Functions

func AddAllUTXOs 

func AddAllUTXOs(
	ctx context.Context,
	utxos UTXOs,
	client UTXOClient,
	codec codec.Manager,
	sourceChainID ids.ID,
	destinationChainID ids.ID,
	addrs []ids.ShortID,
) error

AddAllUTXOs fetches all the UTXOs referenced by [addresses] that were sent from [sourceChainID] to [destinationChainID] from the [client]. It then uses codec to parse the returned UTXOs and it adds them into [utxos]. If [ctx] expires, then the returned error will be immediately reported.

Output:

func NewWallet 

func NewWallet(p p.Wallet, x x.Wallet) Wallet

Creates a new default wallet

func NewWalletFromURI 

func NewWalletFromURI(ctx context.Context, uri string, kc *secp256k1fx.Keychain) (Wallet, error)

NewWalletFromURI returns a wallet that supports issuing transactions to the chains living in the primary network to a provided [uri].

On creation, the wallet attaches to the provided [uri] and fetches all UTXOs that reference any of the keys contained in [kc]. If the UTXOs are modified through an external issuance process, such as another instance of the wallet, the UTXOs may become out of sync.

The wallet manages all UTXOs locally, and performs all tx signing locally.

func NewWalletWithOptions 

func NewWalletWithOptions(w Wallet, options ...common.Option) Wallet

Creates a Wallet with the given set of options

func NewWalletWithState 

func NewWalletWithState(
	uri string,
	pCTX p.Context,
	xCTX x.Context,
	utxos UTXOs,
	kc *secp256k1fx.Keychain,
) Wallet

Creates a wallet with pre-fetched state.

func NewWalletWithTxs added in v1.8.4 

func NewWalletWithTxs(ctx context.Context, uri string, kc *secp256k1fx.Keychain, preloadTXs ...ids.ID) (Wallet, error)

Creates a wallet with pre-loaded/cached P-chain transactions.

func NewWalletWithTxsAndState added in v1.8.4 

func NewWalletWithTxsAndState(
	uri string,
	pCTX p.Context,
	xCTX x.Context,
	utxos UTXOs,
	kc *secp256k1fx.Keychain,
	pTXs map[ids.ID]*txs.Tx,
) Wallet

Creates a wallet with pre-loaded/cached P-chain transactions and state.
