# Set Machine NFT Block State

## `rwanft.setMachineNftBlockState(SetMachineNftBlockState)`

Set the block state of a Machine Issuer address or a Machine NFT contract address in the PeaqRwaNft contract. This sends a transaction signed by a Machine Regulator.

| -------------------------- | --------- | -------- | ----------------------------------------------------------------------------------------------- |
| **machineRegulatorSigner** | `Signer`  | Required | Machine Regulator signer authorized to update the block state. Must be connected to a provider. |
| **issuerOrContractNft**    | `string`  | Required | EOA address of a Machine Issuer or Machine NFT contract address.                                |
| **blocked**                | `boolean` | Required | `true` to block, `false` to unblock.                                                            |

### Usage

#### TypeScript

```TypeScript theme={"theme":{"light":"github-light-default","dark":"github-dark"}}
import 'dotenv/config';
import { RWA, Chain, type SDKInit } from '@peaq-network/rwa';
import { JsonRpcProvider, Wallet } from 'ethers';

async function main() {
  // 0. Create RWA instance and get provider
  const provider = new JsonRpcProvider(process.env.HTTPS_BASE_URL);
  const init: SDKInit = { chainId: Chain.AGUNG, provider: provider };
  const rwa_sdk = new RWA(init);

  // 1. Machine Regulator signer
  const machineRegulator = new Wallet(process.env.MACHINE_REGULATOR_PRIVATE_KEY!, provider);

  // 2. Target Machine Issuer or Machine NFT contract
  const target = process.env.MACHINE_ISSUER_PUBLIC_ADDRESS!;

  // 3. Block target
  const result = await rwa_sdk.rwanft.setMachineNftBlockState({
    machineRegulatorSigner: machineRegulator,
    issuerOrContractNft: target,
    blocked: true
  });
  console.log("Result", result);
}

main().catch((err) => {
  console.error(err);
  process.exit(1);
});
```

#### JavaScript

```js theme={"theme":{"light":"github-light-default","dark":"github-dark"}}
import 'dotenv/config';
import { RWA, Chain } from '@peaq-network/rwa';
import { JsonRpcProvider, Wallet } from 'ethers';

async function main() {
  // 0. Create RWA instance and get provider
  const provider = new JsonRpcProvider(process.env.HTTPS_BASE_URL);
  const rwa_sdk = new RWA({ chainId: Chain.AGUNG, provider });

  // 1. Machine Regulator signer
  const machineRegulator = new Wallet(process.env.MACHINE_REGULATOR_PRIVATE_KEY, provider);

  // 2. Target Machine Issuer or Machine NFT contract
  const target = process.env.MACHINE_ISSUER_PUBLIC_ADDRESS;

  // 3. Block target
  const result = await rwa_sdk.rwanft.setMachineNftBlockState({
    machineRegulatorSigner: machineRegulator,
    issuerOrContractNft: target,
    blocked: true
  });
  console.log("Result", result);
}

main().catch((err) => {
  console.error(err);
  process.exit(1);
});
```
