Unlink an Account From a KILT DID

Similar to the way a new account to DID link is created, removing a link can happen in one of three ways:

1. The DID owner submits a transaction indicating which account to unlink:

Typescript

import * as Kilt from '@kiltprotocol/sdk-js'

export async function unlinkAccountFromDid(
  did: Kilt.DidUri,
  submitterAccount: Kilt.KiltKeyringPair,
  linkedAccountAddress: Kilt.KiltAddress,
  signCallback: Kilt.SignExtrinsicCallback
): Promise<void> {
  const api = Kilt.ConfigService.get('api')

  // The DID owner removes the link between itself and the specified account.
  const accountUnlinkTx = api.tx.didLookup.removeAccountAssociation({
    AccountId32: linkedAccountAddress
  })
  const authorizedAccountUnlinkTx = await Kilt.Did.authorizeTx(
    did,
    accountUnlinkTx,
    signCallback,
    submitterAccount.address
  )

  await Kilt.Blockchain.signAndSubmitTx(
    authorizedAccountUnlinkTx,
    submitterAccount
  )
}

2. The linked account submits a transaction indicating that the link with the DID should be removed:

Typescript

import * as Kilt from '@kiltprotocol/sdk-js'

export async function unlinkDidFromAccount(
  linkOwnerAccount: Kilt.KeyringPair
): Promise<void> {
  const api = Kilt.ConfigService.get('api')

  // The tx does not need to be authorized by a DID, but the submitter account removes its own link.
  const accountUnlinkTx = api.tx.didLookup.removeSenderAssociation()

  await Kilt.Blockchain.signAndSubmitTx(accountUnlinkTx, linkOwnerAccount)
}

3. The deposit payer submits a transaction indicating that they want to reclaim their deposit, which in turn removes the existing link between the specified account and DID:

Typescript

import * as Kilt from '@kiltprotocol/sdk-js'

export async function reclaimLinkDeposit(
  submitterAddress: Kilt.KeyringPair,
  linkedAccountAddress: Kilt.KiltAddress
): Promise<void> {
  const api = Kilt.ConfigService.get('api')

  // The tx does not need to be authorized by a DID, but the deposit payer's account claims the deposit and removes the link.
  const accountUnlinkTx = api.tx.didLookup.reclaimDeposit({
    AccountId32: linkedAccountAddress
  })

  await Kilt.Blockchain.signAndSubmitTx(accountUnlinkTx, submitterAddress)
}
