Sell USDC for GBP to your monzo.me username.

Monzo describes monzo.me as a way for friends and family to settle bills, gifts, and reimbursements. Personal accounts must not be used for business, while regulated-exchange crypto transfers have separate limits. Technical ZKP2P support does not override those account rules.

What to check before considering Monzo

Comparing personal GBP payment links with eligible regulated-exchange routes.

Fiat moves directly between buyer and seller through the payment platform, while the USDC leg settles through ZKP2P smart contracts on Base.

How the technical route works

01Confirm that Monzo's current account rules permit the intended payment.
02Connect a wallet holding native USDC on Base.
03Choose Monzo as the payment method and select GBP.
04Use your monzo.me username, not a private note or bank detail that cannot be paid from the buyer flow.
05Approve and create the smart-contract deposit.
06Monzo payment proof has to match the GBP amount, payee, and order context before USDC releases from the Base contract.

Risks to manage

Fill speed depends on buyer demand for the exact method, currency, and rate.
The external payment platform can apply its own account limits, reviews, reversals, and KYC rules.
Never release manually from a screenshot alone. Check the payment inside your own account first.
Withdraw unfilled USDC if the rate is stale, your account is under review, or you no longer want the order public.

Common questions

Can I cash out USDC to Monzo?

The protocol has technical Monzo support, but that does not mean every crypto-sale payment is permitted. Review Monzo's current account-purpose rules first; if they do not allow the intended transfer, choose another eligible route.

Does USDCtoFiat hold my Monzo funds?

No. Fiat moves directly through Monzo. USDCtoFiat does not custody fiat, does not log into your payment account, and cannot reverse external payment-app transfers.

What is USDCtoFiat?

USDCtoFiat coordinates non-custodial sales of native Base USDC across the current ZKP2P payment and currency catalog, including USD, EUR, GBP, INR, and CNY. Payment-provider eligibility and account policies still apply; technical route support is not permission to use an external account, and Wise currently prohibits P2P crypto-sale receipts.

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. 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.

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.

How fast does a deposit fill?

Fill speed depends on buyer demand for your payment method, currency, rate, and order size. Check live liquidity for an eligible route before publishing; technical support does not override a provider's account rules. You can withdraw unfilled deposits whenever you want.
