Overview
Purpose
This presentation targets developers, security engineers, and power users who need a compact but technical reference to Trezor Suite. It covers architecture, advanced settings, integration patterns, and best practices to operate hardware wallets in high-assurance environments.
Architecture & Trust Model
Core components
Trezor Suite is a host application that communicates with a Trezor hardware device over USB or WebUSB. The Suite isolates key management in the device's secure element (or firmware-managed enclave). Critical assumptions: supply-chain integrity of the device, firmware authenticity, and host OS integrity.
Threats & mitigations
Mitigations include firmware verification, passphrase-protected hidden wallets (plausible deniability), and use of a dedicated, hardened host for signing operations.
Advanced Configuration
Device provisioning
For enterprise-grade setups, provision devices using a deterministic process: create seed on-device, record device fingerprints, and store a hashed device manifest in a secure inventory. Avoid exporting seeds; use watch-only descriptors for monitoring.
Passphrase & hidden wallets
Use passphrases as an additional derivation path. Treat passphrases as high-entropy secrets — store them in hardware-backed secrets managers when automating headless signing flows.
Integrations & Automation
Headless signing
Trezor devices can be integrated into CI/CD or cold-signing workflows via the Trezor Bridge and command-line tools. Use ephemeral, network-isolated hosts and sign only pre-validated transactions. Record signed transaction receipts with signed metadata for non-repudiation.
Developer tips
Pin the Suite and bridge versions in automation to avoid breaking changes; use reproducible Docker images to encapsulate signer stack.
Operational Best Practices
Audits & reproducibility
Keep firmware, Suite and tooling versions recorded. Automate periodic verification of firmware signatures and device attestation where supported. Maintain an audit trail linking device fingerprint, firmware hash, and signing events.
Incident response
Prepare cold-restore plans and ensure multisig recovery policies are tested regularly. Rotate passphrases and review inventory when devices are lost or decommissioned.
Conclusion
Key takeaways
Trezor Suite is suitable for advanced users when combined with rigorous provisioning, pinned tooling, secure passphrase management, and documented signing workflows. For enterprise usage, pair hardware wallets with multisig and dedicated signing hosts.
