Quantum-Resilience as a Service.

Post-Quantum Security for Web3

Eterna is the solution for blockchain infrastructure looking to migrate to quantum-safe enviroments or launch new offerings that are quantum-secure and scalable at the core.

Satoshi's private keys aren't sacred. We know the companies who can break them.

Context

A Shift In History

Quantum computers (QCs) are no longer science fiction. Google, Microsoft, Amazon, IBM, and other tech giants already have live QCs. Yet, today's digital infrastructure is totally unprepared.

Post-quantum retrofitting faces hard limits.

Mixing old and new cryptography leads to partial protection, inconsistent tooling, and dangerous trust assumptions.

Upgrade paths remain vague or nonexistent.

Ethereum, Bitcoin, Solana; none have credible, coordinated PQ migration paths.

The Immutability Trap.

Great for trust, but if chains aren't quantum-secured from block 0 it critically compromises them towards inevitable attacks (e.g. the exposure of Satoshi's private keys).

Solution

QRaaS, Powered by an L1

A quantum-resilience layer that plugs into today’s wallets, dApps, DAOs, and rollups—backed by a purpose-built L1 that anchors proofs and heavy PQ verification off-chain.

01
QRaaS for Existing Ecosystems
Eterna upgrades today’s chains with post-quantum security without forcing users to migrate. Our QRaaS layer runs alongside Ethereum, Bitcoin, L2s, and appchains to provide quantum-safe signing, verification, and proof anchoring.
02
Purpose-Built Verification Layer
Our L1 is engineered as a cryptographic engine: optimized for PQ schemes, heavy verification, and advanced primitives, while apps and assets remain on their home chains. Eterna anchors proofs and settlement, instead of competing for liquidity or mindshare.
03
From Wallets to Rollups
Wallets, dApps, DAOs, bridges, rollups, and token wrappers can all tap into Eterna for PQ keygen, signing, verification, and ownership migration. A single, coherent upgrade path instead of fragmented, chain-specific retrofits.

Features

QRaaS Modules & Primitives

Eterna provides a suite of post-quantum modules—wallet SDKs, smart contract verification, DAOs, bridges, rollups, and token wrappers—all powered by our L1 as a cryptographic backbone instead of a competing ecosystem.

Wallet SDK & PQ KeygenDrop-in libraries for wallets and custodians to generate, rotate, and sign with post-quantum keys (e.g. Dilithium) while keeping all UX and control off-chain.

Smart Contract Verification ToolkitOn-chain and off-chain PQ signature verification patterns for EVM and non-EVM chains: do it directly in Solidity (when feasible) or outsource heavy checks to Eterna and submit lightweight proofs.

DAO Voting & Key MigrationPQ-safe voting, delegation, and treasury control with gradual migration from legacy keys to quantum-safe identities—without breaking existing governance contracts.

Bridges & Validator PQ SigningValidator and prover sets sign state, messages, and proofs with PQ keys, while Eterna handles verification and slashing logic so legacy chains do not need new precompiles.

Rollup & L2 Security ModuleRollup sequencers and fraud-proof systems integrate PQ-safe state roots and challenge flows, with custom verification running on Eterna or on controlled L2s.

Token Wrappers & PQ OwnershipContracts that register PQ-safe ownership for ERC20s, NFTs, RWAs, and more—enforcing control via PQ keys while assets remain where liquidity already lives.
