Dai wallet

What is Dai (DAI)?

Dai is the stablecoin issued by the Maker protocol, which now operates under the Sky name. It is created when someone locks crypto and other collateral in a vault and mints DAI against it, and it is burned when that debt is repaid. The peg to one US dollar is held by overcollateralization and by the protocol's own rate mechanisms, not by a company that redeems tokens for cash. The result is a token that behaves like a dollar in your wallet but has no custodian behind it.

A few things a holder should know before choosing where to keep it:

• On Ethereum, DAI is an ordinary ERC-20 token. Sending it costs gas in ETH, so a DAI-only wallet cannot move its DAI until it holds a little ETH as well. The same logic applies on any other network where DAI exists: the network's own coin pays the fee, not the DAI.
• The current token is Multi-Collateral DAI. The original Single-Collateral version was renamed SAI and is long retired; if you ever see "SAI", it is the old one, not this asset.
• Since the Sky rebrand there is a newer stablecoin, USDS, convertible with DAI one to one. DAI has not been shut down and still circulates on its own; the two are separate tokens with separate balances.
• sDAI is a different token again: a vault share that represents DAI deposited with the protocol. A plain DAI balance does not change on its own, whichever wallet holds it.
• Outside Ethereum, DAI on other chains is a bridged representation, and the same address can hold DAI on more than one of them at once.

That last point is what matters most for a wallet. Tangem keeps DAI as a separate balance for each network and shows, before the card signs, on which network the transfer is going out, so you can compare that with what the recipient asked for. For an asset that exists in several bridged copies, that one line on the confirmation screen is the reason to hold it here.
