Ripple and cryptocurrency company Project Eleven are developing a prototype quantum-proof custody wallet that is undergoing active testing with validators on the XRP Ledger (XRPL) blockchain.
According to an announcement made by the Project Eleven team on May 19 of this year, this work includes implementing post-quantum hybrid signatures, performance testing on Devnet, and a designed custody architecture. Resist quantum computing attacks.
For now, the information does not specify how many validators are testing the prototype or what percentage of the XRPL network is participating in the testing, but the partnership is part of Phase 2 of the roadmap published by Ayo Akinyele, RippleX’s senior director of engineering, on April 20th.
The goal of this phase, scheduled for early 2026, is to fully evaluate the performance, storage, and storage implications of post-quantum cryptography, according to Ripple. Check network bandwidth and identify required architectural adjustments.
The initiative was prompted by a recent study by Google Quantum AI reported by CriptoNoticias, according to published documents. It has been shown that the cryptography used in most cryptocurrency networks today can be compromised by sufficiently advanced quantum computers, including the algorithms that protect wallets, sign transactions, and secure digital assets.
As a company specializing in post-quantum cryptography, Project Eleven is joining the project to build and implement the technical solutions needed for Ripple to complete the transition phase. signature Build a proof-of-concept implementation of post-quantum hybrid signaturesThis includes validator-level testing, Devnet benchmark testing, and a post-quantum custody wallet prototype.
XRP Ledger has structural advantages compared to other networks
Ripple believes that XRPL is Has native functionality to ease migration– Account-level key rotation allows users to replace weak keys without changing their accounts, and seed-based key generation allows new cryptographic material to be derived deterministically. The company says neither feature exists natively on networks like Ethereum.
Project 11 warns that the risks are operational as well as technical, as they impact each XRP holder and each application built on the network.
The company is also considering an emergency scenario called “Q-Day.” Commit before completing the migrationXRPL activates a contingency plan that prevents the use of traditional signatures and allows users to transfer funds through zero-knowledge proofs.
The roadmap also envisions a complete transition to post-quantum signatures as a formal modification of the XRPL protocol, with a goal of 2028. By then, networks will need to process signatures that are resistant to quantum attacks without compromising deterministic payment speeds, according to Project Eleven.
So far, only 0.03% of XRP supply is exposed to quantum attacks compared to 35% for Bitcoin, positioning XRPL As a cutting-edge blockchain for post-quantum support.
This is a series of initiatives that many companies and networks are moving forward with. This means that even if the quantum threat is not imminent, the scenario is Harvest now, decrypt later — Attackers are currently storing encrypted data for decryption on future quantum computers — Currently Bringing true urgency to the industry.
