Functions

func AccountExchangeRate 

func AccountExchangeRate(mctx libkb.MetaContext, remoter remote.Remoter, accountID stellar1.AccountID) (stellar1.OutsideExchangeRate, error)

AccountExchangeRate returns the exchange rate for an account for the logged in user. Note that it is possible that multiple users can own the same account and have different display currency preferences.

func ChangeAccountName 

func ChangeAccountName(m libkb.MetaContext, accountID stellar1.AccountID, newName string) (err error)

ChangeAccountName changes the name of an account. Make sure to keep this in sync with ValidateAccountNameLocal. An empty name is not allowed. Renaming an account to an already used name is blocked. Maximum length of AccountNameMaxRunes runes.

func ChatSendPaymentMessage 

func ChatSendPaymentMessage(m libkb.MetaContext, recipient stellarcommon.Recipient, txID stellar1.TransactionID) error

func Claim 

func Claim(ctx context.Context, g *libkb.GlobalContext, remoter remote.Remoter,
	txID string, into stellar1.AccountID, dir *stellar1.RelayDirection,
	autoClaimToken *string) (res stellar1.RelayClaimResult, err error)

Claim claims a waiting relay. If `dir` is nil the direction is inferred.

func CreateNewAccount 

func CreateNewAccount(m libkb.MetaContext, accountName string) (ret stellar1.AccountID, err error)

func CreateWallet 

func CreateWallet(ctx context.Context, g *libkb.GlobalContext) (created bool, err error)

CreateWallet creates and posts an initial stellar bundle for a user. Only succeeds if they do not already have one. Safe (but wasteful) to call even if the user has a bundle already.

func CreateWalletGated 

func CreateWalletGated(ctx context.Context, g *libkb.GlobalContext) (justCreated, hasWallet bool, err error)

CreateWalletGated may create a wallet for the user. Taking into account settings from the server and env. It should be speedy to call repeatedly _if_ the user gets a wallet. `hasWallet` returns whether the user has by the time this call returns.

func CreateWalletSoft 

func CreateWalletSoft(ctx context.Context, g *libkb.GlobalContext)

CreateWalletSoft creates a user's initial wallet if they don't already have one. Does not get in the way of intentional user actions.

func DeleteAccount 

func DeleteAccount(m libkb.MetaContext, accountID stellar1.AccountID) error

func ExportSecretKey 

func ExportSecretKey(ctx context.Context, g *libkb.GlobalContext, accountID stellar1.AccountID) (res stellar1.SecretKey, err error)

func FormatPaymentAmountXLM(amount string, delta stellar1.BalanceDelta) (string, error)

func GetAccountDisplayCurrency 

func GetAccountDisplayCurrency(mctx libkb.MetaContext, accountID stellar1.AccountID) (res string, err error)

GetAccountDisplayCurrency gets currency setting from the server, and it returned currency is empty (NULL in database), then default "USD" is used. When creating a wallet, client always sets default currency setting. Also when a new account in existing wallet is created, it will inherit currency setting from primary account (this happens serverside). Empty currency settings should only happen in very old accounts or when wallet generation was interrupted in precise moment.

func GetCurrencySetting 

func GetCurrencySetting(mctx libkb.MetaContext, remoter remote.Remoter, accountID stellar1.AccountID) (res stellar1.CurrencyLocal, err error)
