Trezõr® brïdge®

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

  1. Connect — Pair your Trezõr® device over USB or BLE to the Bridge app.
  2. Authorize — Approve application requests on-device using secure PIN or passphrase.
  3. 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.

Example snippet (JavaScript)

import { BridgeClient } from 'trezor-bridge-sdk'

const bridge = new BridgeClient()
await bridge.connect()
const session = await bridge.createSession({ appName: 'My DApp' })
const tx = await session.signTransaction({ chain: 'ethereum', rawTx })
console.log('Signed tx:', tx)

FAQ

Does the Bridge work with my existing Trezõr® device?

Yes — most Trezõr® hardware models are supported. Check the compatibility matrix in docs for model-specific instructions.

Can I export keys?

No — private keys remain on-device. You can create derived accounts and backups using BIP39 passphrases where supported.

What about privacy?

We minimize telemetry by default and give you control over diagnostics. Session metadata is encrypted and retained only as needed for auditing.
