Key Features at a Glance

LLM-agnostic, wallet-agnostic, chain-agnostic, modular.

PILSO OS delivers secure, modular infrastructure to let LLM agents safely execute onchain actions using any Web3 wallet.

Here’s what sets it apart:

---

Wallet-as-Signer Security

• Private keys never leave the wallet

• All transactions are signed client-side via MetaMask (WalletConnect and others coming soon)

• Removes need for custodial agents, bots, or key delegation

---

LLM-Compatible Execution Layer

• Compatible with Claude, GPT-4, DeepSeek and other LLMs

• Agents interpret natural language instructions and convert them into secure blockchain operations

• Role-based agent personalities ensure scoped behavior (e.g. “signer”, “developer”, “auditor”)

---

Natural Language Interface

• Abstracts away RPCs, ABI formats, and tooling jargon

• Prompts like “Deploy this contract on Sepolia Testnet or bridge 50 USDC to Optimism” are interpreted, executed, and signed securely

• Enables true agent UX across wallets and chains

---

Modular MCP Server Framework

• Each blockchain task runs on a dedicated MCP server

• Server modules are composable and trustless

• Examples include:

  • metamask-mcp – transaction signing

  • chainlist-mcp – chain info fetch

  • solc-mcp – smart contract compile

  • erc20-mcp – token actions

---

CLI Runtime for Power Users

• Run local agent sessions via terminal

• Configure models, roles, environments

• Resume, replay, and audit sessions

• Used by devs building custom automations or prototypes

---

Non-Custodial by Design

• No token approvals needed

• No middleman wallets

• No signature hijacking

• You sign what you see. Agents execute what you allow.

---

Extensible for Builders

• Add custom MCP servers to integrate with dApps, data sources, or off-chain APIs

• Define agent roles with personality, task scope, and execution behavior

• Build on top — don’t reinvent the stack
