You might have some USDC in a personal digital wallet and want to move it into your bank account.
Perhaps you closed a position, or you received a payment in cryptocurrency and now need local money (fiat) to cover everyday costs.
Whatever the reason, converting USDC to your local currency is a manageable process if you follow a few simple steps.
Understanding stablecoins
USDC is a stablecoin. This means it is a type of crypto‑asset that aims to keep a stable value by tracking an external asset, usually a fiat currency such as the US dollar (USD).
Think of it like travelling abroad. If you travel to Japan and exchange pounds for yen, you can spend yen in Japan. But back home, you will need to swap the yen back to pounds before you can use it at your local shop.
How it works in practice
Cashing out your USDC through CoinJar involves several steps.
Create a CoinJar account
If you do not already have a CoinJar account, you will need to sign up.
You will be asked for some personal details and to complete identity verification (KYC). This may include providing proof of identity and address, in line with Financial Conduct Authority (FCA) anti-money-laundering and know-your-customer requirements.
Your account must be fully verified before you can deposit, trade, or withdraw. As a first-time crypto investor, you'll also be asked to complete an appropriateness assessment and observe a 24-hour cooling-off period before you can transact, in line with FCA rules.
Transfer your USDC to CoinJar
Once your account is verified, you can move your USDC from your external wallet to your CoinJar wallet.
- In the CoinJar app, tap the Transfer button and go to the Deposit Crypto section and choose USDC. USDC is supported on the Ethereum network and on the Solana network. Make sure you select a compatible network. Transfers on the blockchain cannot be reversed.
Important: If you send USDC to the wrong address or on the wrong network, you are likely to lose those funds permanently. It is advisable to send a small test amount first before sending the rest.
- CoinJar will show you a USDC deposit address. Press Copy USDC Address.
- From your external wallet, send USDC to this address, making sure you select the same network that CoinJar supports for USDC.
Sell your USDC for your local currency
When the USDC has arrived in your CoinJar wallet, you can trade it for fiat.
- Go to the trade or sell section. Then, tap Sell.
- Tap the drop‑down menu to choose the cryptocurrency. In this case, it is USDC.
- Enter how much USDC you want to sell.
- Tap Review Order. Review it, making sure you understand the fees, then confirm the trade.
After the trade is completed, your CoinJar account balance will show your USDC amount has decreased, and your pound sterling amount has increased.
Withdraw your fiat currency to your bank account
Now you can move your fiat funds from CoinJar to your bank.
- Tap the Transfer button, and select Withdraw Cash.
- Choose Pounds sterling.
- Enter the withdrawal amount and your bank account details. If you already have a bank account linked to your CoinJar account, choose it from the Available Payment Methods section.
- Review any fees and estimated processing times, then confirm the withdrawal.
Staying safe and compliant
Security risks and red flags
Keeping your funds secure throughout the process is essential. Please pay attention to the following:
- Double‑check wallet addresses before every blockchain transfer. Blockchain transactions cannot be reversed if you send funds to the wrong address.
- Make sure you choose the correct network when moving USDC. Sending funds on an unsupported network can result in permanent loss.
- Do not rely on links sent via email, social media, or private messages. Always access CoinJar by typing the official address into your browser or using the official app.
- Ignore unrequested messages from people claiming to be support agents, advisers, or "recovery experts". CoinJar support will never ask for your password, security codes, or remote access to your device.
- Enable security features such as multi-factor authentication, strong unique passwords, and device security (screen lock, up‑to‑date software).
If something feels unusual, stop and contact official support through the channels listed on the CoinJar website or app.
Tax considerations
Converting crypto‑assets to fiat currency is generally treated as a taxable event by HMRC. When you sell USDC for pounds sterling you may trigger a capital gain or loss.
This depends on your acquisition cost, the disposal proceeds, and applicable UK tax rules, including your annual Capital Gains Tax allowance.
To help you stay compliant:
- Keep records of every transaction, including dates, amounts, fees, and the value in pounds sterling at the time of each trade. Consider using a crypto tax calculator to help manage this.
- Consider speaking to a qualified tax professional before making decisions.
You are responsible for understanding and meeting your own tax obligations.
Summary
To convert USDC to your local currency:
- Open and verify a CoinJar account.
- Transfer USDC from your external wallet to your CoinJar wallet, using the correct address and network.
- Sell USDC for fiat.
- Withdraw the fiat balance to your bank account, after reviewing fees and estimated processing times.
By proceeding carefully, checking every address and network, and keeping records for tax purposes, you can convert your stablecoins into traditional money in a considered and informed way.
