parseErc1167(bytecode: Uint8Array): Uint8Array | null

Extracts the implementation address from ERC-1167 minimal proxy bytecode. Parameters:
  • bytecode: Uint8Array - Proxy bytecode (45 or 55 bytes)
Returns: Uint8Array | null - 20-byte implementation address or null if invalid Example: 
import { parseErc1167 } from '@tevm/voltaire/Proxy';
import { Address } from '@tevm/voltaire/Address';

// Get deployed code
const code = await eth_getCode('0xCloneAddress...');
const codeBytes = Buffer.from(code.slice(2), 'hex');

// Extract implementation
const implementation = parseErc1167(codeBytes);

if (implementation) {
  console.log('Implementation:', implementation.toHex());
} else {
  console.log('Not a valid ERC-1167 proxy');
}
