Functions

func AccountDetails 

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

Batch sends a batch of payments from the user to multiple recipients in a time-efficient manner.

func BatchMulti 

func BatchMulti(mctx libkb.MetaContext, walletState *WalletState, arg stellar1.BatchLocalArg) (res stellar1.BatchResultLocal, err error)

BatchMulti sends a batch of payments from the user to multiple recipients in a single multi-operation transaction.

func ChangeAccountName 

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

func CreateWalletSoft(mctx libkb.MetaContext)

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

Example: "157.5000000 XLM" Example: "12.9000000 USD" 

(where USD is a non-native asset issued by someone).

User interfaces should be careful to never give user just amount + asset code, but annotate when it's a non-native asset and make Issuer ID and Verified Domain visible. If you are coming from CLI, FormatAmountDescriptionAssetEx might be a better choice which is more verbose about non-native assets.

Example: "157.5000000 XLM" Example: "1,000.15 CATS/catmoney.example.com (GDWVJEG7CMYKRYGB2MWSRZNSPCWIGGA4FRNFTQBIR6RAEPNEGGEH4XYZ)" Example: "1,000.15 BTC/Unknown (GBPEHURSE52GCBRPDWNV2VL3HRLCI42367OGRPBOO3AW6VAYEW5EO5PM)"

func FormatAmountDescriptionAssetEx2 

func FormatAmountDescriptionAssetEx2(mctx libkb.MetaContext, amount string, asset stellar1.Asset) (string, error)

FormatAmountDescriptionAssetEx2 is like FormatAmountDescriptionAssetEx, except that it only shows one of issuer domain and issuer account ID. When issuer domain is available, the domain is shown. Otherwise account ID is used. Example: "157.5000000 XLM" Example: "1,000.15 CATS/catmoney.example.com Example: "1,000.15 BTC/GBPEHURSE52GCBRPDWNV2VL3HRLCI42367OGRPBOO3AW6VAYEW5EO5PM"

type SeqnoProvider added in v1.0.48 

type SeqnoProvider struct {
	// contains filtered or unexported fields
}

SeqnoProvider implements build.SequenceProvider. It can be used for several transactions in a row.

func NewSeqnoProvider added in v1.0.48 

func NewSeqnoProvider(mctx libkb.MetaContext, walletState *WalletState) (seqnoProvider *SeqnoProvider, unlock func())

NewSeqnoProvider creates a SeqnoProvider. It also returns an `unlock` function that must be called after the operation(s) that used this seqno provider have been submitted.

The idea here is to fix a race where multiple calls to send payments will make a SeqnoProvider and while they will consume seqnos in order, they are not guaranteed to be submitted in order. In particular, the `dust storm` function in the bot has a tendency to expose the race.
