FastLane Labs is a blockchain infrastructure provider building maximal extractable value (MEV) and liquid staking products on the Monad blockchain. Its core products are shMON, a liquid staking token that pairs staking rewards with revenue from FastLane's on-chain MEV auction and holds the majority of Monad's liquid-staking TVL; Smart Vault, a USDC-denominated yield product; and hMON, a yield-donation token. FastLane operates a public, on-chain MEV auction that a majority of Monad validators route blocks through, exposing developer surfaces for searchers (the FastLane Sidecar and auction-handler contracts), validators (a Leader API and validator onboarding), and stakers. It also maintains Atlas, an open-source execution-abstraction framework, with a Go SDK and JSON-RPC tooling published on GitHub. Developer integration is via JSON-RPC APIs and Solidity smart contracts rather than a REST/OpenAPI catalog.
