MagicBlock Development Skill

Pair with the solana-dev skill

Use this skill for MagicBlock-specific concerns: ER/PER, delegation, oracles, Session Keys, cranks, VRF, Magic Actions, eSPL, and private payments. For general Solana or Anchor work such as scaffolding, PDAs, account layouts, SPL tokens, clients, wallets, or LiteSVM/Mollusk testing, also load solana-dev.

Key Concepts

Ephemeral Rollups enable high-performance, low-latency transactions by locking a delegated account on the base layer while an ER clone continues to execute under the account's original program owner. They are useful for gaming, real-time apps, and fast transaction throughput.

Ephemeral Accounts are born, used, and closed only inside an ER. They are useful for temporary high-frequency state, but they never commit to Solana and therefore cannot be the only copy of durable ownership, balances, rewards, or settlement results.
