain control and can revoke the agent’s computational permissions at any time to ensure security.
2. Tools for Creating DeFi Transaction Workflows
To simplify DeFi operations, AI intelligent agents are equipped with dedicated trading tools covering the entire process from token swapping to trade creation:
– Token Swapping Tool: Agents can perform price inquiries, find the best token exchange rates on platforms like Uniswap, and assess liquidity to optimize trade execution.
– Trade Construction Tool: Agents can generate swap trades or token approval transactions, automatically calculating parameters such as slippage, gas fees, and token amounts to ensure correct trade execution.
Through Nillion’s infrastructure and tools, DeFAI’s intelligent agents can handle all transaction details while ensuring private key security.
Practical Application of Nillion Technology: Preventing AI Agents from Compromising Security
Nillion released a demonstration video of this technology on January 18, showcasing how users can request the AI agent to “buy tokens,” with security guaranteed by Nillion:
– Storing Private Keys: Users store their ETH private keys with Nillion and grant the AI agent computational permissions.
– Simulating Transactions: Users instruct the agent to purchase $1 worth of ETH. The subsequent operations are entirely handled by the agent:
– Checking Data: The agent queries prices and liquidity to ensure the transaction is feasible.
– Authorizing Tokens: The agent generates an approval transaction, allowing the router to use the user’s USDC, and uses Nillion to securely sign the transaction.
– Executing Swap: The agent creates a swap transaction, setting all parameters (e.g., slippage and gas fees), and completes the transaction using Nillion’s signature.
– Receiving Tokens: After the transaction is completed, the user receives the swapped WETH and can view the on-chain results through the transaction hash.
The Future of DeFi: Intuitive, Smart, 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 cumbersome steps, allowing users to participate in DeFi without needing to understand the technical details. This intelligent and secure approach will be a key driving force for the widespread adoption of DeFi.
Risk Warning
Cryptocurrency investments carry a high level of risk, and their prices can fluctuate dramatically, potentially leading to the loss of your entire principal. Please assess risks carefully.
