Smog wallet

What is Smog (SMOG)?

Smog is a dragon-themed meme token that began on Solana and later appeared on Ethereum as well. The two are separate deployments: an SPL token on one chain, an ERC-20 on the other, each with its own contract and its own balance. They are not two views of one holding, and a Solana balance does not become an Ethereum balance by any action taken inside a wallet.

That split changes the small print depending on where you hold it. On Solana, the token lives in an associated token account tied to your wallet address, and that account has to exist before anything can be received; creating it costs a small amount of SOL as rent, and SOL also pays the transaction fee, which is fractions of a cent but has to be there. On Ethereum, the same job is done by ETH at ordinary gas prices, which for a meme position often costs more than the transfer is worth thinking about.

Either way the pattern is the same: you cannot move the token without holding a little of the chain's own coin beside it.

Tangem keeps SOL or ETH in the same wallet as the Smog balance it pays for, and a transfer is approved by tapping the card against the phone, so there is no battery to watch and nothing to plug in before a quick send. For a token people move in small amounts and on impulse, that removes the step most likely to get in the way.
