Inscribe. Host. Register — permanently on the BSV blockchain, 100% in your browser.
BSVKey is a serverless, client‑side tool for the Bitcoin SV chain. Your private key never leaves your browser tab and there is no backend — everything is built, signed, and broadcast locally.
🔑 App: bsvkey.com
- Inscribe — write text or files on‑chain via
OP_RETURN. - Host — publish full HTML pages on‑chain (CHOST); one wallet can host multiple named sites, each resolving to its latest version.
- Register names — claim human‑readable names in an on‑chain, first‑claim‑wins registry; visit any site at
bsvkey.com/#site=name. - Wallet — single‑key or HD recovery‑phrase wallets, balance & fiat value, history, sweep, and stuck‑transaction fixes.
- On‑chain feed — scan, read, and post messages the world is inscribing.
- 100% client‑side; keys are never transmitted or stored on a server.
- The bundled library is pinned with Subresource Integrity, and the app's code hash is inscribed on‑chain so anyone can verify the page they're running is authentic.
- Open and inspectable — download the source right from the app.
- name-index — optional, free indexer (GitHub Actions + Pages) that publishes a static
names.jsonsnapshot of the on‑chain name registry for instant lookups. BSVKey falls back to a trustless on‑chain scan if it's unavailable.
BSVKey is provided as is, without warranty. On‑chain writes are permanent and public, and you are solely responsible for your keys and funds. Nothing here is financial advice.
