1_Verify.ts

// This script can be run against a public or forked networks.
// Export following environment variables:
// - NODE_URL_1: Mainnet node URL (not required when using localhost for a forked network).
// - NODE_URL_137: Public or forked Polygon node URL.
// - NODE_URL_10: Public or forked Optimism node URL.
// - NODE_URL_42161: Public or forked Arbitrum node URL.
// - NODE_URL_8453: Public or forked Base node URL.
// - NODE_URL_81457: Public or forked Blast node URL.
// - IDENTIFIER: Identifier to remove.
// Then run the script with:
//   yarn hardhat run packages/scripts/src/admin-proposals/remove-identifier/1_Verify.ts --network <network>
// Note: use localhost for the forked network, for L1 mainnet need to export NODE_URL_1 environment variable.
