Quick answer: CLPR (pronounced “clipper”) is Hashgraph’s Cross-Ledger Protocol, a bridgeless way to move tokens, data, and messages between independent blockchain networks. It uses cryptographic state proofs instead of asset bridges or pooled liquidity, so no intermediary ever holds custody of what is being transferred. Hashgraph announced it at HederaCon in Miami on May 4, 2026, and it is currently in closed beta with an Early Adopter Program for institutions.

Moving value between separate blockchains has long depended on bridges, and bridges have been the single most exploited part of crypto infrastructure. They pool locked assets and lean on a small set of validators, which creates a concentrated target. CLPR is Hashgraph’s attempt to remove that target entirely. This piece walks through what the protocol actually does, what stage it is at, and what to watch before treating it as production infrastructure.
What CLPR is
CLPR stands for Cross-Ledger Protocol. According to the official CLPR page, it enables cryptographically secured communication and token transfers between independent networks without bridges, pooled liquidity, or an intermediary validator network. It handles more than tokens: data feeds and messages can cross ledgers the same way, which is what makes it a general connectivity layer rather than a single-purpose asset bridge.
The design detail that matters is custody. In a traditional bridge, assets are locked in a contract on one chain while a wrapped version is minted on another, and that locked pool is what attackers go after. CLPR endpoints never take custody. As co-founder Dr. Leemon Baird put it in the HederaCon announcement, the protocol replaces the need for bridges with a model built on cryptographic proofs rather than new trust layers.
How it works
The Hashgraph technical write-up describes a two-phase rollout:
- Phase 1: Dedicated CLPR endpoints sit on each ledger and exchange cryptographic proofs to verify and settle transfers. These endpoints never hold assets. If one goes offline, any party can resume a transfer by submitting the required proofs directly, so there is no single operator to trust.
- Phase 2: The validators of each network become the endpoints themselves, verifying each other’s state natively with no separate infrastructure. This is where the model gets closest to the ledgers verifying one another directly.
Crucially, the protocol is meant to preserve each participating ledger’s own security assumptions rather than introduce a new one on top. Trust in a shared intermediary is swapped for math that both sides can check.
Which networks it connects
The initial deployment links HashSphere, Hashgraph’s private permissioned networks, with the public Hedera network, supporting Sphere-to-Sphere and Sphere-to-Hedera transfers. Hashgraph describes CLPR as chain-agnostic and designed to extend to major EVM-compatible networks including Ethereum, Hyperledger Besu, and Avalanche subnets. Those broader connections are described as future targets, not shipped features.
Where it sits in the HederaCon news
CLPR was one of three announcements Hashgraph made at HederaCon. The other two were the general availability of HashSphere, the private permissioned network CLPR is built to connect, and a strategic investment in Madrid-based fintech ioBuilders, whose Asseto tokenization platform is set to integrate HashSphere. In the same announcement, CEO Eric Piscini framed the pitch to banks directly, arguing that financial institutions should not have to choose between regulatory compliance and access to new liquidity. HashSphere is also cited as supporting Australia’s Reserve Bank Project Acacia, a wholesale settlement pilot.
Why this matters
For institutions, the appeal is narrow and specific: run a private network for compliance and control, but still reach public liquidity without wrapping assets through a bridge that could be drained. That is the same interoperability problem central banks and settlement bodies keep flagging as the gating issue for tokenized finance. The Bank for International Settlements has argued that the value of tokenization depends heavily on whether tokenized assets can move across systems rather than sit in walled gardens (see the BIS work on tokenization and the monetary system). CLPR is one attempt to answer that at the protocol level.
The honest caveat is timing. CLPR is in closed beta, the second phase where validators verify each other is future work, and connections beyond HashSphere and Hedera are roadmap items. Announced capability is not the same as production adoption, and nothing here should be read as an endorsement of any token or investment. Treat the launch as a real design milestone worth tracking, not as finished infrastructure.
Common questions
What does CLPR stand for?
CLPR stands for Cross-Ledger Protocol and is pronounced “clipper.” It is Hashgraph’s bridgeless standard for moving tokens, data, and messages between independent blockchain networks.
How is CLPR different from a blockchain bridge?
A traditional bridge locks assets in a pool and relies on a small validator set, which creates a concentrated target for attacks. CLPR endpoints never hold custody of assets and instead exchange cryptographic state proofs, so there is no locked pool or intermediary validator network to compromise.
Which networks does CLPR connect?
The first deployment connects HashSphere private networks with the public Hedera network. Hashgraph describes the protocol as chain-agnostic and designed to extend to EVM-compatible networks such as Ethereum, Hyperledger Besu, and Avalanche subnets, though those connections are future targets.
Is CLPR live for the public to use?
Not yet. As of the May 2026 HederaCon announcement, CLPR is in closed beta with a selective Early Adopter Program for institutions. The phase where validators themselves act as endpoints is still future work.
When was CLPR announced?
Hashgraph unveiled CLPR on May 4, 2026, at HederaCon in Miami, alongside the general availability of HashSphere and a strategic investment in fintech firm ioBuilders.
