Three steps on Web3Swap
-
Enter the MATIC size and paste the Ethereum (Base) payout address for Base mainnet on this Web3Swap ticket.
-
Confirm Exchange to lock the live Web3Swap quote and reveal this ticket’s deposit details.
-
Broadcast exactly that MATIC amount to the deposit. After Polygon mainnet confirms, ETH is paid to your wallet.
Before you broadcast
- Polygon confirmations are usually fast — often within a minute.
- Send MATIC on Polygon PoS mainnet only — not Ethereum or other L2s unless your order says otherwise.
- Use a Polygon-compatible wallet and address (0x…). Leave enough MATIC for gas.
- If ETH 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.
Polygon tickets — PoS rail, not Ethereum L1
MATIC/POL powers Polygon’s low-fee EVM environment. Web3Swap Polygon tickets reject Ethereum-mainnet assets — match the PoS badge before you broadcast.
MATIC on Polygon mainnet
Use a Polygon PoS wallet for deposits. Do not send MATIC on Ethereum mainnet — wrapped versions are different assets.
Leave enough MATIC in your wallet to cover gas on top of the swap amount.
Base ETH tickets — Coinbase L2 rail
Native ETH on Base is not Ethereum L1. Web3Swap Base tickets need a Base wallet — low fees, fast finality, still no hosted balance.
Base ETH not received?
Confirm your wallet is on Base mainnet and fully synced — not Ethereum L1.
Base ETH payout tips
- Payouts go to Base — verify your wallet network is Base (chain ID 8453).
- Check Basescan with the payout tx hash from your order page.
- Bridging to Ethereum L1 is a separate step after you receive ETH on Base.
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 MATIC → ETH?
No. A standard Polygon → Ethereum (Base) ticket on Web3Swap skips signup and ID upload. You stay self-custodial on both legs.
How soon does ETH usually arrive?
After the Polygon mainnet deposit is final, many payouts leave within minutes. Congestion on Polygon mainnet or Base mainnet can stretch that — mempools and fees set the clock, not a compliance hold.
Does Web3Swap custody my MATIC or ETH?
No. You broadcast MATIC from a wallet you control; ETH pays only to the address you paste. Nothing sits as a named Web3Swap balance.
What if I send MATIC on the wrong rail?
Match Polygon mainnet exactly as printed on the Web3Swap ticket badge. A wrong-chain deposit often cannot be credited automatically — verify before you broadcast.
