Guide to Migrating Ethereum L2 to an EVM Layer 1

The migration from Ethereum Layer 2 to an EVM Layer 1 is becoming more relevant as needs for network control, interoperability, and token economic flexibility increase. This move allows a blockchain to remain compatible with Ethereum while operating independently as a Layer 1. This article covers the concept, technical stages, and interoperability implications of that migration in a concise and easy-to-understand way.

Key Takeaways:

• Migration can be performed without significant changes for users

• EVM smart contracts continue to run without rewriting

• Native Ethereum interoperability is preserved

Reasons to Migrate from Ethereum L2 to EVM Layer 1

Migration from Ethereum L2 to EVM Layer 1 is generally pursued when a project needs full control over its network. On Layer 2, many aspects such as transaction execution and fee determination still rely on certain infrastructure components, including sequencers.

By becoming an EVM Layer 1, a blockchain gains full autonomy over block time, transaction fees, and network management. Although independent, compatibility with the Ethereum Virtual Machine is retained, allowing all smart contracts to run without significant changes.

This approach also reduces long-term dependence on other networks. For projects whose application ecosystems are starting to grow, Layer 1 is often seen as more flexible and sustainable than Layer 2.

How to Move from Ethereum L2 to EVM Layer 1

1. Set up the EVM Layer 1 node
   The first step is to run a Layer 1 node that supports EVM and is configured according to the network’s requirements, such as block time and other base parameters.
2. Temporarily stop the Layer 2 sequencer
   The Layer 2 sequencer is halted to freeze the network state so that no status changes occur during the migration process.
3. Extract smart contracts from Layer 2
   All smart contract bytecode running on Layer 2 is extracted to ensure application logic remains the same after migration.
4. Compose the Layer 1 genesis
   The smart contract bytecode is inserted into the Layer 1 genesis configuration so contract states remain consistent when the new blockchain is launched.
5. Replay specific transactions if needed
   If there are transactions not captured in the genesis state, those transactions can be replayed individually, although such cases are relatively rare.
6. Redirect RPC endpoints to Layer 1
   After the Layer 1 network is active, wallet and application RPC endpoints are pointed to the new network without requiring action from users.
7. Permanently deactivate Layer 2
   Once all functions run stably, the Layer 2 network can be fully shut down and operations continued on Layer 1.

Ethereum Interoperability and Tokens as Gas Fees

Ethereum interoperability is an important element in this migration. With native interoperability support, an EVM Layer 1 can connect directly to the Ethereum mainnet without centralized intermediaries. This preserves liquidity and connectivity between networks.

Additionally, Layer 1 allows the use of the project’s own token as gas fees. This approach adds utility to the token and aligns the network’s economics with user activity. Another option that can be enabled is staking the token as a security mechanism, although that is optional.

This model shows that migrating to an EVM Layer 1 is not only a technical change but also an economic redesign to make the blockchain more independent and efficient.

Conclusion

Migrating from Ethereum L2 to EVM Layer 1 provides full control over the network without sacrificing Ethereum compatibility. By retaining smart contracts, the user experience remains consistent, while native interoperability ensures cross-network connectivity. Although it requires careful technical planning, this approach offers flexibility, efficiency, and a long-term foundation for EVM-based blockchain development.

FAQ

Does migration from Ethereum L2 to Layer 1 affect users?

Not directly, since addresses, assets, and smart contracts remain the same.

Do smart contracts need to be rewritten after migration?

No, as long as the Layer 1 fully supports EVM.

How long does the migration process usually take?

Typically only a few days with proper technical preparation.

Is interoperability with Ethereum still available?

Yes, native interoperability allows direct connection to the Ethereum mainnet.

Can the project’s token be used as gas fee?

Yes, andthis is often one of the primary goals of migrating to Layer 1.
