Sell USDC on Base without moving through an exchange first.
If your USDC is already on Base, the cleanest off-ramp is often not a centralized exchange. USDCtoFiat lets you publish a sell deposit, choose the payment app and currency you want, and keep settlement in a public Base contract until buyer payment is proven.
Native USDC on chain ID 8453, not wrapped USDC from another network.
Venmo, Cash App, Chime, Revolut, Wise, Zelle, PayPal, Monzo, N26, and Luxon.
The three currencies the app settles, across the supported payment apps.
No platform fee to publish a sell deposit; Base gas still applies.
Best fit
USDCtoFiat is built for sellers who already hold native USDC on Base and want fiat to land in a payment app rather than a crypto exchange account. The buyer pays your Venmo username, Cashtag, Revtag, Wisetag, PayPal.me, Zelle email, or other supported identifier directly.
This is a different job than a classic fiat ramp. A ramp provider optimizes broad card and bank coverage; USDCtoFiat optimizes the onchain seller flow, payment-app settlement, and verifiable P2P escrow.

When Base matters
| Situation | Why USDCtoFiat fits |
|---|---|
| USDC is already on Base | No need to send assets through a centralized exchange just to reach a fiat payout route. |
| You want payment-app balance | The buyer pays the app account you specify instead of routing everything through a card or bank withdrawal. |
| You know the buyer | Private OTC orders restrict a deposit to one approved wallet and generate a single share link. |
| You want visible settlement logic | Deposit creation, buyer intent, hook attachment, and release happen through public Base contracts. |
When another route may win
Use a centralized exchange or institutional OTC desk when you need a predictable large bank withdrawal, formal account statements, or guaranteed liquidity at a specific time. P2P settlement is only as fast as buyer demand for your payment method, currency, and rate.
Use a regulated fiat ramp when the user needs a familiar KYC checkout, card payout, or broad country coverage more than a non-custodial Base-native trade.
Native USDC, public escrow, direct fiat payment.
The seller-facing contract path is inspectable on Base, while fiat settlement happens directly between buyer and seller on the selected payment platform.
USDCtoFiat does not guarantee fill speed. Liquidity depends on buyer demand for the selected payment method and currency.

Common questions
What is USDCtoFiat?
USDCtoFiat lets you sell USDC on Base for money in Venmo, Cash App, Chime, Revolut, Wise, Zelle, PayPal, Monzo, N26, and Luxon. You keep control of your wallet, and trades settle through non-custodial ZKP2P smart contracts on Base.
Does USDCtoFiat hold my funds?
No. You sign every transaction from your own wallet. Your USDC is locked in a public Base contract and releases to the buyer only after their payment is proven. You can withdraw any unfilled deposit at any time.
What does it cost to sell?
Creating and managing a seller deposit is free, though Base gas applies to onchain actions. The offramp SDK is free to integrate. On delegated fills, Delegate's 0.10% manager fee comes from the USDC released to the buyer, not from your fiat proceeds or your quoted rate. Peerlytics analytics, webhooks, and API credits are priced separately.
Do I need a centralized exchange account?
No exchange account is required to use USDCtoFiat. You need a wallet holding USDC on Base and an account on the payment app you want to be paid in. The payment app's own account rules and limits still apply.
Do I need to complete KYC?
USDCtoFiat does not collect identity documents, hold your fiat, or hold your keys. The payment app you use still controls its own verification, limits, and account rules. USDC settlement happens through Base smart contracts, and we cannot change what Venmo, PayPal, Wise, Zelle, or your bank requires.
Can I sell USDC on Base directly to a bank account?
USDCtoFiat sends fiat through supported payment apps rather than directly initiating bank payouts. Some payment apps, such as Zelle, Wise, Revolut, Monzo, or N26, may themselves connect to bank accounts depending on your region and account setup.
Do I need to bridge USDC to Base first?
Yes. The sell flow uses native USDC on Base. If your USDC is on Ethereum, Arbitrum, Optimism, Solana, or another network, bridge or transfer it to Base before creating a sell deposit.
How fast does a deposit fill?
Fill speed depends on buyer demand for your payment method, currency, and rate. Liquid routes like USD via Venmo or Cash App, or EUR/GBP via Revolut or Wise, move fastest. You can withdraw unfilled deposits whenever you want.
