What Are BRC-20 Tokens?
A Beginner’s Guide to Bitcoin’s First Fungible Token Standard
When people think of Bitcoin, they often think of it as “digital gold” — a store of value, not something that can host token ecosystems like Ethereum. But in 2023, that all changed with the creation of BRC-20 tokens — a simple yet powerful experiment in bringing fungible tokens to Bitcoin.
Here’s what BRC-20 tokens are, how they work, and why they’ve kicked off a new era of Bitcoin innovation.
The Basics
BRC-20 is an experimental token standard on Bitcoin that allows for the creation and transfer of fungible tokens using Ordinals inscriptions.
It was introduced by a pseudonymous developer named Domo in March 2023, as a way to prove you could do ERC-20–style tokens without smart contracts, using only JSON text files inscribed on satoshis.
How Do BRC-20 Tokens Work
Instead of using code to define how a token behaves (like on Ethereum), BRC-20 tokens work by:
-
Inscribing JSON files onto individual sats (via the Ordinals protocol)
-
Each file represents an action:
-
"deploy"a token -
"mint"new supply -
"transfer"between wallets
-
These inscriptions are stored permanently on Bitcoin and interpreted by compatible wallets and marketplaces.
🧠 Note: BRC-20 tokens do not use smart contracts. Everything is stored as data on-chain, making the system more transparent — but also more clunky and limited.
Why BRC-20 Tokens Took Off
Despite their limitations, BRC-20 tokens exploded in popularity due to:
-
Simplicity — no smart contracts, just data files
-
True on-chain permanence (stored on Bitcoin itself)
-
Massive speculation on early meme tokens (like $SATS and $PEPE)
-
Community-driven experimentation
Within months, BRC-20 markets had over $1 billion in volume.
What Can You Use BRC-20 Tokens For?
While many are still meme-based, use cases are growing:
-
Community coins (for fanbases, creators, DAOs)
-
In-game currency for Bitcoin-native games
-
Access tokens for exclusive content or groups
-
Airdrops and marketing campaigns
They can also serve as training wheels for future, more advanced Bitcoin tokens like Runes.
Limitations to Know
Because BRC-20 wasn’t built for scale:
-
They’re inefficient (lots of JSON file bloat)
-
Require off-chain indexers to track balances
-
High gas fees during minting booms
-
Still experimental — not a finalized Bitcoin standard
How to Explore BRC-20 Tokens
You can browse BRC-20 tokens at sites like:
You can also buy, sell, or create your own BRC-20 tokens using wallets that support them like Xverse, Hiro, and Unisat.

What's Next?
BRC-20 was just the beginning. It opened the door for standards like:
-
Runes – more efficient, cleaner token model
-
ARC-20 – for tokenizing on Stacks layer
-
CBRC-20 – using inscriptions with added compression
Still, BRC-20 has carved out a place in Bitcoin history — as the first real wave of token speculation, community coins, and creative chaos directly on-chain.
