Wallet

Human.tech has announced an AI-agent wallet infrastructure called Agentic Wallet as a Protocol (WaaP) that converts wallet actions into natural-language interactions while keeping users as the final authority. The system uses cryptographic controls such as spending limits, time windows, approved addresses and step-up human approvals for higher-risk actions. The company says its Human Passport ecosystem has more than 3 million users, has secured over $500 million against Sybil attacks, and is backed by $3 billion in restaked ether.

An Oobit study of 1,000 U.S. crypto holders found that 35% have lost access to a wallet or account, most often due to human error rather than hacking.

Among those locked out, more than 1 in 10 said a single incident cost them over $5,000, and the median reported loss was 30% of total crypto holdings.
