Tether USD

Overview

USDT dominates offshore trading volume and emerging-market remittance flows, but no card network accepts it for settlement. The contrast is instructive: settlement eligibility is driven by reserve quality and regulatory posture, not by market cap or liquidity.

If you handle inbound crypto payments you will still encounter USDT constantly — hence its inclusion in this reference — but treat it as a customer-side asset, not a network-settlement asset.

Card-network settlement support

The largest stablecoin by float, but absent from every card-network settlement program — the networks’ selection criteria (full reserves, US/EU regulatory alignment) exclude it. Included here for completeness.

Regulation & reserves

Mixed reserves (US Treasuries plus other assets incl. secured loans and bitcoin); quarterly attestations, no full audit.

Chain deployments

Always verify contract addresses against the issuer’s official documentation before use — lookalike tokens with identical symbols are a common scam vector.
