Swap Cosmos → Ethereum (Base) (no KYC)

Looking for ETH on Base mainnet? Keep custody of both ends: quote on ToSwap, push Cosmos from your wallet, collect Ethereum (Base) automatically once the deposit depth clears. Private by design — no account to open.

    Three steps on ToSwap

    1. Set the ATOM amount and paste the Ethereum (Base) address that should collect payout on Base mainnet.

    2. Tap Exchange to lock the live ToSwap quote and reveal this order’s deposit details.

    3. Send exactly that ATOM amount to the deposit. After Cosmos mainnet confirms, ETH is pushed to your wallet.

    Before you broadcast

    • Payout starts after Cosmos mainnet has enough confirmations.
    • If a deposit sits unconfirmed, check chain status — congestion can slow inclusion.
    • Broadcast only ATOM on Cosmos mainnet to the deposit shown on your order.
    • If ETH is late, refresh your wallet and re-check the order status. When a payout hash is already listed, email or SimpleX support with your Exchange ID — ToSwap has no login that can reopen expired pages.
    You send

    Cosmos

    Credit ATOM only on Cosmos mainnet. A transfer on any other chain will not show up on this order.

    Deposit checklist

    Open a wallet that can send on Cosmos mainnet.

    The wallet network must match the deposit network printed on the order.

    You receive

    ETH on Base — Coinbase L2

    Native ETH on Base — Ethereum's value on Coinbase's L2 with low fees, fast finality, and growing on-chain activity.

    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.

    Deposit amount must match exactly Under- and over-payments can delay or fail automated crediting. What each swap status means From awaiting deposit to complete — read each status on your order page. How to track swap order status Use your exchange ID and read each status on the order page. What happens when a swap order expires? Deposit windows close — sending late may require a fresh order.

    FAQ for this route

    Is KYC or a ToSwap account required for ATOM → ETH?

    No. ToSwap never opens a profile or asks for ID documents on a standard Cosmos to Ethereum (Base) order. You stay non-custodial on both legs.

    How fast does ETH usually arrive?

    Many payouts leave within minutes after the Cosmos mainnet deposit confirms. Congestion on Cosmos mainnet or Base mainnet can stretch that — fees and mempools set the clock, not a manual review.

    Does ToSwap hold my ATOM or ETH?

    No hosted balance. You broadcast ATOM from a wallet you control; ETH is paid only to the address you paste. Nothing sits under a ToSwap username.

    What if I send ATOM on the wrong network?

    Match Cosmos mainnet exactly as printed on the order badge. A wrong-chain deposit often cannot be credited automatically — double-check before you broadcast.
