Roobee wallet

What is Roobee (ROOBEE)?

Roobee started as a platform aimed at people putting small amounts into investment products, with the ROOBEE token as the access and utility unit around that service. The part that matters once the token is in your hands has less to do with the platform and more with where it sits: ROOBEE is not a single-chain token. It was deployed on Ethereum first and then spread across several EVM chains, each with its own contract and its own separate balance.

That has a few consequences you feel immediately. Your address looks identical on all of them, but the tokens do not travel between chains by themselves - ROOBEE on one chain reaching a destination expecting another chain's version simply will not show up there, and getting it across means a bridge. The fee coin changes too: the same transfer costs ETH on Ethereum, BNB on BNB Smart Chain, AVAX on Avalanche, POL on Polygon, and ETH again on the two rollups, where the amounts are far smaller. Whichever chain you actually use, that chain's native coin has to be sitting in the wallet before you can move a single ROOBEE.

Supported networks in Tangem (6): Arbitrum One, Ethereum, Optimism, BNB Smart Chain, Avalanche, Polygon POS. Tangem holds those fee coins in the same wallet as the token, so covering a Polygon or Arbitrum transfer does not mean going to fetch gas from somewhere else, and signing is a tap of the card against the phone - no cable, no charging, nothing to plug in on a chain you only use occasionally. For a token scattered across this many chains, that is the convenience worth having.
