You're running a dApp on Ethereum, and each transaction costs $5–10? Rollup — your own L2 — reduces fees to $0.01 and gives you full control over the gas token and block time. But setting up L2 yourself involves deploying bridge contracts, sequencer, configuring the DA layer, and security. RaaS platforms (Conduit, Caldera, AltLayer) automate 90% of the work, but stack selection, custom gas token, and bridge still require expertise. We are a team of blockchain engineers with 10+ years of combined experience and have helped launch 12+ custom rollups for gaming and DeFi projects. We guarantee consistent uptime and provide certified support via audited smart contracts. We take the project end-to-end: from platform selection to monitoring setup.
What problems does Rollup solve?
- Gas costs: transactions on L1 are expensive, especially for games and NFTs. Rollup reduces them by 10–100 times — up to 80% savings for mass-market applications. That's a drop from $5 to $0.01 per transaction.
- 7-day finality: the standard fraud proof delay hurts UX. We integrate a liquidity bridge that is 100x faster — withdrawals in minutes instead of days.
- DA configuration: choosing the wrong layer leads to overpayment or centralization risk. We'll break down the trade-offs between security and cost.
Choosing an RaaS platform
| Stack | Platforms | DA Layer | Finality | Features |
|---|---|---|---|---|
| OP Stack | Conduit, Caldera | Ethereum, Celestia, EigenDA | ~7 days (fraud proof) | EVM-equivalent, large ecosystem |
| Arbitrum Orbit | Caldera, AltLayer | Ethereum, AnyTrust, Celestia | ~7 days (fraud proof) | Stylus (WASM), low fees |
| ZK Stack (zkSync) | Caldera | Ethereum | Hours (validity proof) | ZK finality, higher proving cost |
| Polygon CDK | AltLayer, Gelato | Ethereum, Avail | Hours (ZK) | Unified Bridge, AggLayer |
For games and NFTs, OP Stack via Conduit is a solid choice. For finance with ZK finality, consider Polygon CDK or ZK Stack. The OP Stack repository is open and battle-tested.
Importance of a custom gas token
A custom gas token allows your users to pay transaction fees in any ERC-20 token, not just ETH. This simplifies onboarding: users can start with USDC and transact immediately without conversion. However, the token must not have rebasing or fee-on-transfer mechanics — these break the gas model. We audit the contract with Slither and run ERC-20 compliance tests before deployment.
Best DA layer for production
DA layer choice affects cost. Comparison:
| DA Layer | Cost (relative) | Security |
|---|---|---|
| Ethereum blobs | Medium | Maximum |
| EigenDA | Low | High (restaked ETH) |
| Celestia | Very low | Medium (own validator set) |
Ethereum blobs after EIP-4844 reduced DA cost by 10–100x. For production, this is the standard. For high-throughput applications, Celestia can save up to 70% compared to Ethereum.
Rollup deployment on Conduit
Conduit is the most popular platform. Conduit RaaS pricing starts at $1,500/month. The deployment process includes configuring the chain, bridge, and custom gas token.
Chain configuration
Set a unique chain ID, block time (2 sec), gas limit, and sequencer parameters. Example config:
chain: name: "MyAppChain" chain_id: 42069 block_time: 2 gas_limit: 30000000 sequencer: fee_token: ETH base_fee_recipient: "0x..." l1_fee_recipient: "0x..." data_availability: type: ethereum l1_chain: mainnet Bridge configuration
The standard OP Stack bridge (OptimismPortal + L1CrossDomainMessenger) is deployed automatically. A critical limitation: L2→L1 withdrawals have a 7-day challenge period. To improve UX, we integrate a liquidity bridge (Across, Hop) that reduces withdrawals to minutes — 100x faster.
Custom gas token
Configured in the genesis config:
const genesisConfig = { gasPayingToken: { addr: ERC20_ADDRESS, decimals: 18, } } Caldera: multi-stack and fast finality
Caldera supports OP Stack, Arbitrum Orbit, and ZK Stack in a single interface. The Mach technology reduces effective finality from 7 days to minutes via an attestation network. You can create a rollup via API for IaC:
curl -X POST https://api.caldera.xyz/v1/rollups \ -H "Authorization: Bearer $API_KEY" \ -d '{ "name": "my-appchain", "stack": "op-stack", "chainId": 42069, "config": { "blockTime": 2, "gasLimit": "30000000", "dataAvailability": "ethereum" } }' AltLayer: restaked rollups and Flash Layer
AltLayer uses EigenLayer restaking for security. Flash Layer is a temporary rollup for high-load events (NFT mint, gaming tournament). It's deployed for hours and then dissolved with state preserved.
