QANplatform, a blockchain platform focused on quantum-resistant security, announced the successful completion of a cybersecurity audit—conducted by Hacken—of its QAN XLINK protocol. This cross-signer protocol integrates Ethereum-compatible wallets with quantum-safe keypairs, addressing the growing threat of quantum computing attacks on blockchain networks, where an estimated 6.65 million Bitcoin addresses and over 65% of Ether have exposed public keys. Utilizing NIST’s ML-DSA (FIPS 204) lattice-based Post-Quantum Cryptography algorithm, QAN XLINK provides a guaranteed migration path to a quantum-safe Web3 ecosystem, delivering both Ethereum compatibility and enhanced security.
QAN XLINK and Quantum-Safe Security
QANplatform has developed QAN XLINK, a cross-signer protocol designed to integrate Ethereum-compatible wallets with quantum-safe keypairs. This addresses the growing threat of quantum computing attacks on blockchains, where exposed public keys become vulnerable. Hacken, a blockchain security firm, recently completed a comprehensive cybersecurity audit confirming QAN XLINK’s ability to protect against these future attacks. Approximately 6.65 million Bitcoin addresses (25% of the total supply) and over 65% of all Ether currently have exposed public keys, highlighting the urgency of this solution.
QAN XLINK utilizes ML-DSA, a lattice-based Post-Quantum Cryptography (PQC) algorithm recommended by NIST (FIPS 204), to provide a 100%-guaranteed safe migration path for the post-quantum era. QANplatform is unique in delivering both Ethereum compatibility and this guaranteed quantum-safe migration. Leading organizations like NIST, the Federal Reserve, and BlackRock are warning of the imminent vulnerability, coinciding with the recent issuance of NIST’s post-quantum cryptography standard and updates to BlackRock’s Bitcoin ETF prospectus.
The development of QAN XLINK positions QANplatform as a pioneer in quantum-safe Web3 security. It’s the first blockchain to offer this combination of features and has already been implemented by one EU country in 2024. QANplatform is a member of the Linux Foundation’s Post-Quantum Cryptography Alliance (PQCA) and actively advocates for blockchain adoption within the European Union through Blockchain for Europe, joining in October 2025. Developers can now apply to test the QAN XLINK desktop app.
The Growing Threat of Quantum Computing
The growing threat of quantum computing poses a significant risk to existing blockchain networks, with estimates showing around 6.65 million Bitcoin addresses (approximately 25% of the total supply) and over 65% of all Ether having exposed public keys vulnerable to future quantum attacks. This vulnerability stems from the fact that even a single transaction reveals a wallet’s public key, potentially allowing theft once quantum computers become powerful enough to break current encryption. Organizations like NIST, the Federal Reserve, and BlackRock are warning of this impending vulnerability.
QANplatform is addressing this threat with QAN XLINK, a cross-signer protocol designed to integrate with Ethereum-compatible wallets like MetaMask and Trust Wallet. This protocol utilizes ML-DSA, a lattice-based Post-Quantum Cryptography (PQC) algorithm recommended by NIST (FIPS 204), to provide a 100%-guaranteed safe migration path for the post-quantum era. QANplatform claims to be the only blockchain delivering both Ethereum compatibility and this guaranteed quantum-safe migration.
Hacken, a blockchain security firm, completed a comprehensive cybersecurity audit of QAN XLINK, bolstering confidence in its ability to deliver forward-looking security. The audit comes at a time when NIST has issued its post-quantum cryptography standard and BlackRock updated its Bitcoin ETF prospectus to highlight the growing quantum risk. QANplatform is a member of the Linux Foundation’s Post-Quantum Cryptography Alliance (PQCA) and has already implemented its quantum-resistant technology in one EU country.
the quantum threat is no longer a distant concern, it demands proactive preparation for the whole web3 ecosystem.

QANplatform and Hacken’s Cybersecurity Audit
QANplatform recently completed a comprehensive cybersecurity audit of its QAN XLINK protocol, performed by Hacken. This protocol is designed to integrate Ethereum-compatible wallets with quantum-safe keypairs, addressing the growing threat of quantum computing attacks on blockchains. The audit confirms QAN XLINK’s ability to protect against these attacks, a concern highlighted by organizations like NIST, the Federal Reserve, and BlackRock, who warn of impending vulnerabilities in existing systems.
QAN XLINK utilizes the NIST-recommended ML-DSA (FIPS 204) lattice-based Post-Quantum Cryptography (PQC) algorithm, providing what QANplatform claims is a 100%-guaranteed safe migration path to the post-quantum era. The source material notes that approximately 6.65 million Bitcoin addresses (25% of the total supply) and over 65% of all Ether currently have exposed public keys, making them susceptible to future quantum attacks.
Hacken’s audit comes at a crucial time, coinciding with the NIST issuing its post-quantum cryptography standard and BlackRock updating its Bitcoin ETF prospectus to acknowledge quantum risk. QANplatform positions itself as unique, being the only blockchain delivering both Ethereum compatibility and a guaranteed quantum-safe migration. Developers can currently apply to test the QAN XLINK desktop app, signaling a move towards wider adoption of this quantum-resistant technology.
