1. Tether USD (USDT)
Issued by Tether Limited · British Virgin Islands
The largest stablecoin by far. Dominant in trading pairs and emerging-market remittances. Weaker regulatory transparency than USDC—no major-jurisdiction license, quarterly rather than monthly attestations—but unmatched liquidity across chains.
