BrightID wallet

What is BrightID (BRIGHT)?

BRIGHT belongs to BrightID, a proof-of-uniqueness system: instead of documents, it builds a social graph in which people vouch for each other so an application can tell one human from a hundred accounts run by the same person. The token funds and steers BrightDAO, the community organisation around that identity network, and its distribution was deliberately built around the same principle, with allocations per person rather than per address.

Where it lives is dual. BRIGHT exists as an ERC-20 on Ethereum and also on Gnosis Chain, which is where most of the DAO's actual machinery runs, including proposal funding through conviction voting. Those are two separate balances of the same asset, linked by a bridge, and they do not add up inside one wallet view.

That split changes how fees feel. On Gnosis Chain transactions are paid in xDAI and cost fractions of a cent, so voting and small transfers are unremarkable. On Ethereum the same operation is paid in ETH at mainnet prices. Addresses look the same on both networks, which is convenient and also the reason network selection is the thing people get wrong.

Supported networks in Tangem (2): Ethereum, Gnosis Chain.

Inside Tangem each chain keeps its own balance and its own fee coin, and the network a transfer is leaving on is named on screen before you hold the card to the phone to approve it. For an asset that has a serious life on two chains at once, having that stated plainly at signing time is a good reason to keep it here.
