Chain id

Description

In the VeChain EVM, the block.chainid opcode returns the 32-byte genesis block ID, which represents a significantly larger value than the typical chainId used in other EVM-compatible networks.

This difference will cause the eip712Domain hex values of the contract and the local computation in the EIP712 test cases to be different.

Therefore, we modified the test code. When calculating the eip712Domain locally, instead of directly using the value returned by the eth_chainId RPC interface, we used eth_getBlockByNumber to obtain the ID of the genesis block to ensure that the hex value of eip712Domain is the same.
