Preliminary figure: the final amount is locked in the order.

Right now 1 STRK ERC20 gets you 0.0421312 USDC Polygon; the other way round, 1 USDC Polygon is 23.7354 STRK ERC20. Over 24 hours STRK ERC20/USDC Polygon came in at minus 2.77%. Over the week, minus 1.44%.

The weekly range ran from 0.0382363 to 0.043743 USDC Polygon, a spread of 14.4%. One order takes from 2,373.17 to 236,000,000 STRK ERC20. In dollars that is roughly $100.43.

The robot sends the payout in the Polygon network, so the address has to belong to that network — a transfer to another one will not arrive. Market capitalisation puts Starknet at No. 150 ($311.05 M) and USD Coin at No. 6 ($74.34 B). Over 90 days the daily moves of STRK and USDC correlate at -0.01 (they travel apart).

Which network USDC arrives in

The same USDC goes out in several networks. Each has its own rate and its own floor, and the fee is charged by the network itself.

Common questions: STRK ERC20 → USDC Polygon

What rate does STRK ERC20 to USDC Polygon run at?

As of Sep 30, 2026 16:05 it is 1 STRK ERC20 = 0.0421312 USDC Polygon. The figure updates on its own, and the calculator always shows the current one. On the market that is around $0.0421242.

What amounts does STRK ERC20 → USDC Polygon accept?

From 2,373.17 to 236,000,000 STRK ERC20 per order. The floor is roughly $100.43.

Why can I not swap less than 2,373.17 STRK ERC20?

The network fee and the handling do not depend on the amount. On a transfer below 2,373.17 STRK ERC20 they eat a noticeable share of it, and the swap stops making sense for either side.

Is anything charged on top of the rate?

No. The payout is already worked out at the rate in the calculator. Separately you pay only the network fee for sending STRK ERC20, and the blockchain takes that one.

How long does swapping STRK ERC20 for USDC Polygon take?

Which network will USDC Polygon arrive in?

The payout goes out on Polygon. Check that the receiving wallet supports that network.

Which network is cheaper for receiving USDC?

Usually USDC SOL, USDC Arbitrum, USDC BEP20, USDC AVAX C, USDC Optimism, USDC Polygon 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.
