ETH → ADA

What makes ETH -> ADA specific

ETH and ADA live on fundamentally different architectures. Ethereum settles in roughly 12 second slots with variable gas priced in gwei; Cardano produces blocks every 20 seconds on average with deterministic, low fees (typically under 0.2 ADA per transaction). That asymmetry matters: the ETH leg of your swap is the expensive part. Sending ETH during congestion can cost more than the entire ADA-side settlement combined, so timing the deposit transaction is where you actually save money.

Liquidity for this pair is deep across aggregated providers because both assets sit in the top 15 by market cap, but quoted rates still vary by 1-3% between services due to differing internal routing (some go ETH -> BTC -> ADA, others ETH -> USDT -> ADA, a few hold direct inventory). The comparison table above surfaces those spreads in real time.

Choosing a service for this pair

• Network match: confirm the ADA address is a native Cardano Shelley address (starts with 'addr1'), not a wrapped ADA token on BSC or Ethereum.
• Rate type: floating rates track market and usually quote better; fixed rates lock for 10-15 minutes and protect you if ETH moves during confirmation.
• Min/max: ETH -> ADA minimums are typically 0.01-0.02 ETH; very small swaps get eaten by network fees.
• Refund address: always supply an ETH refund address in case the deposit arrives outside the rate window.

Practical tips: send ETH when base fee is under 20 gwei (check a gas tracker before initiating), size your swap so the ETH gas is under 1% of the trade, and verify the destination ADA address character-by-character - Cardano addresses are long and a single typo routes funds irrecoverably. If you plan to stake, send to a wallet you control (Eternl, Lace, Yoroi), not directly to an exchange deposit address.
