How to Create a Multi-Signature Wallet on Solana using Rust What is a Multi-Signature Wallet?Multi-signature (multi-sig) wallets play a crucial role in enhancing the security and reliability of cryptocurrency transactions. Unlike standard wallets, which rely on a single private key for control, multi-sig wallets require approvals from multiple private keys before a transaction can be authorized. This shared-approval mechanism reduces the risk of a single point of vulnerability, making multi-sig wallets especially valuable for teams, DAOs, and organizations that manage funds collectively. By spreading responsibility across multiple key holders, these wallets ensure that no single user has unchecked control over the funds, increasing security and accountability. Explore more about crypto wallets with our crypto wallet development services.In a multi-sig wallet, a configuration is set to require a specific number of approvals (M) out of a total number of keys (N) to authorize a transaction. For instance, a 2-of-3 multi-sig setup means that any two of the three signatories must approve a transaction before it can be completed. This structure enables a system of mutual oversight, where each participant plays a role in safeguarding assets, greatly reducing the likelihood of misuse or unauthorized access.Additionally, multi-sig wallets support more transparent, collaborative governance structures, which align well with the decentralized ethos of blockchain technology. By requiring multiple approvals, these wallets allow for shared decision-making and control, empowering groups to protect assets in a secure, decentralized manner.In this developer's guide, we will explore the steps to create a multi-signature wallet on Solana.Prerequisite TechnologiesBefore proceeding with the implementation, make sure to have the following tools and technologies ready:Rust: The main programming language used for development on Solana.Solana CLI: Tools that allow command-line interaction with the Solana blockchain.Rust libraries: A good understanding of Rust libraries that assist with cryptographic operations and account management.You may also like | Develop a Multi-Token Crypto Wallet for Ethereum with Web3.jsCode Implementation | Creating a Multi-Signature Wallet on SolanaBelow are the essential components of the multi-sig wallet implementation.

Boost Engagement with Geo-Fencing Push Notifications for Your App When it comes tomobile apps for the retail sector, engaging customers at the right time and place has become a key factor in driving business success. Geo-fencing-based push notifications have emerged as a powerful tool to enhance user engagement, offering businesses a way to deliver targeted, location-based messages in real-time.Whether you run a retail business, a restaurant, or an event-based service, geo-fencing can help you interact with customers in a personalized and meaningful way. This article explores what geo-fencing-based push notifications are, how they work, and why they're a game-changer for businesses.Why Geo-Fencing-Based Push Notifications Matter for Your BusinessGeo-fencing is a technology that creates virtual boundaries around specific locations, such as a store, stadium, or neighborhood. When users with your mobile app installed enter or exit these predefined areas, they receive a push notification on their device. These notifications can include anything from special promotions and discounts to personalized messages and reminders.Geo-fencing works by leveraging GPS, Wi-Fi, or cellular data to detect a user's location in real-time. It allows businesses to reach users when they are in close proximity to a specific location, making interactions timely, relevant, and highly engaging.Geo-fencing-based push notifications provide several benefits for businesses looking to engage customers more effectively:1. Location-Based TargetingGeo-fencing allows you to target users based on their physical location, which means you can reach them when they are most likely to interact with your brand. Whether you're sending promotions to customers near your store or providing directions to event attendees, location-specific targeting makes your message more relevant.2. Enhanced Customer EngagementTiming is everything in marketing. With geo-fencing, you can engage customers with timely and contextual messages, prompting them to take immediate action. For example, a restaurant could send out lunch-time deals when users are nearby, or a retail store could push out flash sales when a customer is close to one of its outlets.3. Cost-Effective MarketingCompared to traditional forms of marketing, geo-fencing-based notifications are cost-effective. They allow businesses to communicate directly with users who are more likely to convert due to their proximity to your physical location, leading to higher ROI on your marketing efforts.4. Personalized User ExperienceGeo-fencing enables a highly personalized experience for users. By sending location-relevant messages, businesses can cater to individual needs and preferences, enhancing customer satisfaction and loyalty. Imagine sending a notification welcoming a customer to your store with an exclusive discount, just as they walk through the door.Also Read: Beyond Native: Why Cross-Platform is the New Enterprise StandardReal-World Use Cases of Geo-Fencing inMobile AppsSeveral industries have adopted geo-fencing technology to drive engagement and improve customer experiences.

How to Write and Deploy Modular Smart Contracts Modular contracts enable highly configurable and upgradeable smart contract development, combining ease of use with security. They consist of two main components:Core Contracts: These form the foundation of the modular system, managing key functions, data storage, and logic. Core contracts include access control mechanisms and define interfaces for module interactions.Module Contracts: These add or remove functionalities to/from core contracts dynamically, allowing for flexibility. Modules can be reused across multiple core contracts, enabling upgrades without redeploying the core contract.How They Work: Modules provide additional functionality via callback and fallback functions that interact with core contracts. Fallback functions operate independently, while callback functions augment core contract logic, enhancing dApp functionality.You may also like | How to Create Play-to-Earn Gaming Smart ContractsSetup | Writing and Deploying Modular Smart ContractsInstall Forge from Foundry and add the modular contract framework:forge init forge install https://github.com/thirdweb-dev/modular-contracts.git forge remappings > remappings.txt ContractThe ERC20Core contract is a type of ERC20 token that combines features from both the ModularCore and the standard ERC20 contract. It names the token "Test Token" and uses "TEST" as its symbol, with the deployer being the owner of the contract. A significant feature is the required beforeMint callback, which allows certain actions to be taken before new tokens are created. The mint function lets users create tokens while ensuring the callback is executed first. The BeforeMintCallback interface makes it easier to add custom logic from other contracts. Overall, ERC20Core offers a flexible way to develop custom tokens while maintaining essential ERC20 functions.// SPDX-License-Identifier: UNLICENSED pragma solidity ^0.8.13; import {ModularCore} from "lib/modular-contracts/src/ModularCore.sol"; import {ERC20} from "lib/solady/src/tokens/ERC20.sol"; contract ERC20Core is ModularCore, ERC20 { constructor() { _setOwner(msg.sender); } function name() public view override returns (string memory) { return "Test Token"; } function symbol() public view override returns (string memory) { return "TEST"; } function getSupportedCallbackFunctions() public pure virtual override returns (SupportedCallbackFunction[] memory supportedCallbacks) { supportedCallbacks = new SupportedCallbackFunction[](1); supportedCallbacks[0] = SupportedCallbackFunction(BeforeMintCallback.beforeMint.selector, CallbackMode.REQUIRED); } function mint(address to, uint256 amount) external payable { _executeCallbackFunction( BeforeMintCallback.beforeMint.selector, abi.encodeCall(BeforeMintCallback.beforeMint, (to, amount)) ); _mint(to, amount); } } interface BeforeMintCallback { function beforeMint(address to, uint256 amount) external payable; } Also, Read | ERC 4337 : Account Abstraction for Ethereum Smart Contract WalletsThe PricedMint contract is a modular extension designed for token minting, leveraging Ownable for ownership management and ModularExtension for added functionality. It uses the PricedMintStorage module to maintain a structured storage system for the token price. The owner can set the minting price through the setPricePerUnit method. Before minting, the beforeMint function verifies that the provided ether matches the expected price based on the token quantity. If correct, the ether is transferred to the contract owner. The getExtensionConfig function defines the contract's callback and fallback functions, facilitating integration with other modular components.// SPDX-License-Identifier: UNLICENSED pragma solidity ^0.8.13; import {ModularExtension} from "lib/modular-contracts/src/ModularExtension.sol"; import {Ownable} from "lib/solady/src/auth/Ownable.sol"; library PricedMintStorage { bytes32 public constant PRICED_MINT_STORAGE_POSITION = keccak256(abi.encode(uint256(keccak256("priced.mint")) - 1)) & ~bytes32(uint256(0xff)); struct Data { uint256 pricePerUnit; } function data() internal pure returns (Data storage data_) { bytes32 position = PRICED_MINT_STORAGE_POSITION; assembly { data_.slot := position } } } contract PricedMint is Ownable, ModularExtension { function setPricePerUnit(uint256 price) external onlyOwner { PricedMintStorage.data().pricePerUnit = price; } function beforeMint(address to, uint256 amount) external payable { uint256 pricePerUnit = PricedMintStorage.data().pricePerUnit; uint256 expectedPrice = (amount * pricePerUnit) / 1e18; require(msg.value == expectedPrice, "PricedMint: invalid price sent"); (bool success,) = owner().call{value: msg.value}(""); require(success, "ERC20Core: failed to send value"); } function getExtensionConfig() external pure virtual override returns (ExtensionConfig memory config) { config.callbackFunctions = new CallbackFunction ; config.callbackFunctions[0] = CallbackFunction(this.beforeMint.selector); config.fallbackFunctions = new FallbackFunction ; config.fallbackFunctions[0] = FallbackFunction(this.setPricePerUnit.selector, 0); } } DeployTo deploy the Modular Contract, first get your API Key from the Thirdweb Dashboard. Then run npx thirdweb publish -k "THIRDWEB_API_KEY", replacing "THIRDWEB_API_KEY" with your key.

Select "CounterCore," enter the contract owner's address, and click "Deploy Now." Choose the "Sepolia" chain and click "Deploy Now" again to start the deployment.Also, Explore | How to Create a Smart Contract for Lottery SystemConclusionModular contracts represent a design approach in smart contract development that prioritizes flexibility, reusability, and separation of concerns. By breaking down complex functionalities into smaller, interchangeable modules, developers can create more maintainable code and implement updates more easily without losing existing state. Commonly utilized in token standards and decentralized finance (DeFi), modular contracts enhance the creation of decentralized applications (dApps) and promote interoperability, thereby fostering innovation within the blockchain ecosystem.
