MagicBlock ephemeral rollups execute delegated trading state. Solana’s base layer holds token custody and processes the actual swaps, payouts and withdrawals.

Deposit → make trading funds available → open → close or liquidate → commit/release required state → execute settlement → issue ownership or service the FIFO claim. Some phases complete separately, so the UI shows progress instead of pretending every step is instantaneous.
