"Unlike EigenLayer and Jito, which initially focus on exogenous AVSs (e.g., cross-chain bridges, oracles, shared sequencers and other non-mainnet systems), Solayer aims to start with native Solana on-chain dApps (referred to as endogenous AVSs) and assist them in reserving block space and prioritizing transaction inclusion based on the amount of stake delegated to them."
