OtterSec is a blockchain security company known for smart contract audits. The OtterSec lawsuit does not involve a failed audit, crypto hack, or customer loss. It is mainly an internal business dispute about company ownership, contracts, assets, and fiduciary duties.
The main case is Li Fen Yao v. Robert Chen et al., Civil Action No. TDC-23-0889. Li Fen Yao filed it as administrator of the estate of her late husband, Sam Mingsan Chen. The defendants are Robert Chen, Otter Audits LLC, and RC Security LLC.
The case began in the Maryland federal court in March 2023. Some claims were dismissed in January 2025, but other important claims survived. Court activity continued into May 2026, so the dispute has not reached a final judgment.

Who Created OtterSec?
Robert Chen and David Chen met through cybersecurity competitions when they were teenagers. They later developed the plan for a blockchain security company that would audit software and smart contracts.
OtterSec LLC was formally established in Wyoming on February 8, 2022. Robert was 19, and David was 16 at the time. Since David was a minor, his father, Sam Chen, became the legal co-owner of the company on David’s behalf.
The original operating agreement gave Robert Chen and Sam Chen equal 50% interests. Robert and Sam were the official members of the LLC, but David played an important role in its technical work and operations.
According to allegations described in the court record, OtterSec earned more than $1 million during its first two months. The company hired employees and consultants and gained attention in the blockchain security market.
How the Ownership Structure Changed
Tension developed between Robert and David over David’s available time and role in the company. David was still in high school and could not devote all his time to OtterSec. On April 16, 2022, Sam and Robert signed an amended operating agreement. Sam transferred 10% of his interest to Robert. The change gave Robert a 60% ownership interest and left Sam with 40%.
This transfer later became an important part of the lawsuit. The estate alleges that Robert did not disclose important discussions with Jump Trading and Jump Crypto before Sam agreed to transfer the additional 10%. Robert disputes the allegations against him. The court has not made a final finding that he committed fraud or breached his duties.
Jump Crypto Negotiations
The complaint alleges that Robert participated in discussions about a possible acquisition or “acquihire” involving Jump. An acquihire usually focuses on hiring a company’s team rather than buying all its products and assets.
The estate claims Robert knew about these discussions when Sam transferred part of his ownership. It also claims Sam may not have accepted the new agreement if he had received complete information.
The court later found that some allegations connected to these discussions were legally sufficient to continue beyond the pleadings stage. This does not mean the estate has proven its case. It only means those issues were not dismissed at that stage.
The Dissolution Dispute Began Before Sam’s Death
The previous version of this article incorrectly stated that Sam’s death started the dissolution conflict. Court records show that Robert had already discussed dissolving OtterSec before Sam died.
In May 2022, Robert allegedly told David that he might dissolve the company and create it again if Sam refused to sell his remaining interest. An attorney acting for OtterSec later informed Sam and David that Robert planned to dissolve the company.
Sam and David hired legal counsel and challenged Robert’s claimed authority to act alone. Sam died in a car accident on July 13, 2022, before the dispute was resolved. Li Fen Yao was Sam’s wife, not his mother. She was later appointed administrator of his estate. She is also David Chen’s mother.
What Did the Court Decide About OtterSec’s Dissolution?
The amended operating agreement stated that OtterSec would dissolve after the death of a member. Sam Chen died on July 13, 2022. In its January 2025 opinion, the court concluded that OtterSec automatically dissolved on that date.
On August 15, 2022, Robert Chen executed a Second Amendment that removed death as a dissolution event and stated that the company would continue perpetually. However, the court found that OtterSec had already dissolved under the agreement before that amendment was signed.
This finding did not end the entire case. The court allowed contract claims based on Robert’s alleged statements before Sam’s death and his alleged conduct during the company’s winding-up period to continue.
New Companies and the OtterSec Asset Auction
Robert formed Otter Audits LLC and RC Security LLC on September 13, 2022. He is identified in the court record as the sole member of both companies. Robert stated in a formal declaration that OtterSec’s assets were offered through a publicized auction on September 24, 2022. He said he was the highest bidder and paid $210,000.
The assets reportedly included:
- OtterSec trademarks and logos
- The
osec.iodomain - The company website
- Social media accounts
- Computer code and equipment
- Other intellectual property
Robert later transferred or contributed assets to RC Security, which licensed intellectual property to Otter Audits. The estate disputes aspects of this process and the handling of Sam’s ownership interest. These remain disputed matters. They should not be presented as proven misconduct unless a court reaches that conclusion.
Claims Filed by Sam Chen’s Estate
Li Fen Yao filed the main federal lawsuit on March 31, 2023. The complaint originally included claims involving:
- Breach of contract
- Breach of fiduciary duty
- Fraud
- Lanham Act violations
- Misappropriation and conversion
- Tortious interference
- Successor liability
The estate requested financial damages and other relief. It also sought an accounting of relevant business activity and declarations concerning the parties’ legal rights. The defendants denied liability and asked the court to dismiss different parts of the case.
The March 2024 Jurisdiction Decision
The defendants first argued that the Maryland court lacked personal jurisdiction over them. Judge Theodore D. Chuang rejected that argument on March 11, 2024.
The court found enough connections between the dispute and Maryland to allow the case to continue there. This decision addressed jurisdiction only. It did not decide whether the estate’s allegations were true.
What the Court Decided in January 2025
On January 27, 2025, the court granted part of the defendants’ motion for judgment on the pleadings and denied another part. The court dismissed the Lanham Act claim. However, the claim was not dismissed merely because the OTTERSEC name was unregistered.
The court found that the alleged trademark injury belonged directly to OtterSec LLC. That type of injury needed to be pursued as a derivative claim on behalf of the company. The estate had not brought it in the required form.
The court also dismissed certain fiduciary-duty allegations and the misappropriation, conversion, and tortious-interference claims. Some of these claims concerned injuries allegedly suffered by OtterSec rather than direct injuries to Sam or his estate.
Other parts of the case survived. These included certain claims involving Robert’s alleged duties to Sam, the ownership transfer, the operating agreement, fraud, and the handling of the company’s dissolution. The January 2025 decision was not a final verdict. It decided which claims could continue based on the pleadings.
The Related Case Against David Chen
Robert Chen filed a separate lawsuit against David Chen in the Wyoming federal court in September 2024. OtterSec LLC was later added as a plaintiff. The complaint alleges that David removed company code and misappropriated trade secrets.
It also alleges that he took approximately $23,868 in cryptocurrency tokens from an OtterSec wallet in February 2024. David has disputed those accusations. No final ruling establishing that he stole code or cryptocurrency has been identified.
The article previously stated that the Wyoming court had not ruled on David’s transfer request. That information is outdated. On December 16, 2024, the court ordered the case transferred to Maryland. The related case is now listed as Chen et al. v. Chen, Case No. 8:24-cv-03628, in the U.S. District Court for the District of Maryland.
The OtterSec.io Domain Dispute
A separate administrative proceeding concerned the ottersec.io domain. This was not the same as the main Maryland lawsuit. Robert Chen, OtterSec LLC, Otter Audits LLC, and RC Security LLC filed a complaint through the World Intellectual Property Organization. The respondent did not submit a response to the complaint.
On July 14, 2025, the WIPO panel found that the complainants had rights in the unregistered OTTERSEC mark. It also found bad-faith registration under the applicable domain dispute policy.
The panel ordered the The ottersec.io domain transferred to RC Security LLC. This proceeding concerned the domain name. It did not resolve all ownership and contract claims in the federal lawsuit.
Current Status of the OtterSec Lawsuit
The statement that the main case has remained paused since June 2024 is no longer accurate. Court records show later discovery activity. A related subpoena dispute was filed in Arizona because the estate sought financial records from a non-party located there. On May 22, 2026, the Arizona federal court granted Li Fen Yao’s motion to compel compliance with the subpoena.
This activity shows that the discovery connected with the Maryland lawsuit continued into 2026. No final trial judgment or publicly confirmed settlement has been identified as of June 2026. The allegations that survived dismissal still need evidence and further court review. A settlement also remains possible before trial.
Does the Lawsuit Concern a Failed Crypto Audit?
No verified court record shows that the main OtterSec lawsuit arose because the company missed a smart contract vulnerability or caused a customer to lose cryptocurrency. The dispute concerns the internal affairs of OtterSec, including ownership, disclosure of business negotiations, dissolution, company assets, and the rights of Sam Chen’s estate. Claims that a client sued OtterSec over a defective audit should not be included without a separate verified complaint and case number.
What Startup Founders Can Learn
The case shows why founders need a detailed operating agreement. The agreement should explain what happens after a member dies, becomes unable to work, wants to sell an interest, or leaves the company.
Founders should also document ownership of source code, domains, wallets, trademarks, and social media accounts. Major investment or acquisition discussions should be recorded and shared with anyone who has a legal right to receive that information.
The dispute also shows that an unregistered trademark may still receive some legal protection. However, ownership and the correct legal procedure remain important. Registering a valuable mark can still provide clearer evidence and stronger enforcement options.
Conclusion
The OtterSec lawsuit is an ongoing business dispute, not a case about a failed blockchain audit. It concerns the dissolution of OtterSec LLC, the transfer of company assets, alleged undisclosed acquisition discussions, and the rights of Sam Chen’s estate.
The court dismissed several claims in January 2025 but allowed other important issues to continue. The related case against David Chen was transferred from Wyoming to Maryland, and WIPO resolved the separate ottersec.io domain dispute in July 2025.
Discovery activity continued into May 2026. No final ruling has established full liability against Robert Chen, David Chen, Otter Audits, or RC Security. Until the court issues a final decision, all unresolved accusations should be clearly described as allegations.
