About ValueChain EVM

The EVM syschain manages the overall system state of ValueChain and provides full support for all EVM-compatible dApps. Beyond that, it also acts as the unified account system for other appchains, ensuring that every appchain remains interoperable with the broader EVM ecosystem. Each appchain, in turn, maintains the transactions and state of its dedicated application, enabling deterministic and high-performance execution. SOSO is the native gas token on the EVM syschain.

Note that there are currently no official frontend components of the EVM. Users can build their own frontends or port over existing EVM applications. All interaction with the EVM happens through the JSON-RPC. For example, users can add the chain to their wallets by entering the RPC URL and chain ID.

The EVM syschain uses the Pectra hardfork without blobs. In particular, EIP-1559 is enabled on the EVM syschain. Unlike standard implementation of EIP-1559, the base fees are not burned and instead sent together with priority fees to block builder.

On both mainnet and testnet, SOSO on the EVM syschain has 18 decimals. A few differences between testnet and mainnet are highlighted below:
