// Pre-signed contract deployment example
//
// Real on-chain deployment only happens when constructor_args contains
// "raw_transaction" or "signed_tx" with a hex string from your build tooling
// (Foundry, Hardhat, etc.). See: docs/guides/PRESIGNED_DEPLOYMENT_GUIDE.md
//
// Without that key, chain::deploy returns a mock address (for demos only).

    // Deploy using a pre-signed tx hex (e.g. from CI or a deploy service).
    // The hex is built and signed outside DAL (Foundry/Hardhat/Node).

        let address = chain::deploy(
            chain_id,

        return chain::deploy(chain_id, contract_name, { "signed_tx": signed_tx_hex });
    }

    // Demo path: no raw tx → mock address only (no real deployment).
    // Use for testing script shape; use deploy_with_presigned for real deploys.

        return address;

// Example: multi-chain deploy when you have one signed tx per chain.
// In practice, raw_tx_for_chain_1 and raw_tx_for_chain_137 would come from
// env, a secure API, or a CI artifact — never hardcode a signed tx.
