What you'll learn

  • β†’ How Optimistic Rollups and ZK Rollups work and their respective tradeoffs
  • β†’ Compare L1 vs L2 fees by transaction type and see the savings in action
  • β†’ Major L2 ecosystems: Arbitrum, Optimism, Base, zkSync, StarkNet

Bundle thousands of transactions and post them to L1 once. Split the cost N ways.

πŸ”
Inherited L1 Security

Final settlement on Ethereum. Assets can be withdrawn even if the sequencer is malicious.

EVM Compatible

Deploy existing dApps to L2 unchanged. Identical developer experience.
