# FAQ / Troubleshooting

<details>

<summary>What assets can I use as collateral?</summary>

* **Currently Supported**: USDC, ETH, BTC.
* **Planned Support**: Tokenized real-world assets (RWAs) such as gold, treasury bonds, and other liquid, verified assets.
* **Why Multi-Collateral Matters**: Multi-collateral support reduces dependency on a single stablecoin and gives traders more flexibility.

</details>

<details>

<summary>How are liquidations handled fairly?</summary>

* Alto uses **Dutch Auction Liquidations** instead of first-come-first-serve bot races.
* Any participant can bid in the auction, ensuring fairness.
* Surplus collateral (after covering debt + penalty) is always returned to the trader.
* **On-Chain Proof**: All liquidation data is permanently stored on-chain for auditability.

</details>

<details>

<summary>What is Ethical Mode?</summary>

* A **halal-compliant trading mode** designed for Islamic finance and ethical investors.
* Features include:
  * No riba (interest): replaced with flat service fees.
  * No gharar (uncertainty): all risk parameters are disclosed upfront.
  * Only asset-backed, verified markets are listed.
* Traders and LPs can enable/disable Ethical Mode via a toggle.

</details>

<details>

<summary>How do I start trading on Alto?</summary>

* Connect your Web3 wallet (MetaMask, Rabby, Ledger, etc.).

1. Deposit collateral (ETH, BTC, USDC, or supported RWAs).
2. Open a position by selecting the market, leverage, and order type.
3. Monitor your position in the dashboard.
4. Close or adjust your position at any time, then withdraw collateral back to your wallet.

</details>

<details>

<summary>What order types are supported?</summary>

* Market Orders (instant execution).
* Limit Orders (execute at your chosen price).
* Stop Orders (for stop-loss).
* Take-Profit Orders.
* Trailing Stops.
* *Planned Advanced Orders*: Iceberg orders and batch trades.

</details>

<details>

<summary>What risks should I be aware of as a trader?</summary>

* **Leverage Risk**: High leverage magnifies both profits and losses.
* **Liquidation Risk**: Positions below maintenance margin are liquidated.
* **Volatility Risk**: Markets can move quickly; use stop-loss orders.
* **Smart Contract Risk**: Though audited, smart contracts always carry inherent risk.

</details>

<details>

<summary>What risks should I be aware of as a liquidity provider (LP)?</summary>

* **Market Imbalance Risk**: One-sided trading demand can pressure vaults, though Alto mitigates this with auto-hedging.
* **Volatility Risk**: Volatility vaults carry higher exposure but also higher yield.
* **Smart Contract Risk**: Vault contracts are audited but still subject to general DeFi risks.
* **Liquidity Lock Risk**: Vaults may have lockup periods depending on configuration.

</details>

<details>

<summary>How are fees calculated?</summary>

* **Flat Service Fees**: Fixed fees on opening, holding, and closing positions.
* **No Interest Funding**: Replaced by daily flat charges in Ethical Mode.
* **Discounts**: Traders holding or staking $ALTO tokens receive reduced fees.
* **Transparency**: All fees are shown before order confirmation and recorded on-chain.

</details>

<details>

<summary>What happens if oracles fail?</summary>

* Alto uses a **multi-oracle system**:
  * Primary price feeds.
  * Secondary: TWAPs (time-weighted average prices) from DEXs.
  * Failover: Switches automatically if anomalies are detected.
* In case of catastrophic oracle failure, circuit breakers pause trading until stability is restored.

</details>

<details>

<summary>Can I use $ALTO as collateral?</summary>

* Yes. $ALTO can be staked for governance and fee discounts.
* Certain vaults may allow $ALTO as collateral, though risk parameters are stricter to prevent circular exposure.

</details>

<details>

<summary>How is the protocol secured?</summary>

* Multiple independent smart contract audits.
* Bug bounty program with rewards up to six figures.
* Circuit breakers and time-locked upgrades.
* Transparent on-chain governance.

</details>

<details>

<summary>What makes Alto different from other perp DEXs?</summary>

* **Flat fees instead of interest-based funding.**
* **Structured vaults** for LPs (delta-neutral, directional, volatility).
* **Dutch Auction Liquidations** instead of bot-based sniping.
* **Adaptive Leverage** that scales with volatility and user track record.
* **Ethical Mode** — the first halal-compliant option in DeFi perps.
