What is USDT
USDT is a fiat-pegged stablecoin issued by Tether Limited. Each token is intended to represent one US dollar of reserves held by the issuer, with reserves disclosed quarterly in attestation reports. USDT is the oldest and largest stablecoin by market capitalisation, with multi-chain issuance across Ethereum (ERC-20), Tron (TRC-20), Solana (SPL), Avalanche, and others.
In iGaming, USDT is typically the first stablecoin an operator integrates. Customer demand is highest for USDT, particularly on Tron where transaction fees are a fraction of those on Ethereum. Many operators that accept a single stablecoin accept USDT only; those that accept two normally pair USDT with USDC.
How USDT moves through operator rails
Operators provision per-customer deposit addresses on each supported USDT chain. Deposits credit the customer balance after the required confirmations (typically one block on Tron, twelve blocks on Ethereum). Withdrawals are signed from a hot wallet against the customer’s nominated chain and address. Treasury teams reconcile hot-wallet balances against the off-chain customer ledger continuously and replenish from cold storage as needed.
Tron-USDT is the dominant chain for high-frequency, low-value deposits because gas fees are typically under one cent. Ethereum-USDT is preferred for large balances by customers who already hold ETH for gas. Solana-USDT is growing for low-latency, high-throughput use cases.
Why USDT matters in B2B
For platform vendors, USDT integration across three chains (ERC-20, TRC-20, SPL) is the practical floor for any crypto-native operator. For PSPs, USDT corridors deliver the highest transaction volume in the crypto book. For compliance teams, Tether’s history of disclosure scrutiny, occasional reserve concerns, and exposure to sanctioned addresses (which Tether has frozen on request from law enforcement) means USDT receives heightened screening attention. Operators in regulated markets often restrict USDT acceptance more tightly than USDC for that reason.
Frequently asked questions about What Is USDT (Tether) in iGaming?
Operationally, USDT is the most liquid stablecoin and has held its dollar peg over multiple market cycles. From a compliance perspective, Tether discloses reserves quarterly and freezes addresses on request from law enforcement. Some regulated operators restrict USDT acceptance to convert-at-deposit flows for those reasons.
Tron-USDT (TRC-20) by transaction count and customer preference for low-value deposits, plus Ethereum-USDT (ERC-20) for customers with existing ETH balances. Solana-USDT is a strong third for low-latency throughput.
Both are US dollar-pegged stablecoins. USDT is issued by Tether Limited and has higher market cap and trading volume. USDC is issued by Circle and is generally regarded as more conservative on disclosure and reserves. Both are widely accepted in iGaming.
Yes. Tether has frozen wallet addresses on request from US and other law enforcement agencies. KYT screening through Chainalysis or Elliptic flags exposure to sanctioned or high-risk USDT addresses before accepting a deposit.
