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, notuniswaap.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
Connect Q Safe Wallet:
Ensure the DApp URL is correct.
Confirm the wallet switches to Quranium Chain.
Review Transaction:
Check gas fees in QRN and validate your balance.
Confirm SLH-DSA signing is active (look for "Quantum-Safe" badge).
Sign and Monitor:
Track the transaction.
Safe EVM DApp Interaction
Connect Q Safe Wallet:
Verify the DApp’s domain and chain (e.g., Ethereum Mainnet).
Adjust Gas Fees:
Select Economy/Fast/Fastest based on urgency.
Set Allowances:
Approve only the amount needed (e.g., 1 ETH, not unlimited).
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.
