# DID Operations

<Warning>
  This concept has been absorbed into peaqOS. See [peaqID](/peaqos/concepts/peaqid) for the current identity model.
</Warning>

Using the instance created on the previous pages you are able to execute the peaq DID functionalities that allow for the creation of a DID Document.

## create(name, address, seed, customDocumentFields)

Enables the creation of a decentralized identity on-chain for your given entity.

## read(name, address, wssBaseUrl)

Allows a user to read a previously created DID from the chain.

| Parameter      | Type     | EVM      | Substrate | Description                                                                                                                                                                                               |
| -------------- | -------- | -------- | --------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **name**       | `string` | Required | Required  | Name of the DID stored.                                                                                                                                                                                   |
| **address**    | `string` | Required | Optional  | Address of the wallet that created the DID Document. Reading from an EVM tx requires an address to be explicitly set. If a seed has been set for Substrate, the address tied to that phrase will be used. |
| **wssBaseUrl** | `string` | Required | Optional  | WSS URL must be used to read DID Document. EVM must explicitly set WSS (Substrate has it stored during instance creation).                                                                                |

## update(name, address, seed, customDocumentFields)

Allows the owner of the DID Document to update a previously created one.  Uses the same parameters as createDid() function above for the Custom Document Fields.

| Parameter                | Type                   | EVM      | Substrate | Description                                                                                                                                              |
| ------------------------ | ---------------------- | -------- | --------- | -------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **name**                 | `string`               | Required | Required  | Name of the DID to be updated.                                                                                                                           |
| **address**              | `string`               | Required | Optional  | Wallet address that has the authority to update the DID Document. If Substrate seed at initialization, will default to the public address for that seed. |
| **wssBaseUrl**           | `string`               | Required | N/A       | WSS URL must be used to read a DID Document. Used to read the previous DID Document at that location when updating a DID Document.                       |
| **seed**                 | `string`               | N/A      | Optional  | If not set at instance creation, allows user to define who sends the Substrate Transactions.                                                             |
| **customDocumentFields** | `CustomDocumentFields` | Optional | Optional  | Used to update specific fields of the DID Document. Overwrites the previous DID Document so make sure you keep track of data previously stored.          |
