| Variable | Scope | Description |
|---|---|---|
| ALCHEMY_ROLLUP_RPC_URL | Client | RPC endpoint for the deployed Alchemy rollup (provided in the Alchemy dashboard). |
| ALCHEMY_API_KEY | Server | Alchemy API key for the rollup's managed RPC, indexers, and gas-manager policy. |
Use Alchemy Rollups to provision the chain. In the Alchemy dashboard pick a stack (OP Stack or Arbitrum Orbit), DA layer (Ethereum blobs, Celestia, EigenDA, or Avail), settlement layer, and gas token. After deployment use the issued RPC URL, chain ID, and Alchemy-hosted Blockscout/explorer; wire Alchemy Smart Wallets and the Gas Manager so users can transact with sponsored, AA-native UX from launch. Treat the sequencer as Alchemy-managed unless you opt into shared sequencing.
- ⚑DA layer choice is locked at deploy time — switching from Ethereum blobs to Celestia/EigenDA/Avail later forces a chain migration and new state root.
- ⚑DA inclusion latency depends on the chosen layer (Ethereum blobs ~12s, Celestia ~12s, EigenDA sub-second, Avail ~20s) and bounds your soft-finality.
- ⚑Custom (non-ETH) gas tokens on Orbit chains break many wallets and indexers — confirm ecosystem support before locking the gas token.
- ⚑The default sequencer is centralized and operated by Alchemy; opt into Espresso or another shared sequencer for credible neutrality.
- ⚑Settlement-layer choice (L1 Ethereum vs an L2 for L3s) defines fork rules and withdrawal cost — L3s inherit liveness assumptions from their parent L2.
- ⚑Withdrawal finality follows the underlying stack (7-day OP/Orbit challenge window) unless you layer a fast-finality AVS on top.
- ⚑Mainnet rollups carry meaningful monthly cost plus DA pass-through fees — model unit economics before launch.
