Constants

const LedgerScheme = "ledger"

LedgerScheme is the protocol scheme prefixing account and wallet URLs.

const TrezorScheme = "trezor"

TrezorScheme is the protocol scheme prefixing account and wallet URLs.

Variables

var ErrTrezorPINNeeded = errors.New("trezor: pin needed")

ErrTrezorPINNeeded is returned if opening the trezor requires a PIN code. In this case, the calling application should display a pinpad and send back the encoded passphrase.

Types

type Hub

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

todo Hub结构体实现了Backend接口，是usbwallet类型的钱包的后端实现.

Hub结构体代表了这种类型的后端钱包，它主要由函数 NewLedgerHub() 或 NewTrezorHub() 创建，根据不同的driver，它可以代表不同的硬件钱包.

这也是 makeDriver 字段想要表达的意思. 在ledger.go和trezor.go中，有各自的driver实现，它们使用不同的协议，todo 通过 device.Write() 和 io.ReadAll() 对设备进行读写以实现通信

Hub is a accounts.Backend that can find and handle generic USB hardware wallets.

func NewLedgerHub

func NewLedgerHub() (*Hub, error)

NewLedgerHub creates a new hardware wallet manager for Ledger devices.

func NewTrezorHub

func NewTrezorHub() (*Hub, error)

NewTrezorHub creates a new hardware wallet manager for Trezor devices.

func (*Hub) Subscribe

func (hub *Hub) Subscribe(sink chan<- accounts.WalletEvent) event.Subscription

Subscribe implements accounts.Backend, creating an async subscription to receive notifications on the addition or removal of USB wallets.

func (*Hub) Wallets

func (hub *Hub) Wallets() []accounts.Wallet

Wallets implements accounts.Backend, returning all the currently tracked USB devices that appear to be hardware wallets.
