In the context of increasing emphasis on compliance, security, and trust in Web3 infrastructure, Japan has become the next strategic high ground for the global cryptocurrency industry. As one of the most influential crypto events in Asia, IVS Crypto Japan 2025 successfully concluded last week in Kyoto, attracting over a hundred projects and thousands of practitioners.

At this conference, regarded as the "Crypto Davos of Asia," the infrastructure project NexVault, focused on Web3 asset self-custody and family inheritance, emerged as one of the most attention-grabbing enterprise-level solution providers.

Can "inheritance" also be on-chain? We saw a new trust logic in Japan

In front of NexVault's booth, many attendees pondered for the first time: If my crypto assets need to be inherited one day, how can I ensure that the assets won't be lost and won't be easily stolen?

We showcased NexVault's "self-custody multi-signature inheritance mechanism," which allows users to manage enterprise or family assets securely and ensure long-term inheritance without relying on CEX or third-party verification, making on-chain assets truly controllable, transferable, and uninterrupted.

During this exhibition, we highlighted two types of solution scenarios:

• High-net-worth families: Multi-signature inheritance allows estate planning to no longer rely on traditional legal paths;

• Enterprise multi-signature collaboration: Prevents issues such as employee resignation, loss of contact, or key loss from causing permanent asset freezing.

Real feedback from overseas Web3 projects: "We have needed such a tool for a long time"

Over three days of discussions, we hosted project teams and investors from Singapore, Japan, South Korea, Hong Kong, the United States, and other countries/regions, who generally focused on:

• How to achieve "emergency recovery" in a "non-custodial" manner?

• Does it support integration with systems like Gnosis?

The multiple stages of inheritance methods we provided, "multi-signature inheritance + conditional inheritance + legal compatibility support," received high recognition.

Many teams scheduled follow-up product demos on the spot and expressed their desire to integrate NexVault into their asset account systems.

Why NexVault? We focus on certainty in "moments of loss of control"

NexVault consistently adheres to the design philosophy of "preventing loss of control and ensuring inheritance." This is not a wallet product, nor a CEX alternative, but rather a:

"Last mile infrastructure" for Web3 asset custody and inheritance

We address the following issues:

• If the asset private key is lost, is there a "verifiable" recovery method?

• If family asset planning is cross-border, can a delayed release or trigger mechanism be designed?

• If a business operator suddenly goes missing, how can the legal rights of employees and shareholders be protected?

All of these can be resolved through NexVault's conditional logic, on-chain signatures, and permission strategies.

Where will we go next?

With the conclusion of IVS, we have begun in-depth discussions with several Japanese manufacturers and cross-border family offices. NexVault will launch more versions of "inheritance templates," "enterprise recovery logic," and "cross-border asset allocation solutions" in Q3 2025, and will continue to participate in:

• WebX Tokyo (August)

• Bitcoin2025 HK (August)

• Multiple overseas private exchange dinners (Shenzhen, Hangzhou, Chengdu, etc.)

We hope to be present where safety is truly needed, not just at the peak of market enthusiasm.
