Blockchain networks today largely operate as distinct ecosystems. Each one maintains its own consensus rules, token standards, and execution environment. As a result, assets issued on one ledger are generally unable to interact natively with another. Workarounds such as bridges and wrapped assets have emerged to address this fragmentation. However, these workarounds can introduce additional security risks, intermediaries, and liquidity requirements. CLPR aims to address these challenges with a new approach to cross-ledger interoperability.
The stakes behind that fragmentation are significant. Bridge exploits have caused more than $2.8 billion in cumulative losses since 2022. That figure represents over 69% of all funds DeFi protocols lost in that span. The Ronin Bridge hack alone cost $624 million in March 2022. BNB Bridge lost $568 million later that year. Attackers drained Wormhole of $326 million months earlier still. Even in 2026, the pattern continues. Industry trackers estimate bridge incidents have cost roughly $329 million across eight attacks this year alone. Against that backdrop, Hedera’s contribution lands at a moment when cross-ledger risk sits squarely in focus.
Bridgeless by Design
Bridgeless by design, CLPR uses state proofs to let ledgers verify each other’s states directly. No intermediaries sit in between. Rather than working around liquidity fragmentation with bridges and relayers, CLPR aims to end what Hashgraph calls the “trapped liquidity era” altogether. It establishes cryptographic trust directly between ledgers. As a result, CLPR-enabled applications can move tokens, data, and messages freely and securely across networks, without a bridge.
Daniela Barbosa, General Manager of Decentralized Technologies at the Linux Foundation and Executive Director of LF Decentralized Trust, welcomed the contribution. “Cross ledger interoperability is key to unlocking the flow of value across networks and platforms,” Barbosa said. “As a new LFDT lab, CLPR will leverage open development to shape a protocol that fuels collaboration across the industry. With this contribution, Hedera is once again showing its commitment to vendor neutral, collaborative development of critical shared technologies.”
An Openly Developed Codebase
Now, as an LFDT lab, CLPR becomes an openly developed codebase. Developers can experiment with the CLPR codebase in the LFDT Labs GitHub repository and explore different use cases. This gives the project a structured path to grow. LFDT Labs enables participants to refine this early-stage work by building a community, inviting contributions, and establishing momentum, before a project reaches top-level LFDT project status.
Dr. Leemon Baird, Co-Founder at Hedera and Chief Scientist at Hashgraph, tied the contribution to Hedera’s broader open-source history. “Just weeks ago marked the two-year anniversary of Hedera’s establishment as a founding Premier Member of the Linux Foundation Decentralized Trust, donating the entirety of the Hedera codebase to LFDT as Project Hiero,” Baird said. “That commitment to open collaboration is exactly what’s needed to solve one of the industry’s most persistent problems: network interoperability. When underpinning an application, CLPR is designed to fix that cryptographically so data, assets and messages move freely without a single point of failure to attack. Today’s announcement that Hedera is donating another protocol to LFDT shows that our commitment is only growing, and we’re excited to see how developers experiment with CLPR’s capabilities.”

The Cross-Ledger Early Adopter Program
The contribution of CLPR to the LFDT ecosystem coincides with a call for participants to join Hashgraph’s Cross-Ledger Early Adopter Program. Involvement is welcomed from financial institutions, fintechs, asset issuers, liquidity providers, and corporations. The program is structured around three distinct use cases: cross-border payments and in-flight FX, cross-ledger settlement, and collateral mobility.
This three-phased virtual program offers full access to a Hashgraph-hosted testnet environment. There, participants can move real test assets safely using a CLPR-enabled application layer. Technical participants also have access to an assigned integration expert to support their progress. The program aims to select participants from a range of countries. That approach bakes in cross-border regulatory and compliance considerations from the beginning. Organizations can register interest at hashgraph.com/clpr-early-adopter-program ahead of the program’s full market launch.
What This Means Going Forward
CLPR’s arrival at LFDT gives the protocol a different growth path than a typical corporate rollout. By opening the codebase rather than keeping it proprietary, Hedera and Hashgraph are betting that outside contribution will strengthen CLPR faster than closed development could. That bet mirrors the path Hiero already walked, moving from a 2024 contribution toward graduated LFDT project status over two years.
Even so, CLPR’s real-world impact remains unproven. The protocol is still early, and the Cross-Ledger Early Adopter Program exists precisely to test it under real conditions before a full market launch. Developers reviewing the LFDT Labs GitHub repository and institutions joining the testnet will shape what CLPR becomes next.
