    Exchange in 3 steps

    1. Choose how much BTC to send and enter your Ethereum address on Native on Optimism.

    2. Hit Exchange to open your order page with the live rate and deposit details.

    3. Transfer BTC to the address on your order — after confirmations, ETH is sent to your wallet automatically.

    What do you need to know?

    • One on-chain confirmation is usually enough before your payout leg starts.
    • BTC confirmation time depends on mempool congestion and the fee you paid.
    • SegWit deposit addresses keep fees lower. If your wallet cannot send to SegWit, contact support before sending.
    • ETH not visible yet? Wait a few minutes, resync your wallet, then contact support with your order ID if the payout tx is already listed.

    Bitcoin — the original digital asset

    Since 2009, Bitcoin has been the benchmark cryptocurrency — deep liquidity, wide recognition, and the default on-ramp for cross-chain swaps.

    Before you send BTC

    • Confirm your wallet can send to SegWit (bc1…) addresses.
    • Leave enough for a network fee — low fees mean slower confirmation.
    • Send only BTC on Bitcoin mainnet to the address on your order page.

    How long until Bitcoin confirms?

    Block times vary with network load and your chosen fee.

    • Use mempool.space or similar tools to check whether your fee is competitive.
    • Explorers show queue position — compare against pending transaction volume.
    • Average block interval is ~10 minutes, but longer gaps happen.

    Why traders move BTC to other chains

    Bitcoin offers deep liquidity and wide recognition — many swaps start with BTC as the funding asset.

    Moving into Ethereum, stablecoins, or alt L1s lets you access DeFi, payments, or portfolio diversification without a custodial account.
