Congratulations on Nillion's main website in March~Let me introduce Nillion to you in a simple and easy way Recently, there have been several major security incidents in Web3 that have had a significant impact. Small scale security incidents occur almost every day, with new cases happening in studios or retail investors. Everyone is at risk for a while, and it seems that there is no pure land in the Web3 world that can be called absolutely safe. And if one day a major market trend arrives, security issues are often the first part that many people choose to sacrifice in the impossible triangle. Large amounts of funds bear security risks and rampage between chains, exchanges, and robots, just to gain a slightly leading entry opportunity. Nillion, a blind computing privacy and security network, has been committed to promoting the development of DeFAI's privacy solutions. Nillion is an underlying technology that enables all AI agents to securely process private data, maximizing the creativity of AI while ensuring the safe operation of the entire workflow Blind computing technology is not difficult to understand, which allows for secure processing of sensitive data without leaking its content. Nillion applies it to the DeFAI field, providing the correct tool combination for building both intuitive and secure DeFAI agents. With Nillion's SecretSigner, developers can create agents to sign transactions without disclosing sensitive private keys to the agents themselves. This ensures that users can trust these agents to securely execute transactions while fully protecting their assets. Its working principle is as follows: 1. Secure signature using the Nillion LangChain tool Nillion's LangChain tool utilizes SecretSigner to achieve secure transaction signatures. Users can store their ETH account private key as confidential in the Nillion network and grant computing privileges to specific AI agents for the private key. Agents will never see the private key in plain text form, but can safely use it to sign transactions. Users maintain full control and can revoke computing access at any time, immediately preventing agents from signing transactions on their behalf. 2. Transaction creation tool for DeFi workflow In order to simplify the decentralized financial workflow, AI agents are equipped with specialized tools for managing swaps and transaction creation. These tools seamlessly collaborate with Nillion's signature feature: Exchange Utility: A price checking tool used to find the best token exchange rate on platforms such as Uniswap, as well as other utilities to evaluate liquidity and optimize transaction execution Transaction Builder: Create approved transactions for exchanging and spending token amounts, ensuring accurate calculation and inclusion of all necessary parameters such as slippage, gas fees, and token amounts. These tools work together to provide agents with everything they need to securely create and sign transactions. The transaction creation tool handles the details of building effective exchanges, while Nillion's infrastructure ensures that private keys are always protected. This setting enables the DeFAI agent to securely execute transactions for users while ensuring the security of their private keys. Nillion has been one of the most anticipated mainnet launches in the past few months and will officially launch in March. Nillion received a $20 million financing led by Distributed Global at the end of 2022, and has been deeply involved in Web3 construction throughout the entire cycle. In October 2024, it completed a $25 million financing led by Hack VC, which can be considered as obtaining gold certification. The DeFAI track is relatively early, and many projects are still in the stage of castles in the air, but I have always been very interested in whether AI traders who abandon human emotions can understand the essence of trading. If the ultimate optimization of AI algorithms is the spiritual core that determines the upper limit of DeFAI, then a set of safe, reliable, and normally running infrastructure construction is the flesh and blood of DeFAI. I am looking forward to Nillion's mainnet launch to further advance the DeFAI track and bring more possibilities to the entire Web3.
