XRP Ledger sketches quantum-resistant accounts with no added fees

The XRP Ledger Foundation has laid out a way for XRPL accounts to withstand quantum computers. The mechanism is simple: an owner adds a quantum-resistant key to an account, then switches off the original key.

That's the whole idea. Old key out, new key in.

CoinDesk reports that users won't pay extra fees for the upgrade. The design sits inside a broader roadmap that has the network on track for a full transition by 2028.

What's actually changing

This works at the account level. Nobody gets pushed onto a new system all at once. Holders add a new kind of key to the account they already have. The step that matters is disabling the legacy key, because a key that's turned off can't sign anything, which shuts the door on a future quantum attacker.

The summary we have doesn't say which cryptographic schemes the ledger will use, or what the exact technical steps look like. Those details matter a lot, and I'll be watching for them.

Why it matters

Quantum risk is a slow-burn threat. Still, every major chain will have to answer it eventually. XRP has put a date on its answer: 2028. That's a concrete target, and plenty of networks haven't offered one.

For holders, the practical point is cost. If the upgrade really is free, the main barrier to acting is attention. But a design isn't a shipped feature. The real test is whether wallets, exchanges and custodians support the new keys in time, and how many people actually rotate theirs. A safer option nobody uses protects nobody.
