eth_chainId
Returns the chain ID of the network the node is connected to. The chain ID is used in transaction signing to prevent replay attacks across different networks.

Notes
- PulseChain mainnet returns
0x171(369 in decimal). - The chain ID was introduced in EIP-155 to prevent transaction replay attacks between networks.
- Wallets and libraries use this value to ensure transactions are signed for the correct network.
eth_estimateGas
Estimates the amount of gas required to execute a transaction. The transaction is not actually sent to the network. The estimate may be higher than the actual gas used because of EVM mechanics and nod
eth_call
Executes a read-only call against a contract without creating a transaction on the blockchain. This is the primary method for reading data from smart contracts, such as querying ERC20 token balances,
