Solana Ephemeral Rollups Counter Program

This is a minimal counter program built on Solana using Anchor and MagicBlock's Ephemeral Rollups (ER) runtime.
It demonstrates how to delegate program control to ER, perform high-frequency updates off-chain, and commit or undelegate the state back to Solana's L1.

Features

• Anchor-based Solana smart contract
• Counter logic using a deterministic PDA
• Delegation to MagicBlock's ER
• Commit & undelegate support
• ER macros like #[ephemeral], #[delegate], #[commit] in action

Quick Start

1. Clone the repository

git clone https://github.com/kirtiraj22/magicblock-counter
cd magicblock-counter

2. Install dependencies

npm install

3. Build the program

anchor build

4. Deploy to localnet
