# Thales Vaults
[**Thales Vaults**](https://thalesmarket.io/vaults) **are products that accepts user deposits and uses those deposits on automated trading strategies on the Thales Marketplace.**
Vaults are currently available using **sUSD** **on Optimism** and **USDC** **on Arbitrum** **.**
The Thales vaults work by allowing anyone to deposit USD in a certain vault which is then utilized in cycles of **1-week trading rounds** that execute specific trading strategies.
{% hint style="warning" %}
USD can be deposited by the user at any time, but it **will only start getting utilized at the start of the subsequent trading round.** \
\
A depositor can request a withdrawal of his share at any time, but his share **will be unlocked and withdrawable only when the current trading round ends.**
{% endhint %}
Thales Vaults can be found in the sidebar menu of the dapp, or by using this direct link: \

Depositors can choose from different strategies with detailed descriptions of parameters such as utilization rate and maximum risk. Select a vault to view the specifics of that strategy and deposit USD to participate.
### **Vault Strategies**
Strategies vary from targeting positions with odds above or below a certain threshold, or by including positions available at a certain discount.
1. [**Discounts vault**](https://thalesmarket.io/vaults/discount-vault)**:** Buys positions that have **more than 50% calculated probability** and are available at a **discount larger than 3%**.
2. [**Degen Discount vault**](https://thalesmarket.io/vaults/degen-discount-vault)**:** Buys positions that are available for **more than a 2% discount,** without taking into account the probability of the position.
3. [**Safu Discount vault**](https://thalesmarket.io/vaults/safu-discount-vault)**:** Buys positions that have **more than 75% calculated probability** and are available at **any discount** (1% or higher).
Vaults are defined by trading strategy as well as the following variables:
* Utilization rate
* Price lower limit and upper limit
* Max Skew impact
* Max allocation on a single market
* Minimum amount on a single trade and minimum deposit
* Max total deposit and max users in the vault (Vault Caps)
{% hint style="info" %}
Vault will be capped initially, with increases subject to community governance.
Currently Vault Caps on **Optimism** are **100 users** and **100,000 sUSD** total.
On **Arbitrum** vaults are capped at **100 users** and **50,000 USDC** total.
{% endhint %}
### Main value propositions of Thales Vaults
1. **Passive trading**. There’s no need to withdraw and/or deposit for every round. If you keep your collateral inside a vault, it will automatically roll over (plus the winnings or minus the losses of the previous round) to the next round.
2. **Vaults have lower Trading Fees (from 3% to 0.5%).** Trader's benefit from [TIP-105](https://github.com/thales-markets/thales-improvement-proposals/blob/main/TIPs/TIP-105.md), which effectively gives more edge to Thales Vaults and their strategies, compared to a user manually executing the same trades.
3. The full amount deposited into the vaults *(be it* [*Overtime*](https://overtimemarkets.xyz/#/vaults) *or* [*Thales*](https://thalesmarket.io/vaults)*)* by users counts toward the [**gamified staking “Protocol volume” bonus**](https://thalesmarket.io/token?activeButtonId=rewards).
