Worldpay, Fidelity Center for Applied Technology, Deutsche Telekom, and Google Cloud now operate production verifiers on LayerZero, offering their names as cross-chain security to any application that wants them. This post explains what a DVN is, what each institution has built, and how to compose your own verifier set. If you want to build with this, visit Developers or reach out to our team.
When a payment or asset moves between blockchains, the receiving chain has to be certain the message that arrived is exactly the one that was sent. On LayerZero, providing that certainty is the job of a Decentralized Verifier Network (DVN). A DVN attests to the integrity of a cross-chain message before it is committed to a destination chain. The LayerZero protocol is permissionless, so any organization can operate a DVN, and every application chooses which DVNs verify its messages. Verification authority sits with the application owner, not with the protocol. A DVN plays the role an auditor plays for a set of accounts: an independent party that attests a record is genuine before anyone relies on it.
But most cross-chain protocols are built the other way around. They often ship a single shared validator set, so you pick the protocol and inherit whoever it already trusts. LayerZero offers applications a marketplace of independent verifiers (DVNs) to compose into their cross-chain security stack. Each verifier brings its own name, jurisdiction, infrastructure and reputation. The most consequential names in payments, asset management, telecom, and cloud have entered this marketplace as suppliers.
Worldpay, Fidelity Center for Applied Technology, Deutsche Telekom, and Google Cloud all run production DVNs on LayerZero today. Together their core businesses represent more than $10 trillion in annual financial activity and each one now offers its name as a verifier in the security stacks of stablecoin issuers, tokenized asset issuers, payment applications, and onchain protocols.
Here is what each of them has built.
Operator | Verification focus | In Production |
|---|---|---|
Worldpay (Global Payments) | Stablecoin, tokenized assets, and payment flows | 9 chains incl. Ethereum, Base and Solana |
Fidelity Center for Applied Technology (FCAT®) | Real-world assets, high resiliency, and institutional grade infrastructure | 11 chains incl. Hyperliquid, Ethereum, Solana, and many others. First integrator: Ondo Finance |
Deutsche Telekom MMS | EU-sovereign, GDPR and MiCA aligned | 12 chains, twin German/Dutch data centers |
Google Cloud | Default cross-chain trust anchor since 2023 | In the BitGo (wBTC) and PYUSD stacks |
Verifying Cross-Chain Payments at Enterprise Scale with Worldpay
"As Payments DVN operator, we're proud to be able to enable enterprise-grade, on-chain verification and messaging for our global merchant base whether they're leveraging stablecoins, tokenized assets, or other on-chain payment flows across multiple blockchains. This marks a significant step forward in enabling our partners to operate with confidence, knowing their cross-chain payment operations are safeguarded by Worldpay's industry-leading standards."
Ahmed Zifzaf, Head of Crypto Partnerships, Worldpay/Global Payments
Worldpay, together with Global Payments, is one of the largest merchant acquirers in the world, processing more than 94 billion transactions and $3.7 trillion in annual volume across six million merchants. In March, Worldpay launched its Payments DVN on LayerZero, bringing decades of payments compliance posture to cross-chain message verification across Ethereum, Base, Solana, and six other chains.
The Payments DVN is purpose-built for stablecoin flows and cross-chain payment operations. Any application moving value across chains can now include Worldpay as a required signer in its security stack, giving its compliance organization a widely-recognized name in global finance. The product is not Worldpay verifying Worldpay. It is Worldpay verifying for everyone else.
Institutional-Grade Verification for Tokenized Assets with Fidelity Center for Applied Technology (FCAT®)
"As interoperability pushes the blockchain industry forward, infrastructure plays a critical role. The FCAT DVN was purpose-built for that role, reinforcing LayerZero's modular security model with resilient, independent validation that strengthens the integrity of cross-chain messaging. In turn, builders gain trusted and scalable verification that preserves the benefits of LayerZero's open, permissionless architecture."
Jason Ward, Head of FCAT Blockchain and Crypto
FCAT launched it's DVN on LayerZero earlier this year, validating messages across Ethereum, Arbitrum, Base, Optimism, Polygon, Avalanche, and Solana. FCAT serves as an innovation catalyst for Fidelity Investments, delivering transformative solutions through cutting-edge research, experimentation, and product development. Its DVN enables applications to diversify their security stacks with a solution built to meet institutional standards. Tokenized asset issuers needed a verifier recognized by compliance officers at regulated institutions. FCAT's DVN delivers just that.
Ondo Finance, which manages more than $2.5 billion in tokenized treasuries, equities, and yield-bearing products, signed on as the first integrator. Ondo has set a pattern that other tokenized asset issuers can follow.
Sovereign European Infrastructure with Deutsche Telekom
"Our collaboration with LayerZero enables institutional clients to benefit from smooth, inter-chain transactions supported by robust security and sustainable practices."
Eugenio Carlon, Portfolio and People Cluster Lead Digital Trust and Cyber Security, Deutsche Telekom MMS
Deutsche Telekom is one of the largest telecommunications companies in the world, and its subsidiary Deutsche Telekom MMS operates a DVN on LayerZero built on Open Telekom Cloud, with twin-core data centers in Germany and the Netherlands. The infrastructure is GDPR-compliant and runs on 100 percent renewable energy. It is purpose-built for European institutional clients, including banks, stablecoin issuers, and exchanges that need a verifier inside their own regulatory perimeter.
The Deutsche Telekom DVN currently secures messages across Ethereum, Solana, Arbitrum, Avalanche, Base, BNB Chain, Linea, Mantle, Polygon, Optimism, Gnosis, and Fantom. For a European stablecoin issuer building toward MiCA compliance, a Deutsche Telekom signature on every cross-chain transfer is no longer hypothetical. The verifier is live and selectable today.
A Cross-Chain Trust Anchor with Google Cloud
"The Google Cloud oracle is meant to serve as the https of cross-chain messaging. Just like they verify all https certificates to attest to the validity of the website, the Google Cloud oracle is now additionally verifying all LayerZero messages by default."
Google Cloud has operated a DVN on LayerZero since September 2023, making it one of the longest-running verifiers in production. The framing at launch was that the verifier should extend Google's existing role as a trust anchor for the internet, attesting to the integrity of cross-chain messages the same way Google attests to TLS certificate validity today.
The Google Cloud DVN sits in many of the most widely used security stacks on the network. BitGo selected it as part of the verifier set for wrapped Bitcoin. PYUSD includes it alongside Paxos and LayerZero Labs. For any application that wants Google as a name in its security configuration, the verifier has been selectable for three years already.
A Marketplace for Verification
These four institutional verifiers sit alongside more than 50 DVNs on the network, spanning every category of verification methodology:
- zk-based verifiers. Polyhedra and others prove message validity cryptographically.
- Hardware-attested verifiers. Canary runs inside AWS Nitro enclaves.
- Infrastructure operators. Established node operators like Nethermind and Blockdaemon.
- Issuer-run verifiers. Operated directly by the institutions whose assets they sign: BitGo for wrapped Bitcoin, Paxos for PYUSD, Ondo for its tokenized funds, and Ubisoft for player-owned game assets.
Every application composes its own configuration, and every issuer can install whichever verifiers it wants as required signers. The protocol stays unopinionated about who qualifies, the DVN marketplace is permissionless on both sides.
Compose Your Stack, Or Run Your Own
If you are a stablecoin issuer, a tokenized asset issuer, a payment application, or an onchain protocol moving value across chains, you can compose a security stack today that includes Worldpay, Fidelity’s Center for Applied Technology, Deutsche Telekom, Google Cloud, or any combination of the more than 50 verifiers live on the network. You choose which names your compliance organization recognizes, which jurisdictions your regulator understands, and which verification methodologies your security team trusts. The architecture lets you choose.
If you are a Tier 1 institution that sees itself missing from this list, the same permissionless property applies in reverse. Any organization that can attest to the validity of a cross-chain message can run a DVN. The roster of enterprise verifiers will grow, because demand for institutional names in cross-chain security stacks is growing faster than the supply.
Start Building
The DVN marketplace is open today. Choose your verifiers and configure the security model your application requires, from a single trusted name to a multi-party stack spanning several jurisdictions and methodologies.
