Ripple And Project Eleven Join Forces To Make XRP Ledger Quantum-Ready

A full audit of the XRP Ledger’s validators, custody systems, wallets, and networking layers is now underway, led by quantum security firm Project Eleven in collaboration with Ripple.

The review is part of a broader push to prepare the XRP Ledger ecosystem for a future where quantum computers could threaten the cryptographic systems that blockchains currently rely on.

Project Eleven described the collaboration as one of the first major efforts in the industry to move post-quantum blockchain security out of the theoretical stage and into real-world deployment.

The firm said the work will produce actual code, real-world performance testing, and a roadmap toward production. Plans also include building hybrid signature systems that combine current cryptographic standards with quantum-resistant protections, along with a prototype quantum-secure custody wallet.

Alex Pruden, CEO of Project Eleven, said most conversations around quantum risk in the blockchain space have stayed at the research level. Ripple, he said, is treating it as a practical engineering problem.

The $XRP Ledger is built for the Quantum Era.

It runs on a native account based architecture with built in key rotation.

The US government has set a 2035 deadline for federal systems to move away from encryption standards considered vulnerable to quantum attacks. Google and Cloudflare have both targeted 2029 for their own transitions to quantum-safe systems.

The XRP Ledger Foundation said the network is not starting from scratch. According to the foundation, XRPL already supports key rotation and coordinated validator upgrades, features that give it structural advantages as the broader ecosystem moves toward quantum-resistant cryptography.

One detail the foundation highlighted: users and businesses will be able to switch to quantum-resistant signatures without changing their existing XRP wallet addresses.

Those addresses, known as r-addresses, are already recognized by customers. Keeping them intact during a migration removes a significant technical and operational hurdle.

J. Ayo Akinyele, head of engineering at RippleX, said the goal is to have XRPL production-ready well before quantum threats become a real danger.

According to Project Eleven, the Ripple partnership is its most comprehensive blockchain security engagement to date. The cryptography protecting major blockchains including Bitcoin, Ethereum, XRP, and Solana could eventually be broken by advanced enough quantum computers, the firm said.
