Three steps on Web3Swap
-
Enter the ADA size and paste the USD Coin payout address for ERC-20 on Ethereum on this Web3Swap ticket.
-
Confirm Exchange to lock the live Web3Swap quote and reveal this ticket’s deposit details.
-
Broadcast exactly that ADA amount to the deposit. After Cardano mainnet confirms, USDC is paid to your wallet.
Before you broadcast
- Cardano deposits need several confirmations before the swap proceeds.
- Block times are around 20 seconds but can vary with network load.
- Use a Shelley-era Cardano address — legacy Byron formats may not be supported on all routes.
- If USDC is late, refresh your wallet and re-check the ticket. When a payout hash is already listed, email or SimpleX support with your Exchange ID — Web3Swap has no login that lists expired orders.
Cardano tickets — ADA address format
ADA is Cardano’s native proof-of-stake asset. On Web3Swap, paste a mainnet address your wallet owns and broadcast only ADA — wrong-network sends will not credit the ticket.
Sending ADA
Send native ADA on Cardano mainnet from a compatible wallet.
Leave enough ADA for the transaction fee in addition to your swap amount.
USDC tickets — ERC-20 unless the badge says otherwise
USD Coin on Ethereum mainnet is the default on this hub. A Solana or L2 USDC send will not credit an ERC-20 Web3Swap deposit — match the mint before you broadcast.
USDC not credited?
Verify your wallet is on Ethereum mainnet and the token contract matches official USDC on Ethereum.
When will USDC arrive?
ERC-20 USDC payouts follow Ethereum block times — usually minutes after your deposit confirms.
- Confirm your wallet is set to Ethereum mainnet, not Polygon, Base, or another L2.
- Add the official USDC token contract in your wallet if the balance does not appear automatically.
- Check the payout tx hash on Etherscan if your wallet shows no incoming transfer.
Why traders swap into USDC
USDC is widely used in DeFi and on exchanges that prefer a regulated dollar stablecoin.
On Ethereum mainnet it pairs naturally with ETH gas and most ERC-20 trading pairs.
Deposit checklist
Chain mismatches and bad addresses are the usual failure modes — skim these notes before you fund the deposit.

FAQ for this route
Do I need KYC or a Web3Swap login for ADA → USDC?
No. A standard Cardano → USD Coin ticket on Web3Swap skips signup and ID upload. You stay self-custodial on both legs.
How soon does USDC usually arrive?
After the Cardano mainnet deposit is final, many payouts leave within minutes. Congestion on Cardano mainnet or ERC-20 on Ethereum can stretch that — mempools and fees set the clock, not a compliance hold.
Does Web3Swap custody my ADA or USDC?
No. You broadcast ADA from a wallet you control; USDC pays only to the address you paste. Nothing sits as a named Web3Swap balance.
What if I send ADA on the wrong rail?
Match Cardano mainnet exactly as printed on the Web3Swap ticket badge. A wrong-chain deposit often cannot be credited automatically — verify before you broadcast.
