USDT for vendor payments — practical guide

Some vendors have started accepting USDT (Tether), a US dollar-pegged stablecoin, alongside or instead of volatile cryptocurrencies. Here is what USDT is, how it works in practice, and when it makes sense.

What makes USDT different

USDT is pegged to the US dollar — 1 USDT is always worth approximately $1.00. This eliminates the exchange rate calculation problem with Bitcoin or Monero, where the price can move between when you calculate the payment amount and when you complete the transaction. Paying $120 worth of USDT means sending exactly 120 USDT with no conversion calculation required.

Network choice matters

USDT exists on multiple blockchain networks including Ethereum (ERC-20), Tron (TRC-20), and Binance Smart Chain (BEP-20). The transaction fees vary dramatically by network. On Ethereum, a USDT transfer can cost $5 to $20 in gas fees. On Tron, the same transfer typically costs under $1. Ask your vendor which network their USDT address accepts before sending — sending ERC-20 USDT to a TRC-20 address results in permanent loss of funds.

Privacy considerations

USDT on most networks inherits the transparency of the underlying blockchain. Ethereum USDT transactions are publicly visible on etherscan.io. Tron USDT transactions are visible on tronscan.org. USDT is not a privacy coin. For orders where transaction privacy matters, Monero remains the better choice despite the additional setup complexity.

Getting USDT

USDT is available on most major exchanges. Buy USDT directly, choose the network your vendor specifies, and withdraw to a self-custodied wallet (the Atomic Wallet or Trust Wallet apps support multiple USDT networks) before sending to the vendor. Avoid sending directly from the exchange for the same privacy reasons that apply to other crypto payments.

USDT's stability advantage comes with a tradeoff: most USDT transactions run on the Ethereum or Tron networks, which are fully public ledgers. Anyone with the transaction hash can trace the payment. Converting USDT to Monero before sending, rather than sending USDT directly to the vendor, preserves the price stability of acquiring a stablecoin while restoring the privacy properties that make Monero the preferred final payment method.
