Vietnamese team SEI Lab discusses Family Haven, a non-custodial wallet for families built on Soroban. The product addresses $7 billion in elderly asset losses through guardian protection and recovery features, deployed on testnet. Team won third prize at the APAC Hackathon.
SEI Lab brought Family Haven to the APAC Hackathon to solve the $7 billion problem of elderly people losing access to crypto assets due to lost keys and manipulation. The four-person team—product lead Kai, technical lead Guang Huy, UX designer Hoang Anh, and finance engineer Huy Minh—built a non-custodial family wallet on Soroban combining three layers: everyday payments, guardian-based protection against fraud, and social recovery for inheritance and asset continuity. The product shipped live on testnet with five verified smart contracts during the hackathon itself, a working implementation that distinguished it from typical paper proposals and impressed judges. They won third prize in the consumer and application track. Looking ahead, the team plans to implement on-chain guardian consent mechanisms to complete the full inheritance and long-term financial planning model for families.
