What is USDT?

Tether (USDT) is the world's largest stablecoin — a cryptocurrency designed to hold a value of ~$1, mirroring the US dollar. Each USDT is supposed to be backed by reserves (USD and equivalents), and it's used across exchanges as "digital dollars" for trading pairs and a stable store of value.

Market Snapshot

It runs on multiple blockchains — Ethereum, Tron, Solana, Avalanche, BNB Chain, and more — so there are USDT versions on each. Tron and Ethereum are the two most-used.

Risk factors (from the on-chain security check on its Ethereum contract):

• Mintable — supply can be inflated (expected for a fiat-backed stablecoin, but it means Tether controls issuance)
• Can blacklist addresses and pause transfers — a centralized authority can freeze funds
• Owner can change balances and tax structure is modifiable — again, consistent with a centralized issuer
• Not a honeypot, zero buy/sell tax, open source

This is inherent to how a centralized stablecoin works — the trade-off is stability and trust in the issuer vs. the decentralization of something like Bitcoin. Team/reserve transparency and governance are the standing question here, and the tokenomics/issuance is controlled by the issuer rather than a fixed schedule.

Where to buy — verified on all the major exchanges:
