Introducing Blocktime Labs: Programmable Block Execution

Blocktime Labs is building the new rules of on-chain execution. We are not tuning or optimizing old primitives — we are reimagining the block, turning it into a programmable execution environment where capital, computation, external context, and deterministic control are first-class, block-time primitives.

Intra-Block Loans, Builder Execution Extension, Builder Execution Oracle, and Deterministic Block Placement — alone, each is powerful. Together, they let a single bundle borrow capital, run large searches against live mid-block state, resolve external context, and land exactly where it must — all inside the same block.

Our RPC endpoint at rpc.blocktimelabs.com accepts standard Flashbots-compatible orderflow. All submissions are kept private and never forwarded to the public mempool.
