Mohali, India, November 3, 2026 / PRNewswire / -- A blockchain infrastructure service provider that offers over 50 blockchain networks, dedicated nodes, validators, and Rollup infrastructure, Instanodes announced today that it has launched a post-quantum account engineering solution for Ethereum Virtual Machine (EVM) compatible networks and Solana. The expanded services also include quantum readiness assessments and customized cryptographic engineering services, targeting enterprises that are evaluating the security architecture of their existing accounts.
Prepare a blockchain account for future quantum risks
Blockchain accounts currently rely primarily on elliptic curve cryptography for transaction authorization. However, advancements in quantum computing research have raised concerns about the long-term security of existing blockchain architectures. Research published by Google Quantum AI in March 2026, as well as that published by IonQ in September 2026, updated resource estimates and explored how future fault-tolerant quantum computers might threaten widely used cryptographic methods.
For enterprises managing digital assets, these developments highlight the necessity of assessing existing blockchain security solutions and preparing for potential cryptographic vulnerabilities. Wallets, hosting platforms, smart contracts, and blockchain protocols may all contain cryptographic dependencies that require evaluation and migration planning. Preparing for quantum-resistant cryptography involves assessing account architectures, signature verification, key management, and asset authorization mechanisms.
Implementation for Ethereum and post-quantum accounts of Solana
Instanodes indicates that hash-based digital signatures have been used, and post-quantum account implementations have been developed and tested for Ethereum and Solana for account-level authorization. These implementations are designed to reduce the reliance on traditional elliptic curve signatures for asset authorization at the account level, and to adjust the verification mechanisms according to the execution environment of each blockchain.
On Ethereum, post-quantum signature verification can be integrated into the programmable smart account architecture, including ERC-4337 which supports custom signature verification logic. On Solana, a similar account design requires customized program-level signature verification and asset control mechanisms. However, these implementations do not replace the native transaction signature infrastructure of Solana, which continues to use Ed25519.
Instanodes indicates that through these implementations, the company aims to assist exchanges, custodian institutions, and blockchain protocols in evaluating alternative cryptographic solutions for account security, and to prepare the infrastructure for the evolving capabilities of quantum computing.
Quantum readiness services for blockchain enterprises
Instanodes is expanding its blockchain infrastructure services to help enterprises assess cryptographic vulnerabilities and prepare for emerging security requirements. Its specialized services include:
- Post-quantum accounts:Designed for compatibility with both EVM and Solana networks, this implementation is based on hash signatures and is intended to be integrated into wallet, hosting, and protocol architectures.
- Quantum Readiness Assessment:Review cryptography dependencies, identify components that are vulnerable to quantum computing, and develop a structured migration roadmap.
- Custom Password Engineering:Develop hash-based signature systems, on-chain verification mechanisms, implement ERC-4337 smart accounts, and customize Solana programs.
- Blockchain infrastructure:RPC endpoints covering over 50 networks, dedicated nodes, validator infrastructure, and dedicated blockchain environments.
Companies that are evaluating their post-quantum cryptography risk exposure or planning to strengthen their blockchain infrastructure can contact the Instanodes engineering team to discuss their technical requirements and learn about related blockchain development services, according to the company.
