Bitcoin Layer 2 project Citrea has announced the launch of its ctUSD Pre-Deposit Vault, backed by more than $50 million in liquidity commitments from institutional asset managers, including Galaxy Digital. The vault is scheduled to open for deposits on May 7 at 3:00 PM UTC, with an initial deposit limit of $15 million.
How the safe works
The liquidity provided by Galaxy Digital and other partners will be provided outside the vault in the form of Citrea’s own assets, cBTC and ctUSD. These funds will be deployed through decentralized finance (DeFi) protocols, including Morpho and Zentra Finance credit markets, as well as decentralized exchanges (DEXs) and cBTC-based structured return products. This structure aims to create a fluid, return-generating ecosystem around Citrea’s Bitcoin-centric Layer 2 infrastructure.
Deposit terms and incentives
Investors who participate in the vault can deposit on an Ethereum basis $USDC. Deposits are subject to a two-month lock-up period, during which the money cannot be withdrawn. In exchange for deploying capital, savers receive an additional reward equal to 0.6% of the total CTR token supply. This incentive is intended to attract early liquidity providers and kick-start the ctUSD ecosystem.
Why this matters for Bitcoin DeFi
Citrea operates as a zero-knowledge (ZK) rollup on Bitcoin, aiming to bring scalable smart contract functionality to the Bitcoin network without compromising the security model. The launch of a dedicated ctUSD vault with significant institutional support signals growing confidence in Bitcoin-based DeFi, also known as BTCFi. The involvement of Galaxy Digital, a major digital asset management company, adds credibility to the project’s liquidity strategy.
Timeline and next steps
The vault will accept deposits from May 7. After the two-month lock-up period expires, savers will be able to access their rewards and any returns generated through the vault’s DeFi allocations. Citrea has not yet announced a specific date for the distribution of CTR token rewards, but the 0.6% allocation represents a fixed portion of the total token supply.
Conclusion
Citrea’s ctUSD Pre-Deposit Vault represents a structured effort to build liquidity for its Bitcoin Layer 2 ecosystem. With institutional support and a clear incentive mechanism, the project positions itself within the growing BTCFi sector. Investors should carefully consider the two-month lock-up period and inherent risks of DeFi protocols before participating.
