Three steps on Web3Swap
-
Enter the USDC size and paste the Monero payout address for Monero mainnet on this Web3Swap ticket.
-
Confirm Exchange to lock the live Web3Swap quote and reveal this ticket’s deposit details.
-
Broadcast exactly that USDC amount to the deposit. After ERC-20 on Ethereum confirms, XMR is paid to your wallet.
Before you broadcast
- ERC-20 USDC follows Ethereum confirmation times.
- Send USDC on Ethereum mainnet only for this route — not Polygon, Base, or Solana USDC.
- Leave ETH in your wallet for gas when sending USDC.
- If XMR 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.
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 on Ethereum mainnet
Use an ERC-20 compatible Ethereum address. L2 USDC is a different asset on-chain.
Gas fees apply to token transfers — ensure sufficient ETH balance.
Monero tickets — subaddress hygiene
Monero Web3Swap tickets expect a fresh subaddress each time. After payout, wait for wallet scan to finish — the GUI can lag even when the ticket already shows complete.
XMR payout not showing?
Wait for wallet sync to complete — Monero often needs several minutes to reflect incoming outputs.
If the order lists a payout tx but your synced wallet shows nothing, contact support.
Receiving XMR with privacy intact
Monero payouts use one-time addresses — your wallet must finish scanning recent blocks to display the balance.
- Use a fresh subaddress for each swap rather than reusing old receive addresses.
- Compare your wallet block height with a public explorer before assuming a payout failed.
- Allow extra time after the order shows sent — privacy features can delay wallet display.
Deposit checklist
Chain mismatches and bad addresses are the usual failure modes — skim these notes before you fund the deposit.

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