The Flare DVN confirms each message only when a stake-weighted majority of Flare's 100 data providers agrees. Asset issuers can add it to their security stack from early December.
Asset issuers that use the OFT Standard, including Tether, PayPal, Paxos, Ondo and Anchorage Digital, choose which DVNs must attest to a message and agree before it completes. A wider choice of verifiers lets each issuer build a setup that fits specific security needs and requirements.
Flare is joining as one of those DVNs. It draws on Flare’s Network of Data: 100 independent data providers, the same validators that secure the Flare blockchain, so no single operator decides what gets verified. It’s the same verification that already secures FAssets, Flare’s system for bringing non-smart-contract assets like XRP to DeFi.
Issuers can add Flare alongside the verifiers they already use. An issuer that sets the Flare DVN as required makes Flare's verification binding. If the Flare DVN does not vote, the message does not complete.
How It Works
The Flare DVN is built on Flare Data Connector (FDC), Flare's system for network-level consensus on external chain data.
- Independent checks. Each of Flare's 100 independent data providers checks the source chain on its own.
- Stake-weighted agreement. A message is confirmed only when a stake-weighted majority agrees.
- Proof on the destination chain. Flare’s Relay makes FDC results verifiable on each supported EVM chain, starting with Flare and Ethereum. Smart contracts verify the proof before the message can execute.
- Permissionless delivery. Anyone can deliver the proof and relay the consensus from Flare to each destination chain. Flare also runs several independent operators for liveness and redundancy.
- Checks before the vote. The verifier contract checks the FDC result from the source chain and confirms this to the LayerZero endpoint.
Flare Joins a Marketplace of DVN Providers Featuring Leading Global Enterprises
Flare joins a verifier marketplace of 55+ DVN providers. Issuers already use it to build security stacks to their own requirements. Deutsche Telekom MMS, Google Cloud, Fidelity Center for Applied Technology and Blockaid each run a DVN.
An issuer decides which DVNs must sign. An issuer also decides how many must agree. Security teams choose the verification methods they trust. Flare adds full network-level stake-weighted verification to that set.

About LayerZero
LayerZero connects the world's most important assets to the world's most utilized blockchains. Issuers use the OFT Standard to distribute assets to 110+ chains. Chains use LayerZero Endpoints to connect to those assets and users. Wallets and exchanges use the Value Transfer API to move them. Trusted by Tether, PayPal, Paxos, Ondo and Anchorage Digital, LayerZero is the standard for cross-chain interoperability.
About Flare
Flare is the blockchain for data. Its native protocols, FTSO for prices and FDC for verifying events on other chains, form one data stack. That stack first made XRP productive: FAssets turned XRP into FXRP, the largest non-custodial XRP bridge, now on seven networks, and Smart Accounts let holders use it from their XRPL wallets. What began with XRPFi now reaches beyond Flare: the same data verifies cross-chain messages as a LayerZero DVN, backed by 100 independent validators, and Flare Confidential Compute is extending it to private applications. One data stack, making more markets possible.
