Core Features
Building the Quantum-Resilient Backbone of Web3
QBT powers next-generation infrastructure with post-quantum security, cross-chain interoperability, and lightning-fast consensus — shielding today’s assets, messages, and identities from Harvest Now, Decrypt Later (HNDL) attacks.
HNDL Defense (Harvest Now, Decrypt Later)
Pre-encrypts your data with quantum-safe keys to stop future decryption—even if harvested today.
HNDL-Proof Data Anchoring
Ensure personal and business data is secured today against quantum decryption tomorrow — before it’s too late.
Zero-Retention Secure Messaging
Send encrypted messages that remain private even if intercepted and stored — thanks to post-quantum security layers.
Quantum-Resistant by Default
Every signature, message, and contract is secured against future quantum decryption from the moment it’s created.
Sub-Second Finality
Experience lightning-fast transaction settlement thanks to our optimized validator layer.
Cross-Chain Interoperable
Bridge assets and contracts seamlessly across EVM and non-EVM chains.
Deflationary Mechanics
Supply-reducing features like burns and capped issuance strengthen long-term value.
Proactive Threat Defense
Designed to block quantum threats like HNDL with formal verification and future-proof encryption from day one.
NFT + Token Migration
One-click migration of NFTs and QBT holdings to the Quantum Resilience Network.
Our Mission
To build the foundational layer for a quantum-secure Web3 — enabling individuals, developers, and enterprises to operate safely, seamlessly, and without compromise across tomorrow’s digital ecosystems. QRB doesn’t just react to quantum threats — it prevents the future compromise of today’s data, securing identities, transactions, and records from harvest-now-decrypt-later (HNDL) attacks.
Dive deeper into the QBT vision and join a fast-growing community building the quantum-secure future of Web3.

Frequently Asked Questions
Use a decentralized wallet compatible with WalletConnect, such as MetaMask or Trust Wallet. Make sure your wallet is set to the Ethereum network (ERC-20).
Step 2: Fund Your Wallet with ETH
Ethereum (ETH) is required for transaction gas fees, even if you plan to purchase QBT using USDT or USDC. Acquire ETH via platforms like Coinbase, Binance, or any reputable exchange, and transfer it to your wallet.
Step 3: Visit the QBT Presale Portal
Open your web browser and navigate to our official presale portal. Click the "Connect Wallet" button to link your wallet.
Step 4: Select Payment Method
Choose to pay using ETH, USDT, or USDC by selecting the respective option on the presale dashboard.
Step 5: Enter Purchase Amount
Input the amount of ETH, USDT, or USDC you want to use. The dashboard will display the number of QBT tokens you’ll receive. Confirm your selection and click "Buy".
Step 6: Approve and Confirm the Transaction
Verify transaction details in your wallet, including the amount and recipient address. Confirm the transaction and wait for the Ethereum network to validate it.
For USDT/USDC payments: You may need to approve the token contract in a separate step before completing the final transaction.
Step 7: Claim Your Vested Tokens
After the presale ends, your purchased QBT tokens will be available to claim according to the vesting schedule. Vesting starts after the presale, with a 30-day cliff and a 180-day vesting period. You can claim vested tokens from the portal as they become available.
Important Notes:
- Double-check all wallet addresses and payment details to avoid errors.
- When paying with USDT or USDC, ensure both "Approval" and "Buy" transactions are completed.
- QBT tokens are only available on the official presale portal during the presale phase.
- Be cautious of counterfeit tokens on DEXs.
