Though many people will use Sei with 0x addresses, the native address for Sei is also used.
For example, Kraken uses the native Sei address. This results in the confusing "withdrawal address is invalid" error.
Sei links a native Sei address with an EVM address.
Go to https://app.sei.io/ and log in to the app using your EVM wallet (Rabby, Metamask, Phantom, etc). You'll then see your linked native Sei account address.
Use the native Sei address with Kraken.
Send a small amount of Sei as a test transaction first. You should see the Sei on your Rabby or other EVM wallet.
https://welcome.symph.ag/ is good welcome page for people new to Sei. It has a built-in dex for swapping to Sei from another blockchain's currency and a dex integration for Sei ecosystem tokens.
