How to Buy ETH with USD: Alternatives to CEX

There is no need to manage multiple exchange accounts or manually compare platforms.

Who this approach is best for

Buying ETH via an exchange aggregator can be a good fit for users who:

• Want to avoid registering on centralized exchanges
• Prefer non-custodial swaps
• Value the ability to compare multiple offers in one place
• Need flexibility around KYC requirements

Final thoughts

Centralized exchanges remain a common entry point for buying ETH with USD, but they are not the only option. Exchange aggregators like SwapSpace offer a more flexible approach by combining multiple providers, real-time pricing, and user-controlled choices in a single interface.

For users who prioritize convenience, transparency, and optional privacy, this model can be a practical alternative to traditional CEXs.

FAQCan I buy ETH with USD without using a centralized exchange？

Yes. Instead of using a centralized exchange, you can buy ETH through crypto exchange aggregators or fiat on-ramps. These services compare offers from multiple providers and let you complete a purchase without opening an exchange account.

Is KYC required to buy ETH with USD？

It depends on the provider you choose. Some offers require identity verification, while others allow purchases without KYC. Exchange aggregators make this transparent by showing KYC requirements before you proceed.

Do I need a crypto wallet to buy ETH？

Yes. To receive ETH, you need an Ethereum-compatible wallet such as MetaMask, Trust Wallet, or a hardware wallet. When using an aggregator, ETH is usually sent directly to your wallet rather than held by a platform.

What is the difference between fixed and floating rates？

A fixed rate guarantees the exact amount of ETH shown before the exchange starts. A floating rate follows market conditions and may change slightly during the transaction, sometimes resulting in a better final price.

Is using an exchange aggregator safe？

Exchange aggregators do not hold user funds. They connect users with established exchange providers and display real-time offers. Safety depends on choosing reputable partners and following basic security practices, such as verifying wallet addresses.
