Overview
What is the Developer Portal?
The Trezor Suite® Developer Portal consolidates resources, docs, and examples to help you build secure integrations with Trezor hardware and software. Whether you're creating a desktop wallet, merchant integration, or an experimental dApp, the portal shows recommended flows, API usage, and verification practices. This presentation distills the essentials and links to the authoritative resources.
Why build with Trezor?
Trezor devices focus on separating private key operations from internet-connected systems. Developers benefit from open-source tooling, audited firmware, and well-documented APIs for safely requesting public keys, signing transactions, and authenticating users. Integrations prioritize user consent and cryptographic proof so end-users keep custody of their keys.
Setup & Getting Started
Step 1 — Install Trezor Suite
Download and install Trezor Suite for desktop or use the web app to start. The Suite is the recommended entry point for everyday management and updates. Confirm OS requirements, verify the download, and follow the official on‑boarding flow to create or recover a wallet.
Step 2 — Connect your device
Use the supported connection method (USB or Bluetooth, depending on model) and allow the device to pair. Newer models may include wireless pairing instructions. Always verify the device fingerprint on the device screen when prompted during a sensitive operation.
Developer tools to install
- Trezor Suite (desktop or web)
- Node.js and package manager (npm/yarn) for building JS integrations
- Repository clones of trezor-suite and trezor-firmware if you plan to contribute
- Optional: Trezor Connect library for web-based integrations
Trezor Connect — Quick Reference
What is Trezor Connect?
Trezor Connect is a JavaScript API that exposes safe, user-mediated operations such as retrieving public keys and signing transactions. The library always routes critical prompts to the physical device so users explicitly confirm actions, and the host app receives only signed responses.
Typical call flow
- Host app requests an operation via Trezor Connect.
- Trezor Connect opens the bridge or native Suite transport to the device.
- The user reviews the transaction details on the device and confirms.
- The device signs the payload and returns the signature to the host app.
Best practices
Keep user prompts minimal but unambiguous. Never assume message contents — always display the exact amounts, recipient addresses, and metadata for user confirmation. Validate returned signatures server-side when needed, and log only non-sensitive metadata.
Security & Verification
Open-source and reproducible builds
Trezor emphasizes reproducible software and public source repositories. For high‑value integrations, review firmware and Suite source code, and follow the official verification steps to ensure binaries match the source.
Keeping users safe
Defend against supply-chain and phishing risks by guiding users to official download pages, educating them about verifying firmware, and showing the device's verification prompt during sensitive operations. Avoid collecting or storing recovery seeds—encourage on-device-only storage.
Authoritative links (10 official resources)
Below are curated official resources you should bookmark while developing with Trezor.
Wrapping up
This one‑page presentation gives you structured, developer-focused guidance and 10 official links for further exploration. Use the headings H1–H5 above as a template for slides or a documentation outline. For production integrations, always follow the official docs, test on sandbox devices, and never bypass on‑device confirmations.
Happy building — and remember: custody starts with clear user consent and auditable cryptography.
