Introduction

An AI co-signer and onchain security agent for Squads Protocol V4 multisigs on Solana.

Sage is an autonomous second signer on your Squads Protocol V4 multisig vault. It learns how your vault transacts — amounts, recipients, tokens, timing — and screens every pending proposal against that behavioral profile, your policy rules, and external security data before anything lands on-chain.

Safe transactions auto-execute. Borderline ones are surfaced over Telegram for one-tap review. Clearly malicious ones are blocked.

Sage App

Sign in, see your vault portfolio, and send gasless transfers screened on every action.

Technology

Quickstart

Run Sage locally — client, server, and agent — in minutes.

API Reference

Integrate with the Sage server API for sponsoring, queuing, screening, and execution.

Why Sage?

Multisigs solve key management, but they don’t tell you whether a proposal is safe to sign. A co-signer who blindly approves is just a slower single signer. Once a malicious proposal reaches quorum, the funds are gone.

• A drained recipient, a fat-fingered amount, or a freshly-minted honeypot token all look identical to a wallet
• n-of-m signers approve based on trust, not analysis — there is no screening layer between propose and execute
• Agentic wallets need a co-signer that can reason about risk, not just hold a key

Sage is that co-signer. It holds a member key on your Squads vault with Execute permission and refuses to push anything through that fails its checks.

How It Works

Sage adds an AI co-signer to your Squads vault. Every proposal is scored 0–100 against the vault’s learned behavior, your policy rules, and live security feeds before it executes.

Score	Verdict	Action
< 40	APPROVE	Server co-signs and executes the vault transaction immediately
40–70	REVIEW	Deep analysis + Telegram message with ✅ / ❌ / 🔎 buttons
≥ 70	BLOCK	Marked for review with an urgent Telegram alert

Thresholds are configurable per vault.

Sage is fee-sponsored end to end — the server pays rent and fees, so the user never needs SOL to create a vault or send a transfer.
