# USDx Quickstart

Use this page to choose the right path before interacting with Axis.

{% hint style="warning" %}
Verify the current contract addresses and current protocol parameters before signing. A token symbol or address shared through an unofficial channel is not proof that a contract is part of Axis.

## Choose what you want to do

### Hold USDx

USDx is the synthetic-dollar token. Holding USDx alone does not earn the staking-vault yield. Before acquiring it, understand the [price-stability pathway](/usdx-the-synthetic-dollar/peg-stability.md) and [risk profile](/risk/risk-overview.md).

### Stake USDx

Staking deposits USDx into the vault and returns sUSDx. As funded rewards vest into the vault's accounted assets, each sUSDx position becomes redeemable for more USDx and the exchange rate rises over time. Axis's structural edge is cross-venue and cross-asset fragmentation; funding is one component (and can be the larger share in a given period), with current attribution on the Transparency Dashboard. Yield is variable and is not guaranteed.

Unstaking is not instant. It is an asynchronous redeem request (ERC-7540): you call `requestRedeem`, which burns your shares and reserves the corresponding assets. The request must first clear the cooldown, currently **7 days**, then be serviced by an operator (`serviceRedemptions`) before it becomes claimable; only then can you claim USDx. The cooldown is the eligibility delay on that request, not a simple setting on an otherwise instant unstake.

For contract-level steps, see [Stake & Unstake USDx](/susdx-the-rewards-vault/stake-and-unstake.md).

### Mint or redeem USDx

Minting and redemption use EIP-712 signed orders submitted by authorized operators to the USDxMarket. The order states the collateral and USDx amounts; it must pass signature, deadline, nonce, asset, route, authority, and capacity checks before it can settle.

For the integration flow, see [Mint & Redeem USDx](/usdx-the-synthetic-dollar/mint-and-redeem.md).

## Before every transaction

1. Verify the address on [Contract Addresses](/reference/contract-addresses.md).
2. Read the wallet prompt, including token, amount, spender, and network.
3. If you may need near-term liquidity, plan for the sUSDx async exit: a redeem request must clear its 7-day cooldown and be serviced before USDx is claimable.
4. Do not infer a guaranteed dollar exit price from the sUSDx vault exchange rate.
5. Consider whether you can tolerate a delay, depeg, or loss.

## Understand your exit path

| Position | Immediate next asset                                                                                                             | Additional step for collateral |
| -------- | -------------------------------------------------------------------------------------------------------------------------------- | ------------------------------ |
| sUSDx    | Open an async redeem request (`requestRedeem`); once the 7-day cooldown elapses and an operator services the request, claim USDx | Submit a USDx redemption order |
| USDx     | USDx                                                                                                                             | Submit a USDx redemption order |

Secondary-market trading may offer another path, but its price and available liquidity are external to the protocol contracts and are not guaranteed.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.axis.to/start-here/quickstart.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
