Defines the available Ethereum JSON-RPC methods and their parameters.

This module maintains a comprehensive mapping of supported Ethereum JSON-RPC methods, their parameter requirements, and whether they accept a default block parameter.

Method Structure

Each method is defined as a tuple with three elements:

• RPC method name (atom)
• List of required parameters (list of atoms)
• Boolean indicating if method accepts a block parameter (boolean)

Method Categories

Methods are organized into the following namespaces:

Web3 Namespace

• Basic web3 operations (clientVersion, sha3)

Net Namespace

• Network status and information
• Peer connections
• Network version

Eth Namespace

• Basic chain information
• Block operations
• Transaction operations
• Account operations
• Filter management
• Contract interaction

Parameter Types

Common parameter types include:

• :address - 20-byte Ethereum address (hex string)
• :block_hash - 32-byte block hash (hex string)
• :block_number - Block number or tag ("latest", "earliest", "pending")
• :transaction_hash - 32-byte transaction hash (hex string)
• :data - Arbitrary hex data
• :filter - Filter options object
• :transaction - Transaction object
• :position - Storage position (hex string)

Usage

This module is primarily used internally by the Provider module to:

• Generate method implementations
• Validate method parameters
• Handle default block parameters

To get the complete list of available methods:

iex> Exth.Provider.Methods.methods()
%{
  client_version: {:web3_clientVersion, [], false},
  # ... other methods
