What is Streamr (DATA)?

Streamr is a peer-to-peer network for real-time data - sensor feeds, telemetry, live tickers - carried between applications without a broker sitting in the middle. DATA is the token that pays for that transport and bonds the nodes relaying it.

Two practical things about the token itself. It was reissued: the original Ethereum contract was superseded by a second-generation one, with holders migrating across at a one-to-one ratio, so a balance that has been sitting in cold storage since the early years may still be the retired version. Confirm which contract you hold before you make plans for it. And DATA is deployed on several chains at once, with day-to-day Streamr activity having drifted towards cheaper networks than Ethereum mainnet. Each deployment is a separate balance with its own gas coin, so whichever chain your DATA sits on dictates what else you need at that address.

Supported networks in Tangem (4): Ethereum, BNB Smart Chain, Polygon POS, Gnosis Chain.

Each of those deployments gets its own line in the app, and the network name forms part of the confirmation you read before touching the card to the phone - the check remains yours to make, but nothing is hidden from you while you make it. Split as it is across chains and across a contract generation, DATA calls for a wallet that spells out both, and a Tangem card does.
