# Check deployer nonce and balance on Mainnet, Cronos, and Arbitrum (public RPCs by default).
# Use to diagnose "nonce too high" / "invalid nonce" and "insufficient funds" before retrying cW* deploy.
# Usage: ./scripts/deployment/check-deployer-nonce-and-balance.sh
# Requires: PRIVATE_KEY (repo root .env, smom-dbis-138/.env, or ~/.secure-secrets/private-keys.env via load-project-env).
# Optional: ETHEREUM_MAINNET_RPC, CRONOS_RPC_URL, ARBITRUM_MAINNET_RPC — if unset, uses public endpoints
# (override per chain with ETHEREUM_MAINNET_PUBLIC_RPC / CRONOS_MAINNET_PUBLIC_RPC / ARBITRUM_MAINNET_PUBLIC_RPC).
