## Deployment

Deploy contracts with zero code via [Hub](https://hub.immutable.com) or programmatically:

```bash theme={null}
npm install @imtbl/contracts
```

See individual contract pages for implementation examples.

## Operator Allowlist

Controls which contracts can transfer your NFTs. For details, see [Operator Allowlist](/docs/products/asset-contracts/operator-allowlist).

<Info>
  [Immutable's Orderbook](/docs/products/orderbook/overview) and major marketplaces are pre-approved.
</Info>

## Royalties

All contracts support EIP-2981 royalties:

* Set percentage at deployment (e.g., 5% = 500 basis points)
* Enforced on [Immutable's Orderbook](/docs/products/orderbook/overview)
* Automatic payment on secondary sales

## Verification

Get your collections verified to build trust with players and ecosystem partners.

### Verification Badge

Verified collections display a green checkmark across Immutable's ecosystem, indicating legitimacy to the community.

Link contracts to [Hub](https://hub.immutable.com) and request verification.

Verified collections display a green checkmark on marketplaces and ecosystem apps.

### Inactive Collections

Mark test or abandoned collections as **Inactive** in Hub to:

* Delist from marketplace search results
* Signal to players not to transact with these assets
* Keep your game's collection list clean

## Trading Rewards

Register your collections with Immutable's [Trading Rewards](https://www.digitalworldsnfts.com/trading-rewards) program to incentivize secondary market activity.

<Info>
  Collections must have royalties set to at least **0.5%** to be eligible. Contact your Immutable account manager to register.
