Module proxy 

Proxy Pattern Detection

Detects common Ethereum proxy patterns by analyzing bytecode, storage slots, and source code metadata.

Supported Patterns

• EIP-1967 - Transparent Proxy (implementation slot: 0x360894...)
• EIP-1822 - UUPS (Universal Upgradeable Proxy Standard)
• Transparent Proxy - OpenZeppelin TransparentUpgradeableProxy
• Beacon Proxy - EIP-1967 beacon slot
• Minimal Proxy (EIP-1167) - Clone factory pattern (bytecode detection)
• Diamond (EIP-2535) - Multi-facet proxy

Detection Methods

1. Etherscan metadata - Proxy and Implementation fields from getsourcecode
2. Storage slot reads - Check well-known EIP-1967 slots
3. Bytecode patterns - EIP-1167 minimal proxy prefix/suffix

Structs
