What separates an EMT from an ART
An E-Money Token, or EMT, is a stablecoin referencing a single official currency, such as the euro, and is legally treated as electronic money under MiCA: holders have a direct claim to redeem it at par value at any time. An Asset-Referenced Token, or ART, references a basket of currencies, commodities or other assets, or a single non-official currency, and carries a different, more complex reserve and redemption regime.
Most stablecoins used for day-to-day EU payments are structured as EMTs precisely because MiCA gives EMT holders the strongest, clearest redemption right of the two categories.
Why the issuer rules differ
EMT issuers must be authorized as a credit institution or an electronic money institution, hold reserves at least equal to the tokens in circulation, and keep those reserves segregated from the issuer's own funds. ART issuers face additional requirements: a more detailed reserve composition policy, liquidity management rules, and lower thresholds before "significant" ART status triggers extra supervision from the European Banking Authority.
An ART issuer also cannot pay interest to token holders under MiCA, closing off a structure some earlier stablecoin models used to attract holders.
Why the distinction matters for a payment or settlement partner
A bank or merchant settling payments in a MiCA stablecoin should know which category it is buying into before relying on it operationally: an EMT gives a clear, at-par redemption claim suited to payment settlement; an ART's redemption terms depend on the specific reserve policy disclosed in its white paper, and can differ meaningfully between issuers.
For infrastructure built to settle B2B payments in stablecoin, defaulting to EMT-classified tokens for anything used as a cash equivalent is the more conservative, and generally more appropriate, choice.
