  • Phase 1 & 2 simulation
  • Truffle like test tool to run wasm contracts within an EE (eth1 EE or eth2 EE)
  • Runtime environment to plug into phase 1 clients
  • Authenticated multi-proof backend (clients to generate, merge and manage multiproofs)
  • Wasm centric smart contract languages with cross shard tooling
