PQC gateway on Solana

BridgeBaseAI said it has opened a live beta for a post-quantum cryptography gateway on Solana, adding quantum-resistant key exchange to wallet and agent workflows. (x.com) Post-quantum cryptography is a set of lock designs meant to survive future quantum computers, which could break today’s public-key systems such as elliptic-curve cryptography. Solana relies on Ed25519 signatures today, and Helius wrote in December 2025 that a full protocol shift would require broad changes across wallets, validators, and transaction formats. (nist.gov) (helius.dev) The specific algorithm in BridgeBaseAI’s announcement, Module-Lattice-Based Key-Encapsulation Mechanism 768, is a NIST-standardized way for two parties to agree on a shared secret over a public network. NIST published Federal Information Processing Standard 203 in August 2024 with three parameter sets—512, 768, and 1024—and says the method is intended for secure key establishment. (nist.gov) (nvlpubs.nist.gov) BridgeBaseAI’s beta says developers can generate Module-Lattice-Based Key-Encapsulation Mechanism 768 keypairs, use on-chain reputation features, and block transactions without holding a separate post-quantum token. The company also said the software development kit can be installed through npm and priced lifetime beta access at 19 United States dollar coin. (x.com) That pitch lands as Solana’s developer stack keeps expanding for automated software and trading bots. The Solana Agent Kit package on npm says it lets artificial intelligence agents perform more than 15 Solana actions, including swaps, lending, token launches, and staking, which increases the number of automated systems handling private keys and signing requests. (npmjs.com) Government cyber agencies have been telling operators to start planning now, even though large quantum machines capable of breaking current public-key cryptography do not yet exist. A joint fact sheet from the Cybersecurity and Infrastructure Security Agency, the National Security Agency, and NIST in August 2023 urged organizations to build a quantum-readiness roadmap and inventory where vulnerable cryptography is used. (cisa.gov) (nsa.gov) Solana projects are already testing that path in public. Helius published a December 5, 2025 research note on what Solana would need to change to become quantum ready, and Tekedia reported on April 6, 2026 that the Solana Foundation had partnered with Project Eleven to test quantum-resistant signatures on the network. (helius.dev) (tekedia.com) BridgeBaseAI appears to be taking a narrower route than a chain-wide cryptography overhaul. Its beta focuses on a gateway layer for wallets, developers, and artificial intelligence agents, which suggests an add-on security service rather than a replacement for Solana’s base signature scheme. (x.com) (bridgebaseai.github.io) For now, the company is selling access to a beta and a public demo, not announcing a Solana protocol change. The immediate test is whether developers building agent-driven apps decide that a 19 United States dollar coin gateway is worth adding before the rest of the stack moves. (x.com)
