# Overview

> What you can do with the Sage app.

Sage is a Solana smart wallet built on a Squads V4 multisig vault, with an AI co-signer screening every outgoing transfer. You sign in, see your vault portfolio, and send — every transaction passes through the same screening pipeline before it executes.

## The Vault

When you first sign in with Privy, Sage deploys a Squads V4 multisig for you. The vault has two members:

| Member                    | Permission | Role                                     |
| ------------------------- | ---------- | ---------------------------------------- |
| **You** (embedded wallet) | `all`      | Propose, vote, execute                   |
| **Sage** (server keypair) | `Execute`  | Co-sign and broadcast approved transfers |

The multisig threshold is `1` — your proposal plus Sage's execution is all it takes. Sage never *initiates* a transfer; it only screens what you propose and executes what passes.

<Note>
  The vault address is derived deterministically from your wallet, so logging in from a new device resolves the same vault — no migration, no re-deploy.
</Note>

## Screening Modes

| Mode    | Behavior                                                           |
| ------- | ------------------------------------------------------------------ |
| **ON**  | Full pipeline — APPROVE / REVIEW / BLOCK on every transfer         |
| **OFF** | Plain multisig — proposals are queued and executed without scoring |

Toggle anytime from Telegram (`screening on` / `screening off`) or the app settings.

## Gasless & Sponsored

Every transaction on Sage is fee-sponsored. The server signs as fee payer and pays all account rent (multisig creation, vault transaction, proposal accounts) — so you never need SOL to create a vault or send a transfer. Rent from completed proposals is automatically reclaimed back to the server.
