Mainnet → Optimism

Swap DOT to USDC

Exchange DOT from Polkadot into USDC on OP Mainnet. The provider waits for the DOT deposit before arranging the USDC payout on the destination network. Track those as separate transactions rather than using a sending-chain confirmation as proof of receipt.

Polkadot (Mainnet) to USDC (Optimism)

You send: Polkadot (Mainnet)DOT · Mainnet
You receive: USDC (Optimism)USDC · Optimism

Enter your amount to check live availability for DOT on Mainnet → USDC on Optimism. A provider quote is required before you can create a swap.

Address and network checks

Use the order’s Polkadot deposit address for DOT, and your own OP Mainnet receiving address for USDC. Keep the refund address on Polkadot; the payout address is not automatically a valid refund destination.

Sending DOT

Choose Polkadot using the Mainnet option shown in this directory. Follow the selected provider’s exact deposit instructions before sending. The provider labels this entry Mainnet. Check the exact DOT deposit network shown in the final order and in your wallet; do not infer support for every parachain or transfer route from the DOT ticker.

For a standard self-custody transfer on Polkadot, allow for network fees in DOT in addition to the amount you send. Wallet sponsorship and exchange withdrawal charges can differ; check the sending wallet’s final fee.

Receiving USDC

Select OP Mainnet, often labeled Optimism. Its ETH balance and token balances are separate from those on Ethereum mainnet. Confirm the destination supports the exact USDC version returned by the provider. In particular, do not assume USDC, USDC.e and Binance-Peg representations are interchangeable. This listed USDC/Optimism option has no separate memo field. If your destination requires additional instructions that this form cannot supply, choose another compatible destination before creating an order.

RECEIVING ASSET

USDC on OP Mainnet

USDC is Circle’s dollar-referenced stablecoin. Native USDC and bridged representations can coexist, so a familiar ticker alone is not enough to identify a deposit asset.

Does a confirmed DOT deposit mean my USDC has arrived?
