# Manage collections and tokens

When you're connected with a wallet that owns a collection or holds a role in it, collection and token pages show a **creator menu**. It only lists actions your wallet is allowed to take.

## Collection settings

From a collection page:

| Action | Who can do it | What it does |
| --- | --- | --- |
| Create Token | Creator | Opens [`/create`](/create/tokens) with this collection selected. |
| Edit Collection Metadata | Owner | Edit the name, symbol, description, image, banner, external link and **URL Slug**. The metadata and the slug are saved together in one transaction. Clearing the slug removes it. |
| Edit Default Royalty | Owner | Change the royalty recipient and percentage used for every token that doesn't have its own. |
| Manage Roles | Owner | Grant or revoke roles. See [Roles](#roles). |
| Transfer Ownership | Owner | Start a transfer to another address or cancel a pending one. See [Ownership](#ownership). |
| Close Creation | Owner | Stop new tokens being added to the collection, permanently. See [Closing creation](#closing-creation). |
| Renounce Ownership | Owner | Leave the collection without an owner, permanently. See [Ownership](#ownership). |
| Accept Ownership | Pending owner | Accept a transfer started by the current owner. |

## Token settings

From a token page, or the **···** menu on its card in the collection page:

| Action | Who can do it | What it does |
| --- | --- | --- |
| Edit Metadata | Editor | Edit the name, description, image, media file (video, audio, 3D), external link, license, tags and attributes. Only available until the metadata is cemented. |
| Cement Metadata | Editor | Lock this token's metadata permanently. See [Cementing](#cementing). Not on [generative](/create/generative) tokens, whose render sets and cements their metadata. |
| Edit Royalty | Owner | Set a royalty for this token only, overriding the collection default. |
| Mint More | Minter | ERC-1155 only. Mint more editions to yourself, up to the max supply. |
| Burn | Holder | ERC-1155 only. Burn editions you own. |

## Roles

Every collection has an owner and three roles. When a collection is deployed, the owner's wallet gets all three.

| Role | Allows |
| --- | --- |
| **Creator** | Create new tokens in the collection. |
| **Minter** | Mint more editions of existing tokens. Drop contracts need this to run a [public mint](/create/selling#public-mint-erc-1155). |
| **Editor** | Edit token metadata and cement it. |

Only the owner can change collection metadata and royalties, manage roles, and upgrade the contract.

In **Manage Roles**, add an address, tick the roles it should have, and save. All the changes go out in one transaction. Anyone can renounce their own role at any time with `renounceRole`.

:::info
Opening a public mint grants **Minter** to the Modularium drop contract (`SimpleDrop` or `RecipeDrop`). Only you, as the collection owner, or Modularium operators can create drops for your tokens. Revoke the role to stop all minting through that contract.
:::

:::warning
A collection migrated from Forma also gives **Minter** to **Modularium Migration**, the contract that delivers migrated
tokens to their holders. Keep it: removing the role stops holders from claiming tokens they haven't claimed yet.

## Ownership

Transfers are two-step. The owner starts one with **Transfer Ownership**, and nothing changes until the new owner connects, opens the collection's creator menu (on the collection page or their profile's collections tab) and chooses **Accept Ownership**. Until then the owner can cancel it, or start a new one to replace it.

**Renounce Ownership** leaves the collection without an owner, permanently: nobody can change its metadata or royalties, manage roles, or upgrade it again. Existing roles keep working.

## Closing creation

**Close Creation** stops new tokens being added to the collection, by anyone, forever: nobody can create a token in it again, including you, a Creator or Modularium. It's how you prove a limit, such as "this collection is 100 pieces": anyone can check `creationClosed()` on the contract, and the collection page shows **Creation: Closed**.

Tokens already created aren't affected. ERC-721 tokens still in the pool can still be minted, and ERC-1155 tokens keep minting up to their max supply (an open edition with no max supply keeps minting). In a [generative](/create/generative) collection every mint is a new token, so closing creation stops minting.

Collections migrated from Forma are closed from the start, except Wanderer and Home-Studio, which still mint new pieces.

## Upgrades

Collections you create on Modularium can be upgraded to the latest Modularium contract, which brings fixes and new features. When a newer version is out, the owner sees **Upgrade available** next to the creator menu (on the collection page or their profile's collections tab). It lists what the new version changes; **UPGRADE** moves the collection to it in one transaction. Tokens, owners, metadata, royalties and roles stay as they are.

Upgrading is optional, and nobody else can upgrade your collection. Once upgrades are renounced (see below), it can never be upgraded again, and the offer no longer shows. If you've upgraded the collection to a contract of your own, Modularium doesn't offer to replace it.

## Cementing

Cementing makes something permanent. Nobody can undo it, including you and Modularium.

| What | How |
| --- | --- |
| Token metadata | **Cement Metadata** in the token's creator menu. |
| Collection metadata | `cementContractMetadata()` on the contract (not in the UI yet). |
| Royalties | `cementDefaultRoyalty()` / `cementTokenRoyalty(id)` on the contract (not in the UI yet). |
| Contract code | **Renounce Upgrades** in the collection's creator menu. |

## Drops

Your profile's **\[DROPS]** tab lists your open public mints. Click **CANCEL** to end one. See [Ending a mint](/create/selling#ending-a-mint).
