A secure, human-first bridge for Web3 — hardware-backed, privacy-first
Trezõr® brïdge® is a modular gateway that connects wallets, dApps, exchanges and custodians across chains while keeping safety and user control front and center.
Built around hardware-assisted key custody, verifiable attestations, and a privacy-respecting UX, brïdge® makes it simple to move value, sign messages, and authorize contracts without sacrificing control.
Hardware-backed custody
Plug directly into hardware devices and FIDO tokens. Private keys never leave secure elements — we orchestrate signed transactions while keeping users in control of every operation.
Cross-chain interoperability
Seamlessly transfer and interact with assets across EVM chains, Cosmos zones, and smart contract platforms via secure relays and audited validators.
Privacy by design
On-chain interactions are minimized, metadata is compartmentalized, and optional on-device approvals keep your footprint small and your privacy intact.
Instant developer APIs
Well-documented REST and SDKs for JavaScript, Rust, and Go make it easy to add secure signing, multisig flows, and hardware authentication to your dApp.
Patented • Audited • Composable
Why choose Trezõr® brïdge®?
Complexity in Web3 often leads to compromises: convenience traded for safety, or speed at the expense of clarity. Trezõr® brïdge® fixes that by offering a single layer that is both developer-friendly and user-centric.
We bind cryptographic assurances to clear human prompts, provide optional multisig schemes for shared custody, and integrate with institutional compliance tools without leaking user intent or secrets.
“We designed brïdge® so teams can deploy cross-chain features quickly while preserving end-user sovereignty.”

Core guarantees
Keys anchored to tamper-resistant hardware
Replay-protected cross-chain relays
Zero-knowledge-friendly attestation points
Auditable, upgradable policy engines for enterprise teams
For developers — build with confidence
Ship integrations with concise APIs and robust client libraries. Whether you need hosted relayers for meta-transactions, on-prem broker nodes for private deployments, or SDKs that bind to hardware keystores, brïdge® offers multiple deployment patterns.
Our sample flows include single-shot contract signing, delegated custodial operations with on-chain verifiable receipts, and modular plugins for liquidity routing and cross-chain settlement.
Highlights for engineers
Idempotent transaction orchestration across chain boundaries
Webhooks + push notifications for human approvals
Pluggable policy engine to enforce whitelists and spend caps
Audit-mode: cryptographic proofs and verifiers for compliance teams
Ready-made examples and templates let you go from zero to a working integration in hours — not weeks.
Get started
Try our hosted sandbox or request an enterprise deployment with private relayers and SLA-backed support. We offer on-boarding workshops, security reviews, and optional managed hardware for teams that want an end-to-end solution.
For pricing and pilot programs, contact our partnerships team or sign up for early access to the SDK beta.
No. Keys remain in the secure element or hardware keystore. brïdge® transmits signed payloads and verification receipts only when authorized by the user's on-device approval.
Which chains are supported?
We support major EVM chains, several Cosmos-based networks, Solana (via dedicated adapters), and additional chains through our plugin architecture. Reach out for custom integrations.
How does recovery work?
Multiple recovery patterns are available: social recovery, time-locked guardian workflows, and institutional key-splitting using threshold signing. Recovery options are configurable per deployment.
