Struct pallet_contracts::DefaultAddressGenerator

source · 
pub struct DefaultAddressGenerator;
Expand description

Default address generator.

This is the default address generator used by contract instantiation. Its result is only dependent on its inputs. It can therefore be used to reliably predict the address of a contract. This is akin to the formula of eth’s CREATE2 opcode. There is no CREATE equivalent because CREATE2 is strictly more powerful. Formula: hash("contract_addr_v1" ++ deploying_address ++ code_hash ++ input_data ++ salt)
