System::Call

Variant 117 v411

frame_system::pallet::Call

Contains a variant per dispatchable extrinsic that this pallet has.

About This Type

Call enum for the Call pallet.

Contains all dispatchable functions (extrinsics) for the Call pallet. Each variant represents a different callable function with its parameters.

Variants (11)

Index	Name	Fields	Docs
0	remark	remark: Vec<u8>	Make some on-chain remark. Can be executed by every `origin`.
1	set_heap_pages	pages: u64	Set the number of pages in the WebAssembly environment's heap.
2	set_code	code: Vec<u8>	Set the new runtime code.
3	set_code_without_checks	code: Vec<u8>	Set the new runtime code without doing any checks of the given `code`. Note that runtime upgrades will not run if this is called with a not-increasing spec version!
4	set_storage	items: Vec<(Vec<u8>, Vec<u8>)>	Set some items of storage.
5	kill_storage	keys: Vec<Vec<u8>>	Kill some items from storage.
6	kill_prefix	prefix: Vec<u8> subkeys: u32	Kill all storage items with a key that starts with the given prefix. NOTE: We rely on the Root origin to provide us the number of subkeys under the prefix we are removing to accurately calculate the weight of this function.
7	remark_with_event	remark: Vec<u8>	Make some on-chain remark and emit event.
9	authorize_upgrade	code_hash: H256	Authorize an upgrade to a given `code_hash` for the runtime. The runtime can be supplied later. This call requires Root origin.
10	authorize_upgrade_without_checks	code_hash: H256	Authorize an upgrade to a given `code_hash` for the runtime. The runtime can be supplied later. WARNING: This authorizes an upgrade that will take place without any safety checks, for example that the spec name remains the same and that the version number increases. Not recommended for normal use. Use `authorize_upgrade` instead. This call requires Root origin.
11	apply_authorized_upgrade	code: Vec<u8>	Provide the preimage (runtime binary) `code` for an upgrade that has been authorized. If the authorization required a version check, this call will ensure the spec name remains unchanged and that the spec version has increased. Depending on the runtime's `OnSetCode` configuration, this function may directly apply the new `code` in the same block or attempt to schedule the upgrade. All origins are allowed.

Examples

remark = remark(remark)

0x00<field0>

00 Variant index 0 = remark

field 0 remark: Vec<u8>

set_heap_pages = set_heap_pages(pages)

0x01<field0>

01 Variant index 1 = set_heap_pages

field 0 pages: u64

set_code = set_code(code)

0x02<field0>

02 Variant index 2 = set_code

field 0 code: Vec<u8>

Code Examples

import { TypeRegistry } from "@polkadot/types";

const registry = new TypeRegistry();

// Encode System::Call — variant "remark"
const value = registry.createType("System::Call", { remark: { remark: 0 } });
console.log("Hex:", value.toHex());
