Proxy

Calls

addProxy

The dispatch origin for this call must be Signed.

Parameters:

proxy: The account that the caller would like to make a proxy.
proxy_type: The permissions allowed for this proxy account.
delay: The announcement period required of the initial proxy. Will generally be zero.

Namespace

api.tx.proxy.addProxy

Type

function addProxy(
  delegate: SeedPrimitivesSignatureAccountId20,
  proxy_type: SeedRuntimeImplsProxyType,
  delay: u32
)

announce

Publish the hash of a proxy-call that will be made in the future.

This must be called some number of blocks before the corresponding proxy is attempted if the delay associated with the proxy relationship is greater than zero.

No more than MaxPending announcements may be made at any one time.

This will take a deposit of AnnouncementDepositFactor as well as AnnouncementDepositBase if there are no other pending announcements.

The dispatch origin for this call must be Signed and a proxy of real.

Parameters:

real: The account that the proxy will make a call on behalf of.
call_hash: The hash of the call to be made by the real account.

Namespace

api.tx.proxy.announce

Type

function announce(
  real: SeedPrimitivesSignatureAccountId20,
  call_hash: H256
)

createPure

Spawn a fresh new account that is guaranteed to be otherwise inaccessible, and initialize it with a proxy of proxy_type for origin sender.

Requires a Signed origin.

proxy_type: The type of the proxy that the sender will be registered as over the new account. This will almost always be the most permissive ProxyType possible to allow for maximum flexibility.
index: A disambiguation index, in case this is called multiple times in the same transaction (e.g. with utility::batch). Unless you're using batch you probably just want to use 0.
delay: The announcement period required of the initial proxy. Will generally be zero.

Fails with Duplicate if this has already been called in this transaction, from the same sender, with the same parameters.

Fails if there are insufficient funds to pay for deposit.

Namespace

api.tx.proxy.createPure

Type

function createPure(
  proxy_type: SeedRuntimeImplsProxyType,
  delay: u32,
  index: u16
)

killPure

Removes a previously spawned pure proxy.

WARNING: All access to this account will be lost. Any funds held in it will be inaccessible.

Requires a Signed origin, and the sender account must have been created by a call to pure with corresponding parameters.

spawner: The account that originally called pure to create this account.
index: The disambiguation index originally passed to pure. Probably 0.
proxy_type: The proxy type originally passed to pure.
height: The height of the chain when the call to pure was processed.
ext_index: The extrinsic index in which the call to pure was processed.

Fails with NoPermission in case the caller is not a previously created pure account whose pure call has corresponding parameters.

api.tx.proxy.killPure

Type

function killPure(
  spawner: SeedPrimitivesSignatureAccountId20,
  proxy_type: SeedRuntimeImplsProxyType,

)

Namespace

api.consts.proxy.announcementDepositBase

Type

type announcementDepositBase = u128

The amount of currency needed per announcement made.

This is held for adding an AccountId, Hash and BlockNumber (typically 68 bytes) into a pre-existing storage value.

Type

type announcementDepositFactor = u128

maxPending

The maximum amount of time-delayed announcements that are allowed to be pending.

The maximum amount of proxies allowed for a single account.

Namespace

api.consts.proxy.maxProxies
