Гаманець для SwapBased COIN

What is SwapBased COIN (COIN)?

SwapBased is an automated market maker native to Base, with concentrated liquidity pools and a perpetuals venue built on top of it. COIN is the token inside that system, wired into the protocol's reward mechanics and into its BASE token rather than being a standalone asset with a life outside the exchange.

The thing to get right before you move it is identification. "COIN" is one of the most overloaded tickers in existence: it is the stock symbol of a large listed exchange company, and several unrelated tokens use it too. None of that is related to this one. The token you hold here is defined by being a Base contract, and that is the only thing that distinguishes it - a ticker match on a listing page proves nothing.

Base is an Ethereum rollup, so COIN behaves like any ERC-20 there: transfers are inexpensive but settle in ETH bridged to Base. ETH sitting on Ethereum mainnet will not pay a Base fee, which catches people who bridge the token across and forget to bring gas with it.

Supported networks in Tangem (1): Base.

A Tangem card handles this with a tap against the phone - the key stays in the chip, the signature comes back, and the Base ETH that covers the fee lives in the same wallet as the COIN. Holding a DEX token and its gas coin together in one place is simply less to think about.
