BRC20 Phase 2 Activates at Block 934,888 (~ January 28th, 2026)
The BRC20 Phase II upgrade will activate at Bitcoin block height 934888, approximately on January 28, 2026. This activation expands BRC2.0 beyond the 6-character limit and enables programmability for all 4-5 character BRC20 tokens, such as $ORDI and $SATS.
Reaching this big milestone involved significant time and technical alignment between lead maintainers Best in Slot and UniSat, alongside key ecosystem partners including OKX and others. Coordinating independent implementations takes much more effort than using a single codebase, however, this approach allows the protocol to run reliably across different systems and keeps it decentralized and robust.
With this alignment complete, BRC20 now stands as a mature foundation for more sophisticated applications, including RWA tokenization and DeFi, secured by Bitcoin blockchain and unlocking a native economic application ecosystem on the network itself. Also with the EVM compatibility, teams can ship applications on Bitcoin using the tooling they already know, reducing build time, and easing integrations.
Action Required for Infrastructure and Service Providers
If you operate or utilize independent indexing infrastructure, ensure your systems match the canonical Open Protocol Indexer (OPI) data, or upgrade to the latest OPI version. Services relying on UniSat or BiS APIs will be automatically upgraded with no action required.
As part of the 2.0 update, the existing swap module on Bitcoin Mainnet will be closed and all balances will be refunded. Further details will be shared in a separate announcement.

As lead maintainers, we will continue to steward BRC20 as it enters its next major chapter, alongside the growth of builders, applications, and communities across the Bitcoin ecosystem.
