## Developer Experience

**Docs**

* Shipped a comprehensive revamp of the [Solana documentation](https://www.alchemy.com/docs/solana) with improved navigation, updated content, and new developer tools.
* Completely refreshed the [Solana Quickstart Guide](https://www.alchemy.com/docs/solana) with a streamlined onboarding flow, tested working scripts for sending requests, creating and funding wallets, and a full breakdown of all supported Solana methods organized by category.
* Published two brand-new tutorials with fresh, working code repositories that walk developers through building live, functioning sample apps—replacing the previous outdated guides.
* Introduced a new [Compute Unit (CU) Calculator](https://solana-demo-sigma.vercel.app/) to help developers understand how many CUs their integrated methods require and plan their usage accordingly.
* Updated the Solana FAQ with a methods-by-category breakdown, making it easier to discover what's supported and what you can build with each method.

## Rollups

* Launched Mythos Mainnet for Mythical Games, our first OP Stack Layer 3 rollup. Mythical Games will use this rollup to power in-game NFT items and their marketplace for popular mobile games like NFL Rivals.
* Shipped support for the Fusaka activation on Ethereum Mainnet, enabling rollups with Ethereum Mainnet as the parent chain to continue sequencing after the network upgrade.
