What Is Flare?
Flare is an EVM-compatible Layer 1 blockchain designed to make external data and information from other blockchains available to smart contracts. The Ethereum Virtual Machine, or EVM, is the software environment that executes Ethereum-style smart contracts.
FLR is the native asset of the Flare network. It is used for network fees, Proof-of-Stake participation, and other supported network functions.
Flare is notable for integrating data protocols into its network. The Flare Time Series Oracle supplies time-series data, while the Flare Data Connector helps applications verify information about external systems and other blockchains.

Flare is not an Ethereum Layer 2. It has its own network operation, validators, and consensus structure. EVM compatibility means that developers can use Solidity and familiar Ethereum-oriented development tools, but it does not make Flare part of Ethereum or cause the two networks to share the same security.
The Flare network is the blockchain infrastructure. FLR is the network’s native asset, used to pay transaction fees and participate in supported network processes. These terms are related but do not refer to the same thing.
Background and Development of Flare
Flare was developed as data-focused blockchain infrastructure for applications that need information from outside their own smart-contract environment. Its design addresses two broad data requirements: access to time-series information and verification of events or states originating elsewhere.
The supplied project guide identifies July 14, 2022, as the date of the Flare mainnet genesis and January 9, 2023, as the FLR Token Distribution Event. Flare subsequently developed its EVM-based application environment alongside integrated protocols such as the FTSO and FDC.
Protocol capabilities, participation conditions, and token-economy policies can change through technical development and governance. Current operational details should therefore be checked against up-to-date official documentation rather than inferred from historical descriptions.
How Does Flare Work?
Flare combines a smart-contract platform, a Proof-of-Stake network, and integrated data protocols. Each part serves a different purpose.
EVM-compatible smart contracts
Flare’s EVM compatibility allows developers to build applications with Solidity and other tools commonly associated with Ethereum development. These applications run on Flare as an independent network.
Proof-of-Stake operation
Validators participate in network consensus and security by staking FLR. Proof-of-Stake uses committed native assets as part of the process for operating and securing a blockchain, rather than relying on proof-of-work mining.
Flare Time Series Oracle
The Flare Time Series Oracle (FTSO) is a decentralized data protocol that provides time-series information to applications on Flare. Its primary role includes supplying asset-price and related time-series data submitted through a network of data providers.
Applications can use this information in smart contracts, but an oracle does not eliminate the possibility of inaccurate submissions, unexpected aggregation results, or problems caused by rapidly changing markets.
Flare Data Connector
The Flare Data Connector (FDC) is designed to make verified information about external systems and other blockchains available to Flare smart contracts. A request concerning an external event can be assessed through the protocol and, when its conditions are met, made available in a form that applications can use.
The distinction is important: the FTSO focuses on time-series data, while the FDC focuses on verifying external or cross-chain events and states.
Key Features of Flare
- EVM compatibility: Flare supports Ethereum-style smart contracts and familiar development tools while remaining an independent blockchain.
- Integrated time-series data: The FTSO provides decentralized data feeds for use by Flare applications.
- External event verification: The FDC is designed to verify supported information from other blockchains and external systems.
- Native network asset: FLR is used for transaction fees, staking, and other supported network functions.
- Wrapped FLR: WFLR is the ERC-20-compatible wrapped form of FLR used with smart contracts and supported on-chain functions.
- Data-provider delegation: WFLR holders can use supported delegation mechanisms to assign voting power to FTSO data providers without treating delegation as a transfer of the underlying asset’s ownership.
- Data-dependent applications: Systems such as FAssets are designed to combine price data, external-chain verification, collateral, and other protocol components.
Some functions depend on current protocol support, interfaces, and participation rules. Their availability and conditions may change, so users and developers should confirm current details in official documentation.
FLR, WFLR, Staking, and Delegation
What is FLR used for?
FLR is Flare’s native asset. It is used to pay network fees and can be used in validator staking and other supported network activities. As a native asset, FLR exists at the network level rather than solely as a smart-contract token.
How does WFLR relate to FLR?
WFLR, or Wrapped FLR, is an ERC-20-compatible form of FLR. Wrapping allows the value represented by native FLR to be used with smart contracts and supported functions such as FTSO delegation.
FLR and WFLR are connected, but they use different technical formats. A service may require one form rather than the other, so users should verify the required asset and official contract information before interacting with it.
Validator staking versus FTSO delegation
Validator staking supports network consensus and security. It involves staking FLR with a validator under the network’s applicable participation conditions.
FTSO delegation supports the data system instead. It assigns WFLR voting power to a data provider participating in the FTSO. Delegation and validator staking therefore have different purposes and should not be treated as interchangeable processes.
Rewards from either activity are variable rather than guaranteed. Results may depend on protocol rules, provider or validator performance, participation levels, and changes in FLR’s market value.
Practical Uses of Flare
Developers may encounter Flare when building smart contracts that require data not generated directly by the application. Potential contexts include decentralized finance, price-dependent contracts, services that respond to activity on another blockchain, and applications built around cross-chain information.
Example: A lending application could use an FTSO price feed when evaluating collateral. This is an illustrative scenario, not a statement that a particular application is available or safe.
Example: An application could use the FDC to obtain verified information about a supported event on another blockchain before carrying out an action on Flare. The exact events and networks supported depend on current protocol documentation.
FAssets are intended to let assets from blockchains with limited smart-contract functionality be represented and used within Flare’s on-chain environment. Such a system may depend on collateral, agents, price information, and external-chain transaction verification.
Use of the FTSO, FDC, or another Flare component does not guarantee the security of an application. Users must also consider its smart contracts, collateral design, operators, interfaces, and other dependencies.
Advantages, Limitations, and Risks
Potential advantages
- Integrated data access: Flare provides network-level protocols for time-series and externally verified data, reducing the need for each application to design every data mechanism independently.
- Developer familiarity: EVM compatibility allows developers to use Solidity and established Ethereum-oriented tools.
- Different data functions: The FTSO and FDC address distinct needs instead of treating all external information as one type of data.
- Cross-chain application design: Verified external information can support applications that respond to events beyond Flare itself.
Limitations and risks
- Oracle and data risk: Submitted or aggregated data may be inaccurate, delayed, or unsuitable for an application’s assumptions.
- External-chain dependency: Cross-chain applications can be affected by conditions, disruptions, or reorganizations on another network.
- Validator and staking risk: Validator performance and changing participation conditions can affect staking outcomes. Rewards and principal value are not guaranteed.
- Smart-contract risk: Code errors, vulnerabilities, or flawed application design can result in loss.
- Collateral and liquidation risk: Collateralized services may liquidate positions when their conditions are not maintained.
- Interoperability risk: Combining several networks, data providers, agents, or protocols creates additional technical dependencies and failure points.
- Changing protocol conditions: Supported data types, interfaces, staking rules, delegation arrangements, and application features may change.
- Regulatory uncertainty: Laws and regulatory treatment involving cryptocurrencies, decentralized finance, and cross-chain services differ by jurisdiction and may change.
- Market risk: FLR can experience substantial price volatility, which may affect the value of holdings and participation rewards.
Integrated data protocols can be useful infrastructure, but they do not remove the financial, technical, or operational risks associated with blockchain applications.
