MAI (Optimism) wallet

What is MAI (Optimism) (MIMATIC)?

Think of MAI as a dollar someone borrowed into existence. QiDao lets a user lock collateral in a vault and mint MAI against it; the vault is closed by returning the MAI. Because minting always requires more collateral than the MAI created, the supply stays backed, and because it lives entirely in contracts, there is no company issuing or reclaiming it. The ticker MIMATIC is a remnant of the network where the project started and does not connect MAI to that network's coin.

For day-to-day holding, the things that actually come up are these. MAI is a separate ERC-20 on each network it was deployed to, so the balance you see belongs to this chain alone and reaching another one requires a bridge. Transaction fees come out of the chain's native coin, not out of MAI. And the peg is a target, not a promise, so expect small deviations rather than a fixed number.

Supported networks in Tangem (1): Optimism.

Stablecoins tend to get used, not stored - paying someone, topping up, settling a swap - and Tangem suits that rhythm because a transfer is approved by holding the card against the phone, with the gas coin sitting in the same wallet as the MAI it will pay for. No cable, no charge level to worry about, nothing to unlock beyond the tap. If your MAI is working money rather than a reserve, that is reason enough to keep it in the card.
