- Code Contribution to facilitate developer participation and experimentation with the new bridgeless cross-ledger protocol
- Hashgraph is also calling for participants to join the Cross-Ledger Early Adopter Program, which offers full access to a Hashgraph-hosted testnet environment for selected participants
24 September 2026 – Hedera has contributed CLPR (pronounced “clipper”), the bridgeless Cross-Ledger Protocol in development by Hashgraph, to Linux Foundation Decentralized Trust (LFDT) as a new lab.
Blockchain networks today largely operate as distinct ecosystems — each with its own consensus rules, token standards and execution environment. 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, but can introduce additional security risks, intermediaries and liquidity requirements. CLPR aims to address these challenges with a new approach to cross-ledger interoperability and, through LFDT Labs, is inviting the broader open-source developer community to help shape, test and advance the protocol.
“Cross-ledger interoperability is key to unlocking the flow of value across networks and platforms,” said Daniela Barbosa, General Manager, Decentralized Technologies, Linux Foundation, and Executive Director, LF Decentralized Trust. “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.”
Bridgeless by design, CLPR uses state proofs to allow ledgers to verify each other’s states directly, with no intermediaries in between. Rather than working around the liquidity fragmentation problem with bridges and relayers, CLPR aims to end the “trapped liquidity era” altogether. It establishes cryptographic trust directly between ledgers so CLPR-enabled applications can move tokens, data, and messages freely and securely across networks without a bridge.
Now, as a 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, said: “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. 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 contributing 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 contribution of CLPR to the LFDT ecosystem coincides with a call-out 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 to focus on three distinct use cases: Cross-border payments and in-flight FX, cross-ledger settlement, and collateral mobility. This 3-phased virtual program offers full access to a Hashgraph-hosted testnet environment, where participants can move real test assets safely using a CLPR-enabled application layer. Technical participants will also have access to an assigned integration expert to support their progress. The program aims to select participants from a range of countries in order to bake in cross-border regulatory and compliance considerations from the beginning.
