BRC-20 is an experimental token standard on the Bitcoin network, inspired by Ethereum's ERC-20 but operating through a fundamentally different mechanism. Introduced in 2023 by a developer known as "domo," BRC-20 leverages Bitcoin's Ordinals and Inscriptions to embed data directly onto satoshis (the smallest units of Bitcoin), creating a token ecosystem atop Bitcoin's blockchain.
How Does BRC-20 Work?
Unlike ERC-20 on Ethereum, BRC-20 doesn't rely on smart contracts. Instead, it uses Ordinal Inscriptions to record transaction data directly on Bitcoin's blockchain. Each BRC-20 token is created through a "minting" process and can be traded using wallets that support Ordinals.
Key Features of BRC-20
- No Smart Contracts: Relies solely on data inscribed via Bitcoin's Ordinals.
- Bitcoin Network Dependency: Transactions are processed like standard Bitcoin transactions, potentially leading to high fees during network congestion.
- Limited Scalability: The absence of smart contracts restricts complex applications compared to ERC-20.

BRC-20 vs. ERC-20: A Comparison
| Feature | BRC-20 | ERC-20 |
|---|---|---|
| Platform | Bitcoin | Ethereum |
| Smart Contracts | Not supported | Fully supported |
| Token Creation | Ordinal-based | Smart contract-driven |
| Transaction Fees | Higher during congestion | More flexible fee options |
| Scalability | Limited | Robust (supports DeFi) |
How to Trade BRC-20 Tokens
To trade BRC-20 tokens, follow these steps:
- Set Up a Compatible Wallet: Use wallets like Ordinal Wallet, Unisat Wallet, or Xverse Wallet.
- Mint or Receive Tokens: Acquire BRC-20 tokens via minting or peer transfers.
- Trade on Supported Platforms: Platforms like Unisat or Magic Eden facilitate BRC-20 trading.
- Ensure Sufficient BTC for Fees: Transaction fees are paid in Bitcoin.
Risks of Investing in BRC-20
While promising, BRC-20 carries risks:
- Experimental Stage: No long-term guarantees exist.
- Network Congestion: High fees during peak usage.
- Limited Liquidity: Not all exchanges support BRC-20, impacting liquidity.

The Future of BRC-20
BRC-20 could evolve into a significant player in Bitcoin's ecosystem, but scalability and performance challenges remain. Technological advancements may bolster its adoption for Bitcoin-based tokens.
FAQs
1. Can BRC-20 tokens be stored in any Bitcoin wallet?
No, only wallets supporting Ordinals (e.g., Unisat, Xverse) can hold BRC-20 tokens.
2. Are BRC-20 tokens as versatile as ERC-20 tokens?
Not currently—BRC-20 lacks smart contracts, limiting advanced functionalities like DeFi integrations.
3. Why are BRC-20 transaction fees higher?
Fees depend on Bitcoin’s network congestion, as BRC-20 transactions are processed like standard Bitcoin transfers.
4. Is BRC-20 officially supported by Bitcoin?
No, it’s an experimental standard built atop Bitcoin via Ordinals.
5. Where can I track BRC-20 token prices?
Specialized platforms like Unisat or OKX provide price tracking and trading.
Conclusion
BRC-20 represents an innovative expansion of Bitcoin’s utility, enabling token creation without smart contracts. However, its experimental nature and scalability constraints warrant cautious engagement. For those exploring BRC-20, thorough research and selecting reliable platforms are essential.
