Question 1

What are USDT and USDC?

Accepted Answer

USDT and USDC are stablecoins: blockchain tokens pegged 1:1 to the US dollar. Each token is backed by reserves of cash and short-term US Treasuries, which keeps the market price at roughly a dollar. In practice they behave like dollars that live on a blockchain. Transfers clear in minutes, and the network runs 24/7, with no bank hours or wire cut-offs to wait on.

Question 2

What's the difference between USDT and USDC?

Accepted Answer

Same dollar peg, different issuer. USDC is issued by Circle, a US-licensed company that publishes monthly reserve attestations. USDT is issued by Tether, the oldest and largest stablecoin by market cap, with the deepest liquidity across exchanges. For self-custody and transfers between wallets, the two are functionally the same.

Question 3

Is buying stablecoins legal?

Accepted Answer

Yes, in every country on the list. Trust Wallet's onramp partners hold local licenses to sell stablecoins for personal use. Purchases above the daily threshold per email (typically $700, sometimes lower) trigger an ID check and address verification. That's a standard AML requirement for any regulated crypto onramp.

Question 4

What verification is required?

Accepted Answer

Some verification is always required. Below the daily threshold ($700 per day per email, sometimes lower), email and phone verification is enough. Above it, providers ask for a passport photo and a selfie inside the app, which takes about five minutes — after that the daily limit usually rises to several thousand USD. This is a standard anti-money-laundering (AML) requirement for any regulated crypto onramp.

Question 5

Which networks can I use?

Accepted Answer

USDT works on Ethereum, BNB Smart Chain, Arbitrum, Polygon and Solana. USDC also works on Base. On Ethereum, BNB Smart Chain, Arbitrum and Base, Trust Wallet's FlexGas pays the fee from the stablecoin balance, so you don't need ETH or BNB. Polygon and Solana aren't on FlexGas, but their fees are a few cents at most, paid in POL or SOL. Pick the network your receiving exchange or wallet expects, and use the same one on both ends.

Question 6

What is FlexGas?

Accepted Answer

FlexGas is a Trust Wallet feature that lets you pay the network fee in the stablecoin itself instead of the chain's native token. A wallet holding only USDT or USDC can send those tokens out without first topping up a gas token. It runs on BNB Smart Chain, Ethereum, Arbitrum and Base.

Question 7

What if a country isn't on the list?

Accepted Answer

Other routes exist, but each comes with trade-offs the user has to weigh. For example, P2P is a popular option but carries the risk of receiving tainted crypto, which can lead to frozen funds or blocked bank accounts. Research your options and verify the source of funds.
