Stablecoins from Ethereum to Solana: USDT ERC20 → USDC SOL

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

As of Sep 17, 2026 15:48 it is 1 USDT ERC20 = 1.0013 USDC 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 USDT ERC20 → USDC SOL accept?

From 100 to 10,000,000 USDT ERC20 per order. The lower limit is roughly $99.91.

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

Network fees and order handling eat a small transfer alive — below 100 USDT 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 USDT ERC20, and that one goes to the blockchain, not to us.

Q: How long does USDT ERC20 to USDC 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 USDC arrive, or a wrapper?

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

Q: Do I need SOL to receive USDC SOL?

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

Q: Which network will USDC SOL arrive in?

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

Q: Where is receiving USDC cheaper?

The cheapest is usually USDC Polygon, USDC SOL, USDC Arbitrum, USDC BEP20, USDC AVAX C, USDC 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.

USDC network fees

How the USDT ERC20 → USDC SOL order runs

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

Swap USDT ERC20 for USDC SOL

Check this before sending USDT ERC20

The address network is Solana. Sending through another network usually means losing the transfer.
The transfer must not be smaller than 100 USDT ERC20.
Copy the address whole, then compare the first and last characters after pasting.
To move USDC 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.
