BRC-20 and ERC-20 are token standards that create fungible crypto tokens. They sound similar, but they run on different chains:
- BRC-20 tokens are created on Bitcoin using Ordinal inscriptions,
- while ERC-20 tokens run on Ethereum, mainly via smart contracts.
That small difference changes how these tokens are created, how they move, how they’re used inside decentralized apps, and even how wallets and exchanges end up supporting them.
For users involved in Bitcoin Trading, understanding how BRC-20 tokens work can also help put Bitcoin-based digital assets into perspective. While BRC-20 focuses on fungible tokens built on Bitcoin, Bitcoin Trading generally involves buying, selling, or speculating on Bitcoin and related markets.
Delta Exchange is the top destination for traders who want to trade crypto options chain.
In simple terms, BRC-20 brings fungible tokens to Bitcoin, while ERC-20 is a more programmable setup for building tokens and apps on Ethereum.

Key Takeaway
- BRC-20 tokens are inscribed on Bitcoin through Ordinals; ERC-20 tokens run as smart contracts on Ethereum.
- BRC-20 can’t do much beyond minting and transferring. It’s mostly used for speculative, experimental tokens.
- ERC-20 supports actual code execution, so it powers DeFi lending, gaming items, staking, and governance voting.
- BRC-20 depends on wallets and indexers that don’t all agree on the standard yet. ERC-20 tokens inherit whatever bugs sit in their smart contract, plus the risk of approving a malicious contract to spend your tokens.
What Is a BRC-20 Token?
Let’s understand the meaning of BRC first – it’s the acronym for Bitcoin Improvement Proposal, which is how new standards in Bitcoin’s protocol are proposed.
BRC-20 is an experimental token standard that showed up on the Bitcoin blockchain in 2023. It uses the Ordinals protocol to inscribe JSON data onto single satoshis – basically the smallest Bitcoin unit.
Unlike a typical Ethereum token, a BRC-20 token doesn’t depend on a smart contract to track balances and move funds. Instead, the token’s rules are basically written into the blockchain through inscriptions, then interpreted by compatible wallets, marketplaces, and indexers.
BRC-20 tokens can be deployed, minted, and transferred. But their capabilities feel narrower than ERC-20 tokens because they don’t include programmable smart contracts.
The BRC-20 description from CoinMarketCap says ERC-20 inspired the standard, but it was built specifically for the Bitcoin network.
What is an ERC-20 token?
An ERC-20 (ERC standing for Ethereum Request for Comment) is a standard interface for fungible tokens on Ethereum; it lets tokens behave consistently. Proposed in 2015, it defines common functions so tokens can work with wallets, decentralized exchanges, and other blockchain apps in a plug-and-play way. It’s basically the backbone of how all Ethereum tokens exist today.
An ERC-20 smart contract can handle things like:
- Token transfers
- Account balances
- Total supply
- Spending approvals
- Token calls or interactions with other contracts
The official ERC-20 specification then defines the standard functions and events that compatible tokens should support.
Since ERC-20 tokens run on smart contracts, devs can attach extra features, like staking, lending, governance, automated payments, and even decentralized exchange capabilities.
BRC-20 vs ERC-20: Main Differences
| Feature | BRC-20 | ERC-20 |
| Blockchain | Bitcoin | Ethereum |
| Technical foundation | Ordinal inscriptions | Smart contracts |
| Token management | Interpreted through inscriptions and indexers | Managed directly by a smart contract |
| Programmability | Limited | Extensive |
| Main ecosystem | Bitcoin | Ethereum and EVM-compatible networks |
| Common use | Fungible tokens and experimental projects | DeFi, gaming, governance and utility tokens |
| Maturity | Newer and experimental | Established and widely adopted |
The biggest difference is programmability. BRC-20 tokens use inscriptions to record token activity, while ERC-20 tokens use smart contracts to enforce rules on-chain.
So How Do BRC-20 and ERC-20 Tokens Get Created?
In practice, it looks pretty different for each one. For BRC-20, you don’t “deploy” anything the usual way. Instead, you write certain JSON inscriptions straight into the Bitcoin blockchain. Those inscriptions spell out the token ticker, the maximum amount, and the minting limit. After that, compatible indexers read the inscriptions and maintain the balances as they go.
This also means everything is attached to Bitcoin transaction activity. If the network is crowded, like seriously congested, then minting or sending a BRC-20 token will be slower, and the costs can jump.
ERC-20 token creation is usually done by deploying a smart contract on Ethereum. That contract sets the supply, the transfer logic, and a bunch of related functions. Teams can tweak the contract too, for example, adding burning options, minting controls, fee mechanics, or even access limitations depending on the design.
Smart contracts bring more flexibility, but you also get more potential trouble. If there are coding blunders, or permissions aren’t designed well, or if vulnerabilities slip in, then the ERC-20 token’s security can be impacted, sometimes in a big way.
Which One Is More Useful between BRC-20 and ERC-20?
Most of the time, ERC-20 is the default choice when a project needs programmability and easy integration with decentralized applications. Developers can plug ERC-20 tokens into lending protocols, staking services, decentralized exchanges, gaming apps, and governance setups with little friction.
BRC-20 is only more appealing if users care about activity happening specifically on Bitcoin. It’s more of a demo showing that Bitcoin’s transaction handling and inscription features can support new kinds of digital assets. In many cases, it has less wallet support, fewer applications, and weaker interoperability compared to the more established ERC-20 ecosystem.
So if you’re doing Bitcoin-based token experiments and want something simple and fungible, BRC-20 will always make more sense. If you’re thinking of DeFi, gaming, governance, or any kind of programmable app, then ERC-20 fits better.
Before you buy either one, review liquidity and wallet support… I mean, check it first, not after. Also, look closely at the token contract or the inscription details, because those parts matter more than people casually assume. And yeah, don’t assume that a token standard automatically means legitimacy or value; it’s not that simple.
BRC-20 vs ERC-20: Security and Risks
BRC-20 tokens can ride on Bitcoin’s underlying network security, but the extra layers around it can still lead to problems. Indexers, wallets, and marketplaces might interpret inscriptions slightly differently, and in the worst cases, users can lose funds by sending tokens to addresses that don’t match what the system expects.
ERC-20 tokens are obviously a more mature ecosystem given their age, but the smart contract risk is still a big deal. A malicious contract, or just a poorly audited one, could have hidden minting mechanisms, awkward transfer limitations, or excessive approval permissions that allow more access than you thought.
Also remember transaction costs can shift on both sides. Bitcoin congestion may push inscription fees upward, while Ethereum gas fees can jump too, especially when demand for block space gets high.
And if you’re using futures, perpetuals, or other derivatives, don’t forget leverage and liquidation risk. Even technical analysis doesn’t counter that. Traders can explore those markets via Delta Exchange India, but derivatives risk is separate from the token standard itself.
So in short – BRC-20 and ERC-20 are both sort of “rules” for fungible crypto tokens, just for different ecosystems. Like, BRC-20 leans on Bitcoin inscriptions, and it tends to feel more straightforward, less programmable, more like “here’s the thing and it sits there.” Meanwhile, ERC-20 is tied to Ethereum smart contracts, and it can do a lot more, so it opens the door to a broader menu of apps, DeFi stuff, gaming, governance, you name it.
The Bottom Line
So if you’re doing Bitcoin-focused experiments, BRC-20 is your go-to. But if your goal is DeFi, gaming, governance, or broader blockchain applications, then ERC-20 is your primary option, without question.
And before you go for any token type, don’t just look at the hype. Check liquidity, wallet compatibility, the contract or inscription details, developer information, and the bigger, practical use case behind it.
