BRC2.0 Arrives in Q1 2025 on Bitcoin Testnet
As co-lead maintainers of the BRC20 protocol, we’ve invested significant resources to evolve BRC20 into the most expressive native token standard on Bitcoin—meeting the needs of all token issuers, from corporate players to dApp builders to degens around the world.
While much of our work last year was behind the scenes, 2025 opens the door to a new chapter defined by openness, co-creation, and meaningful progress.
Diving right in, we’re confident in sharing that Best in Slot, in coordination with the Layer 1 Foundation, will deliver BRC2.0 on testnet in Q1 2025.
BRC2.0, also known as the “BRC20 Programmable Module,” will enable smart contract functionality for all BRC20 tokens. This upgrade to the BRC20 core protocol unlocks infinite new use cases for native-assets on Bitcoin—including seamless DeFi, RWAs, DAOs, stablecoins and more, without relying on multisig bridges or L2s.
Due to BRC20's decentralized nature, the mainnet upgrade for this module will require significant coordination across the ecosystem. As such, we are targeting Q3 2025 for mainnet release of this module - and look forward to working with builders during the testnet phase to support the development of the BRC20 ecosystem leading up to its release.
We recognize the importance of broader web3 developer participation in the Bitcoin ecosystem and are committed to ensuring that building with BRC2.0 is seamless and straightforward.
To support this mission, we will deliver the following in 2025:
- Specification sheet for BRC2.0
- 100% Open-source and easy-to-run indexer (@opindexer)
- Plug and play BRC2.0 adaptor for proprietary BRC20 indexers
- Comprehensive documentation for developers
- BRC2.0 test suite for developers
- BRC2.0 explorer
- Tools for inscribing and interacting with smart contracts
- Free APIs for quick & easy experimentation
In parallel, @OKX and @Unisat have been working on an open-source implementation of the BRC20 swap module. As collaborating members of the Layer 1 Foundation, we are actively reviewing this implementation as they develop it to ensure everyone has open access to a powerful and robust indexer at launch. You can review our collective progress and contribute via GitHub here: https://github.com/bestinslot-xyz/OPI/pull/58
Lastly, we look forward to sharing more educational content about these upgrades - including development updates, accessible explainers, and answers to key questions from the community.
