MagicBlock Ephemeral Rollups Guide

A comprehensive guide for building high-performance Solana applications with MagicBlock Ephemeral Rollups - enabling sub-10ms latency and gasless transactions.

Overview

MagicBlock Ephemeral Rollups (ER) are specialized SVM runtimes that enhance Solana with:

Sub-10ms latency (vs ~400ms on base Solana)

Gasless transactions for seamless UX

Full composability with existing Solana programs

Horizontal scaling via on-demand rollups

Core Flow

Initialize - Create accounts on Solana base layer

Delegate - Transfer account ownership to delegation program

Execute - Run fast operations on Ephemeral Rollup

Commit - Sync state back to base layer

Undelegate - Return ownership to your program

Prerequisites

# Required versions
Solana: 2.3.13
Rust: 1.85.0
Anchor: 0.32.1
Node: 24.10.0
Install Anchor (if needed)

cargo install --git https://github.com/coral-xyz/anchor anchor-cli

Quick Start

1. Add Dependencies (Cargo.toml)

[dependencies]
anchor-lang = "0.32.1"
ephemeral-rollups-sdk = { version = "0.6.5", features = ["anchor", "disable-realloc"] }

2. Program Setup (lib.rs)

```rust
use anchor_lang::prelude::*;
use ephemeral_rollups_sdk::anchor::{delegate_account, commit_accounts, ephemeral};
use ephemeral_rollups_sdk::cpi::DelegationProgram;
