Universal Basic Income wallet

What is Universal Basic Income (UBI)?

UBI is an experiment in distributing a token by identity rather than by purchase. It was the first application built on Proof of Humanity, the Kleros-backed registry where each entry is one verified human vouched for by others and challengeable on-chain. An address accepted into that registry can start accrual, and from then on the contract streams UBI to it continuously - the balance is computed from elapsed time, not from any action you take.

That design splits holders into two kinds, and it matters for a wallet decision. If your address is the registered human one, it is doing something no other address can do, and losing the key does not just lose tokens, it severs the accrual from a registry entry that took vouching and a deposit to establish. If you simply bought UBI on the open market, you hold an ordinary ERC-20 on Ethereum with nothing tied to your identity, and fees are paid in ETH like any other token there. The symbol is also generic enough that unrelated tokens have used it, so go by the contract.

Supported networks in Tangem (1): Ethereum.

For the address that is the registry entry, key custody is the whole question. Tangem generates the key inside the card's chip, where it stays, and the backup is a second identical card you keep somewhere else rather than a phrase on paper - though a seed phrase remains available if you would rather have one. An identity-bound address is something you want to still control years later, and a pair of cards is a plain way to make sure of that.
