AltLayer
01Description

Restaked rollup framework and no-code RaaS launchpad. Adds three EigenLayer AVSes — VITAL (state verification), MACH (fast finality), SQUAD (decentralized sequencing) — on top of OP Stack, Arbitrum Orbit, ZK Stack, Polygon CDK, or Starknet rollups.

02Best for

  • 02ephemeral/flash rollups for events
  • 03decentralized sequencing (SQUAD)
  • 04multi-stack RaaS deployment
  • 05EigenLayer AVS-secured chains

05Prompt snippet
Use the AltLayer no-code launchpad to spin up a rollup in ~2 minutes. Select a stack (OP Stack, Arbitrum Orbit, ZK Stack, Polygon CDK, Starknet), DA layer (Celestia, EigenDA, Avail, or Ethereum), and a shared sequencer (Espresso/Radius) if needed. Optionally enable the three AVSes: MACH for sub-block fast finality, VITAL for decentralized state verification, and SQUAD for decentralized sequencing. Reference the issued RPC and chain ID from the app.
06Gotchas
  • MACH fast finality only protects users who trust the AVS operator set — confirm operator stake meets your security threshold.
  • Flash/ephemeral rollups settle and tear down on a schedule; do not park long-lived state on them.
  • Each AVS adds operator-set cost; enabling all three on a low-traffic chain is rarely cost-justified.
  • Stack choice changes the gas token model and bridge — Orbit custom gas tokens vs OP Stack ETH-only differ for wallet UX.
  • DA layer fees are pass-through; surge pricing on Celestia/EigenDA can spike L2 gas unexpectedly.
