How the ZRX → USDT SOL exchange runs
- Work out the amount in the calculator — orders start at 837.5208 ZRX.
- Give a USDT address on Solana and a contact for the order.
- Send ZRX on 0x Protocol, exactly the amount the order shows.
- Nothing else is needed from you: as soon as the network confirms the transfer, the robot sends Tether to your address. The order page shows the status.
Check this before sending ZRX
- The address network is Solana. Sending through another network almost always means losing the transfer.
- The transfer must not be smaller than 837.5208 ZRX.
- Copy the address in full, then check its first and last characters once it is pasted.
- Send exactly the amount stated in the order: the automation matches your payment against it, and any difference sends the order back for recalculation.

What rate does ZRX to USDT SOL run at?
As of Sep 30, 2026 21:45 it is 1 ZRX = 0.124199 USDT SOL. The figure updates on its own, and the calculator always shows the current one. On the market that is around $0.12414.
What amounts does ZRX → USDT SOL accept?
From 837.5208 to 80,700,000 ZRX per order. The floor is roughly $103.79.

No. The payout is already worked out at the rate in the calculator. Separately you pay only the network fee for sending ZRX, and the blockchain takes that one.

Which network will USDT SOL arrive in?
The payout goes out on Solana. Check that the receiving wallet supports that network.
Which network is cheaper for receiving USDT?
Usually USDT BEP20, USDT SOL, USDT Arbitrum, USDT AVAX C, USDT Optimism works out cheaper. Still, the network is picked by what the recipient accepts, not by the fee.
What happens if the rate moves while I am paying?
Nothing: the rate is locked in the order and holds for as long as the order is alive. It is recalculated only if the payment arrives late or for a different amount — so send the exact sum, and send it promptly.
