About EternaX Labs
EternaX builds the post-quantum authorization and market infrastructure institutions need to protect custody, tokenized assets, and settlement—without forcing one migration path.
Harden existing MPC, HSM, Safe-style, and EVM systems today. Build PQ-native applications on Pluto. Move to post-quantum rails when the operating model requires it.
Mission
Make institutional authorization durable before quantum risk forces an emergency migration.
Add post-quantum controls beneath existing custody, tokenization, and EVM workflows. Keep the provider, platform, chain, and operating model wherever the architecture permits.
Give institutions and developers a PQ-native EVM environment for new assets and applications, with conservative hash-based security, crypto-agility, and market-ready execution as design constraints.
EternaX defines protection control by control. A system is not called post-quantum safe when an ECDSA or EdDSA fallback can bypass the PQ verifier, and chain consensus, immutable contracts, bridges, oracles, recovery keys, and encryption migration remain explicit residual dependencies where applicable.
What is EternaX?
EternaX is a post-quantum infrastructure and research company for institutional digital assets. It is not a custodian or tokenization platform. It builds the authorization software, EVM controls, test infrastructure, and cryptographic architecture that let institutions choose the right migration path for each system.
For existing systems, EternaX provides an integration-native control layer. PQ Custody SDK brings signature-agnostic dual-gate authorization to MPC, HSM, and Safe-style custody. PQ Vault, PQ-ONCHAINID, PQ-Permit, and PQ-4626 extend protection into issuer authority, investor compliance, delegated approvals, and tokenized-vault governance on supported EVM deployments.
For new PQ-native applications, Pluto provides a public EVM-compatible testnet with native SLH-DSA accounts, compact SILMARILS transaction authentication, SLH-DSA and ML-DSA precompiles, PQ-ONCHAINID compliance flows, and dual-gate custody. It makes the full path—from keys and custody to Solidity contracts and regulated assets—available for testing.
Both paths use conservative NIST hash-based SLH-DSA / SPHINCS+ where long-duration authorization matters, while separating policy and threshold authorization from any single signature scheme. That separation preserves cryptographic agility: approved algorithms can change without forcing another custody or application redesign.
The work is grounded in published cryptography, open-source reference implementations, a live public testnet, and institutional exposure research. The goal is practical: define what can be protected now, make the PQ verifier authoritative where deployable, and document the dependencies that remain outside the protection boundary.

Team and Scientific Leadership
EternaX combines post-quantum cryptography, distributed-systems engineering, institutional digital-asset strategy, and market infrastructure experience.
The architecture is anchored in published research and ongoing cryptographic development so custody, application, and protocol controls can evolve as standards and threat models change.
