Trustless Execution

Private keys never exposed to LLMs

MetaMask Integration

Seamless wallet connection and signing

Modular MCP Stack

Powered by scalable MCP servers

Key features

Built for AI Agents. Designed for Secure, Wallet-Based Signing.

Trustless Onchain Execution

No shared keys. No delegated wallets. Transactions are signed directly via your Web3 wallet — never by the AI.

Private Key Abstraction

PILSO abstracts sensitive signing logic away from agents — keeping keys securely in MetaMask, or any supported wallet.

Scalable MCP Modules

PILSO runs on isolated servers (MCPs) for signing, compiling, and more — you control which tools your AI agent can access.

Human-in-the-Loop Controls

Final approval always stays with you — review and sign actions triggered by agents before they reach the chain.

How It Works

A simple, secure four-step process that bridges AI intelligence with blockchain execution

Natural Language Input

PILSO translates agent prompts into structured transaction flows — no need for custom code.

MCP Server Processing

PILSO routes the request to the correct MCP module for simulation.

Wallet Signature Request

A MetaMask or Web3 wallet prompt appears. You review and sign — the agent never sees your private key.

Secure Onchain Execution

The signed transaction is broadcast to the blockchain — safely and transparently, without custody risk.

Core MCP Modules

The infrastructure powering PILSO OS. Each server specializes in a core onchain operation — securely delegated to the user’s wallet.

metamask-mcp

Automate governance processes with AI agents that can understand complex proposals and execute approved actions seamlessly.

Architecture Overview:

Agent → chainlist-mcp → Fetches RPC, chain ID, symbol → Passed to tx modules

chainlist-mcp

Enable AI-driven smart contract interactions for complex DeFi strategies, yield farming, and protocol management.

Architecture Overview:

Agent → erc20-mcp → chainlist-mcp → metamask-mcp → token transfer or approval

erc20-mcp

Securely signs transactions via MetaMask without exposing private keys.

Architecture Overview:

Agent → metamask-mcp → MetaMask UI → User signs → tx is sent

solc-mcp

Deploy AI customer service agents that can help users with onchain operations, refunds, and technical assistance.

Architecture Overview:

Agent → solc-mcp → solc-js → Compiled Output → signer

Powering PILSO OS

From agent prompts to transaction signatures, PILSO OS combines modular tools into a secure system for executing AI-driven onchain operations.

Role-Based Agent Design

LLMs follow predefined rules and tasks, making every agent safely predictable.

img

Modular MCP Servers

PILSO’s tooling is modular — each MCP server adds a specific capability.

img

Secure Wallet Signatures

Agents don’t sign — the user’s wallet always signs onchain transactions.

Multi-Provider Interop

Works with Claude, GPT-4, and other LLMs — with support for metamask and all major wallets.
