Crab, the Ethereum-compatible smart contract platform on Kusama, accepted the Subview project into our grants program. Subview is a blockchain explorer for Crab Smart Chain data support and provides a comprehensive, easy-to-use interface for users to view, confirm, and inspect transactions.

The first version of Subview mainly launched core functions below::

  • Block: Provide detailed information about each block.
  • Transaction: Provides analysis of transactions.
  • Smart contract interaction: Users can read and verify Solidity smart contracts and access pre-existing contracts to fast-track development.
  • Token support: Support for ERC20 and ERC721 tokens.
  • Decoded views: Contract method calls and logs are decoded to provide additional information directly from the UI.

About Crab Network

Crab is a canary network with real economic value for Darwinia, and its positioning is similar to Polkadot’s Kusama Network. Crab Network has won the 22nd Kusama parachain slot! You can check Crab status through Polkadot{.js} , Subscan or Subview.

Crab provides smart contract solutions based on DVM (Darwinia Virtual Machine), which is compatible with the EVM (Ethereum Virtual Machine) paradigm at a low level. Therefore, it is easy for projects in the Ethereum ecosystem to migrate to the Crab Smart Chain. (Tips: DVM is built on Frontier with a fully EVM-compatible instruction set and an Ethereum RPC-like external interface.)

About Subview

Subview is a block explorer and analytics platform for Crab Smart Chain, users of Crab can use Subview to view and verify on-chain data. Additionally, as a long-term partnership, the Crab and Subview teams will work together to add advanced EVM functionality to the block explorer over time.
