Citrea launched its mainnet on January 27, bringing a programmable application environment, the bridged bitcoin asset cBTC and the ctUSD stablecoin into one ecosystem. The project wants developers to build trading and other financial applications around bitcoin. Its launch announcement also identifies services that remain planned, so the live network should not be confused with a completed product roadmap.
In its mainnet announcement, Citrea describes cBTC as the asset used to move bitcoin value into its application layer. The bridge behind it, Clementine, uses BitVM and zero-knowledge technology.
The bridge carries its own assumptions
Citrea says Clementine uses optimistic verification: fraudulent bridge activity can be challenged on Bitcoin. Its stated security model assumes at least one honest bridge signer. That condition belongs alongside the project’s description of the bridge as trust-minimized.
For a user, the practical distinction is between holding bitcoin on its base network and using a representation of that value in an application environment. The latter adds bridge mechanics and application contracts to the transaction path. A familiar asset name does not make those systems interchangeable.
The launch material points users to a bridge hub and a dashboard for discovering applications. Before moving funds, a user needs to understand the route back as well as the route in.
ctUSD supplies a separate dollar asset
The ecosystem also includes ctUSD, issued by MoonPay and powered by M0’s stablecoin infrastructure. Citrea positions it as a common dollar asset for trading and settlement within the network.
ctUSD and cBTC have different purposes. One represents a dollar-denominated token; the other connects bitcoin to the programmable layer. Their operation and dependencies should be evaluated separately.
Citrea lists decentralized exchanges among the launch destinations while marking some lending, privacy and prediction-market applications as coming later. The announcement is therefore evidence of a mainnet launch, not proof that every proposed service is already usable or that liquidity is deep enough for every transaction.
