BRC20 Phase 2 is now active on Bitcoin Mainnet, bringing full programmability and smart contracts to the mother chain. 🟠🟧
With this upgrade, BRC20 delivers truly native Bitcoin DeFi, enabling stablecoins, RWA tokenization, and on-chain applications, all on Bitcoin L1.
Throughout 2025, @bestinslotxyz have proven the value of the maintainership model, and the work they’ve put in can’t be overstated. Excited to see how the community experiments with the new expressiveness and UX of the module. Worthless or not, test with care :)
BRC2.0 is officially live on Bitcoin mainnet.
Bitcoin L1 now has smart contracts, programmability, and 6-byte tickers. ⚡️
The road ahead is full of new products, features, and airdrops. Stay tuned! 🪂✨
"BRC20, the simple yet historic token protocol on Bitcoin, is about to evolve into a full-fledged smart-contract ecosystem, with native Bitcoin settlement and security." - @bestinslotxyz
Very excited to share that BRC2.0 (aka the "programmable module") is set to be released by the Best In Slot team at block 909,969 (~August 14th)
For more information on BRC2.0, we hope you'll review the post below and connect with the Best In Slot team for future updates.
Additionally, we hope you'll share your enthusiasm for this upgrade with your BRC20 infrastructure providers—coordinated support across wallets, exchanges, etc. will be essential to ensure a smooth rollout and to unlock the full potential of BRC2.0 programmability.
The BTC All-In Summit concluded with a panel on Unlocking Bitcoin Stablecoins and Primitives.
Our panelists shared how Bitcoin trading is no longer just about BTC - stablecoins are coming to Bitcoin DeFi:

BITCOIN RAILS EPISODE #17: DOMO’S SIDE OF THE STORY & the HISTORY OF BRC20
A particularly special episode—@domodata sits down with me for his first video interview ever—to recount the unique history of the BRC20 protocol.
The first Bitcoin-native token standard ever created, BRC20 came into existence almost overnight and quickly emerged as a multibillion dollar asset class in 2024.
This episode covers the influences leading up to the birth of $ORDI, the roles of different players involved along the way, and how core maintainers are preparing for their next major update—affectionately dubbed “BRC 2.0” by Bitcoin educator @bobbodily
Additionally, Domo shares his memory of key moments in BRC20 history—including:
—the development of BRC20's canonical indexer and details of Domo's working relationship with @unisat_wallet
—Ordi's listing on OKX and Binance (+ what he believes triggered listing decisions by those exchanges)
—the creation of the Layer 1 Foundation and the responsibilities of its member organizations in maintaining the core protocol
—why Domo has never accepted funding (including advisory fees) from either of his lead maintainer companies @unisat_wallet or @bestinslotxyz
We also go into depth about what sparked the “BRC20 indexer wars” and how stakeholders are ensuring the integrity of its consensus going forward.
This episode includes special mentions of major influences in the evolution of BRC20—including @redphone@robertjfclarke@Bitcoin_Punks_@satsnames@bestinslot@unisat_wallet and others.
This episode can be viewed on YouTube or Spotify using the linktree in Isabel’s bio—YouTube episode is also in the comments.
As always, thanks to the show's sponsor @bestinslotxyz for making this episode possible— in addition to being a core maintainer of BRC20, Best In Slot maintains the leading API for Ordinals and BRC20 data aggregation and indexing.

BRC20 PROTOCOL UPDATE ▶️▶️
1. The BRC2.0 Programmable Module, developed by the @bestinslotxyz team, will be available on Bitcoin Signet this Monday, March 31st.
This upgrade introduces a virtual machine and Turing-complete functionality into the BRC20 canonical indexer—enabling BRC20 tokens to become programmable.
Documentation and tooling will be available for developers interested in building DeFi and other applications with the BRC20 standard on Bitcoin L1, without relying on bridges, multi-sig schemes, L2s, or validator networks
For more information about the BRC2.0 Programmable Module, follow the @bestinslotxyz team for updates and Q&A.
2. The @unisat_wallet team has developed three implementations for a BRC20 single-step transfer function—for three indexing service providers, including OKX, UniSat and OPI. The team intends to publish its implementation proposal by the end of this week.
Additionally, UniSat will be facilitating testing of this function in various environments—including on the @fractal_bitcoin network.
For updates on testing of the BRC20 single-step transfer function implementation—follow @unisat_wallet
3. As of today, the @unisat_wallet team is including two additional implementations of the BRC20 swap module on the @fractal_bitcoin network, after its initial implementation was introduced in September 2024.
Over the next 2–4 weeks, these new implementations will be rigorously tested to ensure their stability and reliability—in preparation for activation on Bitcoin mainnet.

All teams involved with the development of BRC20 appreciate any and all feedback on code, docs, etc. as these updates are implemented. We're thrilled to push the BRC20 core protocol forward throughout 2025!
🛡️ Rebar Shield is now operational on Bitcoin, providing private mempool orderflow for users transacting on Bitcoin.
Shield protects users from current sniping strategies on Bitcoin meta protocols and will be an essential piece of infrastructure for MEV protection as it emerges alongside the developing Bitcoin DeFi ecosystem.
During our soft launch period multiple test transactions were added to blocks. Now, we turn to:
--Integrations with apps and meta protocols that bring digital assets and DeFi on-chain to Bitcoin.
--Increasing the amount of hashrate accessible, which will in turn make Shield transactions finalize faster.
If you’re interested in supporting Shield, please reach out to us by visiting https://t.co/EG0FkRSrdO!
