Overall Activity in the Past Quarter

  • Solang sema module had a security audit from trail of bits. No major issues were found.
  • For Solana, we have a new annotation syntax for specifying seed, bump, payer, and size for new contract. The syntax was inspired by Java annotations.
  • Math overflow now works for all integer types and is always enabled
  • For Substrate, chain extensions can now be used.
  • The Ethereum Solidity parser and semantic tests are now being run during tests. There are still failures, however we have made numerous improvements.
  • New contributors showing up in discord and are creating pull requests. The good first issue label is working well.

Current Plans

  • Do everything to support and attract Solidity developers on Solana and Substrate
  • Improve the developer experience for Solidity
  • Maintain compatibility with the latest Solidity version
  • More security audits
