ADA
ETH
Swap Cardano (ADA) to Ethereum (ETH)
Cardano and Ethereum have no native bridge between them, so a swap is the direct route: ADA goes in, native ETH comes out on Ethereum mainnet at your 0x address.
Cardano โ Ethereum: when it makes sense
Cardano and Ethereum do not share a native bridge, so ADA to ETH is usually done through an exchange account or a swap service like this one. The swap route is one order: ADA leaves your Cardano wallet, ETH arrives on Ethereum mainnet. The mistake to avoid is on the ETH side โ the same 0x address exists on Arbitrum, Base and other L2s, and people look for the ETH on the wrong network.
Cardano's eUTXO model makes fees predictable before you sign, which is handy when you swap an exact amount.
ETH is also the gas token for every ERC20 transfer, so swapping all of your ETH away can leave tokens stuck in a wallet with no gas.
Cardano vs Ethereum: the networks side by side
| ADA | ETH | |
|---|---|---|
| Network | Cardano mainnet (eUTXO) | Ethereum mainnet (proof of stake) |
| Blocks / confirmation | a block about every 20 seconds on average | 12-second slots; full finality after two epochs, about 13 minutes |
| Address format | addr1โฆ (Shelley); old Byron addresses start with Ae2 or DdzFF | 0xโฆ (42 hex characters) |
| Network fee | about 0.17โ0.2 ADA for a simple transfer | gas paid in ETH; varies with network demand, usually cheapest at weekends and night hours UTC |
| Memo / tag | not used | not needed to receive |
| Wallets | Eternl, Lace, Yoroi, Vespr, Ledger | MetaMask, Rabby, Trust Wallet, Ledger, Trezor |
KOT.CASH vs a centralised exchange for ADA โ ETH
| KOT.CASH | Centralised exchange | |
|---|---|---|
| Account & KYC | No sign-up; no ID documents for standard swaps | Account required; regulated exchanges must verify identity |
| Steps | One order: send ADA, receive ETH at your own address | Deposit ADA โ wait for credit โ trade โ request ETH withdrawal |
| Custody | Funds pass through the service only for the swap | Funds sit in the exchange account until you withdraw |
| Withdrawal | Automatic once the deposit is confirmed | Withdrawal fee; limits, holds or extra checks are possible |
| Cost | 1% float or 1.5% fixed + network fees; final amount shown upfront | Trading fee, spread and withdrawal fee โ vary by exchange and volume |
| Where a CEX is better | No fiat, limit orders or margin โ crypto-to-crypto swaps only | Fiat on/off-ramp, limit orders, very large volumes |

Step-by-step guides
How to swap ADA to ETH, step by step
- 1
Select ADA โ ETH in the widget and enter the amount. It shows the current minimum, the ETH you will receive and the rate type (1% float or 1.5% fixed) before anything is sent.
- 2
Paste your ETH address โ 0xโฆ (42 hex characters). Copy it from your wallet (MetaMask, Rabby, Trust Wallet, Ledger, Trezor) and compare the first and last characters.
- 3
Create the order and send exactly the shown amount of ADA to the deposit address. Bookmark the order link โ it shows the live status.
- 4
Wait for confirmations: a block about every 20 seconds on average. The liquidity provider sets how many are required; the order page shows the live count.
- 5
ETH is sent to your address automatically. On the receiving side: 12-second slots; full finality after two epochs, about 13 minutes. The transaction hash appears on the order page.
Common ADA โ ETH mistakes
Every Cardano output must carry a minimum of roughly 1 ADA, so very small sends and 'send all' with native tokens attached can fail.
Staking does not lock ADA โ delegated ADA can be sent at any time, no unbonding needed.
The same 0x address exists on Arbitrum, Base, Optimism and BNB Chain. ETH sent from an L2 is not mainnet ETH โ send from Ethereum mainnet only.
Leave some ETH for gas if you will move other tokens from the same wallet later.
ADA to ETH: questions people ask
Is ADA to ETH a taxable event?
In many countries swapping one crypto for another is a disposal for tax purposes. Rules differ by country; check your local tax authority's guidance.
How long does ADA to ETH take?
The Cardano deposit needs several confirmations (blocks about every 20 seconds), then the ETH payout confirms in about 12 seconds per Ethereum block.
How long do ADA confirmations take?
A block about every 20 seconds on average. The liquidity provider decides how many confirmations are required; the order page shows the live count.
Will the ETH arrive on Arbitrum or Base?
No. ETH is delivered on Ethereum mainnet. The same 0x address exists on L2s, so switch your wallet to Ethereum to see it.
Do I need ETH to receive ETH?
No. Receiving is free for you; the payout transaction fee is already included in the quote.
Are wrapped ADA tokens on Ethereum the same?
No. This pair takes native ADA on Cardano only.

ADA and ETH networks: confirmations and memo
Built from the liquidity provider's network list as of 2026-10-20. "Confirmations" is how many blocks the provider waits for before crediting a deposit; the order page shows the exact number for your order. If the memo column names a tag, a deposit without it cannot be matched automatically.
