The rise of Bitcoin-based token standards has introduced new opportunities—and complexities—for crypto users. Among the most discussed innovations is BRC-20, a token standard built on the Bitcoin blockchain using the Ordinals protocol. As more exchanges like Gate.io begin supporting BRC-20 tokens, it’s essential for users to understand how deposits, withdrawals, and inscriptions work to avoid costly mistakes and maximize utility.
This guide breaks down everything you need to know about BRC-20 token management, from technical foundations to practical steps for secure transfers—all while ensuring compatibility with wallet and exchange requirements.
What Are BRC-20 Tokens?
BRC-20 is an experimental token standard that leverages Bitcoin's Ordinals system to inscribe data—such as JSON code representing fungible tokens—onto individual satoshis (the smallest unit of Bitcoin). Unlike ERC-20 tokens on Ethereum, BRC-20 tokens do not rely on smart contracts. Instead, they use text-based inscriptions to define token creation, transfers, and balances.
While innovative, this approach introduces unique limitations:
- No native support for automated transfers or approvals.
- Transactions require manual execution via compatible wallets.
- Each transfer involves a two-step process: deployment and minting/transfer.

How Bitcoin Inscriptions Work
At the heart of BRC-20 lies the Ordinals theory, which assigns a unique identifier to each satoshi based on its mining order. This allows users to "inscribe" digital content—images, text, or code—onto specific satoshis, effectively turning them into unique digital artifacts.
These inscriptions are stored directly on the Bitcoin blockchain through SegWit (Segregated Witness) and Taproot upgrades, which allow for more efficient data storage. When a BRC-20 token is created, its metadata (name, symbol, supply) is inscribed as JSON text within a transaction.
For example:
{"p":"brc-20","op":"deploy","tick":"pepe","max":"1000000","lim":"1000"}This single line of text becomes permanently recorded on the blockchain and represents the launch of a new BRC-20 token called “pepe” with a maximum supply of 1 million and a per-mint limit of 1,000 tokens.
Because these inscriptions are immutable and decentralized, they inherit Bitcoin’s security but also face scalability challenges due to block size constraints and higher transaction fees during peak usage.
Depositing BRC-20 Tokens to Exchanges
Not all cryptocurrency platforms support BRC-20 tokens, and those that do often impose strict requirements due to technical complexity.
Key Requirements for Deposit:
- Native Bitcoin Network Address: BRC-20 tokens must be sent via the Bitcoin network (BTC) using Bech32 (bc1q) addresses.
- UTXO Integrity: The UTXO (Unspent Transaction Output) containing the inscribed satoshi must remain intact. Splitting or combining UTXOs may result in loss of the inscription.
- No Wallet Wrapping: Sending through intermediary services like multisig wallets or wrapped asset protocols can strip away inscription data.
To deposit safely:
- Use a dedicated BRC-20-compatible wallet (e.g., Unisat, Xverse, or Leather).
- Confirm the exchange supports direct BRC-20 deposits over the BTC network.
- Double-check the receiving address format—only native SegWit (bc1q) addresses are supported.
- Start with a small test transaction before sending larger amounts.
Failure to follow these steps may result in irreversible loss of funds—a common issue reported by inexperienced users.
Withdrawing BRC-20 Tokens: Critical Precautions
Withdrawing BRC-20 tokens requires even greater caution than depositing. Many users have lost tokens by accidentally sending them to incompatible addresses or using incorrect network paths.
Best Practices for Withdrawal:
- Verify Wallet Compatibility: Ensure your receiving wallet explicitly supports BRC-20 inscriptions.
- Use Correct Address Format: Always send to a bc1q Bech32 address—avoid legacy (1...) or P2SH (3...) formats.
- Avoid Exchange Intermediaries: Do not route withdrawals through third-party custodial services unless confirmed inscription-safe.
- Preserve UTXO Structure: Never consolidate inscribed UTXOs without full understanding of the implications.
Some exchanges may offer automated tools to manage BRC-20 transfers, but manual verification remains crucial. Always review transaction details before confirmation.

Common Mistakes and How to Avoid Them
Despite growing awareness, many users still encounter problems when handling BRC-20 tokens. Here are some frequent errors:
| Issue | Cause | Solution |
|---|---|---|
| Lost inscriptions | Sending via non-compatible wallets | Use only verified BRC-20 wallets |
| Failed deposits | Using wrong address format | Confirm bc1q format before sending |
| High fees | Congested network periods | Monitor mempool activity; schedule during low congestion |
| Irreversible transactions | No smart contract rollback | Double-check all details pre-sign |
Since Bitcoin transactions are irreversible and lack smart contract reversibility features, user diligence is paramount.
Frequently Asked Questions (FAQ)
What is the difference between BRC-20 and ERC-20 tokens?
BRC-20 tokens are based on Bitcoin using the Ordinals protocol and store data via inscriptions. They lack smart contract functionality. ERC-20 tokens run on Ethereum and support programmable logic, enabling automatic transfers, staking, and DeFi integration.
Can I send BRC-20 tokens using any Bitcoin wallet?
No. Only wallets that support Ordinals and BRC-20 inscriptions can properly handle these tokens. Standard BTC wallets may treat inscribed UTXOs as regular Bitcoin, risking loss of data or value.
Why did my deposit fail even though I used the correct address?
Even with the right address, if the UTXO containing the inscribed satoshi was altered (e.g., merged or split), the inscription may no longer be recognized. Always preserve UTXO integrity during transfers.
Are BRC-20 transactions reversible?
No. Like all Bitcoin transactions, BRC-20 transfers are final once confirmed. There is no mechanism for chargebacks or recovery if sent incorrectly.
Does every exchange support BRC-20?
No. Support is still limited and evolving. Always verify whether an exchange accepts BRC-20 tokens before initiating any transfer.
Is there a gas fee for BRC-20 transfers?
Yes. Since BRC-20 operates on Bitcoin, users pay standard BTC network fees based on transaction size and network congestion. These can be significantly higher than Ethereum Layer 2 or other low-cost networks.
The Future of Bitcoin-Based Tokens
As interest in Bitcoin-native assets grows, projects are exploring ways to improve scalability and functionality for standards like BRC-20. Emerging solutions include:
- BitVM – enabling Turing-complete computation on Bitcoin.
- RGB Protocol – layer-two smart contracts anchored to Bitcoin.
- Nostr Band – leveraging social layer protocols for token distribution.
While BRC-20 remains experimental, it has sparked renewed innovation in the Bitcoin ecosystem, proving that even the oldest blockchain can evolve with community-driven development.
