# OP Stack and the Superchain: shared software versus shared guarantees

OP Stack is reusable software for building rollup networks; OP Mainnet is one deployment. The Superchain ecosystem coordinates compatible chains and shared configuration or upgrade practices, but each chain still has its own identity and state. Registry inclusion and shared code are useful facts to inspect, not proof that every deployment has identical settings, governance or asset routes.

## Key facts

- **Software:** OP Stack is a component stack, not one account balance or chain. ([OP Stack overview](https://docs.optimism.io/stack/getting-started))
- **Registry:** The Superchain Registry records participating chains and their configurations. ([Join the Superchain Registry](https://docs.optimism.io/chain-operators/guides/join-superchain-registry.md))
- **Configuration:** The registry distinguishes standard and custom deployments. ([Join the Superchain Registry](https://docs.optimism.io/chain-operators/guides/join-superchain-registry.md))

## Keep the toolkit separate from its deployments

A software stack supplies components for execution, transaction ordering, data publication and verification. Operators deploy those components as a particular chain with its own network settings.

Using related code can improve compatibility, but it does not imply the same sequencer operator, administrative controls or every identical parameter.

## Shared software does not merge balances

Suppose two networks use OP Stack and both list the same account address in a wallet. Each network still has its own state. Holding ETH on one does not mean the other has received a deposit.

A route between them needs its own supported messaging or asset-transfer mechanism. A shared ecosystem name alone does not authorize a cross-chain payout.

## Read configuration and upgrade participation

The current registry guide describes standard deployment requirements, a separate custom-chain path and configuration for inheriting coordinated hardfork activations. These fields help explain how a chain participates in the ecosystem.

Check the chain’s actual configuration and deployed contracts before relying on a particular upgrade or security feature. This article does not promise universal interoperability or identical guarantees for every registry entry.

## Questions

### Is OP Stack another name for OP Mainnet?

No. OP Stack is software used to build networks. OP Mainnet is a specific network using that stack.

### Does a Superchain listing prove all chains use identical rules?

No. The registry records configuration and distinguishes deployment types. Inspect the particular chain and feature you intend to use.
