Today, Citrea announced the launch of the Citrea testnet on Bitcoin Testnet4. This marks a significant advancement in Bitcoin's role as a settlement layer, laying the foundation for a decentralized, self-sovereign financial ecosystem worldwide. Bitcoin has taken another step forward toward its next phase as the cornerstone of global finance.
The Citrea testnet ushers in a new era for Bitcoin, where users can leverage Bitcoin’s capabilities without compromising self-sovereignty. The Citrea testnet is currently the only available Rollup solution enabling EVM developers to build decentralized applications that inherit Bitcoin's security while using BTC in a trust-minimized manner.
What does the Citrea testnet include?
The Citrea testnet features an almost complete version of Clementine, Citrea’s trust-minimized bridge design based on BitVM, testing key bridge infrastructure components such as detecting malicious operators, coordinating pre-signatures, and operator-based withdrawals. The final piece—implementing fraud proofs via BitVM—is currently underway, with the team actively contributing to open-source BitVM repositories.
Building an Economy on Bitcoin
With the Citrea testnet, Bitcoin finally moves closer to its original vision: achieving self-sovereign finance. The Citrea testnet provides developers with an innovative platform to build powerful applications that bring financial inclusion and freedom to both new and existing Bitcoin users. By leveraging Bitcoin for settlement and data storage, Citrea enhances BTC’s utility and unlocks Bitcoin’s blockspace for a new financial ecosystem.
Key Features of Citrea:
-
Fully EVM-Compatible: Citrea’s execution environment supports all EVM tools and languages, allowing developers to easily deploy smart contracts on a platform secured by Bitcoin.
-
Bitcoin Settlement: With the full implementation of Clementine, Citrea’s trust-minimized BitVM bridge, developers can utilize trust-minimized BTC within their applications.
-
Access to Bitcoin Blockspace: Citrea opens up highly secure blockspace to developers, empowering them to build applications and create an economy secured by Bitcoin.

Citrea plans to launch its mainnet in Q1 2025.
