# Start Building

We currently have several environments available, including one mainnet. Ultimately, all of them will be merged into one Layer 2 (L2) solution. 

## **Whitelisting**

You can use SuperLumio canary mainnet without whitelisting, while other testnets/devnets (Optimism testnet and Solana devnet)  require [whitelisting](/start-building/get-whitelisted.md).

Choose the one you prefer:

* [**Optimism SuperLumio**](/start-building/lumio-on-optimism-canary-mainnet.md): the canary mainnet, available on Ethereum, and supports just EVM. It is a pure optimistic rollup based on the Optimism stack.
* [Optimism Testnet](/start-building/lumio-on-optimism-testnet.md):  the testnet network environment combines Move VM and EVM in the same execution environment. It is launched with a modified Reth and Optimism stack. This one will be replaced with a new architecture once the Solana devnet matures.
* [**Solana Devnet**](/start-building/lumio-on-solana-devnet.md): new architecture (Lumio v2), which supports SVM, EVM, and Move VM. This is the final version of how Lumio will function as described in the current documentation.
