impl<T: Config> Pallet<T>

pub fn proxy(
 origin: OriginFor<T>,
 real: <<T as Config>::Lookup as StaticLookup>::Source,
 force_proxy_type: Option<T::ProxyType>,
 call: Box<<T as Config>::Call>
) -> DispatchResult

Dispatch the given call from an account that the sender is authorised for through add_proxy.

Removes any corresponding announcement(s).

The dispatch origin for this call must be Signed.

Parameters:

real: The account that the proxy will make a call on behalf of.
force_proxy_type: Specify the exact proxy type to be used and checked for this call.
call: The call to be made by the real account.

Weight is a function of the number of proxies the user has (P).

pub fn add_proxy(
 origin: OriginFor<T>,
 delegate: <<T as Config>::Lookup as StaticLookup>::Source,
 proxy_type: T::ProxyType,
 delay: T::BlockNumber
) -> DispatchResult

Register a proxy account for the sender that is able to make calls on its behalf.

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.

Weight is a function of the number of proxies the user has (P).

pub fn remove_proxy(
 origin: OriginFor<T>,
 delegate: <<T as Config>::Lookup as StaticLookup>::Source,
 proxy_type: T::ProxyType,
 delay: T::BlockNumber
) -> DispatchResult

Unregister a proxy account for the sender.

The dispatch origin for this call must be Signed.

Parameters:

proxy: The account that the caller would like to remove as a proxy.
proxy_type: The permissions currently enabled for the removed proxy account.

Weight is a function of the number of proxies the user has (P).

pub fn remove_proxies(origin: OriginFor<T>) -> DispatchResult

Unregister all proxy accounts for the sender.

The dispatch origin for this call must be Signed.

WARNING: This may be called on accounts created by anonymous, however if done, then the unreserved fees will be inaccessible. All access to this account will be lost.

Weight is a function of the number of proxies the user has (P).

pub fn anonymous(
 origin: OriginFor<T>,
 proxy_type: T::ProxyType,
 delay: T::BlockNumber,
 index: u16
) -> DispatchResult

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.

Weight is a function of the number of proxies the user has (P).

pub fn kill_anonymous(
 origin: OriginFor<T>,
 spawner: <<T as Config>::Lookup as StaticLookup>::Source,
 proxy_type: T::ProxyType,
 index: u16,
 height: T::BlockNumber,
 ext_index: u32
) -> DispatchResult

Removes a previously spawned anonymous 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 anonymous with corresponding parameters.

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

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

Weight is a function of the number of proxies the user has (P).

pub fn announce(
 origin: OriginFor<T>,
 real: <<T as Config>::Lookup as StaticLookup>::Source,
 call_hash: <<T as Config>::CallHasher as Hash>::Output
) -> DispatchResult

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.

Weight is a function of:

A: the number of announcements made.
P: the number of proxies the user has.

May be called by a proxy account to remove a call they previously announced and return the deposit.

The dispatch origin for this call must be Signed.

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.

Weight is a function of:

A: the number of announcements made.
P: the number of proxies the user has.

May be called by a target (proxied) account to remove a call that one of their delegates (delegate) has announced they want to execute. The deposit is returned.

The dispatch origin for this call must be Signed.

Parameters:

delegate: The account that previously announced the call.
call_hash: The hash of the call to be made.

Weight is a function of:

A: the number of announcements made.
P: the number of proxies the user has.
