Connect Your Web3 World Securely™ — hardware-first identity & gateway for dApps
One bridge. Many chains. Total control.
Trezõr® brïdge® puts hardware-backed keys between you and the internet so you can sign transactions, authenticate with dApps, and manage identities without exposing secrets to the cloud.
Universal Wallet Connect
Connect to dozens of wallets and dApps across EVM, Cosmos, Solana and more.
Privacy by design
Private key never leaves your device — ever. Metadata minimized.
Developer friendly
Simple SDKs, REST & WebSocket APIs for fast integration.
How it works — in 3 steps
Connect — Pair your Trezõr® device over USB or BLE to the Bridge app.
Authorize — Approve application requests on-device using secure PIN or passphrase.
Sign — The Bridge signs transactions locally and returns only the signed payload to the app.
Quick setup (macOS / Windows / Linux)
1. Download & install the Trezõr® brïdge® app
2. Connect your Trezõr® hardware device via USB (or pair via Bluetooth)
3. Open the app and follow on-screen pairing instructions
4. Approve the dApp from your device when prompted
Security — hardware-first, audit-ready
Trezõr® brïdge® is designed around the principle that your private keys are the single most valuable asset. We keep them isolated inside the hardware secure element and only expose signed transactions.
Secure Element
Keys stored in certified secure hardware (SE) — tamper-resistant and non-exportable.
Attested Firmware
Device and Bridge mutual attestation prevent man-in-the-middle and rogue clients.
Session Controls
Revoke sessions, set transaction limits, and audit activity from the Bridge dashboard.
For enterprises
Bring your own key policies, HSM integration, SSO for admin access, and on-prem deployments for full compliance.
Developer notes
Design your dApp to ask for scoped requests, request minimal metadata, and present clear user prompts. The Bridge SDK abstracts transport and device negotiation so you can focus on product features.
