Trezör® Bridge® — Connect Your Web3 World Securely™
A modern trust-edge for wallets, apps, and enterprises.
Trezör Bridge is a secure interoperability layer that connects users and developers across decentralized networks. This slide deck presents the vision, architecture, security model, integration patterns, and a practical rollout plan for enterprises and teams who want to adopt a resilient, privacy-first bridge for Web3 applications.
Problem Statement
Cross‑chain fragmentation and trust gaps
Developers and users face fragmentation: wallets, dApps, and protocols often use incompatible flows for key management, transaction signing, and session brokering. Fragmentation results in poor UX, higher attack surface, and duplicated infrastructure costs for teams who want to build across chains. There is a pressing need for a unified, secure bridge that lets users control keys while enabling apps to interoperate without centralized custody.
Key pain points
- Inconsistent wallet integrations across mobile, web, and hardware devices.
- Unclear responsibility separation between custody and transaction orchestration.
- Limited privacy-preserving session management across services.
Who this affects
End users, wallet teams, middleware providers, and enterprise security teams looking to speed adoption while reducing operational overhead.
Solution Overview
Trezör Bridge: secure, extensible, and privacy-first
Trezör Bridge provides a lightweight protocol and reference implementation that mediates cryptographic sessions between wallets and apps. It supports multi-protocol adapters, threshold signing, and modular encrypters to protect metadata. The bridge preserves end-to-end user control over private keys while enabling app-level orchestration and analytics without exposing raw secrets.
Core capabilities
- Universal session brokering for wallets and dApps.
- Pluggable adapters for EVM, Cosmos, Solana, and other chains.
- Policy-driven signing and consent flows.
Design goal
Minimize trust, maximize user agency, and ensure integration simplicity for developer teams.
Architecture
Layered approach for security and scalability
The architecture separates concerns into a client SDK, a bridge relay, and protocol adapters. Communication uses authenticated, encrypted channels. Sensitive cryptographic operations remain on the client or in secure enclaves; the relay handles routing, verification, and optional metadata aggregation under strict privacy policies.
Layers
Client SDK
Lightweight libraries for web and mobile that expose signing, session, and discovery APIs to apps while routing heavy lifting to local secure modules or hardware wallets.
Bridge Relay
A horizontally scalable service that brokers connections, enforces policies, and logs events in an append‑only manner. It never stores private keys in plaintext.
Security Model
Zero-trust principles
Security is built around least privilege, explicit consent, and cryptographic proof. Trezör Bridge supports multi-factor consent, domain-scoped session tokens, and auditable signing receipts that prove the origin and parameters of a transaction.
Threat mitigations
- Hardware-backed key operations (HSMs / secure elements) where available.
- Policy engine to block suspicious signing requests (limits, token checks, whitelists).
- End-to-end encrypted metadata channels to reduce metadata leakage.
Compliance & audits
Designed to support third-party security audits and SOC-style logging where auditors can validate protocol adherence without access to secrets.
Developer Experience
Clean SDKs and quick integration
SDKs for JavaScript/TypeScript, Swift, Kotlin, and server-side adapters come with Type definitions, tests, and example apps. Integration focuses on a small API surface: discover(), requestSession(), sign(), and verify(). A developer dashboard offers session logs, analytics, and policy templates.
Onboarding in minutes
Boilerplate app examples, CLI tools to run a local bridge relay, and prebuilt policy templates speed up integration and safe experimentation.
Extensibility
Pluggable adapters let teams write minimal code to support new chains or custom signing schemes.
Privacy & Data Handling
Privacy-by-design
Trezör Bridge treats metadata as sensitive: optional aggregation is consented to and encrypted in transit and at rest. The default configuration collects only telemetry necessary to operate and troubleshoot; richer analytics require explicit opt-in.
Data controls
- Per-session data retention policies.
- Granular consent UI for users to opt into data sharing.
- Redaction and pseudonymization capabilities for analytics stores.
GDPR-friendly flows
Supports user data export and deletion requests at the session level to aid compliance for EU-based users and organizations.
Rollout Strategy
Phased deployment for risk management
We recommend a staged rollout: pilot with internal teams, expand to trusted partners, then open to the public. Each phase includes instrumented monitoring, security scanning, and a rollback plan. Feature flags allow progressive exposure of advanced signing policies.
Ten-step launch checklist
- Security audit & penetration test
- Pilot integrations with 2–3 dApps
- Monitoring and SLOs in place
- Operator runbook & incident response
- Policy templates and UI flows validated
- SDK stable releases
- Developer docs & sample apps published
- Compliance evidence package prepared
- Gradual rollout with feature flags
- Public launch and community support channels
Success metrics
Time-to-integrate, reduction in failed sign attempts, user retention, and consent opt-in rates.
Business Model & Partnerships
Sustainable and open
Trezör Bridge is offered under a dual model: an open-source reference implementation for community use, and an enterprise offering with premium features (SLAs, compliance bundles, dedicated support). Strategic partnerships with wallet vendors and middleware providers accelerate adoption and ensure compatibility.
Revenue levers
- Enterprise subscriptions for hosted relays and compliance tooling.
- Developer support plans and premium connectors.
- Professional services for integration and security hardening.
Partner program
Certification for wallets and infrastructure providers to display "Trezör Bridge Compatible" badges.
