Struct pallet_revive::pallet::Pallet

pub struct Pallet<T>(/* private fields */);

The Pallet struct, the main type that implements traits and standalone functions within the pallet.

Implementations

impl<T: Config> Pallet<T>

where <<T as Config>::Currency as Inspect<<T as Config>::AccountId>>::Balance: Into<U256> + TryFrom<U256>, MomentOf<T>: Into<U256>, T::Hash: IsType<H256>,

pub fn eth_transact( origin: OriginFor<T>, payload: Vec<u8>, gas_limit: Weight, storage_deposit_limit: <<T as Config>::Currency as Inspect<<T as Config>::AccountId>>::Balance, ) -> DispatchResultWithPostInfo

A raw EVM transaction, typically dispatched by an Ethereum JSON-RPC server.

Parameters

• payload: The encoded crate::evm::TransactionSigned.
• gas_limit: The gas limit enforced during contract execution.
• storage_deposit_limit: The maximum balance that can be charged to the caller for storage usage.

Note

This call cannot be dispatched directly; attempting to do so will result in a failed transaction. It serves as a wrapper for an Ethereum transaction. When submitted, the runtime converts it into a [sp_runtime::generic::CheckedExtrinsic] by recovering the signer and validating the transaction.

pub fn call( origin: OriginFor<T>, dest: H160, value: <<T as Config>::Currency as Inspect<<T as Config>::AccountId>>::Balance, gas_limit: Weight, storage_deposit_limit: <<T as Config>::Currency as Inspect<<T as Config>::AccountId>>::Balance, data: Vec<u8>, ) -> DispatchResultWithPostInfo

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.

pub fn instantiate( origin: OriginFor<T>, value: <<T as Config>::Currency as Inspect<<T as Config>::AccountId>>::Balance, gas_limit: Weight, storage_deposit_limit: <<T as Config>::Currency as Inspect<<T as Config>::AccountId>>::Balance, code_hash: H256, data: Vec<u8>, salt: Option<[u8; 32]>, ) -> DispatchResultWithPostInfo

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.

pub fn instantiate_with_code( origin: OriginFor<T>, value: <<T as Config>::Currency as Inspect<<T as Config>::AccountId>>::Balance, gas_limit: Weight, storage_deposit_limit: <<T as Config>::Currency as Inspect<<T as Config>::AccountId>>::Balance, code: Vec<u8>, data: Vec<u8>, salt: Option<[u8; 32]>, ) -> DispatchResultWithPostInfo

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. If Some is supplied then CREATE2 semantics are used. If None then CRATE1 is used.

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.

pub fn upload_code( origin: OriginFor<T>, code: Vec<u8>, storage_deposit_limit: <<T as Config>::Currency as Inspect<<T as Config>::AccountId>>::Balance, ) -> DispatchResult

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.

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.

pub fn remove_code( origin: OriginFor<T>, code_hash: H256, ) -> DispatchResultWithPostInfo

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.

pub fn set_code( origin: OriginFor<T>, dest: H160, code_hash: H256, ) -> DispatchResult

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.

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

Register the callers account id so that it can be used in contract interactions.

This will error if the origin is already mapped or is a eth native Address20. It will take a deposit that can be released by calling Self::unmap_account.

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

Unregister the callers account id in order to free the deposit.

There is no reason to ever call this function other than freeing up the deposit. This is only useful when the account should no longer be used.

pub fn dispatch_as_fallback_account( origin: OriginFor<T>, call: Box<<T as Config>::RuntimeCall>, ) -> DispatchResultWithPostInfo

Dispatch an call with the origin set to the callers fallback address.

Every AccountId32 can control its corresponding fallback account. The fallback account is the AccountId20 with the last 12 bytes set to 0xEE. This is essentially a recovery function in case an AccountId20 was used without creating a mapping first.

impl<T: Config> Pallet<T>

A generalized version of Self::call.

Identical to Self::call but tailored towards being called by other code within the runtime as opposed to from an extrinsic. It returns more information and allows the enablement of features that are not suitable for an extrinsic (debugging, event collection).

A generalized version of Self::instantiate or Self::instantiate_with_code.

Identical to Self::instantiate or Self::instantiate_with_code but tailored towards being called by other code within the runtime as opposed to from an extrinsic. It returns more information and allows the enablement of features that are not suitable for an extrinsic (debugging, event collection).

pub fn bare_eth_transact( tx: GenericTransaction, gas_limit: Weight, utx_encoded_size: impl Fn(Call<T>) -> u32, ) -> Result<EthTransactInfo<<<T as Config>::Currency as Inspect<<T as Config>::AccountId>>::Balance>, EthTransactError>

A version of Self::eth_transact used to dry-run Ethereum calls.

Parameters

• tx: The Ethereum transaction to simulate.
• gas_limit: The gas limit enforced during contract execution.
• utx_encoded_size: A function that takes a call and returns the encoded size of the unchecked extrinsic.

pub fn evm_balance(address: &H160) -> U256

A generalized version of Self::upload_code.

It is identical to Self::upload_code and only differs in the information it returns.

pub fn get_storage(address: H160, key: [u8; 32]) -> GetStorageResult

Query storage of a specified contract under a specified key.
