# Instanodes Rolls Out Post-Quantum Account Tooling for Ethereum and Solana

The Web3 infrastructure firm launched hash-based signature architectures and quantum-readiness audits for EVM networks and Solana.

## At a glance

- **What happened:** Instanodes launched post-quantum account engineering and readiness assessment services using hash-based signatures for EVM networks and Solana on Nov. 3, 2026.
- **Why it matters:** The implementation allows institutions to reduce reliance on conventional elliptic-curve signatures at the account level before quantum hardware threatens standard cryptography.
- **Who is affected:** Crypto exchanges, digital asset custodians, wallet developers, and blockchain protocols operating on EVM chains and Solana.
- **Takes effect:** 2026-11-03
- **What's next:** Client onboarding and technical evaluations of quantum-resistant signature architectures across more than 50 supported networks.
- **Status:** announced
- **Primary source:** [Instanodes Introduces Post-Quantum Accounts for Ethereum and Solana](https://www.prnewswire.com/news-releases/instanodes-introduces-post-quantum-accounts-for-ethereum-and-solana-302927775.html) — PR Newswire

## Key points

- Instanodes deployed post-quantum account implementations using hash-based digital signatures for EVM-compatible chains and Solana.
- The tooling leverages ERC-4337 smart accounts on Ethereum and custom program-level verification on Solana without modifying Solana's native Ed25519 layer.
- The expansion includes quantum-readiness assessments and migration roadmaps for crypto exchanges, custody providers, and protocols.

## Editorial remark

- **Context:** Mainstream blockchain architectures rely heavily on elliptic-curve cryptography, which theoretical fault-tolerant quantum computers could compromise. Research published by Google Quantum AI and IonQ earlier in 2026 renewed scrutiny around these long-term cryptographic dependencies.
- **Impact:** Custodians, centralized exchanges, and smart-contract protocols on EVM networks and Solana can now evaluate and test non-elliptic-curve authorization models without waiting for native protocol-level hard forks.
- **Watch:** Adoption rates among enterprise custodians and institutional wallet developers for ERC-4337 post-quantum signers, alongside further fault-tolerant quantum resource estimates from industry researchers.

Blockchain infrastructure provider Instanodes announced post-quantum account engineering and readiness assessment services for Ethereum Virtual Machine-compatible networks and Solana on Nov. 3, 2026 [1]. The offering introduces hash-based digital signature implementations designed to insulate account-level transaction authorization from theoretical vulnerabilities posed by future quantum computing hardware [1]. At the time of writing, $ETH traded at $2,264 and $SOL traded at $92.46 amid broader market consolidation.

The deployment specifically targets asset-level authorization rather than underlying base-layer consensus [1]. On EVM chains, Instanodes utilizes programmable smart-account frameworks—notably ERC-4337—to embed custom signature-validation schemes that operate independently of legacy elliptic-curve cryptography [1]. For Solana, the architecture deploys custom program-level verification and asset-control modules [1]. Instanodes noted that its Solana implementation does not alter the network's native transaction-signature infrastructure, which continues to rely on the Ed25519 standard [1].

## Shifting Focus to Cryptographic Migration

The initiative addresses long-term structural concerns regarding widely deployed public-key algorithms [1]. Instanodes cited recent resource-estimate studies released by Google Quantum AI in March 2026 and IonQ in September 2026, which analyzed the timelines under which fault-tolerant quantum machines could challenge classical cryptographic safeguards [1]. These emerging threats have prompted protocol developers and custodians to explore post-quantum defenses, mirroring wider efforts across ecosystem roadmaps such as [Ethereum's post-quantum roadmap](https://basisdesk.news/news/ethereum-post-quantum-cryptography-roadmap) and [Bitcoin's BIP 360 proposal](https://basisdesk.news/news/bitcoin-developers-propose-bip-360-quantum-resistance).

Alongside the account framework, Instanodes launched quantum-readiness audits to help exchanges, institutional custodians, and decentralized protocols identify vulnerable cryptographic dependencies across existing wallets and smart contracts [1]. The company stated it will also deliver custom cryptographic engineering, building out verification contracts and structured migration pathways for enterprise clients operating across more than 50 supported networks [1].
