# Introduction The proliferation of decentralized finance (DeFi), NFTs, and onchain enterprise applications has amplified the need for secure and efficient transaction execution mechanisms. Traditional blockchain interactions often involve complex interfaces, manual transaction preparations, and significant risks surrounding private key exposure. While wallet providers and hardware solutions offer incremental security improvements, they often compromise on user experience and accessibility. SignTx proposes a fundamentally new approach to onchain transaction management by integrating AI-driven transaction preparation with a secure, keyless signing environment. Leveraging advanced large language models (LLMs), SignTx interprets user instructions, prepares transaction payloads, and facilitates signing operations — all while keeping private keys isolated from both AI agents and network infrastructure. SignTx ensures maximum security and usability, empowering users to interact with blockchain networks through simple, secure, and intelligent workflows. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
