FIP.16

Restructure FLR Tokenomics for Long-Term Sustainability

FIP.16 reduced annual FLR inflation by 40%, raised the base gas fee 20x to accelerate network burns, introduced a minimum 20% FTSO provider fee floor, and created FIRE - a new entity that channels protocol revenue into open-market FLR buybacks and burns.

Hard Fork Activation

FIP.16's fee and economics changes ship in a coordinated hard fork. This panel flips to active the moment the base fee floor goes live on chain.

Net Issuance

Annual FLR minted (inflation) against annual FLR burned (gas). FLR turns net deflationary only when burns exceed new issuance.

Gas Burn, Before vs After

The FIP.16 hard fork went live on 2026-07-14, raising the base fee floor from 25 gwei to 500 gwei (20x). Burns now track the higher base fee; the chart below shows the daily total as indexed gas data catches up.

FTSO Epoch Rewards

Total FLR distributed to FTSO data providers per reward epoch. The 40% inflation cut directly reduces this pool.

Supply Projection: Mint vs Burn

Estimated annual FLR issuance vs burns under FIP.16 parameters. Burns grow as transaction volume increases.

FDC Fee Revenue, Going to FIRE

Each FDC attestation request still costs a flat 1 FLR, shown here from the fee emitted on-chain. The base-fee hard fork did not change this: the FIP.16 fee schedule (3-20 FLR by type, 90% routed to FIRE) is contract-gated and activates separately. This section flips automatically when the on-chain fee changes.

FTSO Provider Fee Distribution

FIP.16 enforced a 20% minimum delegation fee. Research shows all 98 active providers are at exactly 20%.

Inflation Rate: FLR vs Other L1s

With FIP.16, FLR drops from 5% to 3% annual inflation, still above ETH and BNB but below SOL. Gas burns push it further down.

Validator Migration, P-chain 5x Weight Boost

FIP.16 gives P-chain validators 5x reward weight vs C-chain delegation. Current P-chain: 14.05B FLR staked across 152 validators.

Pre-FIP.16 P-chain and C-chain had equal reward weight. With FIP.16, validators who secure the network on P-chain now receive 5x more reward weight, a strong incentive to migrate from C-chain delegation.

PENDINGH2 2026 (estimated)

Blocks built inside FCC. STP.13 put FCC to a Songbird governance vote (closed Jul 12, 2026) as a first step; mainnet timing is not set.

FUTURE2027+ (estimated)

FIRE-assigned entity controls both block building and proposal.

FIRE treasury address: Not yet deployed. The FIRE contract will be published by the Flare Foundation post-hard fork. This dashboard will automatically link to the treasury address once available.

Mint is recognized inflation from the Inflation contract; burn is the current gas-fee run-rate measured live from recent blocks (the 500 gwei base fee is now active). FLR turns net deflationary only once burns exceed new issuance, which needs far more on-chain activity than today. Read live from chain.

flr://fire_watchWATCHING
Buyback and burn entity
Not yet on-chain

FIRE is the FIP.16 mechanism that uses a share of network revenue to buy FLR on the open market and burn it. Its funding is meant to come from a portion of data attestation fees, MEV captured by the protocol, and FAssets fees. No FIRE address has been registered on-chain yet, so there is nothing to measure.

This panel reads the contract registry on every load and lights up automatically the moment a FIRE address is registered. Until then, the net issuance above stays inflationary.
