Safe Interaction with DApps

Introduction

Interacting with decentralized applications (DApps) on Quranium Chain and EVM-compatible networks (e.g., Ethereum, Polygon) requires vigilance to protect your assets. Q Safe Wallet automates critical security features like post-quantum cryptography (SLH-DSA) for Quranium DApps and ECDSA for EVM chains—but your proactive validation is key. This guide explains how to use DApps securely while minimizing risks.


Quranium Chain DApps: Post-Quantum Security

Key Features

Quranium Chain uses SLH-DSA, a quantum-resistant signing algorithm, to future-proof transactions. Q Safe Wallet ensures:

Feature

How It Works

User Action Required

Automatic Network Detection

Wallet switches to SLH-DSA signing when interacting with Quranium DApps.

Confirm the network is "Quranium" before proceeding.

Signature Validation

All transactions are signed with your SLH-DSA private key (derived from your mnemonic).

Keep your mnemonic offline and never share it.

Gas Fee Handling

Gas fees are paid in QRN (Quranium’s native token). Wallet checks balance before submitting.

Ensure sufficient QRN balance for transactions.


EVM-Compatible DApps: Standard Security

Key Features

For EVM chains (Ethereum, Polygon, BSC), Q Safe Wallet uses ECDSA (secp256k1 curve) for signing.

Feature

How It Works

User Action Required

Automatic Chain Detection

Wallet detects EVM chains (e.g., Ethereum, Polygon) and uses ECDSA signing.

Confirm the correct chain (e.g., “Ethereum Mainnet”).

Gas Fee Optimization

Supports dynamic gas tiers (Economy/Fast/Fastest) based on network congestion.

Select appropriate gas tier to avoid failed transactions.

DApp Permissions

Manages token allowances (e.g., ERC-20 approvals) and lets you revoke access.

Periodically revoke unused approvals.


Best Practices for All DApps

1. Verify DApp Authenticity

  • Check URLs: Ensure you’re on the official DApp website (e.g., app.uniswap.org, not uniswaap.com).

  • Audit Smart Contracts: Use block explorers (Etherscan, Quranium Explorer) to confirm contracts are verified.

2. Limit Token Approvals

  • Set Allowance Caps: Approve only the amount needed for the transaction.

3. Confirm Transaction Details

  • Recipient Addresses: Match them to official DApp contracts or known addresses.

  • Slippage Tolerance: Use conservative values (1-3%) to avoid front-running.


Step-by-Step Workflow

Safe Quranium DApp Interaction

  1. Connect Q Safe Wallet:

    • Ensure the DApp URL is correct.

    • Confirm the wallet switches to Quranium Chain.

  2. Review Transaction:

    • Check gas fees in QRN and validate your balance.

    • Confirm SLH-DSA signing is active (look for "Quantum-Safe" badge).

  3. Sign and Monitor:

    • Track the transaction.

Safe EVM DApp Interaction

  1. Connect Q Safe Wallet:

    • Verify the DApp’s domain and chain (e.g., Ethereum Mainnet).

  2. Adjust Gas Fees:

    • Select Economy/Fast/Fastest based on urgency.

  3. Set Allowances:

    • Approve only the amount needed (e.g., 1 ETH, not unlimited).

  4. Sign and Track:

    • Use Etherscan/Polygonscan to monitor progress.


Common Risks & Mitigations

Risk

Mitigation

Phishing DApps

Bookmark trusted DApps and avoid Google ads.

Unlimited Token Approvals

Revoke unused approvals monthly.

Mismatched Network

Double-check the chain (e.g., Quranium vs. Ethereum) before signing.

Malicious Contracts

Reject transactions with unrecognized payloads or unverified contracts.


Troubleshooting

Insufficient Gas Fees (Quranium)

  • Cause: Low QRN balance.

  • Fix: Acquire QRN from a supported exchange.

Pending EVM Transactions

  • Cause: Gas too low for network congestion.

  • Fix: Speed up the transaction with a higher gas tier.

Unrecognized Contract Interaction

  • Cause: Compromised DApp or accidental approval.

  • Fix: Revoke permissions immediately via Q Safe Wallet.


Note :

Q Safe Wallet automates critical security measures, but your attention to detail prevents disasters. Always verify DApp URLs, limit token approvals, and confirm chain settings. Quantum-safe SLH-DSA (Quranium) and battle-tested ECDSA (EVM) protect your transactions—but vigilance is irreplaceable.
