Required Methods

fn set_storage( key_ptr: u32, key_len: u32, value_ptr: u32, value_len: u32, ) -> Result<u32, TrapReason>

Set the value at the given key in the contract storage. See [pallet_contracts_uapi::HostFn::set_storage_v2]

Wasm Import Statement

(import "seal2" "set_storage" (func ...))

fn call( flags: u32, callee_ptr: u32, ref_time_limit: u64, proof_size_limit: u64, deposit_ptr: u32, value_ptr: u32, input_data_ptr: u32, input_data_len: u32, output_ptr: u32, output_len_ptr: u32, ) -> Result<ReturnErrorCode, TrapReason>

Make a call to another contract. See [pallet_contracts_uapi::HostFn::call_v2].

Wasm Import Statement

(import "seal2" "call" (func ...))

fn instantiate( code_hash_ptr: u32, ref_time_limit: u64, proof_size_limit: u64, deposit_ptr: u32, value_ptr: u32, input_data_ptr: u32, input_data_len: u32, address_ptr: u32, address_len_ptr: u32, output_ptr: u32, output_len_ptr: u32, salt_ptr: u32, salt_len: u32, ) -> Result<ReturnErrorCode, TrapReason>

Instantiate a contract with the specified code hash. See [pallet_contracts_uapi::HostFn::instantiate_v2].

Wasm Import Statement

(import "seal2" "instantiate" (func ...))

fn seal_set_storage( key_ptr: u32, key_len: u32, value_ptr: u32, value_len: u32, ) -> Result<u32, TrapReason>

This is just an alias function to set_storage() with backwards-compatible prefixed identifier.

Wasm Import Statement

(import "seal2" "seal_set_storage" (func ...))
