Swap Cardano (ADA) to USDC
Lock in ADA's dollar value as USDC without moving through an exchange account. Send ADA from Eternl, Lace or Yoroi and receive USDC on Ethereum or Solana โ the receive amount is quoted first.
ADA to USDC: what matters
ADA to USDC moves a Cardano position into dollars issued by Circle, and the real choice is the USDC network. On Solana it costs fractions of a cent to move around later; on Ethereum it plugs into the largest DeFi market but every transfer pays ETH gas. Pick by the next step, not by habit. On the Cardano side, send a little less than your full balance so the wallet can keep its minimum ADA with any tokens you hold.
Cardano's eUTXO model makes fees predictable before you sign, which is handy when you swap an exact amount.
Which USDC network to receive on
USDC exists on several blockchains. The network fee is paid in ETH (ERC20) or SOL (Solana). The rule that matters: the network must match what the wallet or service on the other side supports.
| Network | Address | Gas | Speed | Best for |
|---|---|---|---|---|
| ERC20 Ethereum | 0xโฆ (42 characters) | paid in ETH; the most expensive option when the network is busy | 12-second blocks | DeFi on Ethereum, hardware-wallet cold storage, large amounts |
| SOL Solana (SPL token) | base58, 32โ44 characters | paid in SOL; fractions of a cent, but the wallet needs a little SOL | ~0.4-second slots | native USDC issued by Circle on Solana โ cheap and fast |
Exact fees move with network load โ the widget always shows the current amount you will receive.
How to swap ADA to USDC, step by step
- 1
Select ADA โ USDC in the widget and enter the amount. It shows the current minimum, the USDC you will receive and the rate type (1% float or 1.5% fixed) before anything is sent.
- 2
Choose the USDC receive network (ERC20, SOL) and paste an address for that network. Decide by where the USDC goes next.
- 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
USDC is sent to your address automatically. On the receiving side: depends on the network you pick. The transaction hash appears on the order page.
Common ADA โ USDC 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.
Bridged versions such as USDC.e are different tokens from native USDC. Send native USDC only.
Real USDC on Ethereum is contract 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48; on Solana the mint is EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v.
Cardano vs USD Coin: the networks side by side
| ADA | USDC | |
|---|---|---|
| Network | Cardano mainnet (eUTXO) | stablecoin issued by Circle |
| Blocks / confirmation | a block about every 20 seconds on average | depends on the network you pick |
| Address format | addr1โฆ (Shelley); old Byron addresses start with Ae2 or DdzFF | 0xโฆ on Ethereum, base58 on Solana |
| Network fee | about 0.17โ0.2 ADA for a simple transfer | paid in ETH (ERC20) or SOL (Solana) |
| Memo / tag | not used | not needed to receive |
| Wallets | Eternl, Lace, Yoroi, Vespr, Ledger | MetaMask, Rabby, Ledger (ERC20); Phantom, Solflare (SOL) |
ADA to USDC: questions people ask
Will the USDC be the native Circle token?
Yes, on Ethereum and Solana USDC is Circle's native issuance, not a bridged version.
Can I sell only part of my ADA and keep delegating?
Yes. Delegation applies to the whole stake key and does not lock coins, so the remaining ADA keeps earning.
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.
Which USDC network should I choose?
Solana if the USDC stays in Phantom or Solflare and moves often; Ethereum (ERC20) if it goes to DeFi on Ethereum or a hardware wallet. Gas on Ethereum is higher.
Why does my wallet keep about 1 ADA?
Cardano outputs need a minimum amount of ADA, so sending the full balance with tokens attached can fail. Send slightly less.
USDC or USDT?
Both track the dollar. USDC is issued by Circle, USDT by Tether; pick the one your next platform supports.
Step-by-step guides
KOT.CASH vs a centralised exchange for ADA โ USDC
| 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 USDC at your own address | Deposit ADA โ wait for credit โ trade โ request USDC 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 |
| USDC network | Chosen per order: ERC20 / SOL | Depends on which withdrawal networks the exchange supports |
| 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 |
This compares how the processes work, not any specific exchange. Exchange tariffs change โ check them on the platform itself.

ADA and USDC 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.
