LayerZero OFT (Bridge)
Yuzu Alpha (yzUSD, syzUSD, yzPP)
LayerZero is the leading omnichain interoperability protocol, connecting 100+ blockchains and securing cross-chain messaging for protocols including Stargate, Ethena, PancakeSwap, and USDT0, with over $75B in cumulative transfer volume. LayerZero V2's modular security stack lets each application configure its own set of Decentralized Verifier Networks (DVNs) and thresholds, giving integrators direct control over the verification trust model rather than inheriting a fixed validator set.
Yuzu Money uses LayerZero V2 to carry yzUSD, syzUSD, and yzPP across Plasma, Ethereum, Monad chains. Three DVNs per pathway on a 3-of-3 required threshold were configured, where all three must attest to a message before it is accepted on the destination chain. DVN set selection was chosen with the explicit goal of eliminating correlated failure modes across infrastructure, client implementation, verification approach, and jurisdiction.

Selection Framework
The three DVNs in our set are intentionally non-overlapping across:
Verification approach: multisig with economic restaking, hardware-isolated TEE attestation, enterprise telco-operated signing
Client implementation: Gasolina (TypeScript) and Canary's independent Go rewrite
Infrastructure: AWS, Canary's TEE hardware, and Deutsche Telekom's Open Telekom Cloud
Jurisdiction: United States, Switzerland, and Germany/EU
Each DVN contributes at least one property that no other DVN in the set can replicate.
Traditional DVN selection asks "can I trust this verifier?" Our framework asks "if one verifier fails, will another fail at the same time?" Three DVNs sharing the same client and cloud provider are nominally diverse but functionally a single point of failure — a client-level zero-day or a cloud region outage affects all three simultaneously.
Decentralized Verifier Networks (DVNs)
LayerZero Labs — the protocol team's own DVN, backed by economic restaking via EigenLayer. Attackers attempting to forge an attestation face not only key compromise but slashable stake held by an independent set of restakers. This is a class of security property no other DVN in the ecosystem offers today. LayerZero Labs operates with the deepest integration knowledge of the protocol itself and has the strongest reputational alignment — a compromise of their own DVN would be existential to the wider network.
Canary — the verification-diversity pillar of the set. Canary runs signer keys inside hardware-isolated Trusted Execution Environments (TEE) so that even a full host compromise cannot extract the signing material. Canary also ships its own Go client, a complete rewrite of the DVN verifier that shares no codebase with Gasolina (the TypeScript reference client used by most other DVNs). This gives the set resilience to any Gasolina-specific zero-day. Canary is the only DVN in our stack using hardware-based attestation and the only non-Gasolina client available to us.
Deutsche Telekom — the infrastructure-diversity pillar. Deutsche Telekom runs its DVN on Open Telekom Cloud, its own sovereign infrastructure — not AWS, GCP, or Azure. The LayerZero DVN ecosystem is heavily AWS-concentrated; an AWS region outage, zero-day, or jurisdictional action would simultaneously affect most validators available today. Deutsche Telekom is the only meaningful cloud-provider diversity in the set. Operating under German and EU law, it also adds jurisdictional separation from US-based operators and brings the operational standards of a top-tier global telco (SLAs, auditability, enterprise-grade change management) to the verification layer.
