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

This FAQ exists to ensure users understand both the strengths and the limitations of QUSDC clearly.
