About TZUR Wallet
Our Story
TZUR (צור) means “rock” or “flint” in Hebrew: something primitive, durable, and fundamental. We built TZUR because we believe Bitcoin self-custody should not require speaking English. Six billion people worldwide don’t speak English as their first language. Most Bitcoin wallets force users to write down their recovery seed phrase in English, a 12-word sequence that controls access to their funds. If you don’t understand the words, you can’t verify them. If you can’t verify them, you can’t trust them. TZUR is the first Bitcoin wallet that can generate and restore the BIP-39 recovery phrase in the user’s native language. Thirty-one languages are supported.
Our Mission
TZUR exists to make Bitcoin accessible to the non-English-speaking world. Not through simplified interfaces or custodial shortcuts, but through real self-custody with native language support. Understanding your seed phrase in your own language is not a convenience. It is a security requirement.
The Company
TZUR Wallet is developed and operated by BlockSight OÜ, a company registered in Estonia (registry code 17474529, verifiable in the Estonian e-Business Register). BlockSight builds tools for understanding and interacting with the Bitcoin network. Our flagship products are BlockSight.Live, a real-time Bitcoin blockchain explorer, and TZUR Wallet.
The Team
The BlockSight Ecosystem
TZUR is part of the BlockSight.Live ecosystem. BlockSight.Live is a real-time Bitcoin blockchain explorer featuring live block visualization, network dashboards, a congestion gauge, and Monica Metrics: five original Bitcoin network indicators. A Bitcoin wallet should not only move bitcoin but help users understand the network.
In the News
TZUR's native-language seed phrases and the multilingual BIP-39 proposal were covered by journalist Christine Kim in her newsletter BTC Before Light (Issue 44, June 2026).

Contributing to Bitcoin
The multilingual mnemonic work behind TZUR was submitted to the Bitcoin Improvement Proposal repository as a formal BIP draft (bitcoin/bips pull request #2200), and all thirty-one wordlists are published as open source. We build on Bitcoin's open standards, and we give back to them.
Bitcoin Standards
BIP-39 · BIP-32 · BIP-84
Native SegWit · Taproot Send · Replace-By-Fee
Zece din cele treizeci și una de liste de cuvinte BIP-39 acceptate sunt identice octet cu octet cu lista canonică Trezor. Toate treizeci și una sunt open source sub licența MIT. Standardul de bază este BIP-39 (Bitcoin Improvement Proposal 39).

Design Philosophy
TZUR is a focused tool, not a financial app. Bitcoin only. No altcoins, no tokens, no DeFi. One-time purchase, no subscriptions, no recurring fees. Available for Windows and iPhone today, coming soon to Google Play, with a separate TZUR for Agents wallet for AI agents. Every design decision follows one rule: if security and convenience conflict, security wins.
