scheduleGrandpaChange(next_authorities: AuthorityList, in_blocks: u32, forced: Option<BlockNumberFor<T>>)

• interface: api.tx.adminUtils.scheduleGrandpaChange

• summary: A public interface for pallet_grandpa::Pallet::schedule_grandpa_change.

  Schedule a change in the authorities.

  The change will be applied at the end of execution of the block in_blocks after the current block. This value may be 0, in which case the change is applied at the end of the current block.

  If the forced parameter is defined, this indicates that the current set has been synchronously determined to be offline and that after in_blocks the given change should be applied. The given block number indicates the median last finalized block number and it should be used as the canon block when starting the new grandpa voter.

  No change should be signaled while any change is pending. Returns an error if a change is already pending.

call(dest: MultiAddress, value: u128, gas_limit: Weight, storage_deposit_limit: Option<<BalanceOf<T> as codec::HasCompact>::Type>, data: Vec<u8>)

• interface: api.tx.contracts.call

• summary: Makes a call to an account, optionally transferring some balance.

  Parameters:

  • dest: Address of the contract to call.

  • value: The balance to transfer from the origin to dest.

  • gas_limit: The gas limit enforced when executing the constructor.

  • storage_deposit_limit: The maximum amount of balance that can be charged from the caller to pay for the storage consumed.

  • data: The input data to pass to the contract.

  • If the account is a smart-contract account, the associated code will be executed and any value will be transferred.

  • If the account is a regular account, any value will be transferred.

  • If no account exists and the call value is not less than existential_deposit, a regular account will be created and any value will be transferred.

callOldWeight(dest: MultiAddress, value: u128, gas_limit: OldWeight, storage_deposit_limit: Option<<BalanceOf<T> as codec::HasCompact>::Type>, data: Vec<u8>)

• interface: api.tx.contracts.callOldWeight

• interface: api.tx.contracts.instantiate

• summary: Instantiates a contract from a previously deployed wasm binary.

  This function is identical to [Self::instantiate_with_code] but without the code deployment step. Instead, the code_hash of an on-chain deployed wasm binary must be supplied.

instantiateOldWeight(value: u128, gas_limit: OldWeight, storage_deposit_limit: Option<<BalanceOf<T> as codec::HasCompact>::Type>, code_hash: CodeHash, data: Vec<u8>, salt: Vec<u8>)

• interface: api.tx.contracts.instantiateOldWeight
• summary: Deprecated version if [Self::instantiate] for use in an in-storage Call.

instantiateWithCode(value: u128, gas_limit: Weight, storage_deposit_limit: Option<<BalanceOf<T> as codec::HasCompact>::Type>, code: Vec<u8>, data: Vec<u8>, salt: Vec<u8>)

• interface: api.tx.contracts.instantiateWithCode

• summary: Instantiates a new contract from the supplied code optionally transferring some balance.

  This dispatchable has the same effect as calling [Self::upload_code] + [Self::instantiate]. Bundling them together provides efficiency gains. Please also check the documentation of [Self::upload_code].

  Parameters:

  • value: The balance to transfer from the origin to the newly created contract.
  • gas_limit: The gas limit enforced when executing the constructor.
  • storage_deposit_limit: The maximum amount of balance that can be charged/reserved from the caller to pay for the storage consumed.
  • code: The contract code to deploy in raw bytes.
  • data: The input data to pass to the contract constructor.
  • salt: Used for the address derivation. See [Pallet::contract_address].

  Instantiation is executed as follows:

  • The supplied code is deployed, and a code_hash is created for that code.
  • If the code_hash already exists on the chain the underlying code will be shared.
  • The destination address is computed based on the sender, code_hash and the salt.
  • The smart-contract account is created at the computed address.
  • The value is transferred to the new account.
  • The deploy function is executed in the context of the newly-created account.

instantiateWithCodeOldWeight(value: u128, gas_limit: OldWeight, storage_deposit_limit: Option<<BalanceOf<T> as codec::HasCompact>::Type>, code: Vec<u8>, data: Vec<u8>, salt: Vec<u8>)

• interface: api.tx.contracts.instantiateWithCodeOldWeight
• summary: Deprecated version if [Self::instantiate_with_code] for use in an in-storage Call.

migrate(weight_limit: Weight)

• interface: api.tx.contracts.migrate
• summary: When a migration is in progress, this dispatchable can be used to run migration steps. Calls that contribute to advancing the migration have their fees waived, as it's helpful for the chain. Note that while the migration is in progress, the pallet will also leverage the on_idle hooks to run migration steps.

removeCode(code_hash: CodeHash)

• interface: api.tx.contracts.removeCode

• summary: Remove the code stored under code_hash and refund the deposit to its owner.

  A code can only be removed by its original uploader (its owner) and only if it is not used by any contract.

setCode(dest: MultiAddress, code_hash: CodeHash)

• interface: api.tx.contracts.setCode

• summary: Privileged function that changes the code of an existing contract.

  This takes care of updating refcounts and all other necessary operations. Returns an error if either the code_hash or dest do not exist.

  Note:

  This does not change the address of the contract in question. This means that the contract address is no longer derived from its code hash after calling this dispatchable.

uploadCode(code: Vec<u8>, storage_deposit_limit: Option<<BalanceOf<T> as codec::HasCompact>::Type>, determinism: Determinism)

• interface: api.tx.contracts.uploadCode

• summary: Upload new code without instantiating a contract from it.

  If the code does not already exist a deposit is reserved from the caller and unreserved only when [Self::remove_code] is called. The size of the reserve depends on the size of the supplied code.

  If the code already exists in storage it will still return Ok and upgrades the in storage version to the current InstructionWeights::version.

  • determinism: If this is set to any other value but [Determinism::Enforced] then the only way to use this code is to delegate call into it from an offchain execution. Set to [Determinism::Enforced] if in doubt.

  Note:

  Anyone can instantiate a contract from any uploaded code and thus prevent its removal. To avoid this situation a constructor could employ access control so that it can only be instantiated by permissioned entities. The same is true when uploading through [Self::instantiate_with_code].

  Use [Determinism::Relaxed] exclusively for non-deterministic code. If the uploaded code is deterministic, specifying [Determinism::Relaxed] will be disregarded and result in higher gas costs.

grandpa

noteStalled(delay: u32, best_finalized_block_number: u32)

• interface: api.tx.grandpa.noteStalled

• summary: Note that the current authority set of the GRANDPA finality gadget has stalled.

  This will trigger a forced authority set change at the beginning of the next session, to be enacted delay blocks after that. The delay should be high enough to safely assume that the block signalling the forced change will not be re-orged e.g. 1000 blocks. The block production rate (which may be slowed down because of finality lagging) should be taken into account when choosing the delay. The GRANDPA voters based on the new authority will start voting on top of best_finalized_block_number for new finalized blocks. best_finalized_block_number should be the highest of the latest finalized block of all validators of the new authority set.

  Only callable by root.

  Filter from origin are passed along. The call will be dispatched with an origin which use the same filter as the origin of this call.

  NOTE: If you need to ensure that any account-based filtering is not honored (i.e. because you expect proxy to have been used prior in the call stack and you do not want the call restrictions to apply to any sub-accounts), then use as_multi_threshold_1 in the Multisig pallet instead.

  NOTE: Prior to version *12, this was called as_limited_sub.

  The dispatch origin for this call must be Signed.

batch(calls: Vec<RuntimeCall>)

• interface: api.tx.utility.batch

  Complexity:

  • O(C) where C is the number of calls to be batched.

  This will return Ok in all circumstances. To determine the success of the batch, an event is deposited. If a call failed and the batch was interrupted, then the BatchInterrupted event is deposited, along with the number of successful calls made and the error of the failed call. If all were successful, then the BatchCompleted event is deposited.

batchAll(calls: Vec<RuntimeCall>)

ifElse(main: Box<RuntimeCall>, fallback: Box<RuntimeCall>)

• interface: api.tx.utility.ifElse

• summary: Dispatch a fallback call in the event the main call fails to execute. May be called from any origin except None.

  This function first attempts to dispatch the main call. If the main call fails, the fallback is attemted. if the fallback is successfully dispatched, the weights of both calls are accumulated and an event containing the main call error is deposited.

  In the event of a fallback failure the whole call fails with the weights returned.

  • main: The main call to be dispatched. This is the primary action to execute.
  • fallback: The fallback call to be dispatched in case the main call fails.

  Dispatch Logic:

  • If the origin is root, both the main and fallback calls are executed without applying any origin filters.
  • If the origin is not root, the origin filter is applied to both the main and fallback calls.

  Use Case:

  • Some use cases might involve submitting a batch type call in either main, fallback or both.

withWeight(call: Box<RuntimeCall>, weight: Weight)

• interface: api.tx.utility.withWeight

• summary: Dispatch a function call with a specified weight.

  This function does not check the weight of the call, and instead allows the Root origin to specify the weight of the call.
