At the moment, you cannot deposit or withdraw fiat money (such as EUR or USD) directly into Peccala.
You first need to buy USDT or USDC on a crypto exchange (e.g. Coinbase, Kraken, Binance, KuCoin) and then transfer those tokens to your Peccala wallet.
When you withdraw, you will receive USDT (or USDC if you convert before withdrawing), which you can then send to your exchange and convert back into fiat currency.
