Tunnel in 3 steps

  1. Choose how much BTC to send and paste the Cronos address that should receive funds on ERC-20 on Ethereum.

  2. Open the order to freeze the quote and reveal a one-time deposit destination.

  3. Broadcast BTC to that destination. Once confirmations clear, CRO is pushed to your payout wallet.

Before you broadcast

  • 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.
  • Still waiting on CRO? Give the wallet a few minutes to sync, then share your Exchange ID with support if the order already lists a payout hash.

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.
