Three steps on Web3Swap
-
Enter the ETH size and paste the Avalanche payout address for Avalanche C-Chain on this Web3Swap ticket.
-
Confirm Exchange to lock the live Web3Swap quote and reveal this ticket’s deposit details.
-
Broadcast exactly that ETH amount to the deposit. After Base mainnet confirms, AVAX is paid to your wallet.
Before you broadcast
- Base confirmations are usually fast — often within a minute.
- Send ETH on Base mainnet only — not Ethereum L1, Optimism, or Arbitrum unless your order says otherwise.
- Use a Base-compatible wallet and address (0x…). Leave enough ETH on Base for gas on top of the swap amount.
- If AVAX 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.
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.
ETH on Base mainnet
Use a Base wallet for deposits. Ethereum mainnet ETH is a different network — wrong-chain sends may not be credited.
Leave enough ETH on Base for gas in addition to the amount you swap.
Avalanche C-Chain tickets on Web3Swap
AVAX on the C-Chain is an EVM rail with quick finality. Other AVAX deployments are separate — trust the C-Chain badge on the Web3Swap ticket.
AVAX not received?
Confirm your wallet is set to Avalanche C-Chain and fully synced.
AVAX payout tips
- Payouts go to Avalanche C-Chain — use a 0x-style address compatible with your wallet.
- Check Snowtrace or a similar explorer with the payout tx hash from your order page.
- Allow a minute for your wallet to refresh after the explorer shows the transfer.
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 ETH → AVAX?
No. A standard Ethereum (Base) → Avalanche ticket on Web3Swap skips signup and ID upload. You stay self-custodial on both legs.
How soon does AVAX usually arrive?
After the Base mainnet deposit is final, many payouts leave within minutes. Congestion on Base mainnet or Avalanche C-Chain can stretch that — mempools and fees set the clock, not a compliance hold.
Does Web3Swap custody my ETH or AVAX?
No. You broadcast ETH from a wallet you control; AVAX pays only to the address you paste. Nothing sits as a named Web3Swap balance.
What if I send ETH on the wrong rail?
Match Base mainnet exactly as printed on the Web3Swap ticket badge. A wrong-chain deposit often cannot be credited automatically — verify before you broadcast.
