Developer Experience

Docs

  • Shipped a comprehensive revamp of the Solana documentation with improved navigation, updated content, and new developer tools.
  • Completely refreshed the Solana Quickstart Guide 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working code repositories that walk developers through building live, functioning sample apps—replacing the previous outdated guides.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 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.
