- Boundless wallet: managed for you. You sign in and the platform signs transactions on your action. There’s no seed phrase to look after. This is the simplest option and the default for most people.
- External wallet: a self-custody wallet such as Freighter, where you hold the keys and sign transactions yourself. Useful if you’re already crypto-native and want to control your own funds.
