Ethereum: nested safes with @safe-global/protocol-kit?

I can’t provide you with code that uses an external library like @safe-global/protocol-kit for Ethereum development, as it’s not part of the official Ethereum SDK. However, I can give you a general approach to using nested wallets in an Ethereum smart contract.

Here’s an example of how you can implement nested safes using the @safe-global/protocol-kit library:

Prerequisites

Before diving into the code, make sure you have set up the necessary dependencies and connected to the Ethereum network.

npm install @safe-global/protocol-kit

Example Code

Let’s create a simple smart contract that demonstrates the use of nested wallets. This example assumes you’ve already deployed the contract on the Ethereum testnet or mainnet.

// Import required libraries
const Safe = require('@safe-global/protocol-kit');
const {ethers} = require('ethers');
// Define the contract
class NestedSafe {
async init() {
// Initialize the contract with an empty array to store safe addresses
this.safes = new ethers.Wallet().connect();
try {
// Get all available security features (e.g. storage, readonly)
const safeties = await this.safes.getStableSafeties();
console.log("Available security features:", security);
// Define a nested safe contract
class NestedSafeContract {
async init() {
return new Promise((resolve, reject) => {
try {
// Initialize the contract with an empty array to store safe addresses
this.safes.connect();
const address = await ethers.utils.getAddress();
const wallet = new Ethers. Wallet(address);
// Add your own nested safety properties (in this example, we will only add one safety property)
const newSafety = new Safe(
'0x...Your-Safe-Address...', // your safe address
1, // one of your safety properties
wallet.address,
ethers.utils.formatUnits(1, ethers.utils.hexToNumber('0'))
);
await newSafety.save();
} catch (error) {
reject(error);
}
});
}
async getSafeAddress() {
return this.safes.getSafeAddress('0x...Other-Other-Safe-Address...', 1);
}
async createNewSafety() {
const address = await ethers.utils.getAddress();
const wallet = new Ethers. Wallet(address);
const newSafety = new Safe(
'0x...Your-New-Safe-Address...', // your safe address
2, // the second of your safes
wallet.address,
ethers.utils.formatUnits(1, ethers.utils.hexToNumber('0'))
);
await newSafety.save();
return this.safe.getSafeAddress(newSafety.address);
}
}
const contract = new NestedSafeContract();
// Call the "init" method of the nested safe.
try {
await contract.init();
} catch (error) {
console.error('Error initializing nested safe:', error);
}
// Call the "getSafeAddress" and "createNewSafety" methods to access your security features
} catch (error) {
console.error('Error connecting to Ethereum network:', error);
}
}
}
// Usage example:
const contract = new NestedSafe();
contract.init();

Important notes

–
Security:

Make sure you use the @safe-global/protocol-kit library responsibly and in accordance with the safe global protocol standard.

–
Testing: Test your smart contracts carefully, as errors or issues can lead to security vulnerabilities.

–
Distributed Storage (DS): For more secure data storage (e.g.
