Constants

Functions

func AddAllUTXOs

func AddAllUTXOs(
	ctx context.Context,
	utxos walletcommon.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.

func MakeWallet

func MakeWallet(ctx context.Context, config *WalletConfig) (Wallet, error)

MakeWallet returns a wallet that supports issuing transactions to the chains living in the primary network.

On creation, the wallet attaches to the provided uri and fetches all UTXOs that reference any of the provided keys. 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 will also fetch all requested P-chain transactions.

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

func NewWallet

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

Creates a new default wallet

func NewWalletWithOptions

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

Creates a Wallet with the given set of options

type WalletConfig

type WalletConfig struct {
	// Base URI to use for all node requests.
	URI string // required
	// Keys to use for signing all transactions.
	AVAXKeychain keychain.Keychain // required
	EthKeychain  c.EthKeychain     // required
	// Subnet IDs that the wallet should know about to be able to generate
	// transactions.
	SubnetIDs []ids.ID // optional
	// Validation IDs that the wallet should know about to be able to generate
	// transactions.
	ValidationIDs []ids.ID // optional
}
