Flare

Flare is an EVM-compatible Layer 1 that ships data protocols as part of the protocol itself rather than as optional oracles. Its defining feature is that price feeds and cross-chain event attestation are enshrined in the Flare Systems Protocol, so they inherit the network’s economic security instead of depending on a third-party oracle network. Transactions are paid in FLR.

Consensus

Flare runs Snowman++, a Byzantine fault tolerant protocol from Avalanche’s Snow family, and the same client runs on both the P- and C-chains. Snowman++ adds a soft proposer mechanism on top of Snowman: proposer slots are selected deterministically by stake and block height, with up to six proposer windows at five seconds each. That stake-weighted proposer selection is the distinguishing part — it is why Flare describes its consensus as Snowman++ rather than plain Snowman.

Finality is probabilistic rather than deterministic. Flare’s own wording is “near-instantaneous (single-slot) finality”, achieved through Snowball’s stake-weighted confidence counters (Beta) and topological ordering, with a finalisation threshold above 50%. In practice this is far quicker than probabilistic confirmation on chains like Ethereum, but it is a confidence threshold, not a guarantee — so a settlement on Flare is confirmed-on-receipt rather than absolute.

Anyone can run a full node; validation is optional. Validators post proof-of-stake self-bond of at least 1,000,000 FLR, with a 60-day minimum validator commitment and a 14-day minimum delegation period. Flare does not publish a total validator count in its documentation; what it does publish is a fixed 100 data providers, each capped at 3.3% of stake.

Enshrined data protocols

Flare’s differentiator is that its data protocols are part of the protocol itself. The Flare Time Series Oracle (FTSO) provides decentralized price feeds, and the Flare Data Connector (FDC) verifies off-chain actions such as transactions on other blockchains. Both inherit the full economic security of the network because they are enforced by the protocol rather than by a set of independent operators.

These two protocols are what make FAssets possible. FAsset minting relies on FTSO for decentralized pricing and FDC for verifying the lock event on the source chain, so a wrapped asset such as FXRP is backed by real collateral and verified source-chain events rather than by a multisig.

FAssets

FAssets is Flare’s trustless, over-collateralized bridge to networks that have no smart contracts. It creates wrapped representations of assets such as BTC, DOGE and XRP on Flare, backed by collateral and redeemable for the original asset. Because the source networks have no contract layer, backing is enforced through over-collateralization and redemption rather than through a contract on the source chain.

Minting runs through the FAsset minting dApps at fasset.oracle-daemon.com and fassets.au.cc. Wallets documented as supporting FAsset minting include Bifrost, Ledger, Luminite and OxenFlow — Ledger for hardware custody, Bifrost and Luminite as multi-network options, and OxenFlow on iOS.

Tokenomics

FLR pays every transaction fee on Flare, and all FLR spent as fees is burned. FDC fees for malformed or unconfirmable requests are permanently burned as well, and unclaimed inflation rewards are burned after three months. The burn address holds roughly 4.24 billion FLR.

Inflation was reduced from 5% to a 3% target with a hard cap of 3 billion FLR per year under FIP.16, accepted in April 2026. Note that Flare’s public supply figures are inconsistent across sources — on-chain totals around 100 billion FLR sit alongside a “15 billion created” figure in the FIP.01 distribution docs, because the docs distinguish created, distributed and inflationary supply. Around 85–86 billion FLR is circulating.

About 19.8% of distributed supply — the Flare Foundation and Flare VC Fund — cannot vote, so voting power sits with the remaining 80.2%. Governance participation is low, and FIP.16 designates the Flare Foundation as the initial single block builder and administrator of the FIRE entity created to reinvest network earnings.

FLR also serves as FAssets collateral alongside stablecoins and ETH, and its wrapped form WFLR carries delegation weight in the FTSO oracle — capped at 2.5% of WFLR supply to limit any single holder’s influence.

Ecosystem and fees in practice

Flare’s chain TVL is roughly $133M. The largest protocols are Firelight Farm (about $76M, ERC-4626 FXRP vaults and the source of liquid-staked XRP), Kinetic (about $39M, lending), SparkDEX (about $18M, and Flare’s own news calls it the highest-TVL protocol on the chain), Sceptre (about $16M, liquid staking) and Monarq (about $11M, vault risk curation). Enosys, the original flagship DEX, also runs a CDP-based loans product.

FAssets launched on Flare Mainnet in September 2025 with FXRP, which is now the only FAsset live on mainnet — about 145 million FXRP outstanding. FBTC and FDOGE appear in the FAsset interface and roadmap but are **not** enabled on mainnet and have no published launch date, so “Flare bridges Bitcoin” is currently a roadmap claim rather than a shipped one.

Gas is close to free: at a 500 gwei base fee a simple 21k-gas transfer costs roughly 0.01 FLR, well under a tenth of a cent. Non-gas protocol fees matter far more in practice — FDC attestations cost around 1 FLR (rising to 20 under FIP.16), and Web2Json attestations 100 FLR. There is no cleared-XRP or cUSD gas abstraction; FLR is the gas asset, though gasless USD₎0 and FXRP transfers are available through relayer and EIP-712 patterns.

Two further cautions: FlareDatasets is dead — the domain no longer resolves and it has been removed from Flare’s navigation, superseded by FDC and FTSOv2 — and the public RPC is pruned, so historical state queries need an archive node.

Bridges and indexing

Beyond FAssets, Flare is connected by LayerZero V2, Stargate V2 and zkBridge, and carries omnichain fungible tokens including USD₎0, flrETH, USDC.e, WETH and USDT. FXRP is itself an omnichain fungible token with routes to Ethereum, Base, BNB Chain, Monad, Katana, HyperEVM and Hyperliquid, signed by four independent DVNs.

Worth noting for anyone expecting a canonical FLR bridge: there is not one. FLR is the gas asset and moves by exchange rather than by bridge. flrETH is Dinero’s liquid-staked ETH, not a FLR derivative.

Indexing is supported by Envio, Goldsky, sqd and SubQuery, with Dune providing chain analytics. Wallet SDKs include Turnkey, Wagmi, MetaMask Embedded Wallets, RainbowKit and Etherspot.
