💳Wallet Methods

To know Web3 wallet relevant methods in Startrail-Sdk-Js

login

Authenticate a user and allocate EOA.

Following arguments can be passed to overwrite the configuration originally set at the instantiation.

Arguments

Parameter	Type	Mandatory	Description
authAction	{ login: boolean signup: boolean }	Optional	Client ID of Auth0 account

Returns

Promise<string[] | false>: An object containing user information.

Distinct EOAs are assigned for each login provider, regardless of whether the same email is utilized for authentication methods, such as Google and Email Passwordless.

To prevent duplicate registration of accounts with the same email and different EOAs, it is recommended that your application rejects duplicate email registrations on your application side.

About Page reload and data persistency

• Wallet information is stored in browser session storage under Torus service domain.

• As SDK instance is gone at page reload, it's no longer available unless it is instantiated again. User, however, does not require additional login process to trigger its function call since the session between Torus node and Authenticator keeps maintained until sdk.logout function is called
