Secure Crypto Connectivity for Wallets, Exchanges, and DeFi

A resilient, low-latency bridge and connectivity layer that brings institutional-grade security and developer-friendly integrations to blockchain applications.

About Trézór Bridge®™

Trézór Bridge®™ is designed to solve the hardest connectivity problems in blockchain infrastructure: secure cross-environment message delivery, end-to-end encryption, identity-preserving key routing, and predictable latency. Whether you are a wallet provider syncing accounts, a DeFi protocol relaying price oracles, or an exchange managing hot/cold flows, Trézór Bridge®™ delivers consistency and security without sacrificing developer ergonomics.

End‑to‑end encryption
All transport is encrypted with modern ciphers. Private keys are never exposed during transit.
High availability
Regional clusters, active‑active replication, and failover routing for zero single-point-of-failure.
Native web3 integrations
Prebuilt connectors for Ethereum, EVM-compatible chains, Solana, Bitcoin, and cross-chain messaging layers.

Core capabilities

  • TLS + application-level encryption with forward secrecy
  • Deterministic message ordering and replay protection
  • SDKs for JavaScript, Rust, Go, and Python
  • Audit-ready logging and optional privacy-preserving telemetry

Security model

Security is built into every layer of Trézór Bridge®™. Our platform follows a defense-in-depth approach: platform boundaries are minimized, privileged operations require multi-party authorization, and cryptographic primitives meet current industry recommendations.

Key handling

Private keys and signing material are always stored in optional customer-managed HSMs or in isolated secure enclaves. On-host secrets never leave protected memory. When using our managed offering, key material is stored in FIPS 140-2 validated HSMs and logged with strict access controls and immutable audit trails.

Network guarantees

Our network layer provides authenticated endpoints, TLS 1.3 by default, and application-layer signatures to detect tampering. Replay windows, nonce-based protections, and deterministic monotonic counters protect against duplication and message reordering attacks.

Compliance & audits

Trézór Bridge®™ undergoes regular third-party security assessments, open-source protocol reviews, and supports compliance frameworks typically required by institutions integrating digital-asset infrastructure.

Architecture at a glance

Trézór Bridge®™ is a horizontally scalable service that separates control-plane and data-plane concerns. The control plane handles authorization, routing policies, and observability. The data plane focuses on encrypted data forwarding and deterministic delivery. Edge gateways connect to regional clusters through mutually authenticated tunnels and negotiate session-level keys for end-to-end encryption.

Components

  1. Edge gateway — lightweight connector deployed in your environment or in our managed edge for fast, localized routing.
  2. Regional cluster — redundant brokers that coordinate message delivery and persistence.
  3. Control API — policy orchestration, access controls, and integration endpoints for developer tooling.
  4. SDKs & connectors — client libraries that simplify session lifecycle, retries, and schema validation.

This separation ensures predictable performance while enabling strict access controls for administrative operations.

Use cases

Trézór Bridge®™ supports a wide variety of real-world deployments:

  • Wallet providers — sync accounts and broadcast signed transactions while keeping keys offline.
  • Exchanges — orchestrate hot-to-cold workflows and securely stream chain data for reconciliation.
  • DeFi protocols — relay oracle feeds and cross-chain events with integrity guarantees.
  • Custodians — enforce multi‑party controls and auditable flows between custodial systems and blockchains.

Performance

Built to minimize tail latency: clients observe deterministic delivery with configurable consistency (from at-most-once to exactly-once semantics) and throughput scaling to millions of messages per minute across clustered deployments.

Developer experience

We ship clear, concise SDKs and reference applications so your engineers can integrate quickly. Emphasis is placed on ergonomics, type-safe schemas, and secure defaults. The SDK handles exponential backoff, idempotency keys, and helper middleware for signing and schema validation.

Example: Secure publish (pseudo)

await bridge.publish('oracle-price:ETH-USD', {
  price: '3450.12',
  timestamp: Date.now(),
  signature: await signer.sign(payload)
});

Comprehensive docs, sandbox environments, and dedicated technical support are available to enterprise customers.

Frequently asked questions

Is Trézór Bridge®™ custodial?

No — Trézór Bridge®™ is a connectivity layer. Custodial decisions, key custody models, and signing policies remain with the integrator. We provide tooling for managed HSMs and bring-your-own-key models.

How do you handle cross‑chain messaging?

We rely on secure relayers and connectors that interface with native chain clients and standardized cross-chain messaging protocols. Each connector enforces message validation, proofs where available, and optional multi-signature attestation.

Can I run Trézór Bridge®™ on-prem?

Yes — we offer on-prem and hybrid deployment models so security-sensitive teams can host edge components behind firewalls while leveraging managed regional clusters for scale.
