Flare published a governance proposal on Thursday that would make it one of the first layer-1 blockchains to capture maximal extractable value (MEV) at the protocol level rather than letting it flow to the small number of specialized actors who profit from transaction ordering across virtually every major chain.
MEV is the revenue that block builders extract by reordering, inserting or censoring transactions within a block. On most blockchains, this value flows to external searchers and builders who effectively impose a hidden tax on ordinary users through front-running, sandwich attacks and arbitrage.
External estimates put annual MEV revenues at tens of millions on networks like Arbitrum, upwards of $500 million on Ethereum, and as much as $1 billion on Solana. Flare's three-stage proposal would route the revenue into the protocol's own token economics.
In the first stage, block building moves from individual validators to a designated builder, initially run by the Flare Entity, with a fallback to the current model if the builder is unavailable. In the second, block building moves into Flare Confidential Compute, making the process publicly auditable. The third stage merges the builder and proposer into a single entity, shifting existing validators to a verification role.
The proposal also creates FIRE, the Flare Income Reinvestment Entity to collect revenue from multiple protocol sources including attestation fees, FAsset and Smart Account fees, confidential compute fees and the captured MEV. FIRE's primary mandate is reducing FLR token supply through open-market buybacks and burns.
Several changes would take effect immediately after approval. Annual FLR inflation would drop to 3% from 5%, with the hard cap cut to 3 billion tokens per year from 5 billion. A 20-fold increase to the base gas fee, from 60 gwei to 1,200 gwei, would raise estimated annual FLR burn from roughly 7.5 million to 300 million at current transaction volumes. Even after the increase, a standard Flare transaction would cost a fraction of a cent.
Flare has deep roots in the XRP ecosystem, having distributed its initial token supply through an airdrop to XRP holders in 2023. Its FAssets system, which has produced over 150 million FXRP, is designed to bring smart contract functionality to assets on blockchains like XRPL that do not natively support it.
The network reports over $160 million in total value locked as of late March 2026, with more than 887,000 active addresses.
