Mixin wallet

What is Mixin (XIN)?

XIN is the native asset of Mixin Network, a transactional layer designed to move assets from other chains quickly and cheaply, with node operators bonding XIN to run the network. The supply is capped at one million units, which is why the unit price looks nothing like a typical token and why most holdings are fractional, and sending a fraction of a XIN is completely normal.

The practical wrinkle is that XIN has lived in more than one place. It began as an ERC-20 on Ethereum, and that Ethereum balance is what most self-custody wallets hold, while XIN inside Mixin's own network is a separate representation of the same asset. Moving between them is a deposit or withdrawal through Mixin, not a wallet-to-wallet send, and the Ethereum and Solana balances are likewise distinct: an address on one chain will not see tokens sent on the other.

Fees follow whichever chain you are on. On Ethereum that is ETH. On Solana it is SOL, plus a small one-off rent deposit for the token account that has to exist before your address can receive the token at all.

Tangem keeps each chain's balance on its own line and names the network on the confirmation screen before the card signs, so you are choosing the route deliberately rather than by habit, and the SOL or ETH for the fee sits right beside the XIN. Networks supported in Tangem (2): Ethereum, Solana. Given an asset that appears in several forms under one ticker, having the chain spelled out at signing time is the difference that counts.
