dispatchRemoveDelegateToChain

dispatchRemoveDelegateToChain(registryUri, removeAuthorizationUri, namespaceAuthorizationUri, authorizationUri, authorAccount): Promise<object>

Removes a delegate from a registry on the chain.

This method is used to remove a delegate’s authorization from a given registry. It checks whether the registry and the provided authorization exist on-chain, constructs the required parameters, and dispatches the extrinsic to the blockchain for execution.

Parameters

• registryUri: `registry:cord:${string}`

The URI of the registry from which the delegate will be removed.

• removeAuthorizationUri: `registryauth:cord:${string}`

The URI of the authorization to be removed (i.e., the delegate’s authorization).

• namespaceAuthorizationUri: `namespaceauth:cord:${string}`

The URI of the namespace authorization associated with the registry.

• authorizationUri: `registryauth:cord:${string}`

The URI of the authorization of the account performing the removal (the caller’s authorization).

• authorAccount: CordKeyringPair

The account key pair of the entity removing the delegate, used for signing the transaction.

Returns

Promise<object>

An object containing the URIs related to the registry and authorizations. - uri: The URI of the registry. - removeAuthorizationUri: The authorization URI of the delegate being removed. - namespaceAuthorizationUri: The authorization URI of the namespace. - authorizationUri: The authorization URI of the signer performing the removal.

authorizationUri

authorizationUri: RegistryAuthorizationUri

removeAuthorizationUri

removeAuthorizationUri: RegistryAuthorizationUri

uri

uri: RegistryUri

Async

Function

Throws

• If the registry URI does not exist on-chain.
• If the authorization URI of the signer does not exist on-chain.
• If an error occurs while dispatching the transaction to the chain.

Example

const registryUri = 'did:cord:registry:3abc...';
const removeAuthorizationUri = 'did:cord:auth:3xyz...';
const namespaceAuthorizationUri = 'did:cord:auth:238342...';
const authorizationUri = 'did:cord:auth:3signer...';
const authorAccount = keyring.addFromUri('//Alice');

dispatchRemoveDelegateToChain(registryUri, removeAuthorizationUri, authorizationUri, authorAccount)
  .then(result => {
    console.log('Delegate removed:', result);
  })
  .catch(error => {
    console.error('Error removing delegate:', error);
  });

Description

The function first verifies the existence of the registry and the signer’s authorization on the blockchain. It then encodes the provided URIs into identifiers and submits a signed transaction to remove the delegate from the registry. If the removal is successful, it returns an object with the registry URI and relevant authorization URIs.
