As Web3 infrastructure increasingly emphasizes compliance, security, and trustworthiness, Japan has become the next strategic high ground for the global crypto industry. As one of the most influential crypto events in Asia, IVS Crypto Japan 2025 successfully concluded in Kyoto last week, attracting more than 100 projects and thousands of practitioners to participate.
In this conference regarded as the Crypto Davos of Asia, NexVault, an infrastructure project focusing on Web3 asset self-custody and family inheritance, became one of the most popular enterprise-level solution providers on site.
Can “heritage” also be put on the chain? We have seen a new logic of trust in Japan
In front of the NexVault booth, many participants thought seriously for the first time: If my crypto assets need to be inherited one day, how can I ensure that the assets will not be lost or easily stolen?
We demonstrated the self-custodial multi-signature inheritance mechanism created by NexVault. By flexibly configuring signature permissions and recovery paths, users can complete the secure management and long-term inheritance of corporate or family assets without relying on CEX or third-party verification, making on-chain assets truly controllable, transferable, and uninterrupted.
In this exhibition, we focused on presenting two types of solution usage scenarios:
High net worth families: multi-signature inheritance, so that estate planning no longer relies on traditional legal paths;
Enterprise multi-signature collaboration: Prevents permanent freezing of assets due to issues such as employee resignation, loss of contact, and key loss.
Real feedback from overseas Web3 projects: We have needed such a tool for a long time
During the three-day exchange, we received project teams and investors from Singapore, Japan, South Korea, Hong Kong, the United States and other countries and regions . They generally paid attention to:
How to implement “emergency recovery” in a “non-custodial” form?
Does it support integration with systems such as Gnosis?
The multi-stage inheritance method we provide, multi-signature inheritance + conditional inheritance + legal compatibility support , has received extremely high recognition.
Many teams made appointments for subsequent product demos on the spot and expressed their hope to connect NexVault to their asset account systems.
Why NexVault? We focus on the certainty of out of control moments
NexVault always adheres to the design concept of preventing loss of control and ensuring inheritance. It is not a wallet product, nor a CEX substitute, but a:
The “last mile infrastructure” for Web3 asset custody and inheritance
We solve the following problems:
If the private key of an asset is lost, is there a “verifiable” way to recover it?
If family asset planning is cross-border, is it possible to design a delayed release or trigger mechanism?
If the business operator suddenly loses contact, how to protect the legal rights and interests of employees and shareholders?
All of these can be solved through NexVaults conditional logic, on-chain signatures, and permission policies.
Where will we go next?
With the end of IVS, we have begun in-depth exchanges with several Japanese manufacturers and multinational family offices. NexVault will launch more versions of Inheritance Templates, Enterprise Recovery Logic and Cross-border Asset Allocation Programs in Q3 2025, and continue to participate in:
WebX Tokyo (August)
Bitcoin 2025 HK (August)
Multiple overseas private exchange dinners (Shenzhen, Hangzhou, Chengdu, etc.)
We want to be there for those who really need security, rather than just appearing on the crest of the market wave.
