Modular / DA·EVM
Gelato RaaS
Rollup-as-a-Service platform for one-click deployment of OP Stack, Arbitrum Orbit, Polygon CDK, and zkSync ZK Stack chains, with Gelato's bundled Web3 Functions, VRF, Relay, and Oracles native to every rollup.
- 01OP Stack / Orbit / CDK / ZK Stack rollups
- 02app-specific L2/L3 chains
- 03rollups needing native automation (Web3 Functions, VRF)
- 04gasless UX via Relay
- 05managed sequencer ops
| Variable | Scope | Description |
|---|---|---|
| GELATO_RAAS_RPC_URL | Client | RPC endpoint for the deployed Gelato rollup (provided in the Gelato dashboard). |
| GELATO_API_KEY | Server | Gelato dashboard API key for programmatic chain config, Relay sponsorship, and Web3 Functions. |
Use Gelato RaaS to provision the rollup. In the Gelato dashboard, choose a stack (OP Stack, Arbitrum Orbit, Polygon CDK, or zkSync ZK Stack), DA layer (Ethereum blobs, Celestia, EigenDA, or Avail), settlement layer, and gas token. After deployment, wire your app to the issued RPC URL, chain ID, and Blockscout explorer; opt into Gelato's bundled middleware (Relay for gasless txs, VRF for randomness, Web3 Functions for automation) since they ship native to every Gelato chain. Treat the sequencer as Gelato-managed unless you explicitly opt into shared sequencing (e.g. Espresso).
- ⚑Stack choice is locked at deploy time — moving from OP Stack to Orbit/CDK/ZK Stack later requires a fresh chain and migration.
- ⚑DA inclusion latency varies by layer (Ethereum blobs ~12s slot, Celestia ~12s block, EigenDA sub-second, Avail ~20s) and dictates your minimum soft-finality.
- ⚑Custom (non-ETH) gas tokens break many wallets, indexers, and bridges — verify ecosystem support before committing the token at deploy time.
- ⚑The default sequencer is centralized and operated by Gelato; for credibly neutral apps opt into Espresso shared sequencing or run your own.
- ⚑Settlement-layer choice (Ethereum L1 vs an L2 for L3s) determines fork mechanics and withdrawal cost — L3 settlement to an L2 is cheaper but inherits that L2's liveness.
- ⚑Withdrawal finality follows the chosen stack (7-day OP/Orbit challenge window, ZK Stack proof cadence) unless you layer a fast-finality AVS like AltLayer MACH on top.
