Instanodes launches post-quantum accounts for Ethereum and Solana users

[Poppy5]

Crypto infrastructure providers are starting to offer quantum safe options. Quantum Zeitgeist reports that Instanodes, a node and RPC provider supporting more than 50 blockchains, is launching post-quantum accounts using hash based signatures for Ethereum compatible chains and Solana

On Ethereum, the post-quantum signature checks are built into ERC-4337 smart accounts, which allow custom rules for how transactions are approved

Solana's native transactions still use Ed25519 signatures, so Instanodes adds post-quantum checks at the program level instead

The company also offers quantum readiness assessments, migration roadmaps and custom cryptography engineering. The article cites resource estimates from Google Quantum AI in March 2026 and IonQ in September 2026, but does not name the signature scheme used, and there are no audits, pricing or executive quotes

Smart accounts are a practical way to add post-quantum protection without waiting for full network upgrades. Hash based signatures are well understood and considered very secure. Independent audits will be essential before anyone trusts large sums to these accounts

Would you move crypto into a post-quantum account? And should infrastructure providers lead on quantum safety?

Smart accounts are a clever workaround. Users can get quantum protection now without waiting for Ethereum's full upgrade. That is useful for cautious holders

Audits before trusting real money is essential. New cryptography implementations often have bugs. Wait for independent reviews

Wallet providers might adopt it if audits go well. Adoption depends on trust

Hash based signatures are larger than current ones, which costs more gas. Users may pay higher fees for safety

That trade off matters on Ethereum. Layer two networks could help

Fifty supported chains gives Instanodes wide reach. If the product works, adoption could spread

Early days, though. Early movers often set standards. Instanodes wants to be first. Being first is not always enough

[Wrench36]

No signature scheme named is a big gap. Hash based signatures come in several types

Details matter in cryptography. Details will decide trust

[LAKnight_Chokeslam]

Solana using Ed25519 natively makes it harder to protect. Program level checks help, but the base layer is still vulnerable. A network upgrade will eventually be needed

Workarounds only go so far. Gas costs will be a barrier

Infrastructure providers offering readiness assessments shows a market is forming. Projects want to know their exposure

Consulting will be in demand. Consulting services are a smart business
