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.
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.
Install & open
Under half a megabyte. It opens in seconds on a single-core CPU — no waiting, no spinner.
Keys made on-device
Your seed phrase is generated and stored locally. Nothing heavy runs in the background.
Send & receive
Lightweight calls sip data, so it keeps working on slow or flaky connections.
Built for the machines everyone forgot.
Featherweight
The entire wallet is a few hundred kilobytes — no React, no Electron, no gigabytes of dependencies.
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.
Slow-connection ready
Minimal data per action means it stays usable on 2G, public Wi-Fi or a literal dial-up line.
Non-custodial
Your keys and seed phrase live only on your device. We never hold, see or control your funds.
High-contrast, keyboard-first
A clear, readable interface that works without a mouse, a touchpad or any fancy animation.
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.
Here's the minimum spec. Almost anything you can still switch on today clears it with room to spare.
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.
Beta testers

Retro tinkerers
- Test on vintage PCs, SBCs and odd browsers.
- Push the minimum-spec limits and break things.

Questions & answers
Q1 Does A480 really run on a 25-year-old computer?
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.
