What rate does ETHFI to USDC Polygon run at?

As of Oct 1, 2026 04:30 it is 1 ETHFI = 0.774627 USDC Polygon. The figure updates on its own, and the calculator always shows the current one. On the market that is around $0.774445.

What amounts does ETHFI → USDC Polygon accept?

From 128.5204 to 12,900,000 ETHFI per order. The floor is roughly $99.77.

Why can I not swap less than 128.5204 ETHFI?

The network fee and the handling do not depend on the amount. On a transfer below 128.5204 ETHFI they eat a noticeable share of it, and the swap stops making sense for either side.

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

How long does swapping ETHFI for USDC Polygon take?

The clock starts with confirmations: as soon as Ether.fi confirms your transfer, the order goes out for payout with no operator involved. After that the timing is set by how busy the network is — which is the difference between quick and instant.

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.
