SaveWallet 2.4.0 introduces a quantum-safe (post-quantum) wallet you can create and use right now on the TRON Nile testnet — signed with Falcon-512, the post-quantum scheme standardized for TRON as TIP-899. It is, as far as we know, one of the first TRON wallets to put a working quantum-resistant wallet in your hands — and it is still the same low-fee, non-custodial wallet you already use for USDT and TRX.
Here is what shipped, what it means, and how to try it.
Why a "quantum wallet" matters
Almost every crypto wallet in existence — Bitcoin, Ethereum, and standard TRON wallets included — signs transactions with elliptic-curve cryptography (secp256k1). It has protected funds for over a decade. But it has one long-term weakness: a sufficiently powerful quantum computer could one day derive a private key from its public key and forge signatures.
That day is not here yet. But the cryptography world is already migrating to post-quantum algorithms, and the wallets that prepare early are the ones whose users are never caught out. A quantum-safe wallet — also called a post-quantum or quantum-resistant wallet — signs with an algorithm a quantum computer cannot break.
SaveWallet uses Falcon-512, the post-quantum signature scheme standardized for TRON as TIP-899.
What's new in SaveWallet 2.4.0
On the TRON Nile testnet, version 2.4.0 lets you:
- Create a quantum-safe wallet from scratch, secured by Falcon-512 (TIP-899).
- Upgrade an existing wallet to quantum-safe with a guided, step-by-step wizard that explains every consequence before you commit — including the fact that a quantum key has no seed phrase, only its key strings, and that the upgrade is irreversible.
- Restore a quantum wallet from its private key alone — the one string you are told to keep is a complete backup.
- Sign into dApps from a quantum-safe wallet. A new off-chain message envelope (TPQ1) lets a post-quantum wallet complete Web3 logins and signing requests, so a quantum wallet is not a second-class citizen.
- Rent energy from a quantum-safe wallet, the same as any other, so your transfers stay cheap.
Everything above is live on Nile today.
This is a testnet preview — here's the honest part
Quantum-safe wallets in SaveWallet are a preview on the TRON Nile testnet. TRON must activate post-quantum signing (the TIP-899 / ALLOW_FN_DSA_512 feature) on mainnet before quantum wallets work there.
The good news: SaveWallet is written to follow the chain. The day mainnet turns post-quantum signing on, your quantum-safe wallet works — with no app update needed. Security-minded users get to learn the flow, test it end to end, and be ready first. We would rather tell you exactly where this stands than dress a testnet feature up as something it is not.
Quantum-ready shouldn't cost more — or slow you down
A wallet that chases one buzzword and forgets the basics is not worth switching to. SaveWallet is a genuinely great everyday TRON wallet first:
- Cheapest fees, automatically. Energy and bandwidth are optimized on every USDT (TRC20) and TRX transfer, with nothing to configure. You see the exact fee before you send.
- Fast. Opens and sends in seconds.
- Light. Runs smoothly even on older, low-memory phones, with a built-in Lite mode that saves data and memory automatically.
- Full-featured. Send, receive, stake, vote, swap via SunSwap, WalletConnect v2, a Web3 dApp browser, and full TRC20 / TRC10 token management.

Your keys, your coins
SaveWallet is 100% non-custodial: no sign-up, no email, no account, no tracking, no KYC. Your recovery phrase and private keys — quantum or classic — are encrypted and stored only on your device. Biometric unlock and a passcode lock guard every sensitive action, and every dApp request is shown in plain language before you sign.
How to try the quantum-safe preview
- Update to (or install) SaveWallet 2.4.0.
- Switch the network to Nile in settings.
- Create your first quantum-safe wallet — or run the Quantum-Safe upgrade wizard on a test wallet to see the full flow.
- Send a transfer, rent energy, or sign into a dApp from it — all with Falcon-512 signatures.
The takeaway
If you have been searching for a quantum wallet, a post-quantum crypto wallet, or a quantum-resistant TRON wallet, SaveWallet 2.4.0 is one you can actually use today — on Nile testnet, for free, with the lowest fees on TRON and a wallet light enough for any phone.
Update to SaveWallet 2.4.0, switch to Nile, and create your first quantum-safe wallet.
