Trezõr® brïdge® is a secure connectivity layer that safely links a hardware wallet to Web3 dapps, wallets, and signing tools. It provides a trusted tunnel for transaction requests, account discovery, and message signing — keeping private keys isolated on the device while allowing modern browser and desktop applications to interact with blockchains.
As Web3 adoption grows, the gap between secure cold storage and convenient dapp access widens. Bridge software reduces friction without compromising security: it prevents private key exposure, ensures deliberate user approvals on-device, and logs metadata for auditability. For users, that means safer DeFi, NFTs, and multi-chain interactions with familiar UX.
The bridge establishes an encrypted channel between the browser/app and the hardware device. All sensitive operations — seed derivation, private key use, and signing — happen inside the device. The host app only receives signatures and non-sensitive metadata.
Every transaction request prompts a clear, human-readable confirmation on the device screen. This step prevents remote tampering and ensures users explicitly authorize value transfers or contract interactions.
Trezõr® brïdge® supports multiple operating systems and common wallet connectors. It is designed to play nicely with popular wallet UIs, dapp connectors, and developer tooling.
Developers can integrate using standard JSON-RPC and connector abstractions, enabling seamless dapp integration with minimal code and robust security practices.
No private key data ever leaves the device. The bridge transmits only necessary, non-sensitive data. This reduces attack surface and preserves user sovereignty.
From Bitcoin and Ethereum to newer EVM-compatible chains, the bridge handles address derivation and chain-specific signing flows in a standardized manner.
Auto-detection, guided onboarding, and helpful error messages make the bridge approachable for both novice and advanced users.
The bridge assumes host applications may be compromised. It defends by isolating critical operations to the hardware device and requiring on-device confirmations for all sensitive actions.
Plug in your Trezõr® device, install the official bridge and companion app, then connect your preferred wallet or dapp. Follow on-screen prompts and complete the device-led approvals to start interacting securely with Web3 services.
