What Is BNB Chain?
BNB Chain, formerly known as Binance Smart Chain (BSC), is a high-performance blockchain ecosystem that supports decentralized applications (DApps), smart contracts, and digital assets. Launched on September 1, 2020, and rebranded as BNB Chain in February 2022, it operates alongside the original Binance Chain to offer both fast transaction speeds and robust smart contract functionality.
At the heart of this ecosystem is BNB, the native cryptocurrency that powers transactions, staking, governance, and more. Originally launched as an ERC-20 token on Ethereum in July 2017, BNB transitioned to its own blockchain to enhance scalability and reduce costs. Today, BNB plays a central role across multiple layers of the crypto economy—from exchange fee discounts to DeFi participation.

Core Functions of BNB Chain
Scalability and Low-Cost Transactions
One of the standout features of BNB Chain is its ability to process transactions quickly and affordably. With average fees around $0.10 and block times of just 3 seconds, it offers a compelling alternative to more congested networks like Ethereum. This efficiency has made BNB Chain a popular choice for developers building decentralized finance (DeFi) platforms, NFT marketplaces, and gaming applications.
The network’s Ethereum Virtual Machine (EVM) compatibility allows seamless migration of Ethereum-based DApps with minimal code changes. Tools like MetaMask, Truffle, and Hardhat work natively with BNB Chain, lowering the barrier to entry for developers.
Thriving Ecosystem Growth
By May 2024, BNB Chain supported over 1,500 DApps, including major platforms such as:
- PancakeSwap – a leading decentralized exchange (DEX)
- Venus – a lending and borrowing protocol
- BakerySwap – a multi-functional DeFi platform combining yield farming and NFTs
These projects have helped drive significant user adoption. The total value locked (TVL) in BNB Chain’s DeFi protocols surpassed $20 billion, reflecting strong confidence from investors and users alike.
Token Utility: Why BNB Matters
Multi-Purpose Cryptocurrency
BNB is far more than just a trading token. Its utility spans across several key areas:
- Transaction fees: Users pay gas fees in BNB when interacting with DApps or transferring assets.
- Staking rewards: Validators and delegators earn annual returns ranging from 5% to 15%, depending on network conditions and stake size.
- Governance participation: Holders can vote on proposals that influence protocol upgrades and ecosystem development.
- Launchpad access: BNB grants eligibility to participate in exclusive token sales via Binance Launchpad.
Deflationary Supply Model
BNB follows a deflationary economic model designed to increase scarcity over time. Binance initially committed to burning 50% of its total supply—100 million BNB tokens—through periodic buybacks and destruction events.
While early burns were conducted quarterly, the process evolved into an automated mechanism called the Auto-Burn, which adjusts based on network activity and BNB market price. This dynamic approach ensures long-term supply reduction aligned with ecosystem growth.
Founders Behind the Vision
Changpeng Zhao (CZ)
As co-founder and former CEO of Binance, Changpeng Zhao played a pivotal role in shaping the global crypto landscape. With prior experience at Bloomberg and fintech firms, CZ entered the blockchain space in 2013 and launched Binance in 2017. Under his leadership, the exchange rapidly became the world’s largest by trading volume, paving the way for innovations like BNB Chain.
He Yi
Co-founder and former Chief Marketing Officer (CMO), He Yi brought critical marketing expertise to Binance. Her background in media and previous co-founding role at OKCoin—a major Chinese fiat-to-crypto exchange—helped position Binance for international success. Her strategic branding efforts contributed significantly to early user acquisition and global recognition.
Key Risks to Consider
While BNB Chain offers strong technological advantages, investing in or using BNB comes with inherent risks:
- Regulatory scrutiny: Regulatory bodies like the U.S. Securities and Exchange Commission (SEC) have expressed concerns about BNB’s classification and potential securities implications.
- Competition in Layer-1 space: Newer blockchains such as Solana, Avalanche, and Arbitrum continue to challenge BNB Chain with faster speeds, lower fees, or better scalability solutions.
- Smart contract vulnerabilities: Despite audits, code defects or exploits could compromise DApps or user funds.
- Market volatility: Like all cryptocurrencies, BNB is subject to sharp price swings influenced by macroeconomic trends and sentiment shifts.
- Cybersecurity threats: Phishing attacks, wallet breaches, and exchange hacks remain ongoing risks.
- Forking risk: Network upgrades may lead to chain splits, creating uncertainty for users and developers.
Investors should conduct thorough research and assess their risk tolerance before engaging with any crypto asset.

Frequently Asked Questions (FAQ)
What is the difference between Binance Chain and BNB Chain?
Binance Chain was originally built for fast trading and asset transfers but lacked smart contract capabilities. BNB Chain (formerly Binance Smart Chain) added EVM-compatible smart contract functionality. In 2022, they were unified under the “BNB Chain” brand to represent a cohesive ecosystem.
Can I stake BNB outside of Binance?
Yes. You can stake BNB directly on the BNB Chain by becoming a validator or delegating to one. This decentralized staking option allows users to earn rewards without relying on centralized exchanges.
How does the BNB Auto-Burn work?
The Auto-Burn mechanism automatically destroys BNB tokens based on two factors: the number of blocks produced on the chain and the average market price of BNB. This creates a deflationary pressure tied to network usage and demand.
Is BNB a good investment?
BNB has demonstrated strong utility and ecosystem growth, but like all crypto investments, it carries volatility and regulatory risks. Long-term potential depends on continued adoption of the BNB Chain and expansion of its DApp ecosystem.
What wallets support BNB Chain?
Popular EVM-compatible wallets like MetaMask, Trust Wallet, and MathWallet fully support BNB Chain. Users can easily switch networks within these wallets to interact with DApps.
How do I bridge assets to BNB Chain?
You can use official cross-chain bridges like the BNB Chain Bridge or third-party solutions such as Multichain or Celer Network to transfer tokens from Ethereum or other chains to BNB Chain.
Uphold’s Due Diligence Process
Before listing BNB, Uphold conducted comprehensive due diligence evaluating multiple dimensions:
- Technology review: Source code openness, audit history, peer reviews, security practices, and roadmap viability.
- Market analysis: Liquidity, supply-demand dynamics, maturity level, and real-world utility.
- Marketing assessment: Evaluation of content across social channels including Twitter, Medium, LinkedIn, Discord, and Telegram.
- Risk evaluation: Technical vulnerabilities (e.g., hacking susceptibility, fork risks), legal exposure (regulatory actions), and compliance status.
Uphold concluded that BNB is unlikely to be classified as a security under current securities legislation—a key factor in its decision to list the asset.
