Create an account at a crypto exchange

Create an account at a crypto exchange of your choice OKX (currently offering the lowest SEI price). Sign up with email and password. In most cases, the next step is an identity verification process, so it’s best to have your ID card or passport ready.

2.

Add a payment method

Add your preferred payment method to your account. Depending on the exchange, you can choose between credit card, bank transfer, or instant payment options. Some exchanges also support PayPal or Apple Pay, although these usually come with slightly higher fees.
