Restaking | The Next Big Thing in the Crypto Space
As blockchain networks evolve, the demand for greater efficiency, scalability, and security continues to grow. Proof-of-Stake (PoS) systems, such as Ethereum 2.0, have addressed some challenges by allowing participants to stake tokens and secure the network in exchange for rewards. However, the question remains: how can stakers maximize their earnings while contributing to the network's resilience?This is whererestaking emerges as a game-changing solution in the realm ofdefi development services. It involves reinvesting staking rewards back into the network to compound earnings. It boosts individual returns and strengthens the overall blockchain ecosystem by increasing security and scalability. With its growing adoption among individual users, businesses, and institutions, the concept emerges as a pivotal innovation.This blog explores how restaking works, its benefits, and the transformative potential for blockchain networks. We'll also examine its role in driving innovation in decentralized finance (DeFi) and its expected impact on the blockchain landscape by 2025.Explore |Everything About Crypto Intent Prediction MarketplacesWhat is Restaking?Restaking is an emerging concept in blockchain and cryptocurrency, particularly in the context of Proof-of-Stake (PoS) systems like Ethereum 2.0. It involves taking the rewards earned from staking and reinvesting them back into the staking process. This can be done manually by the staker or automatically through smart contracts.Restaking thus, refers to the process of reinvesting staking rewards back into the staking pool, allowing stakers to compound their earnings over time. Unlike traditional staking, where rewards are distributed but not reinvested, this concept ensures that rewards generate additional returns.Before diving into more about it, let us first understand the basic difference between staking and restaking:Read Also |Comprehensive Guide to Implementing SaaS TokenizationDifference between Staking and RestakingStaking: Users lock up their tokens in a proof-of-stake (PoS) blockchain to participate in network validation, earning rewards in return.Restaking: Instead of being limited to a single staking role, it lets the same staked tokens provide security or services to additional.In PoS systems, participants stake their tokens to validate transactions and secure the network, earning rewards for their contributions. This new concept enhances this process in the either of the two ways:Manual: Stakers manually reinvest their rewards, requiring active monitoring and frequent action.Automated: Smart contracts handle the reinvestment process automatically, offering consistency and reliability without manual intervention.By leveraging the emerging concept, stakers can optimize their returns while supporting network security and decentralization.Why Restaking MattersRestaking delivers value across multiple dimensions. For stakers, it maximizes returns with minimal effort. For blockchain networks, it strengthens security, scalability, and user participation. It is not just a financial strategy — it's a mechanism that drives innovation, sustainability, and growth in decentralized ecosystems.Read Also|Crypto Staking Platform Developed by OodlesKey Benefits of RestakingCompounding RewardsThe most significant advantage is the ability to generate higher long-term earnings through compounding. For example, consider a staker with an initial $1,000 investment and an annual return of 10%. With restaking, the rewards grow exponentially as each reinvestment builds upon the previous one.Enhanced Network SecurityRestaking increases the amount of tokens locked in the network, making it more secure. A higher staking ratio reduces the likelihood of 51% attacks and ensures better decentralization. This security enhancement benefits not only the stakers but also the entire blockchain ecosystem.Increased ParticipationRestaking encourages users to remain engaged with the staking process. It fosters a culture of active participation, which strengthens blockchain networks and creates a more supportive community of validators and users.How Does Restaking WorkManual RestakingIt involves stakers periodically reinvesting their rewards. While this approach offers control over the reinvestment process, it requires consistent monitoring and effort. Missed reinvestment opportunities or delays can reduce potential earnings, making it less efficient.Automated RestakingThis strategy leverages smart contracts to reinvest rewards seamlessly. Once set up, the system operates without human intervention, ensuring that rewards are reinvested promptly. This method eliminates human error, saves time, and provides consistent results, making it the preferred choice for both individual and institutional stakers.Check it out |Exploring Crypto Arbitrage Trading Bot and DevelopmentHow Restaking Helps BusinessesUnlocking Passive Revenue StreamsBusinesses holding PoS tokens can leverage restaking to generate a steady, compounded income. This strategy is particularly appealing to organizations seeking low-risk ways to diversify their revenue portfolios.Strengthening Blockchain InvestmentsRestaking allows businesses to maximize the value of their blockchain holdings. By reinvesting rewards, companies can scale profits while aligning with long-term investment strategies.Boosting Network Support for Industry ProjectsRestaking contributes to the stability of blockchain networks hosting business operations. By reinforcing these networks, businesses benefit from enhanced reliability and scalability, creating a mutually beneficial relationship.Efficiency and Cost SavingsAutomated restaking reduces the need for active management, freeing up resources for other strategic initiatives. This cost-effectiveness makes it an attractive option for organizations of all sizes.Read Also |An Introductory Guide to Ethereum 2.0 | A Major UpgradeThe Future of Restaking in 2025Increased Adoption Across NetworksRestaking is expected to become a standard feature across PoS blockchains. Emerging projects will integrate it as core functionality, appealing to both individual and institutional participants.Enhanced Smart Contract FeaturesAdvanced smart contract features, such as adaptive restaking algorithms and AI-driven optimization tools, will make it more efficient. These innovations will allow stakers to tailor their strategies to market conditions and maximize returns.Economic and Network ImpactWidespread adoption of it will influence token value and market dynamics.

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.

Creating a Token Vesting Contract on Solana Blockchain
In the world of crypto/token development and blockchain, token vesting is a vital mechanism used to allocate tokens to individuals over a specified period rather than all at once. This approach helps to align the interests of contributors, advisors, and investors with the long-term success of a project. In this blog, we'll explore the concept of token vesting, and how it works, and dive into a practical implementation using the Simple Token Vesting contract written in Rust with the Anchor framework.What is Token Vesting?Token vesting involves gradually releasing tokens to individuals (beneficiaries) based on predefined schedules and conditions. This helps prevent immediate sell-offs and incentivises participants to stay committed to the project. The key benefits of token vesting include:Promoting Long-Term Commitment: Beneficiaries are motivated to remain involved with the project.Preventing Market Manipulation: Reduces the risk of large sell-offs that could affect the token's price.Aligning Interests: Ensures that all parties work toward the project's success over time.Also, Explore | How to Build a Crypto Portfolio TrackerThe Structure of the Simple Token Vesting ContractThe Simple Token Vesting contract provides a framework for managing token vesting on the Solana blockchain. Let's break down its main components:Initialization: The Admin sets up the contract with a list of beneficiaries and allocates tokens for them.Releasing Tokens: The Admin can release a percentage of tokens to beneficiaries periodically.Claiming Tokens: Beneficiaries can claim their vested tokens based on the amount released.#[program]
pub mod token_vesting {
use super::*;
pub fn initialize(ctx: Context<Initialize>, beneficiaries: Vec<Beneficiary>, amount: u64, decimals: u8) -> Result<()> {
// Initialization logic here...
}
pub fn release(ctx: Context<Release>, percent: u8) -> Result<()> {
// Release logic here...
}
pub fn claim(ctx: Context<Claim>, data_bump: u8) -> Result<()> {
// Claim logic here...
}
}
Also, Read | How to Deploy a TRC-20 Token on the TRON BlockchainHow the Contract Works1. Initialisation FunctionDuring initialization, the Admin calls the initialise function to set up the vesting contract. This function takes a list of beneficiaries, the total amount of tokens to vest, and the token's decimals. Here's how it looks in the code:pub fn initialize(ctx: Context<Initialize>, beneficiaries: Vec<Beneficiary>, amount: u64, decimals: u8) -> Result<()> {
let data_account = &mut ctx.accounts.data_account;
data_account.beneficiaries = beneficiaries;
data_account.token_amount = amount;
data_account.decimals = decimals;
// Transfer tokens from Admin to escrow wallet
let transfer_instruction = Transfer {
from: ctx.accounts.wallet_to_withdraw_from.to_account_info(),
to: ctx.accounts.escrow_wallet.to_account_info(),
authority: ctx.accounts.sender.to_account_info(),
};
let cpi_ctx = CpiContext::new(
ctx.accounts.token_program.to_account_info(),
transfer_instruction,
);
token::transfer(cpi_ctx, amount * u64::pow(10, decimals as u32))?;
Ok(())
}
Explanation:Parameters: The function takes a list of beneficiaries, the total token amount to be vested, and the decimals.Data Account: Initialises a data account to keep track of the beneficiaries and their allocations.Token Transfer: Transfers the specified amount of tokens from the Admin's wallet to the escrow wallet for distribution.You may also like | How to Create an ERC 721C Contract2. Release FunctionThe release function allows the Admin to specify what percentage of the total tokens is available for beneficiaries to claim. Here's the code:pub fn release(ctx: Context<Release>, percent: u8) -> Result<()> {
let data_account = &mut ctx.accounts.data_account;
data_account.percent_available = percent; // Set the available percentage
Ok(())
}Explanation:Setting Percent Available: The Admin can call this function to set a percentage that beneficiaries can claim. For example, if percent is set to 20, beneficiaries can claim 20% of their allocated tokens.3. Claim FunctionBeneficiaries use the claim function to withdraw their available tokens. Here's how it works:pub fn claim(ctx: Context<Claim>, data_bump: u8) -> Result<()> {
let data_account = &mut ctx.accounts.data_account;
let beneficiaries = &data_account.beneficiaries;
let (index, beneficiary) = beneficiaries.iter().enumerate().find(|(_, beneficiary)| beneficiary.key == *sender.to_account_info().key)
.ok_or(VestingError::BeneficiaryNotFound)?;
let amount_to_transfer = ((data_account.percent_available as f32 / 100.0) * beneficiary.allocated_tokens as f32) as u64;
// Transfer tokens to beneficiary's wallet
let transfer_instruction = Transfer {
from: ctx.accounts.escrow_wallet.to_account_info(),
to: beneficiary_ata.to_account_info(),
authority: data_account.to_account_info(),
};
let cpi_ctx = CpiContext::new_with_signer(
token_program.to_account_info(),
transfer_instruction,
signer_seeds
);
token::transfer(cpi_ctx, amount_to_transfer * u64::pow(10, data_account.decimals as u32))?;
data_account.beneficiaries[index].claimed_tokens += amount_to_transfer;
Ok(())
}Explanation:Finding Beneficiary: The function identifies the calling beneficiary from the list.Calculating Transfer Amount: It calculates how much the beneficiary can claim based on the percentage available.Token Transfer: Transfers the calculated amount from the escrow wallet to the beneficiary's associated token account.Also, Check | How to Create and Deploy an ERC404 token contractConclusionToken vesting is a powerful tool in the cryptocurrency ecosystem that promotes long-term commitment among participants.

Chain Abstraction Explained | Key Benefits You Need to Know
The world of Web3 is blooming extensively. Did you know that in Q2 of 2024, the decentralized application (dApp) industry saw a game-changing surge? Daily unique active wallets (UAW) reached an all-time high of 10 million, reflecting a remarkable 40% increase from the previous quarter. ThisDappRadar report highlights the strong growth and rising user interest in decentralized applications. However, to sustain and further accelerate this growth in dApp usage, we must address a key challenge: the complexities of navigating the decentralized web. This includes the complex Dapp navigation from different wallets, and gas fees to users switching between multiple blockchain networks. This challenge is a major concern as it impedes smooth web3 user experiences and drops significant mainstream adoption. Chain abstraction emerges as one of the keyblockchain solutions to this challenge of mass adoption in the Web3 space. It empowers developers to build applications that function seamlessly across multiple blockchains, simplifying the overall user experience. This technology alleviates complexity for users. It enables them to engage with various dApps without having to understand the details of different blockchain protocols. Consequently, it enhances accessibility and convenience, driving the overall growth of the Web3 ecosystem.In this blog, let's explore how this chain abstraction innovation is paving the way for the future of decentralized applications and Web3.Also Read |ERC-4337: Ethereum's Account Abstraction ProposalWhat is Chain AbstractionImagine if you could only send messages from an iPhone to another iPhone, but not to an Android. Frustrating, right? Now, translate that to Web3: users want to interact with decentralized applications (dApps) across different blockchains but often face unnecessary UX barriers. For instance, you might be excited to buy a new token getting lots of buzz, only to find it's on a blockchain you've never used. You don't have the right wallet, or the native token for fees. Now you have to create a wallet, learn how the blockchain works, and navigate its interface. It's time-consuming, confusing, and frankly, a roadblock to the seamless experience we expect.As more dApps expand across multiple blockchains, these challenges grow. The complexity becomes overwhelming, not just for users but also for developers looking to scale their apps across chains. How time-consuming should it be?Definition: Chain abstraction isNEAR's solution to untangling the complexities of blockchain interaction. It makes blockchain invisible to the end user. They don't need to know which blockchain they're using, or even that they're using one at all. It allows users to interact with any blockchain using a single, familiar interface, while tools and libraries handle all the technical details in the background.Chain abstraction lets users connect with any blockchain through one interface. For this, tools and libraries handle the complex details of each blockchain, simplifying the process. For example, users can buy tokens on Near, Ethereum, or Solana with their MetaMask wallet, without needing different wallets or switching blockchains.Explore|ERC 4337: Account Abstraction for Ethereum Smart Contract WalletsNeed For Chain AbstractionThe vision of Web3 stands very simple: to build a decentralized internet where users have full control over their digital interactions and assets. However, the reality of using decentralized applications (dApps) today often falls short of this goal. Users must navigate a complicated landscape of exchanges, wallets, gas fees, and different blockchain networks. This results in a disjointed, frustrating, and fragmented user experience that poses a major obstacle to widespread adoption.Also, Web3 tackled scalability by breaking blockchain functions like settlement and execution into separate parts. This shift sparked the creation of layer-2 solutions, rollups, sidechains, and state channels. While this approach boosted scalability, it also increased fragmentation. Each solution built its own ecosystem, leading to isolated liquidity pools, divided user bases, and added complexity for both developers and users.For example, a user trying to purchase an item via a dApp must first buy crypto on an exchange, transfer it to a compatible wallet, switch to the correct network, and check that they have enough gas fees. They then complete the transaction, which often involves multiple confirmations and signatures. But does this process sound anything like the seamless, user-friendly experience that Web2 applications offer? That's whychain abstraction emerges as a key development for Web3's future.As we explore the evolving Web3 landscape, several significant challenges stand out, creating friction for both developers and users:✔Handling Multiple Wallets and Addresses: Users frequently manage several wallets and blockchain addresses, complicating their digital interactions and introducing unnecessary UX friction.✔Manual Asset Bridging: Transferring assets across different blockchains generally requires manual bridging, a process that is both tedious and inconvenient.✔Navigating Gas Fees and Token Structures: The diverse gas fees and token structures across various networks add layers of complexity, forcing users to navigate unfamiliar systems.✔Network Switching: Accessing various decentralized applications (dApps) often necessitates switching between networks, which can be both confusing and frustrating for users.✔Comprehending Technical Variations: Users often struggle with the technical differences among various blockchains, making it challenging to effectively engage with decentralized applications.Check It Out |A Quick Guide to Ethereum ERC Token StandardsHow Does Chain Abstraction WorkThe concept makes interacting with multiple blockchains easier by using tools and libraries that handle the complexity for you. Instead of dealing with each blockchain individually, users can connect to any chain through a single interface, while the system quietly manages the different networks, wallets, and tokens behind the scenes. This streamlined approach allows dApps to scale smoothly across multiple chains, all while maintaining a seamless, user-friendly experience.The infographic below clearly illustrates how integrating the concept simplifies the Web3 landscape.Suggested Read |How to Create an NFT Rental Marketplace using ERC 4907Benefits of Chain AbstractionDefragmenting Liquidity and Avoiding UX FrictionChain abstraction unifies fragmented ecosystems, simplifying interactions across different blockchains.Simplified DevelopmentDevelopers can build without needing deep expertise in the specifics of each blockchain.InteroperabilityEasily connect and operate across multiple blockchains using the same interface.No Lock-InUsers can switch between or use multiple blockchains freely, without being tied to one ecosystem.Cost SavingsUsers can select blockchains with lower fees, optimizing their transactions without the hassle.Better User ExperienceChain abstraction removes the need for users to understand blockchain mechanics, delivering a smooth, intuitive experience.ScalabilityDistribute workloads across different chains, improving efficiency.Enhanced SecurityChain abstraction allows users to leverage the most secure features from different blockchains.Read Also |How to Build a Multi-Chain Account Abstraction WalletCase Studies of Chain AbstractionChain abstraction has real, tangible applications.

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

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

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

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 "CounterModule," scroll down, click "Next," choose the "Sepolia" network, and click "Publish Contract."For the Core Contract, run npx thirdweb deploy -k "THIRDWEB_API_KEY" in your terminal, 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.
