Trézór Bridge — Secure Crypto Connectivity for enterprises and developers

Trézór Bridge delivers secure crypto connectivity across chains and custody layers while preserving privacy and operational simplicity. Built with modern cryptographic patterns, strong access controls, and clear audit trails, Trézór Bridge helps organisations move value with confidence.

What is Trézór Bridge?

Trézór Bridge is a connectivity layer that enables secure, auditable and efficient transfers between wallets, custody providers, and blockchains. It serves as a bridge without exposing private keys or reducing control.

  • Seamless integration via REST & WebSocket APIs
  • Adaptive routing for low-fee, high-availability paths
  • End-to-end encryption for messages and transaction payloads
  • Comprehensive logging and compliance features

Core principles

  • Least privilege: minimize access zones and use ephemeral credentials.
  • Non-custodial flow: keys never leave the owner’s secure environment.
  • Secure Crypto Connectivity: engineered for confidentiality, integrity, and availability.
  • Observability: telemetry, alerts, and audit-ready exports.

How it works (simple)

Trézór Bridge mediates transaction requests using encrypted channels. When a transfer is initiated, the bridge negotiates the best route, validates policies, and coordinates signatures without taking custody of funds.

Security stack

The security model combines hardware-backed key signing, multi-party computation (optional), and robust role-based access control. All communications are authenticated and encrypted using modern TLS and authenticated encryption schemes.

Benefits for businesses

Trézór Bridge reduces operational risk while increasing throughput and transparency. Teams gain a single integration point for transfers across multiple ledgers, enabling consistent policy enforcement and faster recovery procedures.

  • Reduce reconciliation time by centralising connectivity
  • Streamline KYC/AML compliance with detailed transaction metadata
  • Improve uptime using parallel routes and health-aware failover
  • Preserve user ownership of private keys and signing authority

Developer-friendly

Engineered for simple developer adoption: clear SDKs, interactive sandbox, and example integrations for common custody providers and wallets. The API focuses on predictable behavior, strong typing, and easy replayable requests for debugging.

// Example pseudo-request
POST /v1/bridges/transfer
{
  "from": "wallet:did:...",
  "to": "chain:eth:0x...",
  "amount": "12.5",
  "currency": "ETH",
  "policy": "org:default"
}

Frequently Asked Questions

1. Is Trézór Bridge custodial?
No. Trézór Bridge provides secure connectivity and coordination without taking custody of private keys or funds. Signing can be performed on-device, in hardware security modules, or via an integrated MPC provider depending on your chosen configuration.
2. How does Trézór Bridge ensure transaction privacy?
Transactions and metadata are encrypted in transit and at rest. Only authorised auditors and the sending parties (as permitted by policy) can access sensitive metadata. The bridge supports selective disclosure features and privacy-preserving routing where required.
3. Which blockchains and wallets are supported?
Trézór Bridge supports major EVM chains, Bitcoin, and several L2 environments out-of-the-box, and offers adapters to connect to custodial APIs and popular wallet protocols. Custom adapters can be developed using the Bridge SDK.
4. What compliance features are included?
Built-in logging, transaction tagging, KYC/AML hooks, and exportable audit trails make compliance straightforward. You can configure policy checks to block or flag transfers that violate regulatory or internal rules.
5. How do I start integrating?
Sign up for an integration account, get API keys for the sandbox, and follow the quickstart guide. The developer console includes sample keys, a sandbox ledger, and step-by-step examples to run your first test transfer.
