~/wallet $ ./a480 --any-device

Crypto that runs on anything with a screen.

A480 is a featherweight crypto wallet built to run on the slowest, oldest hardware you own — a 25-year-old PC, a budget phone, a school computer, a cheap tablet. No bloat, no heavy frameworks, just a few hundred kilobytes. Crypto should be for everyone, not only people with brand-new devices.

how_it_works

Tiny on purpose. Fast everywhere.

A480 throws out everything heavy. The whole wallet is a handful of files that load instantly, even on hardware most apps gave up on years ago.

step_01~2s

Install & open

Under half a megabyte. It opens in seconds on a single-core CPU — no waiting, no spinner.

step_02local

Keys made on-device

Your seed phrase is generated and stored locally. Nothing heavy runs in the background.

step_0356k ok

Send & receive

Lightweight calls sip data, so it keeps working on slow or flaky connections.

features --list

Built for the machines everyone forgot.

feat_01[core]

Featherweight

The entire wallet is a few hundred kilobytes — no React, no Electron, no gigabytes of dependencies.

feat_02[core]

Runs on ancient specs

16 MB of RAM, a single slow core and a 640×480 screen are enough. If it powers on, it runs A480.

feat_03[net]

Slow-connection ready

Minimal data per action means it stays usable on 2G, public Wi-Fi or a literal dial-up line.

feat_04[sec]

Non-custodial

Your keys and seed phrase live only on your device. We never hold, see or control your funds.

feat_05[ui]

High-contrast, keyboard-first

A clear, readable interface that works without a mouse, a touchpad or any fancy animation.

feat_06[chain]

Multi-chain basics

Bitcoin and the major coins at launch, kept deliberately simple and light, with more added in beta.

If it ran in 1999, it runs A480.

Got an old machine? We need it.

A480 is an early prototype built by an independent developer in Tallinn, Estonia. The best testers are people with genuinely old, slow or unusual hardware — the stuff nobody else bothers to support.

Questions & answers

Q1 Does A480 really run on a 25-year-old computer?
That's the whole point. A480 is built without heavy frameworks, so the install is under 500 KB and it runs on roughly 16 MB of RAM, a single slow CPU and a 640×480 screen. If your machine boots a basic browser or OS from the late 1990s onward, it should run A480.
Q2 How is it so small and fast?
By cutting everything non-essential — no bloated UI libraries, no background processes, no auto-playing animations. It's plain, lean code that loads instantly and sips data, which is also why it survives slow connections.
Q3 Is a lightweight wallet still secure?
Yes. A480 is fully non-custodial: your private keys and seed phrase are generated and stored only on your device and never transmitted. Being small means there is less code to go wrong — but this is an experimental prototype, so use small amounts.
Q4 Which devices and coins are supported?
Old PCs, budget phones, single-board computers, school/library machines and smart-TV browsers are all targets. It supports Bitcoin and the major coins at launch, with more added during the beta. Test only with small amounts during the prototype.
Q5 Do I need a fast internet connection?
No. A480 is designed to be usable on 2G, congested public Wi-Fi or even dial-up. It transfers the minimum data needed for each action and degrades gracefully when the connection is poor.
Q6 Who is behind A480 Wallet?
A480 Wallet is built and operated by Svetlana Aleksandrova, an independent software developer based in Tallinn, Estonia. Reach her at [email protected] or on Telegram at @a480_wallet.
