# Unreal Ecosystem Wallet Authentication
> Ecosystem Wallet Documentation for Sequence's Unreal SDK.
Start with an implicit session which is restricted to contracts built by Sequence.
Alternatively, you can choose to add a [Permissions](/sdk/unreal/wallets/ecosystem-wallet/permissions) object to each Sign In call, if you want to connect to an
explicit session directly.
