Kryptonim Fiat-to-Crypto Platform: Key Features and Specifications
1. Kryptonim

Supported Local Currencies
Kryptonim supports 27 fiat currencies, making it accessible to users worldwide. Among the options are major currencies like the US dollar (USD), euro (EUR), and British pound sterling (GBP), alongside regional choices such as the Polish zloty (PLN), Brazilian real (BRL), Mexican peso (MXN), and Vietnamese dong (VND). The minimum transaction amount is set at 10 EUR (around $10.75) across all supported currencies. While the service operates globally, it excludes residents of Afghanistan, Belarus, Cuba, Iran, North Korea, Russia, and Syria. Additionally, users in the United States, United Kingdom, and Canada must provide a billing address along with their email during the checkout process.
Fiat Payment Methods
Kryptonim offers a variety of payment methods to suit different preferences. You can purchase cryptocurrency using credit or debit cards (Visa, MasterCard, Maestro) or via bank transfers through Volt for EUR transactions. Card payments are typically processed within 2 to 20 minutes, while bank transfers may occasionally take up to 3 business days. Mobile users can enjoy the convenience of one-tap purchases through Apple Pay and Google Pay. For European customers, SEPA and SEPA Instant transfers provide a cost-efficient way to complete transactions.
Transaction Fees
The platform applies a 2% fee for EU users and a 4% fee for users in other regions. These fees include a processing charge and a variable network fee, which depends on blockchain congestion at the time. Because the exchange rate is locked in when the payment is received - not when the order is placed - the amount of cryptocurrency you receive might differ from the initial estimate due to market fluctuations. To reduce the risk of price slippage, it’s better to use card payments instead of bank transfers. This fee structure ensures a transparent and straightforward purchasing process.
User Accessibility
Kryptonim stands out by not requiring account creation, though users must complete identity verification to comply with AML/KYC regulations. This involves submitting a government-issued ID and completing facial recognition. As a non-custodial platform, Kryptonim requires users to provide their own external wallet address - such as MetaMask, Trust Wallet, or Coinbase Wallet - for receiving cryptocurrency. Before making a purchase, double-check that your wallet supports the blockchain network of the asset you’re buying. Supported networks include Ethereum, Polygon, Avalanche, Optimism, Arbitrum, Base, Bitcoin, Solana, and Tron.

FAQs
Do I need a crypto wallet before buying on Kryptonim?
No, you don’t need a crypto wallet to make purchases on Kryptonim. The platform simplifies the process by enabling quick fiat-to-crypto transactions without requiring you to create an account or set up a wallet. This makes it especially convenient for beginners. However, if you plan to store, send, or receive cryptocurrencies after your purchase, you’ll need to set up a crypto wallet.
Why can the final crypto amount differ from the estimate?
The final cryptocurrency amount you receive might differ from the initial estimate. This happens because of factors like transaction fees, charges tied to your payment method, or costs specific to the platform you're using. These deductions can lower the actual amount that ends up in your wallet.
What documents are needed for identity verification?
To confirm your identity on fiat-to-crypto platforms like Kryptonim, you'll generally need to provide a valid, government-issued photo ID. This could be a passport, driver’s license, or national ID card. Additionally, some platforms might ask for proof of address, such as a recent utility bill or bank statement dated within the last three months. The verification process often involves uploading these documents and completing a facial verification step to ensure an extra layer of security.
