Protocol-native payment required. Not a redirect gauntlet. Not a bolted-on checkout tab.
the on-chain browser
vapurr

Browse, settle, and prove — without bolting the economy onto the side of Chrome.
Product
One chrome for the chain.
Wallet keys stay on device. Mail is encrypted and identity-aware. Payments speak the status codes the web already defined. Identity proves what matters — and nothing else.
Native wallet
Keys never leave the machine.
Browse and settle from the same surface. No extension bolted on. No third-party popup stealing focus mid-transaction.

zmail
Encrypted mail, inside the browser.
Identity-aware messaging where you already live on the open web — not another app asking you to leave the tab.

zer0ID
Prove what matters.
Reveal nothing else.
Privacy-preserving credentials built into the browse path. Durable state is an opaque nullifier — not a passport scan sitting in someone else’s bucket.
- Nullifier-onlySybil-resistant uniqueness without dumping raw KYC into every site.
- On-device proofWitnesses stay local. Verifiers see math, not your documents.
- Same chromeIdentity lives next to the tab — not behind a redirect gauntlet.
Payments
Settlement in the chrome.
When a resource asks to be paid for, vapurr settles natively — HTTP 402 via x402 and KetPay, in the same surface you browse from.
Value exchange that belongs in the browser — calm, local, and honest about what is being paid for.
Windows
Get the desk build.
Direct channel binary — no installer wrapper on this host. SmartScreen may warn on unsigned builds; that is expected for this release.
