What is PILSO OS?

The LLM-native OS for secure onchain operations.

PILSO OS (Pilot Interface for LLMs Signature Operations) is a secure agent operating system that enables large language models (LLMs) to safely sign and execute onchain actions through Web3 wallets—starting with MetaMask, and expanding to all major wallet providers.

At its core, PILSO OS abstracts complex blockchain tasks—like token transfers, contract deployments, or network switching—into natural language prompts executed by modular agents. These agents are powered by LLMs (such as Claude, GPT...), and connected to a growing suite of MCP servers that handle each operational task in a trustless, pluggable way.

PILSO lets users and developers interface with Web3 infrastructure without writing code, exposing private keys, or building custom tooling—instead, they operate through secure, role-based AI agents capable of executing signed actions on-chain.

Why it matters

In today’s AI x crypto landscape, LLM-powered agents are rapidly becoming the next major interface layer for decentralized systems. However, most “AI agents” in Web3 suffer from a fatal flaw: they require access to the user’s private key or wallet control.

This breaks trust, introduces custodial risk, and fragments the user experience.

PILSO OS solves this by flipping the model:

• The wallet remains the signer.

• The LLM becomes the pilot.

• MCP servers act as the trusted middleware.

The result is a non-custodial, agent-executable, multi-provider interface—built for both technical builders and crypto-native users.

How it works

PILSO OS combines:

• Secure wallet signatures → All actions are signed locally by the user’s wallet

• Natural language interfaces → Prompt your agent like a co-pilot, not a coder.

• LLM runtime + role config → Choose specific agent behaviors and chain access scopes.

• MCP servers → Modular backends that execute tool-specific blockchain functions (e.g. sign, deploy, fetch, bridge, etc).

• CLI-first dev tooling → Power users can run sessions, customize behavior, and build on top.
