/**
 * PythLazer EVM Contract Deployment and Management Script
 *
 * This script provides functionality to deploy PythLazer contracts and manage trusted signers
 * on EVM-compatible blockchains. It integrates with the DefaultStore system and supports
 * both deployment and contract management operations.
 *
 * FLAGS AND USAGE:
 *
 * 1. DEPLOYMENT FLAGS:
 *    --deploy                    Deploy the PythLazer contract (default: true)
 *    --verify                    Verify contract on block explorer after deployment
 *    --etherscan-api-key <key>   Required if --verify is true
 *
 * 2. TRUSTED SIGNER MANAGEMENT:
 *    --update-signer <address>   Address of the trusted signer to add/update
 *    --expires-at <timestamp>    Unix timestamp when the signer expires
 *
 * EXAMPLES:
 *
 * Deploy only:
 *   npx ts-node deploy_evm_lazer_contracts.ts --chain ethereum --private-key <key>
 *
 * Deploy with verification:
 *   npx ts-node deploy_evm_lazer_contracts.ts --chain ethereum --private-key <key> --verify --etherscan-api-key <key>
 *
 * Update trusted signer only (requires existing contract):
 *   npx ts-node deploy_evm_lazer_contracts.ts --chain ethereum --private-key <key> --deploy false --update-signer 0x123... --expires-at 1735689600
 *
 * Deploy and update trusted signer in one command:
 *   npx ts-node deploy_evm_lazer_contracts.ts --chain ethereum --private-key <key> --update-signer 0x123... --expires-at 1735689600
 *
 * NOTES:
 * - The --deploy flag defaults to true if no other flags are specified
 * - Both --update-signer and --expires-at must be provided together
 * - If updating trusted signer without deploying, an existing contract must be found
 * - The script automatically saves deployed contracts to the store and updates EvmLazerContracts.json
 * - All operations use the chain's RPC URL from the DefaultStore
