OP Stack

Conduit allows you to launch a rollup in a fraction of the time with the OP Stack.

OP Stack is the premiere open-source rollup implementation. You get:

  • 10-100x cheaper fees than Ethereum Mainnet
  • Interoperability with Mainnet through trustless bridging
  • Ethereum Equivalence, so you can use the same workflows and tooling
  • Improved node performance, so you can get thousands of transactions per second

Below is a great primer on how the OP Stack works to bring you more performance while maintaining security: (Almost) Everything you need to know about Optimistic Rollup

Supported JSON RPC Methods

op-reth implements the standard Ethereum JSON-RPC methods. The supported JSON-RPC methods can be found here.

FAQ

How do I withdraw/bridge tokens?

Please see our guide of using the Conduit SDK alongside the Optimism SDK here.

Can I use a Custom Gas Token (CGT)?

Yes. The OP Stack supports a Custom Gas Token (CGT) self-serve from the deploy dashboard. A CGT replaces ETH as your chain’s native asset for paying gas. It’s treated as the chain’s native token and it must use 18 decimals.

A Custom Gas Token can only be set when your chain is deployed. It cannot be added, removed, or changed after your chain is live, so decide before deploying.

Are there any public audits?

Optimism audits can be found here. Optimism has a security model to support the continuous development they do time by time.

For Celestia based op rollups, you can find the audit here.

Will my rollup come with any pre-deployed contracts or preinstalls?

Yes, when launching a rollup on the OP Stack, several core contracts come preinstalled, allowing you to move to production faster. These pre-deployed contracts include Safe, SafeL2, Multicall3, MultiSend, MultiSendCallOnly, create2 Proxy, create2deployer, Safe Singleton Factory, permit2, ERC-4337 Entrypoint v0.6.0. For more details, visit the official Optimism documentation.

To deploy your own Safe (multisig) wallet using the preinstalled factory, see our guide to deploying a Safe.
