# Polaris Multi-Signature Wallet

**Polaris uses multi-signature (multi-sig) technology to enable trading and keep your assets safe.**

Multi-Sig wallets provide an extra layer of security by requiring the approval of multiple signers for any withdrawal of funds.

Polaris uses a 2-3 escrow style Multi-Signature Wallet, meaning that three signers are involved, and two of them must agree and provide a signature to authorize a withdrawal.

**Key Takeaways:**

* A Multi-Sig requires the approval of multiple signers to approve any withdrawal of funds.
* 2-3 Multi-Sig: The multi-sig wallet has three signers. To take money out, two of these three signers must agree and provide a signature.
* Multi-Sigs are one of the most commonly used ways of storing assets securely.

### How Polaris uses 2-3 Multi-Sig wallets:

**Withdrawal process:**

* You provide a signature and send it to Polaris
* Polaris verifies if the requested withdrawal amount falls within the limits of both the Multi-Sig and on-chain balances and the Polaris balances post-trading.
* Polaris adds their signature and proceeds with transferring the funds out of the multi-sig.
* **Withdrawal fees are paid by the exchange.**
* If the withdrawal amount requested is not valid, the withdrawal is rejected

**Settlement process:**

* Either party can request a settlement at any time, usually based on who needs the funds first.
* Polaris may settle user balances at their discretion. This may happen while users are offline.
* Likewise, users can request a settlement at any time. For example, if you wish to withdraw your funds or keep your account organized and up-to-date.
* For these reasons, Polaris utilizes the services of a third-party “escrow” signer. This signer double-checks trades and balances and can sign transactions in the absence of the user.
* At this time, on-chain settlement fees are paid by Polaris and the escrow signer.
