Frequently Asked Questions

QuantumBit Token (QBT) powers the Quantum Resilience Network. It's used for governance and as a bridge asset to migrate from legacy blockchains to our quantum-secure mainnet.
Step 1: Prepare Your Wallet
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.
Yes. While QBT offers advanced quantum-resistant security, its market value can fluctuate. Always research carefully and invest only what you can afford to lose.
QBT has a fixed 10 billion supply: 40% treasury, 20% team (with 6-month cliff + 3-year linear vesting), 15% community, 15% presale, and 10% liquidity.
Yes. After migrating to PQ-QBT, you’ll be able to stake your tokens to earn rewards and support consensus. Staking begins with mainnet launch in Q1 2027.
Migration will be supported on Ethereum, BSC, and Polygon at launch. More chains may be added via governance.
You’ll burn your ERC-20 QBT using the QuantumBridge and receive PQ-QBT on the mainnet at a 1:1 ratio. This is verified with Dilithium cryptography and handled via a user-friendly portal.
You’ll still own your QBT on Ethereum, but it won't benefit from quantum security. Migration can still be completed later — fallback windows may be opened through governance votes if needed, ensuring no long-term lockout.
Yes. All contracts will be audited by firms like CertiK or Quantstamp before mainnet. Reports will be published on our site and GitHub.
QBT itself is an ERC-20 bridge token. Quantum resistance is achieved when QBT is migrated to PQ-QBT on the QRB mainnet, where all transactions and smart contracts are secured by NIST-approved post-quantum algorithms like Dilithium and SPHINCS+. This ensures immunity from Harvest Now, Decrypt Later (HNDL) attacks.
QRB prevents future compromise of today’s encrypted data by using NIST-approved post-quantum cryptography. Sensitive transactions, NFT metadata, and identities anchored on the QRB mainnet are safe from actors who might store data now and attempt to decrypt it once quantum computers become viable.
QBT (ERC-20) works with MetaMask, Trust Wallet, Ledger, and Trezor. After migration, PQ-QBT will also be accessible through native mobile wallets.
QBT will be available on decentralized exchanges like Uniswap shortly after the presale ends. Listings on centralized exchanges are planned around the mainnet launch in 2027, subject to ecosystem maturity and liquidity support.
Unlike QRL, which lacks smart contract functionality, or Algorand, which uses a hybrid approach to quantum resistance, the QRB ecosystem enables full DeFi and NFT support secured by post-quantum cryptography — with QBT acting as the migration bridge from legacy chains.
Use the QuantumBridge NFT Portal to lock your Ethereum NFTs (ERC-721/1155). It creates SPHINCS+ proofs and mints quantum-safe PQ-NFTs on the mainnet.
Yes. We use SPHINCS+ anchoring to preserve metadata, traits, IPFS hashes, and royalty settings — including OpenSea creator fees.
Migration of NFTs from other blockchains will be supported in the future. Stay tuned for updates.
Your original NFT is locked in a time-locked smart contract. You retain ownership and can reverse the migration within 30 days if needed.
Yes. You'll pay standard gas fees plus a small migration fee to cover permanent metadata storage on quantum-secure IPFS clusters and verification services. Final rates will be set by governance closer to mainnet.
Visit our official website and follow our social media channels for announcements. Technical documentation, audits, and roadmap progress will be available on GitHub and the Docs portal.
