A full audit of the XRP Ledger’s validators, custody systems, wallets, and networking layers is now underway. It’s being led by quantum security firm Project Eleven in partnership with Ripple. This review is part of a larger effort to prepare the XRP Ledger ecosystem for a future where quantum computers could break the cryptographic systems that blockchains currently depend on.

Project Eleven’s Work Goes Beyond Research
Project Eleven described this collaboration as one of the first major industry efforts to move post-quantum blockchain security from theory into real-world use. The firm said the work will produce actual code, real-world performance testing, and a clear plan for 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 discussions about quantum risk in the blockchain space have stayed at the research level. He noted that Ripple 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. This allows businesses, projects, and users to seamlessly switch to quantum-resistant signatures while keeping the exact same r-addresses their customers… https://t.co/ydDVSrdFkL pic.twitter.com/cXij19CNq1 — XRP Ledger Foundation (@XRPLF) May 19, 2026
The US government has set a 2035 deadline for federal systems to move away from encryption standards that are vulnerable to quantum attacks. Google and Cloudflare have both targeted 2029 for their own transitions to quantum-safe systems.
XRP Ledger’s Built-In Advantages
The XRP Ledger Foundation said the network isn’t 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 key detail the foundation highlighted: users and businesses will be able to switch to quantum-resistant signatures without changing their existing XRP wallet addresses. These addresses, known as r-addresses, are already familiar to customers. Keeping them intact during a migration removes a major 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 firm said that the cryptography protecting major blockchains—including Bitcoin, Ethereum, XRP, and Solana—could eventually be broken by advanced enough quantum computers.

Frequently Asked Questions
Here is a list of FAQs about Ripple and Project Eleven teaming up to prepare the XRP Ledger for the quantum era
BeginnerLevel Questions
Q What is Project Eleven
A Project Eleven is a team of experts focused on making the XRP Ledger secure against future quantum computers They are working on a plan to update the ledgers cryptography so it cant be broken by superpowerful quantum machines
Q Why does the XRP Ledger need to be ready for quantum computers
A Current computers cant easily break XRPs security But future quantum computers could crack the math that protects your wallet and transactions Preparing now ensures your funds stay safe when that technology arrives
Q What exactly is Ripples role in this
A Ripple is funding and supporting Project Elevens research They are providing resources and expertise to help develop and test the new quantumresistant security features for the XRP Ledger
Q Will this change affect my XRP tokens or my wallet
A Eventually yes You will likely need to upgrade your wallet or move your XRP to a new quantumsafe address The team is designing the upgrade to be as smooth as possible so you wont lose your tokens
Q When will this quantum upgrade happen
A There is no exact date yet The team is still researching and testing It will likely take years to fully deploy but they want to have a plan ready before quantum computers become a real threat
Advanced Questions
Q What specific cryptographic algorithms are they replacing on the XRP Ledger
A They are targeting the current signing algorithm ECDSA and the hashing algorithm SHA256 These are the core math functions that protect your private keys and transaction signatures They plan to replace them with postquantum algorithms like Falcon or Dilithium
Q How will the upgrade actually work without breaking the existing ledger
