account: The recovered account you want to make a call on-behalf-of.
call: The call you want to make with the recovered account.

Namespace

api.tx.recovery.asRecovered

Type

function asRecovered(
  account: SeedPrimitivesSignatureAccountId20,
  call: Call
)

cancelRecovered

account: The recovered account you are able to call on-behalf-of.

Namespace

api.tx.recovery.cancelRecovered

Type

function cancelRecovered(
  account: SeedPrimitivesSignatureAccountId20
)

claimRecovery

Allow a successful rescuer to claim their recovered account. The dispatch origin for this call must be Signed and must be a “rescuer” who has successfully completed the account recovery process: collected threshold or more vouches, waited delay_period blocks since initiation. Parameters:

account: The lost account that you want to claim has been successfully recovered by you.

Namespace

api.tx.recovery.claimRecovery

Type

function claimRecovery(
  account: SeedPrimitivesSignatureAccountId20
)

closeRecovery

As the controller of a recoverable account, close an active recovery process for your account. Payment: By calling this function, the recoverable account will receive the recovery deposit RecoveryDeposit placed by the rescuer. The dispatch origin for this call must be Signed and must be a recoverable account with an active recovery process for it. Parameters:

rescuer: The account trying to rescue this recoverable account.

Namespace

api.tx.recovery.closeRecovery

Type

function closeRecovery(
  rescuer: SeedPrimitivesSignatureAccountId20
)

createRecovery

Create a recovery configuration for your account. This makes your account recoverable. Payment: ConfigDepositBase + FriendDepositFactor * #_of_friends balance will be reserved for storing the recovery configuration. This deposit is returned in full when the user calls remove_recovery. The dispatch origin for this call must be Signed. Parameters:

friends: A list of friends you trust to vouch for recovery attempts. Should be ordered and contain no duplicate values.
threshold: The number of friends that must vouch for a recovery attempt before the account can be recovered. Should be less than or equal to the length of the list of friends.
delay_period: The number of blocks after a recovery attempt is initialized that needs to pass before the account can be recovered.

Namespace

api.tx.recovery.createRecovery

Type

function createRecovery(
  friends: Vec<SeedPrimitivesSignatureAccountId20>,
  threshold: u16,
  delay_period: u32
)

initiateRecovery

Initiate the process for recovering a recoverable account. Payment: RecoveryDeposit balance will be reserved for initiating the recovery process. This deposit will always be repatriated to the account trying to be recovered. See close_recovery. The dispatch origin for this call must be Signed. Parameters:

account: The lost account that you want to recover. This account needs to be recoverable (i.e. have a recovery configuration).

Namespace

api.tx.recovery.initiateRecovery

Type

function initiateRecovery(
  account: SeedPrimitivesSignatureAccountId20

removeRecovery

Remove the recovery process for your account. Recovered accounts are still accessible.

Note: The user must make sure to call close_recovery on all active recovery attempts before calling this function else it will fail.

Payment: By calling this function the recoverable account will unreserve their recovery configuration deposit. (ConfigDepositBase + FriendDepositFactor * #_of_friends) The dispatch origin for this call must be Signed and must be a recoverable account (i.e. has a recovery configuration). Namespace

api.tx.recovery.removeRecovery

Type

function removeRecovery(

)

setRecovered

lost: The “lost account” to be recovered.
rescuer: The “rescuer account” which can call as the lost account.

Namespace

api.tx.recovery.setRecovered

Type

function setRecovered(
  lost: SeedPrimitivesSignatureAccountId20,
  rescuer: SeedPrimitivesSignatureAccountId20

vouchRecovery

Allow a “friend” of a recoverable account to vouch for an active recovery process for that account. The dispatch origin for this call must be Signed and must be a “friend” for the recoverable account. Parameters:

lost: The lost account that you want to recover.
rescuer: The account trying to rescue the lost account that you want to vouch for.

The combination of these two parameters must point to an active recovery process. Namespace

Constants

configDepositBase

The base amount of currency needed to reserve for creating a recovery configuration. This is held for an additional storage item whose value size is 2 + sizeof(BlockNumber, Balance) bytes. Namespace

api.consts.recovery.configDepositBase

Type

type configDepositBase = u128

friendDepositFactor

The amount of currency needed per additional user when creating a recovery configuration. This is held for adding sizeof(AccountId) bytes more into a pre-existing storage value. Namespace

api.consts.recovery.friendDepositFactor

Type

type friendDepositFactor = u128

maxFriends

The maximum amount of friends allowed in a recovery configuration.

NOTE: The threshold programmed in this Pallet uses u16, so it does not make sense to have a limit here greater than u16::MAX. But also, that is a lot more than you should probably set this value to anyway.

Namespace

api.consts.recovery.maxFriends

Type

type maxFriends = u32

recoveryDeposit

The base amount of currency needed to reserve for starting a recovery. This is primarily held for deterring malicious recovery attempts, and should have a value large enough that a bad actor would choose not to place this deposit. It also acts to fund additional storage item whose value size is sizeof(BlockNumber, Balance + T * AccountId) bytes. Where T is a configurable threshold. Namespace

api.consts.recovery.recoveryDeposit

Type

type recoveryDeposit = u128
