Rebar Labs is an organization building products and infrastructure for Bitcoin, with a focus on the emergence of Bitcoin MEV. We’re empowering Bitcoin's ecosystem to address MEV, ensuring fair markets and providing new opportunities for users and miners.

MEV stands for Maximum Extractable Value. It refers to the potential profits that can be earned by strategically ordering, including, or excluding transactions within a block on a blockchain network. MEV first appeared on Ethereum, and we expect it to grow on Bitcoin as well.

MEV is emerging on Bitcoin alongside the introduction of new token standards, metaprotocols, and decentralized finance — for example: Ordinals, Runes, and BRC-20s. Instances of MEV on Bitcoin include sniping for mints and trades, exploiting the "first is first" principle in BRC-20 minting, and potential frontrunning on decentralized exchanges for these tokens.

Rebar Labs is addressing Bitcoin MEV through three main areas: building infrastructure (allowing for MEV-protected transactions), creating products (beginning with data analytics tools), and conducting research (providing analysis on new activities and instances of MEV on Bitcoin). Our goal is to help both users and miners navigate the challenges and opportunities presented by MEV.

For users, Rebar Labs provides infrastructure to defend against MEV strategies that could impact market fairness, such as frontrunning or sniping. For miners, we offer opportunities to subsidize mining revenue with our new infrastructure as block rewards diminish.
