Expand description

Based on Config. Auto-generated by #[pallet::config(with_default)]. Can be used in tandem with #[register_default_config] and #[derive_impl] to derive test config traits based on existing pallet config traits in a safe and developer-friendly way.

See here for more information and caveats about the auto-generated DefaultConfig trait and how it is generated.

Required Associated Types§

source

type Time: Time

The time implementation used to supply timestamps to contracts through seal_now.

source

type RuntimeEvent

The overarching event type.

source

type RuntimeCall

The overarching call type.

source

type RuntimeHoldReason

Overarching hold reason.

source

type CallFilter

Filter that is applied to calls dispatched by contracts.

Use this filter to control which dispatchables are callable by contracts. This is applied in addition to frame_system::Config::BaseCallFilter. It is recommended to treat this as a whitelist.

§Stability

The runtime must make sure that all dispatchables that are callable by contracts remain stable. In addition Self::RuntimeCall itself must remain stable. This means that no existing variants are allowed to switch their positions.

§Note

Note that dispatchables that are called via contracts do not spawn their own wasm instance for each call (as opposed to when called via a transaction). Therefore please make sure to be restrictive about which dispatchables are allowed in order to not introduce a new DoS vector like memory allocation patterns that can be exploited to drive the runtime into a panic.

This filter does not apply to XCM transact calls. To impose restrictions on XCM transact calls, you must configure them separately within the XCM pallet itself.

source

type WeightPrice

Used to answer contracts’ queries regarding the current weight price. This is not used to calculate the actual fee and is only for informational purposes.

source

type WeightInfo: WeightInfo

Describes the weights of the dispatchables of this module and is also used to construct a default cost schedule.

source

type ChainExtension

Type that allows the runtime authors to add new host functions for a contract to call.

source

type DepositPerByte

The amount of balance a caller has to pay for each byte of storage.

§Note

It is safe to change this value on a live chain as all refunds are pro rata.

source

type DepositPerItem

The amount of balance a caller has to pay for each storage item.

§Note

It is safe to change this value on a live chain as all refunds are pro rata.

source

type CodeHashLockupDepositPercent: Get<Perbill>

The percentage of the storage deposit that should be held for using a code hash. Instantiating a contract, or calling chain_extension::Ext::lock_delegate_dependency protects the code from being removed. In order to prevent abuse these actions are protected with a percentage of the code deposit.

source

type AddressMapper

Only valid type is DefaultAddressMapper.

source

type UnsafeUnstableInterface: Get<bool>

Make contract callable functions marked as #[unstable] available.

Contracts that use #[unstable] functions won’t be able to be uploaded unless this is set to true. This is only meant for testnets and dev nodes in order to experiment with new features.

§Warning

Do not set to true on productions chains.

source

type UploadOrigin

Origin allowed to upload code.

By default, it is safe to set this to EnsureSigned, allowing anyone to upload contract code.

source

type InstantiateOrigin

Origin allowed to instantiate code.

§Note

This is not enforced when a contract instantiates another contract. The Self::UploadOrigin should make sure that no code is deployed that does unwanted instantiations.

By default, it is safe to set this to EnsureSigned, allowing anyone to instantiate contract code.

source

type Debug

For most production chains, it’s recommended to use the () implementation of this trait. This implementation offers additional logging when the log target “runtime::revive” is set to trace.

source

type Xcm

A type that exposes XCM APIs, allowing contracts to interact with other parachains, and execute XCM programs.

source

type RuntimeMemory: Get<u32>

The amount of memory in bytes that parachain nodes a lot to the runtime.

This is used in Pallet::integrity_test to make sure that the runtime has enough memory to support this pallet if set to the correct value.

source

type PVFMemory: Get<u32>

The amount of memory in bytes that relay chain validators a lot to the PoV.

This is used in Pallet::integrity_test to make sure that the runtime has enough memory to support this pallet if set to the correct value.

This value is usually higher than Self::RuntimeMemory to account for the fact that validators have to hold all storage items in PvF memory.

source

type ChainId: Get<u64>

The EIP-155 chain ID.

This is a unique identifier assigned to each blockchain network, preventing replay attacks.

Object Safety§

This trait is not object safe.
