Implementation of a safe with modules enabled in a transaction: a guide
Ethereum is a decentralized platform of open source blockchain that allows developers to build and implement intelligent contracts, DAPPS (decentralized applications) and other autonomous systems. When it comes to implementing a safe and autonomous container for confidential data, you must ensure that all the necessary modules are enabled and implemented in a single transaction. In this article, we will explore the best methods to achieve this goal.
** What is a safe?
A safe is a type of intelligent contract that can be used to store and manage confidential information, such as private keys, wallet addresses or other confidential data. The safes are designed to provide an additional layer of safety and control over access to these resources.
The best method: Implement safes with modules enabled in a transaction
To implement a safe with multiple modules enabled in a transaction, you can use the following steps:
- Create a new safe contract : First, create a new intelligent contract for your safety using solidity (the programming language used to build Ethereum contracts). For example:
`SOLIDITY
Pragma solidity ^0.8.0;
Safe contract {
Go to the public owner;
Mapping (address => bool) isowner public;
Builder () public {
Owner = msg.sender;
iswner [msg.sender] = True;
}
Function Deposit () Public Pagable {
It requires (isawner [msg.sender], "you are not the owner of this safe");
// add your own logic to handle deposits here
}
RETAMPER FUNCTION (_receiver) public {
It requires (isawner [msg.sender], "you are not the owner of this safe");
Require (_receiver! = Address (0), "The receiver is zero-direction");
Payable (_receiver) .transfer (quantity);
}
}
- Add modules to the safe contract : To enable multiple modules, you must add them as separate components to your safe contract. One way to do it is through the use of the
externalcall 'function of the ERC-165 interface of Openzeppelin. For example:
SOLIDITY
Pragma solidity ^0.8.0;
Safe contract {
Internal internercall _positmodule;
Internualcall Internal _withdrawmodule;
Builder () public {
_Positmodule = New Externalcall ("Safedeposit", "Safe");
_Withdrawrodule = New External Call ("Safewithdrawal", "Safe");
}
Function Deposit () Public Pagable {
_depositmodule.call ();
}
RETAMPER FUNCTION (_receiver) public {
_withdrawrodule.call (_receiver);
}
}
- Create separate transactions
: To implement your safe contract with multiple enabled modules, you can create separate transactions for the implementation of each module. This will ensure that the necessary components are implemented in a single lot.
The best method: using a transaction builder
Alternatively, you can use a transaction building to simplify the implementation process of multiple safe contracts with enabled modules. A popular option is the 'Txbuilder' library, which provides a simple API to build transactions in the Ethereum network.
Here is an example of how you can create two separate transactions:
` SOLIDITY
Pragma solidity ^0.8.0;
Import «
Contract owner {
Go to the public owner;
Mapping (address => bool) isowner public;
Builder () public {
Owner = msg.sender;
iswner [msg.sender] = True;
}
Function Deposit () Public Pagable {
It requires (isawner [msg.sender], « you are not the owner of this safe »);
// add your own logic to handle deposits here
}
}
SAFE1 contract {
Address the public owner1;
Mapping (address => bool) isowner public;
Builder () public {
Owner1 = msg.
