Our review
Pros
  • EVM-equivalent execution supports standard Solidity contracts and Ethereum tooling.
  • Configurable settlement, data availability, fees, gas tokens and fault proofs.
  • Self-managed or managed operations with compliance controls for permissioned chains.
  • Reusable and custom modules support tailored blockchain logic
  • Native IBC enables cross-chain data and asset transfers
  • Enterprise modules support permissioned and consortium networks
Cons
  • Self-managed deployments put cloud and VPC operations on your team.
  • Fully managed infrastructure pricing is quote-based.
  • Its focus is Ethereum-compatible optimistic rollups, not general blockchain designs.
  • Self-hosted deployment puts node operations on your team
  • Custom chains require blockchain engineering and module development
  • Production use requires configuring and operating a network
