Hedera contributes Hashgraph-developed CLPR to LFDT
The bridgeless Cross-Ledger Protocol joins LFDT Labs as an openly developed codebase.

On 24 September 2026, Hedera contributed CLPR (“clipper”) to LF Decentralized Trust as a new lab. CLPR was developed by the Hashgraph team. It is a bridgeless cross-ledger messaging protocol: it uses state proofs so that independent ledger networks can verify each other’s state directly, with no intermediaries.
Used with an application built on it, CLPR can let assets, data and messages move across ledgers without bridges, pooled liquidity or intermediary validator networks.
Cross ledger interoperability is key to unlocking the flow of value across networks and platforms. 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
As an LFDT lab, CLPR is now an openly developed codebase. The specification (opens in a new tab), the Solidity contracts (opens in a new tab) for EVM ledgers, the Java endpoint (opens in a new tab) and the lab’s governance are in the LFDT-CLPR organization (opens in a new tab) on GitHub. Labs are where early work builds a community and invites contributions before it can become a top-level LFDT project, and CLPR is early: the specification is still changing and some economic parameters are open.
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 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.
