Stablecoins from Ethereum to Solana: USDC ERC20 → USDT SOL

Q: What rate does USDC ERC20 to USDT SOL run at?

As of Sep 18, 2026 06:28 it is 1 USDC ERC20 = 1.002 USDT SOL. The figure recalculates on its own, and the calculator always shows the fresh one. In dollars that is around $1.00.

Q: What amounts does USDC ERC20 → USDT SOL accept?

From 100 to 10,000,000 USDC ERC20 per order. The lower limit is roughly $99.96.

Q: Where does the 100 USDC ERC20 floor come from?

Network fees and order handling eat a small transfer alive — below 100 USDC ERC20 the swap stops making sense for either side.

Q: What else is taken on top of the rate?

The payout is already calculated at the rate in the calculator. On top of it you only pay the network fee for sending USDC ERC20, and that one goes to the blockchain, not to us.

Q: How long does USDC ERC20 to USDT SOL take?

The clock starts with confirmations: the order goes into work once Ethereum (ERC20) confirms your transfer. After that it comes down to how busy the network is. A block in Ethereum (ERC20) closes in about 12 sec.

Q: Will native USDT arrive, or a wrapper?

USDT SOL is the standard USDT token in Solana — exactly what exchanges send when they withdraw into this network.

Q: Do I need SOL to receive USDT SOL?

Not to receive. SOL comes into play later, when you want to send USDT from your address.

Q: Which network will USDT SOL arrive in?

The payout leaves in Solana. Make sure the receiving wallet works with that network.

Q: Where is receiving USDT cheaper?

The cheapest is usually USDT SOL, USDT Polygon, USDT Arbitrum, USDT TON, USDT BEP20, USDT AVAX C, USDT Optimism. Still, the network is chosen by what the recipient supports, not by the fee.

Q: What if the rate moves while I am paying?

The rate is pinned to the order and does not move while the order is alive. It can be recalculated if the payment arrives late or for a different amount — so send the exact sum, and send it promptly.

How the USDC ERC20 → USDT SOL order runs

Work out the amount in the calculator: orders start at 100 USDC ERC20.
Enter a USDT address in Solana and a way to reach you.
Send USDC ERC20 in Ethereum (ERC20) for exactly the amount stated in the order.
Once the network confirms your transfer, Tether leaves for your address. The order page tracks every step.

Swap USDC ERC20 for USDT SOL

Check this before sending USDC ERC20

The address network is Solana. Sending through another network usually means losing the transfer.
The transfer must not be smaller than 100 USDC ERC20.
Copy the address whole, then compare the first and last characters after pasting.
To move USDT on later, put a little SOL at the same address.
Coins go through an AML check: a flagged transfer can be held until the check is finished.
