A new Hedera Exponential Science lawsuit is putting one of the network’s grant relationships under sharp legal scrutiny, with Hedera Hashgraph, LLC accusing affiliated Exponential Science entities of holding back unspent funds and shifting assets out of reach after a grant deal was terminated.
The case was filed in New York County Supreme Court on May 15, 2026, under Index No. 652870/2026. Hedera named four defendants: Exponential Science Foundation (Cayman Islands), Exponential Science Capital (Cayman Islands), Exponential Science OpCo (Cayman Islands), and Exponential Science Foundation (Switzerland).
At the center of the dispute is money meant to support research, education, and innovation programs tied to the Hedera ecosystem. What began as a major $HBAR-funded partnership has now become a New York breach of contract battle involving tens of millions of dollars, a request for a full accounting, and demands for injunctive and declaratory relief.
What Hedera says went wrong in the $HBAR grant dispute
Hedera’s complaint says the dispute stems from a grant agreement signed on August 14, 2022. Under that deal, Hedera provided funding for programs designed to help promote and grow the Hedera ecosystem.
The filing says Hedera initially committed $12,753,333 worth of $HBAR and that the arrangement could ultimately reach up to $161,860,000 worth of $HBAR. A later amendment, dated September 5, 2024, authorized another $33,800,000 worth of $HBAR.
According to the complaint, Hedera exercised its contractual termination right on February 25, 2026, with the termination taking effect on May 26, 2026. Hedera says the agreement required Exponential Science Foundation (Cayman Islands), or ESF Cayman, to promptly transfer any uncommitted or unspent grant funds back after termination.
Instead, Hedera alleges ESF Cayman refused to return the unspent grant funds.
That point matters because the complaint frames the issue as more than a routine contract dispute. Hedera says the money was not ordinary corporate capital, but grant funding intended for defined ecosystem programs tied to the Hedera public distributed ledger and funded in $HBAR.
The grant relationship and termination terms
The legal filing traces the relationship back to a request-for-proposals process in which Hedera selected the DLT Science Foundation and its related structure as a grant recipient. The agreement was originally signed with DSF OpCo, Ltd., and later assigned to ESF Cayman in June 2024.
Hedera says the grant terms allowed it to terminate the arrangement with 90 days’ written notice “for any reason or no reason at all.” The complaint also says the contract’s termination section required the return of “Uncommitted Grant Funds.”
That contractual language is central to the case. Hedera argues that uncommitted funds included money not spent or not contractually committed to outside grantees, contractors, vendors, or service providers. It also says that obligation extended to funds moved among related entities covered by the agreement.
The complaint further says the grant agreement related to a transaction worth more than $1,000,000 and cites NY GOB § 5-1402. Hedera claims New York is the proper forum because the contract included New York choice-of-law, forum selection, and venue provisions, with New York County specifically designated as the venue.
Alleged asset transfers at the heart of the case
The most striking allegation in the Hedera Exponential Science lawsuit is Hedera’s claim that ESF Cayman transferred 98% of its assets to subsidiaries and affiliates.
According to the complaint, Hedera requested updated financials after sending its termination notice. It says financial records previously showed roughly $70.3 million worth of assets as of December 31, 2025, including $35.6 million worth of $HBAR tokens, $14.1 million worth of stablecoins, $2.9 million worth of other cryptocurrencies, and $17.7 million in fiat currencies.
But Hedera says a March 31, 2026 balance sheet later showed ESF Cayman’s assets had fallen to under $1 million. The complaint alleges that ESF Cayman explained it had transferred about $76 million worth of funds on October 20, 2025, including:
- $52.7 million worth of assets to ES Capital
- $19.9 million worth of assets to ES OpCo
- $3.4 million worth of assets to ESF Switzerland
Hedera alleges those transfers were made to affiliated entities in a way that would make ESF Cayman effectively judgment proof. The complaint also says ESF Cayman continued reporting consolidated results earlier in the relationship, but took a narrower entity-by-entity position once the grant was terminated.
That is a major business implication of the $HBAR grant dispute. If a court focuses on how grant funds moved between a foundation, subsidiaries, and affiliates, the case could influence how ecosystem treasuries, internal fund transfers, and multi-entity operating structures are documented in future crypto grant programs.
Why this case matters for crypto grant structures
This lawsuit lands in a part of the crypto industry that often gets less attention than token prices or exchange battles: grant administration.
Hedera’s complaint points to a familiar tension in digital asset ecosystems. Networks often distribute large pools of token-denominated funding to outside foundations or related operators to support adoption, research, and development. However, when those relationships break down, questions about who controls the assets, how they are tracked, and whether intercompany transfers preserve or change their legal character can become expensive very quickly.
In this case, the filing references $HBAR, stablecoins, other cryptocurrencies, and fiat balances. That mix adds another layer. The legal fight is not just about whether funding existed, but about where it sat, how it was classified, and whether moving it among related entities affected the obligation to return unspent grant funds.
The legal claims and relief Hedera is seeking
Hedera asserts four main claims in the complaint:
- breach of contract
- breach of the duty of good faith and fair dealing
- unjust enrichment
- declaratory judgment
The breach-based claims are aimed at ESF Cayman and, in some parts of the case, at ES Capital and ES OpCo. The unjust enrichment claim is pleaded against all defendants. Hedera also seeks a declaration that ES Capital and ES OpCo are liable as alter egos through which ESF Cayman allegedly engaged in wrongful conduct.
The complaint asks for damages in an amount to be determined at trial, but it expressly says the suit seeks tens of millions of dollars in money damages and, in the alternative, equitable relief.
Hedera is also asking the court to order a full accounting of all grant funds, including their locations, commitments, and expenditures. On top of that, the filing seeks preliminary and permanent injunctive relief to stop the defendants from spending, committing, pledging, or otherwise disposing of the disputed uncommitted grant funds.
Why New York venue matters in the Hedera Exponential Science lawsuit
The venue fight may sound technical, but it is one of the more important signals in the filing.
Hedera says the contract designated New York County as the venue and points to a contractual provision as the basis for bringing the case there. The complaint also says the deal falls under NY GOB § 5-1402 because it involves more than $1,000,000 and includes New York choice-of-law and forum clauses.
That matters because large crypto-related agreements frequently rely on traditional commercial law frameworks even when the underlying assets are tokens like $HBAR. The filing shows how disputes over digital asset grants can still be fought in a conventional state court setting, using standard contract doctrines such as forum selection, unjust enrichment, and declaratory judgment.
The broader governance question for Hedera ecosystem funding
For Hedera, the case is about recovering money it says should have come back after termination. But the Hedera Exponential Science lawsuit also raises a broader governance question for blockchain ecosystems that fund outside initiatives at scale.
The complaint describes a structure in which grant funds could be distributed across multiple related entities, including wholly owned subsidiaries and affiliates. Hedera now argues those transfers did not erase the duty to return unspent funds. If that reading gains traction in court, foundations and crypto-aligned operators may face tougher expectations around treasury segregation, internal transfer records, and the legal treatment of affiliated entities.
The filing references the Hedera public distributed ledger, $HBAR funding, and the network’s effort to grow its ecosystem through grants. That makes this more than a one-off vendor disagreement. It is a test of how token-based ecosystem funding holds up when a commercial relationship collapses and the paper trail becomes the real product under examination.
For now, the lawsuit places tens of millions of dollars, a cross-border foundation structure, and a major crypto ecosystem’s grant controls squarely before a New York judge.
