When Bitcoin was introduced in 2009 it revolutionized decentralized transactions. While Ethereum dominated the NFT market, Bitcoin enthusiasts were satisfied until Casey Rodarmor introduced ordinals N

Bitcoin (BTC) and Ethereum (ETH) have been major catalysts for the cryptocurrency industry, each sparking a wave of innovation and ushering in many new use cases. These pioneers were early proponents of decentralization and security, which helped to spotlight the transformative potential of blockchain technology.

Foreword Over the past decade, Bitcoin has demonstrated remarkable innovation and resilience, even during times of challenging market conditions. It has introduced groundbreaking elements to the modern monetary system, internet technology, and financial sectors, thereby establishing itself as a prominent asset in the global mainstream.

The introduction of ERC-7579 demonstrates a commitment to improving the current standards, specifically ERC-6900 , to create a more user — and developer-friendly experience. Additionally, ERC-7579 seeks to enhance the capabilities of ERC-4337, opening up new possibilities in the field. Here's our technical guide on how ERC-7579 works.

MetaMask is a popular cryptocurrency wallet that allows users to securely store, manage, and interact with Ethereum and other Ethereum-compatible cryptocurrencies. The wallet is available as a browser

Crypto moves at "lightning" speed, and there's been lots of momentum behind new token standards and protocols recently. Some have hailed them as significant innovations, while others have dismissed th

ConsenSys is the leading global blockchain technology company behind a groundbreaking new solution that's helping address Ethereum's scalability challenge — Linea . To date, ConsenSys has been pivotal in advancing the adoption and development of decentralized applications (DApps) on the Ethereum blockchain. Founded by Joseph Lubin, one of the co-founders of Ethereum, ConsenSys has emerged as a key player in the blockchain space.

2023 has seen many AI innovations emerge, from conversational wonders like ChatGPT to extraordinary feats in generative AI. These advancements have undoubtedly reshaped how we interact, work, and play. But are they also opening the door to fresh challenges?

## What is ERC-6551? ERC-6551 Token Bound Accounts (TBA) is a new and innovative Ethereum standard that expands the functionality of NFTs by allowing them to operate as their own smart contract accoun

The emergence of  ordinals  and  BRC-20 tokens  sparked a lively debate within the Bitcoin community. On the one hand, enthusiasts celebrated the newfound potential these innovations bring to the Bitcoin blockchain. On the other hand, concerns have been raised about the rise in gas fees, longer transaction times, and the potential occupation of valuable block space by ordinals and BRC-20 tokens.

When we're using browser extensions to choose an Ethereum provider, how can we make the process is stable and user-controlled, given the unpredictable loading order of EIP-1193 standards? Enter EIP-6963.

Have you ever felt restricted by the boundaries of a single blockchain network when managing your assets? With cross-chain token transfers from financial services company Circle, restrictions are a thing of the past. They help break down those sometimes frustrating obstacles so you can move crypto like effortlessly from networks like and Cosmos.

Avalanche is a blockchain platform designed for decentralized applications and enterprise solutions. It aims to provide faster transaction times, lower fees, and increased scalability compared to othe

If you've been in the crypto scene for long enough, you'll definitely have heard of teething issues like network outages for layer-1 blockchains like Solana and Aptos . These issues can be traced back to the monolithic design of such blockchains, where bottlenecks occur because networks are overwhelmed by complex transactions and user demand. Fortunately, with modular blockchain projects like Celestia and its TIA tokens, such overhead constraints due to the will become a thing of the past.

The blockchain industry has been focusing on developing Web 3.0 for several years now. This has led to the development of the metaverse, interoperability, decentralized finance (DeFi), and other produ

Blockchains are usually self-contained systems and lack the ability to communicate with other chains, creating difficulties for users when transferring money. The purpose of building what the crypto space call ‘bridges’ is to address this issue. Through , individuals can efficiently transfer their funds between different chains. Cryptocurrency bridges promote blockchain interoperability and enhance the ease of digital asset transfer. 

Solana is a popular competitor to Ethereum, offering high performance and fast transaction speeds. Users can bridge to Solana from Ethereum and other chains to explore its ecosystem. Solana uses a combination of Proof of History (PoH) consensus mechanism alongside Proof of Stake (PoS), to get to a theoretical capacity of 710,000 transactions per second (TPS). Solana’s smart contracts have created a thriving ecosystem of DeFi and NFT marketplaces. 

Arbitrum is a popular Ethereum Layer 2 (L2) solution, making bridging in and out of it essential. Arbitrum uses a method called “optimistic rollup,” where smart contracts are executed off-chain and only the final output is posted to the Ethereum blockchain. It has a significantly larger transaction throughput, making it faster and cheaper than Ethereum. Arbitrum is also an Ethereum equivalent blockchain, making it easy for developers to move their applications from the Ethereum chain.

Optimism is a popular Ethereum Layer 2 (L2) blockchain designed to increase scalability. As a result, bridging is an essential part of using the technology. Optimism increases efficiency by processing transactions off Ethereum and periodically syncing them. This results in transaction fees and processing speed being significantly lower than Ethereum, making one of the most popular Ethereum L2 solutions. 

Blockchains are typically isolated systems and can't interact with other chains, making it inconvenient for users to move funds. Blockchain bridges are built to solve this. Blockchain bridging allows users to move their funds from one chain to another quickly. Cryptocurrency bridges enable blockchain interoperability and make digital asset transfer even more convenient. 

Blockchains are independent networks that cannot communicate with each other. To address this issue, developers have created blockchain bridges . These bridges enable users to seamlessly transfer their funds between different chains. By facilitating blockchain interoperability, cryptocurrency bridges make the transfer of digital assets even simpler. 

Getting familiar with cryptocurrency bridging is essential to your crypto journey. If you’re looking for a detailed guide on how to bridge to Polygon, you’ve come to the right place. Let's explore how to bridge ETH to Polygon using Polygon’s portal and OKX Swap. Additionally, we’ll walk through a centralized bridging process using OKX to bridge USDT from Ethereum to Polygon.
