If you’ve ever sent cryptocurrency, you know that brief moment of anxiety. You’ve hit 'send,' and your funds have vanished into the digital world. Is the transaction going through? Did it arrive safely?

This is where the TXID comes in. It’s your proof, your receipt, and your peace of mind all rolled into one. Think of it like this: when you order a package online, you get a tracking number. You can use that number to see exactly where your package is and when it will arrive.  A TXID, which stands for blockchain transaction ID, does the exact same thing for your crypto. Let's demystify this powerful tool.

So, What Exactly is a TXID or Transaction Hash?

A TXID (also known as a transaction hash) is a unique string of letters and numbers that serves as a permanent, unchangeable proof that a specific crypto transaction took place.

Every single time you send or receive cryptocurrency, that action is recorded on the blockchain. The TXID is the unique "name" or "fingerprint" given to that specific record. It contains all the essential details: the sender's address, the receiver's address, the amount sent, and a timestamp.

Because it’s recorded on the blockchain, it’s immutable—meaning it can never be altered or erased. This transparency is one of the core strengths of cryptocurrency.

How to Find and Use Your TXID

Knowing what a TXID is one thing; knowing how to use it is what empowers you. The process is simple and is the key to verifying any transaction you make.

Step 1: Find Your TXID

After you make a transaction, your wallet or exchange will provide the TXID in your transaction history. On platforms like BYDFi, you can find this in your 'Withdrawal History' section. It will look like a long, random string of characters. Simply copy it.

Step 2: Go to a Blockchain Explorer

A blockchain explorer is a website that acts as a search engine for the blockchain. Each blockchain has its own explorer. For example:

What Is DAG Crypto? The Shocking Truth About Constellation’s 10x Potential in 2025 – Read Before You Buy

In the volatile world of cryptocurrencies—where Bitcoin dominates headlines and Ethereum powers the DeFi revolution—there’s a quiet but powerful contender that’s starting to attract serious attention: Constellation DAG.

If you’ve ever found yourself typing  What is DAG crypto?  into Google or wondering whether that recent DAG price dip is a red flag or a golden opportunity, you’re not alone. Many traders are starting to realize that the next 10x gem might not come from meme coins or speculative hype, but from real technology designed to fix blockchain’s deepest flaws.

As someone who’s been writing about crypto markets for years and watching trends from the heart of Europe, I can tell you—Constellation DAG is not another pump-and-dump. It’s a unique project with both military-grade engineering and long-term potential. In a space filled with empty promises, DAG is quietly building the infrastructure that could power the next generation of Web3.

So, what makes DAG crypto so different? And why are some analysts whispering that this could be one of the most underrated tokens of 2025?

What Is DAG Crypto? The Technology Behind the Buzz

To understand DAG, imagine Bitcoin’s blockchain as a long, single-lane highway. Every transaction must wait in line to be verified by the one before it. It’s reliable but painfully slow and energy-hungry.

Now, imagine a futuristic city with thousands of roads all running simultaneously—no traffic jams, no waiting. That’s what DAG, or Directed Acyclic Graph technology, does. Instead of transactions lining up in a chain, each one confirms multiple others at once, creating a web of data that’s faster, lighter, and infinitely scalable.

Constellation Network, the project behind DAG crypto, took this concept to another level. Founded in 2017 by a team of U.S. Air Force veterans and data engineers, their vision was to create a  network of networks.  They wanted to make it possible for organizations—governments, enterprises, even individual developers—to share massive amounts of data securely and efficiently without relying on centralized intermediaries.

In simple terms, Constellation is building the digital highways of the future. Imagine logistics companies tracking global shipments in real time, or defense systems sharing sensitive information instantly across borders—all without risking privacy or security breaches.

That’s where Constellation’s DAG coin comes into play. It fuels this entire ecosystem, enabling participants to validate, secure, and monetize data.

You now understand the strategy of [cross-chain yield farming] and are armed with the knowledge of its primary risk, [impermanent loss]. You are ready to start hunting for opportunities. But you are immediately faced with a new, overwhelming problem: a universe of thousands of protocols scattered across dozens of blockchains. How can you possibly find the best yields and track your investments in such a fragmented landscape? The answer is not to do it manually. The answer is to use a DeFi yield farming aggregator.

The Solution: A "Google Flights" for DeFi Yields

Think of a yield aggregator as a powerful dashboard or a "search engine" for all of DeFi. Instead of you having to visit PancakeSwap on BSC, then Uniswap on Ethereum, then Trader Joe on Avalanche, these platforms aggregate all the data from these disparate sources into a single, clean interface. They are the essential tool that allows a serious DeFi user to monitor the entire market, track their portfolio, and discover new opportunities efficiently.

Zapper: The All-in-One DeFi Hub

Zapper is one of the most popular and user-friendly aggregators available. Its strength lies in its clean, intuitive dashboard that gives you a complete overview of your entire DeFi portfolio across multiple chains and wallets. You simply connect your wallet, and Zapper instantly displays your net worth, your staked assets, your LP positions, and any outstanding debts. Beyond just tracking, Zapper's signature feature is its "Zap" functionality, which allows you to enter or exit complex liquidity pool positions in a single transaction, saving you time and gas fees. It is an excellent all-around choice for both new and experienced DeFi users.

Zerion: The Mobile-First Portfolio Tracker

While also available on desktop, Zerion has carved out a niche with its exceptional mobile app experience. It is designed for the DeFi user who wants to manage their portfolio on the go. Zerion excels at tracking a wide array of assets, including obscure altcoins and NFTs, often displaying them correctly when other platforms might fail. It allows you to connect and track multiple wallets simultaneously, making it a powerful command center for users who segment their activities across different addresses. If your primary need is a best-in-class tool for monitoring your entire multi-chain net worth from your phone, Zerion is a top contender.

DeBank: The Power User's Dashboard

DeBank is the aggregator of choice for the data-obsessed power user. While its interface may be less beginner-friendly than Zapper or Zerion, it provides an unparalleled level of detail. DeBank's strength is its comprehensive transaction history and its "Approval" checker, a crucial security tool that shows you which smart contracts you have given permission to spend your tokens. It also features a built-in Web3 social feed, allowing you to follow the on-chain activities of prominent crypto investors and "whales." If you want the most granular data and the most powerful security tools, DeBank is the platform for you.

The Final Piece of the Puzzle

These aggregators are indispensable tools for discovery and management, but they are not a substitute for due diligence. They will show you the yields, but it is still your job to research the protocols, understand the risks, and build a sound strategy. They are the map, but you are still the driver.

Imagine a digital butler that manages your entire financial life—staking your Ethereum, rebalancing your portfolio, and finding the best yields in DeFi, all while you sleep. No pop-ups, no manual approvals, just an autonomous bot working 24/7 in your best interest.

This is the promise of AI Agents in crypto.

While we see "robo-advisors" in traditional finance, Web3 is lagging behind. Why? Because the current blockchain infrastructure was built for humans, not robots. For AI agents to truly take off, the underlying architecture of the crypto world needs a massive upgrade.

In this guide, we explore the critical missing pieces of Web3 infrastructure for AI agents, the solutions being built right now, and the top projects leading this revolution.

Why Web3 Isn't Ready for AI (Yet)

The original promise of Web3 was a permissionless, open internet—a perfect playground for AI. However, the reality is clunky. Current decentralized applications (dApps) assume a human is sitting behind the screen, clicking buttons and verifying transactions.

For an AI agent to function autonomously, it faces three major infrastructure hurdles:

1. The Identity Crisis (Decentralized Identity)

In Web2, you log in with a username or email. In Web3, you use a wallet address. But for an AI agent to be trusted by other agents or smart contracts, it needs more than just a string of characters.

• The Fix: Programmable Identity. Agents need verifiable credentials (VCs) that prove who they are, their reputation score, and their history, without relying on a centralized server.

2. Wallet UX for Machines

Crypto wallets like MetaMask are designed with a User Interface (UI) for human eyes—colorful buttons and confirmation pop-ups. An AI agent cannot "click" a button.[

• The Fix: Machine-Readable Wallets. We need wallets that can interpret code-based instructions and execute transactions automatically based on pre-set logic.

3. Permission Frameworks (The "All-or-Nothing" Problem)

Right now, if you give an app your private key, it has total control over your funds. This is too risky for an AI agent.

• The Fix: Programmable Permissions. We need systems similar to "OAuth" in Web2, where you can grant an AI agent limited permission (e.g., "You can trade up to $100 of ETH, but you cannot withdraw funds").

The Missing Layers: Compute and Data

While identity and wallets are crucial, an AI agent also needs a brain (Compute) and memory (Data). This is where the "infrastructure gap" provides a massive opportunity for new crypto projects.

• Decentralized Compute: AI models require immense processing power to run. Centralized servers (like AWS) are risky and expensive. Projects like Render (RNDR) and Akash Network (AKT) are building decentralized GPU marketplaces where AI agents can rent computing power on demand.
• Verifiable Data: An AI agent is only as good as the data it is fed. If an agent is making trading decisions, it needs accurate, tamper-proof data. Oracles like Chainlink (LINK) and data graphs like The Graph (GRT) are the backbone of this reliability.

Top Projects Building the AI Agent Infrastructure

For investors and developers, the value lies in the projects solving these specific bottlenecks. Here are the key players building the rails for the AI agent economy:

1. Fetch.ai (FET) / Artificial Superintelligence Alliance (ASI):
   The leader in creating autonomous economic agents. Their infrastructure allows users to build and deploy agents that can perform tasks like booking travel or optimizing supply chains on the blockchain.
2. Gnosis Safe (SAFE):
   Solving the wallet issue. Their multi-signature and smart account technology allow for programmable logic, making it safer to delegate funds to an AI agent without giving up total control.[1]
3. Lit Protocol:
   Focused on decentralized access control. It allows users to define strict rules (policies) for how their private keys are used, effectively enabling the "Programmable Permissions" needed for safe AI agents.
4. Ocean Protocol (OCEAN):
   Addresses the data layer by allowing AI agents to buy and sell data securely while preserving privacy.

The Future: When AI Meets DeFi

Once this infrastructure is built, we will witness a shift from "DeFi" (Decentralized Finance) to "AgentFi."

• Automated Arbitrage: Agents spotting price differences across 10 exchanges instantly.
• Self-Paying Wallets: Wallets that automatically pay for gas fees or subscriptions without human input.
• Dao Management: AI agents voting on governance proposals based on the optimized outcome for the protocol.

The "AI Agent" narrative is not just hype; it is the necessary evolution of Web3 usability.

Conclusion

Web3 infrastructure is currently undergoing a radical transformation to welcome its new users: machines. The projects building the identity, security, and compute layers for these AI agents are likely to define the next bull market cycle. This is your chance to get in early on the infrastructure that will power the future of automation.

Forging the Future of Finance: A Deep Dive into Crypto Wallet Development for 2025 and Beyond

The digital gold rush of the 21st century isn't happening in remote hills; it's unfolding on the blockchain. As we gaze into the horizon of 2025, the demand for secure, intuitive, and powerful gateways to this new world—cryptocurrency wallets—is not just growing; it's exploding. With the entire crypto market cap poised to surge past an astonishing $5 trillion in the coming years, the opportunity to build a foundational piece of this ecosystem has never been more compelling.

This isn't merely about coding a piece of software; it's about crafting a digital vault, a personal bank, and a passport to the decentralized web, all rolled into one. Whether you're an entrepreneur with a vision to democratize finance or a developer fascinated by the mechanics of blockchain, understanding how to create a robust crypto wallet is the first step toward leaving your mark on the digital economy. Let's embark on a journey to unravel the intricacies of crypto wallet development, exploring the technical depth, strategic foresight, and user-centric philosophy required to succeed.

Understanding the Heart of the Matter: What Truly Is a Crypto Wallet?

At its core, a cryptocurrency wallet is a misnomer. It doesn't actually  store  your digital coins in the way a physical wallet holds cash. Instead, it’s an elegant piece of technology that manages the cryptographic keys—the private and public keys—that grant you ownership and control over your assets on the blockchain.

The public key is like your account number, which you can share to receive funds, while the private key is your unforgeable, secret signature that authorizes transactions. Whoever holds the private key controls the assets, irrevocably.

This fundamental understanding is crucial. The entire purpose of blockchain wallet development shifts from simply holding coins  to providing an impregnable and seamless interface for key management. In the rapidly evolving landscape of Web3, wallets have matured into dynamic hubs.

They are no longer passive storage units but active gateways for interacting with decentralized applications (dApps), trading NFTs, earning yield through DeFi protocols, and participating in global, borderless economies. The wallet you build could become the primary lens through which a user in Nigeria, India, or the United States experiences the entire universe of digital assets.

Navigating the Wallet Landscape: Choosing Your Path

Before a single line of code is written, a critical strategic decision must be made: what kind of wallet will you create? This choice will define your target audience, your security model, and your development roadmap.

The first major fork in the road is the choice between hot and cold wallets. A hot wallet is connected to the internet, offering unparalleled convenience for daily transactions. Think of mobile app wallets or browser extensions; they are perfect for active traders and users who need quick access to their funds. However, this constant connectivity presents a larger attack surface for hackers. A cold wallet, on the other hand, stores private keys completely offline, often on a specialized hardware device or even a piece of paper. This is the Fort Knox of crypto storage, ideal for long-term  HODLers  safeguarding significant wealth, but at the cost of instant accessibility.

The second critical decision revolves around control: custodial versus non-custodial. In a custodial model, a third-party service—like a major exchange—holds your private keys on your behalf. This is akin to a traditional bank, offering user-friendly features like password recovery, which makes it a comfortable entry point for beginners. The trade-off is that you are not in ultimate control; you are trusting the custodian with your assets.

The non-custodial model is the pure embodiment of the not your keys, not your crypto  philosophy. Here, the user alone possesses and manages their private keys. This offers complete autonomy and security from the failure or misconduct of a central entity, but it also places the full burden of responsibility on the user. Losing the private key means losing access to the funds forever, with no customer service line to call.

The Architect's Blueprint: A Philosophical Approach to Building Your Wallet

Creating a successful wallet is a symphony of engineering, design, and strategic thinking. It's a process that demands more than just technical execution.

It begins with a clear and empathetic vision. You must intimately understand the user you are building for. Are you creating a simple, custodial wallet for a first-time crypto buyer in the Philippines who wants to send remittances? Or are you building a sophisticated, non-custodial Web3 wallet for a DeFi power user in South Korea who needs to interact with a dozen different protocols daily? The answers to these questions will dictate every subsequent decision, from the blockchain you build on to the features you prioritize.

Selecting your foundational blockchain platform is a strategic commitment. Ethereum remains the bedrock for Web3 wallet development, boasting a massive ecosystem of dApps, NFTs, and smart contracts. However, networks like Binance Smart Chain offer dramatically lower transaction fees, a vital consideration for users in cost-sensitive markets. Solana

promises blazing-fast transaction speeds for those prioritizing scalability, while the "multi-chain" approach is becoming increasingly popular. Building a wallet that can natively interact with multiple blockchains is a complex undertaking, but it future-proofs your product and offers users unparalleled flexibility, allowing them to navigate the entire crypto universe from a single interface.

In the world of crypto, security is not a feature; it is the product. A single, high-profile security breach can shatter user trust beyond repair. Therefore, your development process must be obsessed with security from the ground up.

This means implementing bank-grade encryption for private keys, never storing them on central servers in a non-custodial model, and incorporating multi-layered defenses. Features like Two-Factor Authentication (2FA) and biometric logins (fingerprint or facial recognition) add critical barriers against unauthorized access.

For advanced users or business accounts, multi-signature (multi-sig) functionality, which requires several private keys to authorize a transaction, can be a game-changer for shared asset management and enhanced security.

Yet, all the security in the world is meaningless if the wallet is confusing or difficult to use. The user experience must be so intuitive that it feels like magic. Sending crypto should be as simple as sending a message on WhatsApp. The design must be clean, the transaction flow must be unambiguous, and the process of backing up a recovery phrase must be educational and foolproof. Furthermore, to achieve true global reach, your wallet must speak the user's language—both linguistically and financially. Supporting multiple languages and displaying values in local currencies like the Euro, Indian Rupee, or Nigerian Naira is not an afterthought; it's a necessity for mass adoption.

To stand out in 2025, your wallet must be more than a keychain; it must be a key to the entire decentralized city. This means integrating a built-in dApp browser, allowing users to seamlessly connect to platforms like Uniswap or Aave without leaving your app. Native support for viewing and trading NFTs, the ability to stake assets directly from the wallet to earn passive income, and real-time portfolio tracking are the features that transform a utility into a destination.

Confronting the Inevitable Hurdles

The path to a successful launch is paved with significant challenges. The global regulatory landscape for cryptocurrencies is a complex and shifting patchwork. Navigating Know Your Customer (KYC) and Anti-Money Laundering (AML) regulations in jurisdictions from the U.S. to the UK requires careful legal counsel to ensure your wallet operates compliantly and builds trust with both users and financial institutions.

As your user base grows, so will the strain on your infrastructure. Ensuring your wallet can handle peak transaction volumes during market frenzies is a testament to its architectural integrity. This is where the choice of a scalable underlying blockchain and a robust backend system becomes critically important.

Finally, in an industry once scarred by scams and hacks, earning and retaining user trust is your most valuable currency. This trust is built through transparency—consider making your code open-source for community scrutiny—and through professional, regular security audits conducted by reputable third-party firms.

The Engine Room: Tools and a Sustainable Model

A Hidden Gem in the 2025 Crypto Market

The cryptocurrency market is moving fast. We have transitioned from the era of slow, expensive Layer 1 blockchains to the high-speed "express lanes" of Layer 2. Now, as we approach 2026, we are entering the era of Layer 3.

Layer 3 networks, or "App-Chains," are specialized blockchains dedicated to a single specific purpose—like a high-performance video game or a decentralized social network. They offer what previous generations could not: zero gas fees for users, instant speeds, and complete customization.

For investors, this represents a massive shift. Capital is beginning to flow into these specialized ecosystems. In this guide, we highlight the top Layer 3 projects and the infrastructure tokens that are best positioned to dominate this new sector in 2026.

1. Xai (XAI)

If you are betting on crypto gaming driving mass adoption, Xai is the project to watch. Built on top of Arbitrum, Xai was developed specifically to solve the biggest headache in blockchain gaming: the complexity.

What makes it unique?
Xai operates as a Layer 3 that "abstracts away" the blockchain. This means traditional gamers can play games, trade items, and earn rewards without ever needing to manage a complex crypto wallet or pay gas fees.

Why it is a top pick for 2026?
As more AAA-quality games launch on the blockchain, they need a home that can handle millions of transactions per second without clogging up. Xai is currently the frontrunner in this space, making it a high-potential play for the upcoming gaming cycle.

2. Degen (DEGEN)

Degen is one of the most fascinating stories in the crypto space. It started as a simple reward token for users of the "Farcaster" social media protocol but quickly evolved into its own Layer 3 blockchain built on Base.

What makes it unique?
Degen is the first "community-first" Layer 3. It is designed specifically for low-cost, high-frequency micro-transactions—like tipping a content creator a few cents. Because it is an L3, these transactions cost fractions of a penny.

Why it is a top pick for 2026:
The "SocialFi" (Social Finance) sector is predicted to grow massively. Degen has captured a loyal, cult-like following that rivals major memecoins, but it has the technical utility of a serious blockchain.

3. Arbitrum (ARB)

While Arbitrum is technically a Layer 2 scaling solution, it is the most critical infrastructure player for the Layer 3 revolution. Through its technology stack called Arbitrum Orbit, it allows developers to launch their own Layer 3 chains easily.

What makes it unique?
Think of Arbitrum as the landlord. When projects like Xai (and dozens of others) build their Layer 3 chains, they build them on top of Arbitrum. This secures their networks and drives value back to the Arbitrum ecosystem.

Why it is a top pick for 2026:
Investing in Arbitrum is the safer "infrastructure bet." Instead of trying to pick which specific Layer 3 game or app will win, you are betting on the platform that powers them all.

4. Optimism (OP)

Optimism has a grand vision called the Superchain. They are not just building a blockchain; they are building a network of interconnected Layer 2 and Layer 3 chains that can all talk to each other seamlessly.

What makes it unique?
The "OP Stack" is the software that powers this vision. It has been adopted by some of the biggest names in the world. For example, Coinbase used it to build their Base chain, and Sony is exploring it for their own blockchain initiatives.

Why it is a top pick for 2026:
As major corporations enter Web3, they are choosing the OP Stack to build their custom chains. This institutional adoption positions Optimism as a titan of Layer 3 infrastructure for years to come.

5. Orbs (ORBS)

Orbs sits in a unique position. It doesn't try to replace L1s or L2s; instead, it acts as a decentralized backend that enhances them. It is often referred to as "Layer 3" infrastructure because it handles complex logic that smart contracts on Ethereum can't handle efficiently.

What makes it unique?
Orbs focuses on making DeFi trading better. It powers advanced trading protocols, liquidity aggregators, and decentralized derivatives.

Why it is a top pick for 2026:
As Decentralized Finance (DeFi) tries to compete with traditional stock markets, it needs the advanced execution logic that Orbs provides. It is a vital piece of plumbing for the financial side of crypto.

How to Position Your Portfolio

The "Layer 3" narrative is all about specialization.

• For high growth potential, look at specific Layer 3 tokens like Xai (XAI) and Degen (DEGEN).
• For long-term stability, look at the foundational layers that host these chains, specifically Arbitrum (ARB) and Optimism (OP).
