Introducing Sigil

We're excited to introduce Sigil — an open-source platform for building, managing, and running autonomous AI agents on the Solana blockchain — entirely from your local machine.

The Problem

Today's wallets are passive. They sit idle until you click a button. If you want to monitor token prices, rebalance a portfolio, or execute conditional trades, you need to be glued to your screen.

Sigil changes that. Instead of reacting to the market, your agents act on your behalf, continuously running a reasoning loop that leverages real-time on-chain data.

How It Works

At its core, Sigil runs a LangGraph-powered agent loop. Each cycle:

Fetches your balances, token holdings, and market data from Solana Devnet
Sends the context to your LLM provider for reasoning
Validates any proposed actions through a hard-coded Guardrails layer
Signs and submits approved transactions using keys stored in your OS Keychain

The LLM never sees your private key. The Guardrails layer operates independently of the model. If a transaction violates your limits, it gets blocked — no matter what the model says.

The Tri-Head Architecture

Sigil gives you three ways to interact with your agents:

CLI — Headless commands for scripting, cron jobs, and CI/CD pipelines
TUI — A real-time terminal dashboard built with Ink for live monitoring
Web Dashboard — A local React app for chat, analytics, and visual agent management

All three interfaces connect to the same core over WebSockets. Every thought, action, and transaction syncs in real-time.

What Makes Sigil Different

Feature	Sigil	Traditional Wallets
Agent autonomy	Continuous reasoning loop	Click-to-transact
Key storage	OS Keychain (`keytar`)	Browser extension / cloud
LLM provider	Your choice (OpenAI, Anthropic, Ollama)	N/A
Safety	Hard-coded guardrails	Manual review
Data storage	Local SQLite	Cloud-dependent

Get Started

npm i -g sigil-wallet
sigil init

That's it. The sigil init wizard walks you through provider setup, wallet generation, and creating your first agent.
