Frequently Asked Questions (FAQ)

General Questions

What is QUSDC?

QUSDC is a fully reserved, decentralized stablecoin issued natively on the QIE blockchain.

Each QUSDC represents 1 USDC deposited into the system, enforced by smart contracts. QUSDC functions as an on-chain receipt token that proves USDC backing on a 1:1 basis.

---

What does “on-chain receipt token” mean?

An on-chain receipt token means:

• QUSDC is issued only when USDC is deposited

• QUSDC represents a claim on that deposited USDC

• When QUSDC is burned, the USDC is released

In simple terms:

QUSDC is proof that USDC has been locked in the system.

---

Is QUSDC the same as USDC?

No.

• USDC is issued by Circle and backed by fiat dollars held off-chain.

• QUSDC is a protocol-issued token on QIE that represents deposited USDC value.

QUSDC depends on USDC for backing, but its issuance, burning, and accounting are enforced by smart contracts on QIE.

---

Is QUSDC pegged to the US Dollar or USDC?

QUSDC is pegged 1:1 to USDC, and indirectly to the US Dollar through USDC.

1 QUSDC = 1 USDC

The peg is enforced by protocol rules, not market incentives.

---

Backing & Stability

How is QUSDC backed?

QUSDC is backed 100% by USDC.

• Every QUSDC in circulation corresponds to USDC locked as reserves

• Tokens are minted only when reserves are deposited

• Tokens are burned when reserves are redeemed

There is no partial or fractional backing.

---

Can QUSDC be over-minted?

No.

QUSDC cannot be minted unless the required USDC backing is deposited. Smart contracts enforce a strict 1:1 minting rule.

There is no admin key or discretionary minting capability.

---

Is QUSDC algorithmic?

No.

QUSDC:

• Does not use algorithms

• Does not rely on incentives

• Does not rebalance supply

• Does not use price oracles

Stability is achieved through full reserve backing, not algorithmic mechanisms.

---

Can QUSDC lose its peg?

Under normal protocol operation, QUSDC maintains its peg because:

• It cannot exist without USDC backing

• Redemption always burns QUSDC and releases USDC

However, QUSDC indirectly inherits risks associated with USDC itself (issuer, regulatory, or fiat-layer risks).

---

Decentralization & Control

Is QUSDC centralized?

QUSDC is trust-minimized, not centrally controlled.

Decentralized aspects:

• Permissionless minting and burning

• Smart contract–enforced rules

• Public on-chain transparency

Centralized dependencies:

• USDC issuance and fiat reserves exist off-chain

QUSDC removes centralized control where blockchain technology can, and is transparent where it cannot.

---

Who controls QUSDC?

No single party controls QUSDC supply.

• Smart contracts control minting and burning

• Supply and reserves are publicly verifiable

• No entity can mint unbacked QUSDC

Protocol upgrades, if any, are expected to follow transparent governance processes.

---

Can QUSDC be frozen?

QUSDC itself does not include discretionary freezing logic.

However:

• USDC (the backing asset) may be subject to issuer or regulatory actions

• This is an inherited risk from USDC, not QUSDC-specific behavior

This dependency is openly disclosed.

---

Minting & Redemption

Who can mint QUSDC?

Anyone can mint QUSDC.

Minting is:

• Permissionless

• Open to all users

• Enforced by smart contracts

The only requirement is depositing the required USDC backing.

---

Is there a minimum or maximum mint amount?

This depends on protocol parameters and UI constraints. At the protocol level, minting follows simple 1:1 rules without discretionary limits.

---

How do I redeem QUSDC?

To redeem QUSDC:

1. QUSDC is returned to the protocol

2. QUSDC is burned

3. The corresponding USDC is released

Redemption follows the same deterministic rules as minting.

---

Is redemption always available?

Redemption is always available as long as protocol conditions are met.

There is no redemption queue, no manual approval, and no discretionary delay imposed by the protocol.

---

Fees & Costs

Are there fees for minting or burning QUSDC?

Protocol-level fees may apply depending on:

• Network transaction fees

• Platform-specific configurations

QUSDC itself does not rely on hidden fees or spread-based mechanisms.

---

Does QUSDC generate yield?

No.

QUSDC is not a yield-bearing asset by default.

If users want yield, they may use external DeFi protocols at their own discretion.

---

Risk & Security

Is there liquidation risk?

No.

QUSDC:

• Is fully collateralized

• Uses stable collateral

• Does not involve borrowing or leverage

There are no liquidation thresholds or margin calls.

---

What happens if QIE network is down?

If the QIE network experiences downtime:

• Transactions may be delayed

• QUSDC state remains intact on-chain

Once the network resumes, QUSDC continues operating normally.

---

Has QUSDC been audited?

Audit status depends on project disclosures and publications. Users should always refer to official documentation for audit reports and updates.

---

Ecosystem & Usage

Where can I use QUSDC?

QUSDC can be used across the QIE ecosystem, including:

• Wallets

• DEXs

• DeFi protocols

• Payment applications

• Developer platforms

---

Is QUSDC bridged to other chains?

QUSDC itself is not bridged.

Only the backing USDC value may move across chains when users choose to bridge.

This design minimizes systemic risk.

---

Is QUSDC suitable for long-term holding?

QUSDC is designed for:

• Stability

• Predictability

• Capital preservation

However, users should always assess risks related to USDC, regulation, and blockchain infrastructure.

---

Final Clarifications

Is QUSDC meant to replace QIE’s native token?

No.

QUSDC complements the QIE native token by serving as a stable unit of account, while native tokens continue to handle governance, security, and incentives.

---

What is the main goal of QUSDC?

The main goal of QUSDC is to provide:

A transparent, fully backed, on-chain dollar for the QIE ecosystem — enforced by smart contracts, not trust.

---

Where can I learn how to mint or redeem QUSDC?

Step-by-step user guides are provided in the User Guides section of this documentation.

---

Summary

QUSDC is designed to be:

• Simple

• Transparent

• Fully backed

• Trust-minimized

• Ecosystem-native
