Platform modules
Everything an operator needs, audited end to end.
Each module reads live on-chain data and is scoped to your account by row-level security — nothing is shared between tenants.
Live chain data
Confirmed and pending balances, fees and history streamed from redundant public Bitcoin nodes.
Licensed sessions
Broadcast sessions bound to your key, with enforced daily quotas and per-session volume caps.
Analytics
Volume curves, success rates and per-session address breakdowns computed from your own ledger.
Verified treasury
Withdrawals require an on-chain fee deposit that is verified against the blockchain before release.
Ten languages
Full interface localisation including right-to-left layouts, switchable from your account settings.
Release 4.2.1
What's new in Core 4.2.1
Faster propagation, deeper stealth and a full multi-asset treasury — shipped straight to the browser, with no installer and no footprint on your machine.
Turbo broadcast engine
Rebuilt session pipeline pushes flash transactions to the relay set in under 80 seconds, with live per-step telemetry.
Stealth relay routing
Automatic node rotation and randomised propagation delays keep every broadcast pattern indistinguishable from organic traffic.
Device-bound licensing
Keys bind to a single hardware fingerprint, with instant revocation and quota enforcement from the operator console.
Multi-asset treasury
Convert between BTC and USDT, transfer to any platform account by email, and withdraw to your own receiving address.
Redundant node mesh
Mempool, height and fee data are aggregated from multiple independent public nodes with automatic failover.
On-chain fee verification
Every payout fee deposit is matched against the blockchain — wrong hashes and short payments are refused automatically.
Session ledger
Each broadcast writes an immutable ledger entry, exportable and reconcilable down to the satoshi.
Ten-language console
Complete interface localisation, including right-to-left layouts, switchable at any time from settings.

Operating sequence
Four steps from sign-up to settlement.

Pay in BTC, receive a key bound to your account and device, with explicit volume and session limits.
- 03

Recovery phrase or xpub verified locally; derived public addresses are connected for monitoring.
- 04

Non-custodial by design
Seed phrases and extended keys never leave the browser. Zuru never stores private keys or customer funds.
Licensed access control
Every key binds to one account and one device fingerprint, enforces quotas and expires automatically.
Server-verified payouts
Fee deposits are validated against the Bitcoin network before a withdrawal ever moves to server validation.
